1. A battery comprising:
a boost pack and a primary energy pack;
(a) wherein the primary energy pack comprises a plurality of unit cells arranged as one or more rechargeable battery stacks, each unit cell comprising:
(i) a positive electrode layer;
(ii) a lithium metal negative electrode layer;
(iii) a solid-state electrolyte layer positioned between the positive electrode layer and the negative electrode layer;
(iv) a positive current collector layer in electrical contact with the positive electrode layer; and
(v) a negative current collector layer in electrical contact with the negative electrode layer;
wherein the boost pack has a capacity of about 1-20 kWh and wherein the primary energy pack has a capacity of about 50-150 kWh;
wherein the boost pack has a power capability of about 60-200 kW peak and about 30-80 kW continuous, and wherein the primary energy pack has a power capability of about 60-300 kW peak and about 30-100 kW continuous;
(b) one or more compressible structures configured to apply pressure to the battery stacks during expansion of the one or more battery stacks during charge; and
(c) a confinement structure about the one or more stacks and the one or more compressible structures.
