Coated electroactive materials

A process comprising:

• suspending an electroactive material in a solvent selected from the group consisting of an alcohol, ether, ester, ketone, aromatic, heterocyclic, or a mixture of any two or more thereof;
• dissolving a carbon precursor in the solvent;
• and
• depositing the carbon precursor on the electroactive material to form a carbon-coated electroactive material, wherein the carbon coating is present from about 0.001 wt % to about 55 wt % based on the weight of the electroactive material;
• wherein:
• the electroactive material is a positive electroactive material or a negative electroactive material;
• the positive electroactive is selected from the group consisting of a spinel, a olivine, LiFePO4, LiMnPO4, LiCoPO4, LiNiPO4, LiCoO2, LiNiO2, LiNi1−xCoyMetzO2, LiMn0.5Ni0.5O2, LiMn0.3Co0.3Ni0.3O2, LiMn2O4, LiFeO2, LiMet0.5Mn1.5O4, LiMet0.5Mn1O4, Li1+x′NiαMnβCoγMet′δO2−zFz′, An′B2(XO4)3, vanadium oxide, and a mixture of any two or more thereof;
• wherein:
• Met is Al, Mg, Ti, B, Ga, Si, Mn, or Co;
• Met′ is Mg, Zn, Al, Ga, B, Zr, or Ti;
• A is Li, Ag, Cu, Na, Mn, Fe, Co, Ni, Cu, or Zn;
• B is Ti, V, Cr, Fe, or Zr;
