Altech Chemicals Launches Silumina Anodes Product Name

THE BOURSE WHISPERER: Altech Chemicals (ASX: ATC) has registered the product name Silumina AnodesTM for the company’s alumina coated composite silicon/graphite lithium-ion battery anode material.

From test work results, Altech expects its Silumina AnodesTM product to provide for the manufacture of battery anodes, that when incorporated into a lithium-ion battery, will result in a battery with higher energy retention capacity by volume and weight compared to a battery using a graphite only battery anode.

The key differentiation point of Silumina AnodesTM is that it will be a composite material of silicon and graphite particles that have been coated with alumina, using Altech’s proprietary alumina coating technology.

Altech’s laboratory test work demonstrated lithium-ion batteries using an anode comprised of composite graphite and silicon particles coated with alumina, improved battery energy capacity, energy retention, life and performance when compared to using a graphite only anode.

In November 2021, Altech achieved a breakthrough when its R&D team “cracked the silicon barrier”, producing lithium-ion battery anode materials with approx. 30 per cent higher energy retention capacity compared to conventional graphite only lithium-ion battery anode material.

The need to increase lithium-ion battery energy density and reduced cost has been a hurdle the lithium-ion battery industry has long wanted to clear.

Silicon metal has been considered the most promising anode material for the next generation of lithium-ion batteries, but, until now was unable to be used in commercial lithium-ion batteries.

Altech’s potentially game changing technology has demonstrated that silicon particles can be modified to resolve capacity loss caused by swelling and first-cycle-loss capacity.

Phase 2 of Altech’s planned R&D program will see the company strive to improve on the 30 per cent energy increase achieved in the first phase.

Altech Chemicals Commences German Battery Materials PFS

THE BOURSE WHISPERER: Altech Chemicals (ASX: ATC) via its 75 per cent-owned German subsidiary, Altech Industries Germany, has commenced a pre-feasibility study (PFS) for construction of a battery materials high purity alumina (HPA) coating plant in Saxony, Germany.

The PFS will assume a phase 1 coating plant designed with the capacity to coat 10,000 tonnes per annum (35 tonnes per day) of anode graphite, using Altech’s alumina coating technology.

“HPA is commonly applied as a coating on the separator sheets used within a lithium-ion battery, as alumina coated separators improve battery performance, durability and overall safety,” Altech Chemicals explained in its ASX announcement.

“However, evolving demand for alumina within the anode component of the lithium-ion battery has been identified because of the potential positive impacts that alumina coated graphite and silicon particles may have on lithium-ion battery life and performance.”

The study will assume the use of 100 per cent renewable power from the local grid with some minor on-site solar generation for buildings.

The design will target green project status.

It is planned that once the PFS is completed, the project will be accessed for green accreditation by the Centre of International Climate and Environmental Research (CICERO), Norway.

Altech Chemicals Explains High Purity Alumina Use in Semi-Conductor Applications

THE BOURSE WHISPERER: Sometimes a company announcement comes along that needs to be brought to the attention of punters, simply due to the information it presents.

Altech Chemicals Limited (ASX: ATC) released such an announcement today; one that provides information regarding the use of high purity alumina (HPA) in the manufacture of epoxy moulding compounds (EMCs) that are used in the semi-conductor industry to improve heat dissipation.

Altech recently commenced an investigation of the EMC for semi-conductor market for the purpose of targeting some of its future HPA product into this market segment.

The information below is straight from the announcement. There has been no editing by The Resources Roadhouse as we feel it tells the story in a much more knowledgeable fashion than we could.

Introduction of alumina into EMCs used in semi-conductors

Typically industrial-strength epoxy compounds are used for the package assembly of semi-conductors, as the epoxy compounds provide the required physical protection, mechanical strength, as well as a number of desired performance properties – primarily in relation to heat and moisture, both of which can destroy a semi-conductor, warp an electronic device (that the semi-conductor is used in), or even cause a device to catch fire.

Electronic devices continue to become more compact – Moore’s Law – the exponential growth in the number of transistors that can be packed into a single semi-conductor.

However, thermal or heat dissipation is a real problem as semi-conductors continue to reduce in size and contain more transistors.

It is suggested that heat could represent the ultimate barrier to the ever smaller and more powerful semi-conductors that end-users have become accustomed to.

The epoxy resins that have traditionally been used for semi-conductor package assembly are reaching their limits in terms of effective heat dissipation.

