Application of nano anode technology in electric cars
The amount of energy that a lithium-ion battery can provide for an electric vehicle (EV) is limited by the amount of charge stored in its anode and cathode. Although graphite has been the preferred anode material for the past 30 years, according to reports, for silicon anode to be used in electric vehicles, its production cost must be reduced and its energy density must be increased significantly.
Silicon is an important material in anode construction, which is able to extend the working range of EV up to 20-40%. However, increasing the higher capacity comes with the technical issue of structural deterioration of these anodes, which is caused by the swelling of the silicon anode. In addition, most silicon-based anode materials suffer from processing problems using current Li-ion battery equipment and processes.
One company has overcome these problems by innovating and exploiting graphene technology, and a recent experiment confirms this claim. All high-performance silicon anode materials are produced from the toxic and dangerous silane gas by chemical vapor deposition (CVD) methods. While such methods pose many challenges and are expensive. The electric vehicle industry is looking for an alternative and safe method that Solidion Technology has succeeded in providing a suitable alternative to the current silicon anodes.
The company has developed anode materials that aim to meet the requirements of next-generation EV batteries. It should be noted that this company started the development of LI-S batteries in 2010 and has a wide range of intellectual properties, including more than 100 patents in the field of lithium-sulfur batteries. Also, this company has fundamental technologies for full commercialization of these batteries. These technologies include a protected lithium metal anode coating, a solid or quasi-solid state electrolyte and separator, a graphene cathode, and innovative designs.
