What research is available on replacing conventional graphite in lithium-ion batteries with silicon oxycarbide?

The Defense Systems Information Analysis Center was asked to identify organizations and publications performing research in using amorphous silicon oxycarbide (SiOC) to replace conventional graphite in lithium-ion batteries (LIBs). Graphite is commonly used as a material for anodes in LIBs because of its fast-charging properties, high specific energy densities, and long life cycles. However, concerns about graphite’s rate performance and low conductivity have spurred research…
