Abstract:
1. A battery comprising: a first portion of a first substrate over which a first current collector and an anode electrode are formed; a second portion of a second substrate over which a second current collector and a cathode electrode are formed, the second substrate being different from the first substrate; and a separator placed between the first portion and the second portion to separate the anode electrode from the cathode electrode, wherein the first and second portions are joined by bonding the first and second substrates to face each other with respect to the separator, wherein the first substrate is a unitary body and a first cavity is formed in the unitary body of the first substrate, and the second substrate is a unitary body and a second cavity is formed in the unitary body of the second substrate, and wherein the first current collector and the anode electrode are disposed in the first cavity, and the second current collector and the cathode electrode are disposed in the second cavity.
