Claims11
Method of significantly prolonging the cycle life of rechargeable lithium batteries comprising applying to the battery as a charging mode a current interrupted at intervals of 1 millisecond to 9 seconds in a frequency range of about 0.1 to Hertz, said batteries being charged to a safe voltage limit.
Method of significantly prolonging the cycle life of a rechargeable lithium-molybdenum disulfide battery comprising applying to the battery as a charging mode a current interrupted at intervals of 1 millisecond to 9 seconds in a frequency range of about 0.1 to about 10 Hertz wherein the interrupted current charging mode is superimposed on a DC current.
Method of significantly prolonging the cycle life of a rechargeable lithium-titanium disulfide battery comprising applying to the battery as a charging mode a current interrupted at intervals of 1 millisecond to 9 seconds in a frequency range of about 0.1 to about 10 Hertz wherein the interrupted current charging mode is superimposed on a DC current.
