Latest Patents

One of Hongduan Huang's latest patents is titled "Stabilized, prelithiated silicon oxide particles for lithium ion battery anodes." This innovation tackles the issue of capacity loss that silicon-oxide based particles experience during the first battery cycles. The addition of lithium silicate is proposed to mitigate this initial capacity loss, although producing such anodes has proven challenging. During the manufacturing process, cell components are exposed to water, which can dissolve lithium silicate, leading to an increase in pH that etches silicon and degrades the anode material. Huang's methods involve doping lithium silicate with multivalent elements or converting some silicon to metal silicide before water processing. These approaches enhance the stability and capacity of the anode materials, ultimately increasing the effective energy density of the batteries.
