FAST-CHARGE SYSTEM (VERSIONS) AND METHOD OF CREATING A FAST-CHARGE COMPOSITE (VERSIONS)

摘要

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.
