Abstract

A secondary battery structure includes a first electrode structure including a plurality of first electrode elements spaced apart from each other and disposed in a form of an array, a second electrode structure spaced apart from the first electrode structure and including a second electrode element, and an electrolyte which allows ions to move between the first electrode structure and second electrode structure, where the first electrode structure and the second electrode structure define a cathode and an anode, and the number of the first electrode elements and the number of the second electrode element are different from each other.

First claim

What is claimed is:

1. A single battery structure comprising:
a substrate;
a plurality of first electrode elements disposed on the substrate and spaced apart from each other;
a second electrode element disposed on the substrate and spaced apart from the plurality of first electrode elements when viewed from a plan view in a thickness direction of the substrate;
a plurality of first electrode terminals connected to the plurality of first electrode elements, respectively; and
a second electrode terminal connected to the second electrode element,
wherein one of the first electrode terminals and the second electrode terminal is a cathode terminal, and the other of the first electrode terminals and the second electrode terminal is an anode terminal.

2. The single battery structure of claim 1 , wherein
the number of the second electrode element and the number of the first electrode elements are different from each other.

3. The single battery structure of claim 1 , wherein the plurality of first electrode elements is electrochemically and parallelly connected to the second electrode element via an electrolyte.

4. The single battery structure of claim 1 , wherein the single battery structure is a secondary battery structure.

5. A battery system comprising:
the single battery structure of claim 1 ; and
a battery management system connected to the single battery structure.

6. The battery system of claim 5 , wherein the battery management system comprises:
a first switching circuit unit connected to the plurality of first electrode terminals;
a second switching circuit unit connected to the second electrode terminal; and
a battery management controller connected to the first and second switching circuit units, wherein the battery management controller controls operations of the first and second switching circuit units.
