  • Altech Chemicals (ATC) has signed a collaboration agreement with leading silicon producer Silicon Ferrosolar
  • The companies will work together to develop a high capacity, long cycle life silicon active material for use in lithium-ion batteries 
  • Altech is currently developing a coating technology which improves the performance, longevity and safety of batteries
  • The agreement will run for one year and if any party chooses to terminate 30 days notice must be given
  • Altech also launched a $14.5 million entitlement offer
  • Shareholders will receive two new shares for every five held, as well as one free attaching option for every two new shares subscribed for
  • The money will be used for Altech's European initiative, payments for stage two work, development activities, working capital, and corporate costs

Altech Chemicals (ASX:ATC) has signed a collaboration agreement with leading silicon producer Silicon Ferrosolar. 


This agreement will see both companies work together to develop a high capacity, long cycle life silicon active material for lithium-ion (li-ion) batteries. 


Silicon Ferrosolar has the technology to produce high purity silicon and is developing tailor-made silicon powders for li-ion battery anodes. 


Under the agreement, Altech could potentially use its high purity alumina (HPA) and coating technology to coat particles designed by Silicon Ferrosolar. 


Altech is currently developing Anode Grade HPA and coating technology to apply to particles used in li-ion batteries. This coating improves the performance, longevity and safety of batteries. 


Additionally, Altech will fund the testwork and supply the coating technology. 


The agreement will run for one year and if any party chooses to terminate, 30 days notice must be given. 


Entitlement offer 

Altech also launched a $14.5 million partially underwritten non-renounceable pro-rata entitlement offer. 


Shareholders will receive two new shares for every five held as well as one free attaching option for every two new shares subscribed for. 


The shares will be priced at 4 cents each, which represents an 18 per cent discount to Altech's closing price on November 5 of 4.9 cents, and a 15 per cent discount to the five-day volume-weighted average price. 


Further, the options are exercisable at 8 cents with expiry on May 31, 2022. 


Altech's major shareholders, Deutsche Balaton and Delphi and Melewar, have agreed to subscribe to 52 per cent of the offer, $7.6 million.

 

The money will be used for Altech's European initiative, as well as to cover payments for stage two work, development activities, working capital, and corporate costs.

HPA RESEARCHING

GERMAN RESEARCH CONFIRMS 4N HPA CRITICAL FOR LITHIUM-ION BATTERY SAFETY & PERFORMANCE

ASX Announcement 26 May 2020 


Highlights 

  • Test work shows sodium contamination from low grade alumina and boehmite in lithium-ion battery applications 
  • Up to 80-fold increase of sodium levels 
  • Minimum sodium leaching for 4N alumina (99.99%) 
  • Serious battery safety risks, performance and durability problems 
  • Minimum quality industry standards for alumina coated separators called for


Altech Chemicals Limited (Altech/the Company) (ASX: ATC) (FRA: A3Y) is pleased to provide the results from high purity alumina (HPA) research activities recently completed by the internationally renowned FraunhoferGesellschaft research organisation (refer ASX Announcement 25 March 2020). 


The Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) of Dresden, Germany specialises in lithium-ion battery research. The Altech commissioned test work focussed on assessing how readily impurities (predominantly sodium) leach from lower quality alumina (sub-4N) and boehmite into battery electrolyte solution, a cause of lithium-ion battery thermal runaway, inefficiency and life cycle reduction.


As the lithium-ion battery industry rapidly expands in response to increased demand for electric vehicle (EV) and portable electronic device batteries, some in the industry have turned to cheaper low-grade alumina and boehmite as a coating material for battery separators. This substitution is away from high quality 4N alumina (99.99%) as a standard separator sheet coating. Results from the Fraunhofer test work point to a previously unrecognised contamination risk and heightened safety hazard – sodium leaching – from lower grade alumina or boehmite.


A lithium-ion battery stores then releases power by lithium ions moving between the battery cathode and anode, representing the charge and visa-versa discharge cycles. Separating the cathode and anode within the battery is a thin polymer sheet through which lithium ions pass via a liquid electrolyte – a separator sheet (see Figure 1). The composition of these polymer separator sheets has evolved over time in parallel with increases in battery energy density and faster charging / discharging requirements. Now separator sheets are mostly coated with thin layers of alumina powder to maintain separator integrity under the ever-increasing operating temperatures of modern high-energy lithium-ion batteries (see Figure 2). 



The Fraunhofer test work exposed various commercial grade alumina / boehmite powders known to have been adopted for battery separator coatings, to lithium battery electrolyte solution under controlled battery type conditions. What was observed was severe sodium leaching and contamination of the organic electrolyte solution from the lower grade alumina and boehmite powders. The IKTS reported that the sodium content in the electrolyte rose from an initially acceptable 0.5 ppm, up to potentially catastrophic level of 40 ppm (an 80-fold increase) for the test using low quality 3N alumina (99.9%). Similar leaching and electrolyte contamination were observed for the boehmite test (99.7% purity), where the sodium level in the electrolyte jumped 20-fold. For the 4N alumina (99.99%), almost zero leaching of sodium was observed.


Figure 3 illustrates the discolouration of the organic electrolyte solution that resulted from the leaching of contaminates in the Fraunhofer test work.

HPA PLANT SITE CONSTRUCTION

JOHOR HPA PLANT SITE CONSTRUCTION ACTIVITIES RECOMMENCE 

ASX Announcement 3 June 2020 


Highlights 

  • Stage 2 HPA plant construction work has recommenced 
  • COVID-19 Standard Operating Procedures implemented 
  • Electrical substation construction expected to be completed during July 2020


Altech Chemicals Limited (Altech/the Company) (ASX: ATC) (FRA: A3Y) is pleased to provide an update on the status of activities at the Company’s high purity alumina (HPA) site in Johor Bahru, Malaysia, where construction activities have now recommenced.


In response to the global outbreak of the COVID-19 pandemic, the Malaysian government imposed a Movement Control Order (MCO) effective 18 March 2020, for an initial period of one month. The MCO resulted in the closure of all non-essential government and private business premises, and consequently the suspension of all construction works and closure of Altech’s HPA plant site at Tanjung Langsat. Subsequently, the MCO was extended on four occasions and is currently in effect until 9 June 2020.


However, the Malaysian government recently announced a relaxation of MCO restrictions under a revised Conditional Movement Control Order (CMCO). The CMCO provides for the recommencement of business activities, such as construction, but only if pre-approval is obtained from the Ministry of International Trade and Industry (MITI). A key condition of the recommencement of activities is a requirement to implement Standard Operating Procedures that follow the Malaysian Ministry of Health guidelines for COVID-19.


Altech has now received the MITI approval for business recommencement and has implemented the required COVID-19 related workplace standards for personal and workplace hygiene, including individual screening (COVID-19 testing) and social distancing. COVID-19 testing for all personal was completed last week, and final site inspection by the Construction Industry Development Board for verification of implementation of the new procedures has been conducted; this has allowed for the recommencement of construction activities at site. 



Prior to the suspension of construction activities in March 2020, work on the electrical substation was nearing completion, with only cosmetic architectural detailing and internal fit out of some mechanical and electrical systems remaining. It is expected that these outstanding works will now be completed by July 2020, followed by rectification of any punch list items and a final handover inspection of the substation to Altech.
