1. A method for making composite anode material comprising:

  • milling graphite particles with carbohydrate particles to yield graphite-carbohydrate particles,milling the graphite-carbohydrate particles with anode material particles having a native oxide layer, to form a graphite-carbohydrate layer over at least part of a surface of the anode material particles, andcarbonizing the milled anode material particles to form composite anode material particles which are de-oxidized and have at least a partial composite porous carbon-graphite coating forming an at least partial porous graphite shell over the anode material particles.
