Title:

BIPOLAR BATTERY

Document Type and Number:

WIPO Patent Application WO/2017/145378

Kind Code:

A1

Abstract:

Conventional bipolar batteries are configured by assembling single batteries, each being sealed to prevent liquid junction, and prevent corrosion in a peripheral apparatus caused by the leakage of a solution. For this reason, solution injection operations are required for each of the single batteries such that an increase in the battery size requires considerable production time and costs. In addition, since wiring establishes connections among the single batteries, a wiring space is required. In this invention, a collector having a protruding portion, which is a bottom cylindrical conductor comprising a bottom portion protruding outward, is used in order to eliminate the wiring space, and decrease ohmic losses caused by the wirings. In addition, this invention has water-repellent sheets to compartmentalize electrolytic solution between cells in order to prevent the liquid junction.
