Australia Altech company develops high-capacity, long-life silicon-based lithium battery

According to foreign media reports, Australia’s Altech Chemicals recently stated that it plans to establish a joint venture to enter the booming electric vehicle market. The company will develop a silicon-based battery that is praised by Tesla as high-capacity and long-life, and claims that this battery may replace existing lithium batteries. Perth-based Altech is a supplier that can process 99.9% high-purity alumina. Alumina has a wide range of uses, and lithium battery manufacturers can use alumina to improve the performance, life and safety of battery products. Altech recently stated that it has signed a cooperation agreement with Spanish silicon processor SilicoFerrosolar. The company is committed to developing special high-grade silicon powder for processing lithium battery anodes. As Altech pointed out, at the BatteryDay event recently hosted by the American electric vehicle and battery energy storage giant Tesla, founded by Elon Musk, the application of silicon battery solutions has become an industry player Hot topics discussed. At this highly anticipated event, Tesla predicted that lithium batteries with silicon anode technology will dominate the battery market in the next five to seven years, and announced plans to use silicon anode technology as part of its goal of processing lithium batteries. Silicon is used in lithium batteries because its capacity (in theory) is 10 times that of carbon-based lithium batteries, and silicon is one of the most abundant materials on earth. But its adoption also encountered some obstacles. It can be attributed to three important problems: poor charge-discharge cycle performance, instability caused by the mutual use of silicon surface and electrolyte, and low initial discharge efficiency (CE) (that is, the large loss of initial charge and discharge capacity of the battery ). Altech said that the aluminum oxide coating on the silicon anode may solve the three problems of silicon materials used in lithium batteries. The company said in a statement: 'The combination of the capabilities and technologies of the two companies provides the industry with great development potential and interesting solutions.' Altech said, SilicoFerrosolar is an industry-leading silicon processor. , Has the mature ability to use advanced technology to promote innovation to create new solutions and applications, and is specifically developing and processing special silicon powder for silicon anodes of lithium batteries. Silicon Anode has developed high-purity aluminum oxide and coating technology for battery anodes, with the goal of applying the coating on the typical graphite particles commonly used in lithium battery anodes. Both companies stated that they believe that this technology can be applied to silicon anodes for lithium batteries from SilicoFerrosolar. According to the cooperation agreement, the two companies will analyze and study the possibility of coating silicon particles supplied by SilicoFerrosolar with high-purity alumina with silicon anodes. Altech will supply the coating technology as the sole funder of the testing work. Altech also recently launched a $14.5 million financing. The company’s major shareholder, German investor Deutsche Balaton and Malaysian processor Melewar Industrial Group, have agreed to accept an approximately 52% rights issue, which will be completed in early December.
