AI Technical Summary

Technical Problem

The flow channel design of traditional seawater batteries is unreasonable, resulting in a slow rate at which seawater fills the electrode area, failing to quickly cover the entire reaction cross section and affecting activation speed and performance.

Method used

The design employs a tubular electrode holder with an exhaust port and an auxiliary liquid inlet. The exhaust port removes internal air, while the auxiliary liquid inlet guides seawater to be evenly distributed. Combined with positioning plates, the battery body is fixed to ensure that the electrolyte quickly contacts the electrodes.

Benefits of technology

It accelerates the battery activation process, improves the activation speed and energy conversion efficiency of the battery, extends its service life, and enhances the stability and safety of the battery.

Abstract

The invention relates to the technical field of seawater batteries, in particular to a cell structure for a rapid water-activated battery, which comprises: an electrode holder which is tubular, one end of the electrode holder is provided with an exhaust hole, and the other end of the electrode holder is provided with an auxiliary liquid inlet groove; the battery body is wound on the outer surface of the electrode holder, and an anode lead-out wire and a cathode lead-out wire of the battery body penetrate through the exhaust holes; and the positioning sheet is mounted on the electrode holder and is used for fixing the battery body on the electrode holder in the inner cavity of the shell of the water activated battery, so that the battery body is prevented from moving or being extruded in the inner cavity of the shell of the water activated battery. According to the scheme, the problems that in the activation process of a traditional seawater battery, an internal flow channel of the battery is unreasonable in design, when electrolyte (such as seawater) enters, air is compressed, the electrolyte is prevented from rapidly making contact with an electrode, and activation is slow are solved.
