This new self-optimization process addresses a key problem in lithium ion batteries associated with retaining full charge capacity through multiple charges – reduction of electrode volume change during charging and discharging of the battery. By reducing volume change of anode materials from 400% to less than 1%, with full charge and discharge cycles, long-term cyclability is achieved. To enable this technology, a cost-effective process can be integrated into production lines for mass production. It is a self-optimization process for preparing ion battery electrodes that significantly reduces the volume change of silicon (Si) anode materials during full charging and discharging cycles. The self-optimization process and coating can be applied to any anode and cathode active materials showing high volume change during charging and discharging.
