Abstract
An embodiment is directed to an electrode composition for use in an energy storage device cell. The electrode comprises composite particles, each comprising carbon that is biomass-derived and active material. The active material exhibits partial vapor pressure below around 10−13 torr at around 400 K, and an areal capacity loading of the electrode composition ranges from around 2 mAh/cm2 to around 16 mAh/cm2.
