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.
Claims25
A carbon-comprising composite particle for use in Li-ion anodes comprising:
- (i) porous carbon derived from fruit,
- (ii) conversion or alloying-type active material infiltrated into one or more pores of the porous carbon,
- wherein the conversion or alloying-type active material comprises from about 40 wt. % to about 85 wt. % of the carbon-comprising composite particle.
