1. A battery comprising:
a plurality of interconnected battery segments defining:
a plurality of energy storage units; and
at least one flexible linkage each physically and electrically connecting respective two adjacent energy storage units,
wherein the plurality of energy storage units together define opposite first and second sides both extending along a length of the battery, and
wherein each of the at least one flexible linkage respectively extends from the first side to the second side to respectively define a first space between the flexible linkage and one of the two adjacent energy storage units along the first side and a second space between the flexible linkage and another one of the two adjacent energy storage units along the second side:
at least one buffer member, each disposed in a respective one of the first space and
an encapsulation arranged to encapsulate the plurality of interconnected battery segments,
wherein two adjacent energy storage units are movable with respect to each other via the corresponding flexible linkage in the encapsulation;
wherein the energy storage units and the at least one flexible linkage include the same multilayer structure, which comprises, at least, a first electrode, a second electrode, and a separator between the first electrode and the second electrode; and
wherein each of the energy storage units comprises a folded structure, a wound structure, or a spiral structure of the multilayer structure.
