Abstract
A method of producing a lithium-ion battery includes filling at least one cell of the battery with an electrolyte followed directly with a first step of sealing the at least one cell and a second step of applying pulsating compression to the at least one cell during formation charging, the pulsating compression comprising alternating a first time period of applying a first compression force F1 greater than zero and a second time period of applying a second compression force F2, wherein F1>F2, and the formation charging includes a first charge of the battery.
Claims7
A method of producing a lithium-ion battery, comprising:
- filling at least one cell of the battery with an electrolyte followed directly by sealing the at least one cell and then applying pulsating compression to the at least one cell during formation charging, the pulsating compression comprising alternating repetitions between applying a first compression force greater than zero for a first time period and applying a second compression force lower than the first compression force for a second time period, and the formation charging including a first charge of the battery.
