1st  generation battery: Graphite anode material (LG Chem, Samsung SDI, SK Innovation, BYD, etc.)
2nd  generation battery: Battery using silicon/graphite composite anode material (Samsung SDI, Eurocell, etc.)
Electric vehicle battery material Roadmap
Material : SNE Research
The 1st  generation battery with 360mAh/g graphite anode material is difficult to further improve capacity.
The 2nd generation battery is a battery that uses a silicon/graphite composite anode material with silicon having a theoretical
capacity of 4200 mAh/g added to graphite, and is expected to lead the battery market in the future.
(All battery manufacturing companies such as Samsung SDI, LG Chemical, BYD, and Tesla are in development)
