A fast charge system 20 including a fast charge composite 60 and a secondary battery 22 enables the secondary battery 22 to be charged in less time than is possible with traditional charging means. The fast charge composite 60 includes a separator 62 of cellulose wetted with a second electrolyte 64 that contains third ions 94 having a positive charge and fourth ions 96 having a negative charge and contacting the adjacent electrode 32, 46 of the secondary battery 22. A fast charge layer 30 of thermally expanded graphite is disposed adjacent and parallel to the separator 62. A second electrical power PFC, which may be greater than a maximum charging power PMAX transferred through traditional charging, is transferred as a function of a second voltage V2 applied between the fast charge layer 30 and the battery lead 34, 50 of the adjacent electrode 32, 46, which causes the third ions 94 and the fourth ions 96 to migrate through the separator 62 to cause the secondary battery 22 to become charged.
