Abstract
Composites on the base of graphene, lithium phosphate and lithium titanate may serve as a suitable material for electrodes of chemical power sources. For such electrodes total capacity depends on quantum capacitance that reflects to change of charge with the shift of Fermi level. This works suggests new method for calculation fo quantum capacitance that takes into account number of lithium atoms during charge/discharge process. Varying the types of packing the most effective electrode material on the base graphene, lithium phosphate and lithium titanate is found.
