LITHIUM REPLENISHMENT FOR CONTAINING CAPACITY LOSS IN LI ION BATTERIES

摘要

A lithium-ion battery includes a housing, an electrode assembly within the housing, and a high capacity regenerating electrode. The high capacity regenerating electrode is within the housing and electrically isolated from the electrode assembly. The high capacity regenerating electrode is also spaced away from and only corresponds to a single face of the electrode assembly. The high capacity regenerating electrode is configured to be selectively electrically connected to the electrode assembly to provide lithium ions to increase capacity of the electrode assembly.
