Latest Patents
One of Kai Yan's latest patents is for "Stabilized, prelithiated silicon oxide particles for lithium ion battery anodes." This innovation addresses the common issue of capacity loss during the initial cycles of battery use. Silicon-oxide based particles are known for their stable capacity and high cycling efficiency. However, they often suffer from significant capacity loss in the early stages. The introduction of lithium silicate aims to mitigate this loss, although producing such anodes has proven challenging. During the manufacturing process, exposure to water can lead to the dissolution of lithium silicate, increasing the pH and etching the silicon, which degrades the anode material. To counteract this degradation, methods such as doping lithium silicate with multivalent elements or converting some silicon to metal silicide have been developed. These approaches enhance the stability and capacity of the anodes, ultimately increasing the effective energy density of the batteries.
