Forced discharge of Li-ion batteries for recycling extracts residual electrical energy from the battery cells to avoid sudden and unexpected release of residual energy during recycling. A battery cell containment device applies a physical restraint to one or more battery cells, and engages positive and negative terminals on the cells for electrical communication. A cooling medium flows through the containment for thermal transfer of excess heat generated during the discharge. Depending on the residual charge remaining in the battery cells, excess electrical energy is discharged thought the positive and negative terminals to a state of zero charge. A reverse voltage forces current through the anode to being the battery to a zero-energy state. The reverse voltage continues until internal short circuits resulting from degradation of current collectors in the battery render it benign.
