Claim 0:
1. A container comprising:
at least one battery module, wherein the at least one battery module comprises: one or more electrochemical cells each comprising a lithium metal negative electrode or a thin film solid-state separator electrolyte, or both;
a pressure sensor and a compressible element, wherein the compressible element is a gas, liquid, or both a gas and a liquid, wherein the compressible element is configured to expand and contract; and
at least one controller;
wherein the pressure sensor and the compressible element are between an inner wall of the container and an outer wall of the one or more electrochemical cells, wherein the compressible element is in contact with both the inner wall of the container and the outer wall of at least one of the one or more electrochemical cells, and wherein:
the side of the inner wall opposite the side in contact with the compressible element is in contact with the lithium metal negative electrode or a thin film solid-state separator electrolyte;
the pressure sensor is in electrical communication with the at least one controller; and
the pressure sensor monitors pressure in the container and the compressible element is configured to maintain an isostatic pressure on the one or more electrochemical cells.