However, adding thermally conductive materials into the resins has been demonstrated to improve heat dissipation and thereby improve the protection of semi-conductors against heat related failure.

The thermally conductive fillers that are being used include HPA, crystalline silica, and magnesium oxide.

HPA however is a preferred filer, due to its heat conductivity (7 times higher than silica) and a much lower thermal expansion coefficient (50% lower).

Figure 1 below illustrates a typical semi-conductor chip encased in an epoxy resin compound with HPA used as a thermal filler.

The heat produced from a semi-conductor chip and the die pad more efficiently dissipates via the alumina rich epoxy resin and lowers thermal stress related problems for the semi-conductor and the assembly package (integrated circuit board).

Figure 2 below is a scanning electron microscope (SEM) image of HPA used as a filler material in an epoxy resin moulding compound. The image demonstrates the efficiency of the conductive filler within the epoxy resin package.

The purity of the material selected as the conductive filler in an epoxy resin for use in the semi-conductor industry is extremely important, consequently there are very stringent (and low) limits on the impurities permitted in the chosen filler.

Of the impurities, sodium is probably the most detrimental element.

Radioactive material is another detrimental impurity, as gamma rays from an impurity such as thorium increases the likelihood of semi-conductor and/or CPU malfunction.

Thorium is present in bauxite, the traditional feedstock used for the production of aluminium.

A small amount of thorium residue will remain in any HPA produced via the conventional bauxite – alumina – aluminium production process (Bayer process).

Thorium is not present in HPA that is produced from Altech’s kaolin HCL processing route.

Special morphologies (crystal form, shape and structure) are also demanded of the EMC filler, in the case of HPA the industry requires a morphology that is conducive to low viscosity, an attribute that is favourable in the epoxy resin packaging process.

Altech’s preliminary investigation into the demand for high quality HPA from the EMC semi-conductor market indicates a global market size in the range of 700 – 900tpa, with a price of US$100/kg being commanded by product that meets required specifications.

Year-on-year growth in the market is typically in line with growth experienced in the semi-conductor business.

Altech believes that its low sodium HPA, and the morphology of its HPA, may be ideal for the EMC semi-conductor application, and the company intends to commence the development of a product specification that may suit this market sector’s requirements.

Altech Chemicals Invited to German HPA Party

THE BOURSE WHISPERER: Altech Chemicals (ASX: ATC) received an invitation letter from the state government of Saxony, Germany, proposing the company considers the construction of a second high-purity alumina (HPA) plant in the state.

“As HPA is recognised as a critical component in the lithium-ion battery materials supply chain, an Altech HPA plant in Saxony would be well positioned to support the regions push to create a major electric vehicle battery industry, with a secure materials supply chain,” Altech Chemicals said in its ASX announcement.

Altech’s German advisers have discussed the invitation with Minister-President of Saxony, Michael Kretschmer.

Based on these positive initial discussions, Altech indicated it intends to undertake further evaluation, which will include research on various government grants that the company has been advised may be available in support of the establishment of a HPA plant in eastern Germany.

“Whilst the company remains focused on the close of funding and the construction of its Malaysian HPA plant, it also recognises the forecast significant deficit of HPA supply commencing in 2020 and the opportunity that this may present in terms of a second HPA plant,” the company said.

Altech cited a recent market outlook report by CRU Consulting that identified a likely HPA 4N+ supply shortfall of approximately 20,000 tonnes per annum in 2021 (equivalent to around four of Altech’s 4,500tpa plants).

CRU forecast this could expand to a shortfall of some 50,000tpa by 2028.

“To this extent, the company is of the view that there is merit in commencing early stage planning for additional future HPA plants, now,” Altech continued.

“Considering the invitation letter from the Saxony state government and the strong signals from the European Union on its desire to foster a rapid transition to electric vehicles, and to establish a fully integrated materials supply chain to underpin the transition, the company’s current strategic thinking is for its next HPA plant to be located in Europe.”

Healthy Mix of Resources and Oil & Gas Companies Travelling to Gold Coast Investment Showcase

THE CONFERENCE CALLER: With the 2019 Gold Coast Investment Showcase closing fast, The Resources Roadhouse continues its look at companies that will be in attendance.

Altech Chemicals (ASX: ATC) has Stage 1 construction at the company’s high purity alumina (HPA) project site in Johor, Malaysia, progressing well.

The company has completed advanced design and engineering that has allowed permits and approvals to be issued.

