1. A method for disassembling a battery system, the method comprising:
preparing the battery system for treatment, wherein the battery system comprises a first adhesive that bonds a first plurality of members, and a second adhesive that bonds a second plurality of members;
submerging the battery system in a bath of a dielectric mixture to at least partially break the first adhesive and the second adhesive;
allowing the dielectric mixture to penetrate the first adhesive and the second adhesive to reach a penetration threshold;
in response to the dielectric mixture penetration exceeding the penetration threshold, removing the battery system from the bath of the dielectric mixture; and
disassembling the first plurality of members and the second plurality of members.
