4/3/2024 0 Comments Quadro edge blendingThis IP is a barrier to any junior graphite companies that want to develop cSPG for the EV market. cSPG prices charged by these companies are US$8,000-$12,000 per tonne which reflects the cost and complexity of the process and the value of their IP. Also, at some point the Chinese will develop or “borrow” the technology to blend and will switch from using mainly synthetic graphite in EV batteries to using a blend. However, Si experiences very large volume changes on charge/discharge which breaks down the anode faster, particularly with synthetic graphite, severely limiting the amount that can be used). (advanced EV batteries are being doped with small amounts of Si which has a much higher storage capacity than graphite. The recipes are a closely guarded secret but it is generally believed that their EV batteries are 40 to 60% natural graphite and that the ratio will increase because natural graphite is cheaper, higher capacity and works better with Si. Three companies (LG, Hitachi and Samsung, and its partner BTR) have developed the technology to control expansion and extend the cycle life of natural cSPG using these processes and the result is longer life, high capacity EV batteries.