The site development order was approved allowing site works to commence and activities at site have transitioned from the establishment phase well into the construction phase.

Initial site establishment activities are completed, with the site fully fenced and secured.

Other work has included the completion of a site construction office, a security post, a vehicle wash down bay with sediment control, a site weather monitoring station, and temporary ablutions have been installed.

As far as actual mining goes, removal of topsoil from the site, bulk earthworks and site levelling has been undertaken with soil compaction in most areas close to being finalised.

A foundation piling rig established the foundation piling for the workshop building and the concrete footings for this building are also nearing completion.

The first steel was recently raised in plant construction anger, representing the culmination of the above-mentioned series of achievements at the project over the last six months.

Winchester Energy (ASX: WEL) is set to spud a step-out well in July at the company’s Mustang prospect, located in the Permian Basin of Texas, USA.

Winchester Energy explained the step-out well is to spud 420 metres from the previous Mustang Prospect well White Hat 20#3, which returned initial production (IP) of 306 barrels of oil per day (bopd) and continues to produce consistently.

The new well, White Hat 20#4, is a development well on the newly discovered Mustang Oil Field and is designed as a low risk well which, if successful, will further increase Winchester’s net oil production.

Winchester is planning a drilling program to develop the central lobe of the Mustang prospect that will include approximately 15 well locations.

The Mustang prospect has a Prospective Resource target best estimate P50 of 1.43 million bbls recoverable and a high estimate P10 of 3.76 million bbls recoverable from the Strawn Sand.

“The impending spud of White Hat 20#4 builds on the success of the White Hat 20#3 which returned exceptional flow rates of 306 barrels of oil per day,” Winchester Energy managing director Neville Henry said in the company’s announcement to the Australian Securities Exchange.

“White Hat 20#4 represents a low risk opportunity to further increase oil production and also increased confidence in the newly discovered Mustang Oil Field.

“We hope to extend the play further to the north and south and expect a series of large basin-floor sand lobes to occur within the Mustang area.

“The company intends to execute its Mustang development plan which focusses on relatively low risk locations initially stepping out from White Hat 20#3.

“This should see Winchester steadily expand its oil production and cash flow and with the El Dorado and Spitfire prospects representing yet more genuine upside for the company.”

King Island Scheelite (ASX: KIS) released results of an updated Feasibility Study and Revised Mineral Reserve Estimate for the redevelopment of the company’s 100 per cent-owned Dolphin tungsten project in King Island, Tasmania.

The probable reserves, in accordance with JORC 2012 code, have estimated to be 3 million tonnes at 0.73 per cent tungsten oxide WO3 (Cut‐off 0.2%).

King Island Scheelite reported the study outlined the Dolphin Open‐cut project is planned to mine and process approximately 400,000 tonnes per annum of ore for eight years to produce approximately 3,500 tonnes of tungsten concentrate per year.

This concentrate will be sold into a market the company expects to be of growing demand and constrained supply.

The Dolphin processing plant has been substantially modified since a Reserve Estimation carried out in 2015.

Processing will now be conducted through, primarily, a gravity circuit followed by a small flotation circuit to which some of the gravity tails will report.

The company has carried out further site infrastructure engineering works, resulting in capital and operating cost savings from the previous estimation.

King Island indicated its relatively advanced engineering studies and proposed methodology based on a modular design, has allowed its engineering consultants to determine that detailed design, procurement, construction and commissioning could be achieved within a fifteen‐month period after financial close.

The company is confident that once financial close has been reached, commissioning of the mine and processing plant can be achieved within the stated fifteen month period, meaning that should financial close can be achieved in the second half of 2019 then first shipment of product could be achieved in the first quarter of 2021.

“Having recently secured the first of a number of multi‐year offtake agreements, together with the flexibility in the operating site and supportive local community, we now look forward to achieving frequent operational milestones as we proceed to tungsten production, anticipated in 2021,” King Island Scheelite chairman Johann Jacobs said in the company’s announcement to the Australian Securities Exchange.

“The King Island Scheelite team has actively progressed and de‐risked the 100 per cent-owned Dolphin tungsten project, both technically and commercially.

“As part of this process, we commissioned independent consultants to provide inputs into a financial model to prepare scenario analysis to assist in interpreting the net present value ranges, potential returns and expected payback period, associated with the Dolphin open‐cut project.

“The impressive indicative economics reiterate that we have chosen to develop the right project with the right commodity in the right place and time.”
