If a lithium-ion battery has become too weak for use in a power drive after many years of operation, it usually still suits a secondary application, such as stationary operation. This concept is referred to as "second life" and is increasingly being implemented in practice. In cases where a battery is irreparably damaged due to a defect and its cells or modules are no longer usable, the battery is dismantled into its components, which are individually processed through the recycling system.
