Seawater Battery: Strategies to Enable High Performance

ECS Meeting Abstracts, 2022
Renewable energy sources such as solar, wind, and tide energy have been implemented to decrease air pollution due to common fossil fuel-generated electricity [1]. However, those systems are intermittent; creating the need for an energy storage system (ESS) that stores over-generated energy for later use and effectively matches the power fluctuation ...

A New Rechargeable Seawater Desalination Battery System

Batteries and Supercaps, 2018
AbstractThe exploitation and utilization of seawater resources has become a significant research topic nowadays. In this communication, we report a rechargeable desalination battery system for the first time. This design can integrate the electrochemical battery, seawater desalination, and acid‐alkali production in one system.

Rechargeable Seawater Battery

ECS Meeting Abstracts, 2015
This study demonstrates the feasibility of a rechargeable sweater battery that use seawater and its contents of chemicals as the anode and cathode materials for the first time. Na-ions were harvested from the seawater by charging the battery, and the harvested Na-ions were discharged with water (or oxygen dissolved in the seawater) as oxidants to ...

Development of Prismatic Cells for Rechargeable Seawater Batteries

Advanced Sustainable Systems, 2022
AbstractRechargeable seawater batteries (SWBs) using seawater as a catholyte have attracted extensive attention owing to the ocean's high theoretical energy density (3051 Wh L‐1, 3145 Wh kg‐1) and excellent thermal management. However, despite many improvements in materials and cell designs used in SWBs so far, there is a limit on the energy density in

Development of a Seawater Battery for Deep-Water Applications

Journal of Power Sources, 1997
Dissolved-oxygen seawater batteries rely on the corrosion of a reactive metal anode and the reduction of oxygen at an inert cathode to generate a potential of about 1 V when immersed in seawater. Because oxygen is not very soluble in seawater, such batteries are characterized by small cathodic current densities and are therefore most suitable for long ...

Influence of organic matter on seawater battery desalination performance

Desalination, 2023
A rechargeable seawater battery desalination (SWB-D) system stores energy in a battery cell while removing salts from saline water via a sodium superionic conductor membrane and an anion exchange membrane. However, the electrochemical performance often degrades owing to the organic fouling generated on the ion exchange membranes.

Single cell seawater batteries

Proceedings of the 34th International Power Sources Symposium, 2002
The author explores the feasibility of providing watts of power for years with a single-cell approach built around aluminum anodes and oxygen-consuming or hydrogen-evolving cathodes. Instead of connecting cells together in the usual manner to form a battery, a single cell can power numerous small DC/DC power converters which together provide useful ...
