Silicon in Graphite Anodes for Higher Energy Density Batteries

This Altech Chemicals profile is part of a paid investor education campaign.*



Reaching carbon neutrality by 2050 requires energy generation and energy storage advancements. Tesla, at its Battery Day in 2020, discussed several enhancements that will improve the automaker’s line of electric vehicles by creating greater storage capacity and lowering manufacturing costs. One fundamental improvement involves coating battery anodes with silicon to improve storage capacity and extend batteries’ lifespan. Silicon anode batteries are believed to be the next generation of lithium-ion batteries, with a worldwide market forecast to reach US$245.9 million by 2027, growing at a CAGR of 36.5 percent.

Critical challenges prevent the widespread adoption of silicon anode batteries. One such challenge is the delithiation of the battery during its first charge cycle caused by the silicon absorbing the battery’s lithium. Additionally, finding a cost-effective solution to the delithiation problem further complicates the issue. However, Tesla’s recent acquisition of a silicon anode startup validates that this technology is crucial for future batteries. So, how can silicon anode batteries become cost-effective to improve renewable energy storage further?

Altech Chemicals (ASX:ATC, FRA:A3Y) is a research, development and commercialisation company at the cutting edge of producing revolutionary battery materials to advance clean energy electric vehicle battery storage. Altech’s patented high-purity alumina (HPA) coating process for silicon and graphite has “cracked the silicon barrier” by solving the first-charge problem and other challenges that have hindered other companies’ attempts. As a result, Altech Chemicals has produced batteries that have a 30 percent higher energy density than current lithium-ion batteries, which means improved energy storage and a longer battery lifespan.

Altech Chemicals - Graphite Particle

In a recent interview, Managing Director Iggy Tan stated “There are a couple of barriers: silicon expands 300 percent in volume, fractures and has a substantial first-cycle loss due to grabbing the lithium. A lot of companies are trying to solve this problem. Essentially, we use high-purity alumina coating technology to resolve that silicon problem.”

Altech Chemicals has already purchased land in Germany for its pilot plant to manufacture commercial samples of its patented Silumina AnodesTM product to introduce to the European market as part of the qualification process. In addition, the Company has completed a pre-feasibility study to construct a facility capable of manufacturing 10,000 tonnes per annum (TPA) of Silumina AnodesTM battery material. The pre-feasibility study indicated robust economics including an NPV of US$507M and a favorable internal rate of return of 40 percent, with a low capital cost of just US$95M.
