Energy storage device and method of assembly of an energy storage device

A method of assembling an energy storage device, the method comprising:

• providing a housing which defines an internal space;
• disposing a first electrode into the internal space of the housing;
• disposing an electrolyte-impermeable-barrier-member, which comprises a base portion and at least one side wall extending from the base portion of the electrolyte-impermeable-barrier-member forming a receptacle structure, into the internal space of the housing in a manner so as to partition the internal space of the housing into a receptacle space bound by the electrolyte-impermeable-barrier-member and an intervening space between the housing and the electrolyte-impermeable-barrier-member, wherein the first electrode is in the intervening space between the housing and the electrolyte-impermeable-barrier-member;
• disposing a second electrode in the receptacle space within the electrolyte-impermeable-barrier-member and
• disposing an electrolyte with respect to the electrolyte-impermeable-barrier-member in a manner so as to shield the electrolyte from direct contact with the housing, wherein the electrolyte interacts with the second electrode within the receptacle space of the electrolyte-impermeable-barrier-member and reaches through at least one through-hole of the receptacle structure of the electrolyte-impermeable-barrier-member to interact with the first electrode within the intervening space between the housing and the electrolyte-impermeable-barrier-member, wherein the at least one through-hole serves as a channel connecting the receptacle space of the electrolyte-impermeable-barrier-member and the intervening space between the housing and the electrolyte-impermeable-barrier-member.
