Abstract
Conditioning secondary lithium ion cells at elevated temperatures above ambient reduces the time required to complete this process and produces cells and batteries which demonstrate improved electrochemical performance. Conditioning includes subjecting an electrochemical cell to at least one full charge/discharge cycle whereby gases generated and removed before the cell is sealed and ready for use.
