Abstract:
An electricity storage device comprising:an electrolyte film which conducts electricity; a lithium graphite thin sheet directly attached to one longitudinal side of said electrolyte film, said lithium graphite thin sheet formed of a plurality of graphite particles and a plurality of lithium particles; a composite polymer thin sheet which conducts electricity directly attached to another longitudinal side of said electrolyte film; a positive collector attached to and extending along entirely a side of said composite polymer thin sheet opposite said electrolyte film, said positive collector having a bonding point extending outwardly beyond said side of said composite polymer thin sheet; a negative collector attached to and extending along entirely a side of said lithium graphite thin sheet opposite said electrolyte film, said negative collector having a bonding point extending outwardly beyond said side of said lithium graphite thin sheet; and a housing formed of an insulative material, said housing hermetically containing said negative collector and said lithium graphite thin sheet and said electrolyte film and said composite polymer thin sheet and said positive collector, said bonding point of said positive collector and said bonding point of said negative collector each extending outwardly of said housing.
