Influence of electrolyte on discharge performance of seawater battery and electrolyte control system

Due to the use of natural seawater, the properties of seawater have a great impact on the battery performance, such as salinity, temperature and flow rate. In order to reduce the impact, the electrolyte system needs to be controlled and optimized. This work is of great significance to the optimization of battery performance. For example, the US Navy has developed an auxiliary system electrolyte supplement management system for Al / AgO battery used in heavy torpedo.

For such batteries with long working time, one side needs to eliminate reaction products and heat, and control the concentration of alkali solution and aluminate at the same time.

After the battery works for a period of time, it starts to discharge electro-hydraulic fluid to supplement the concentration of NaOH (50%) and reduce the concentration of product aluminate. This system can improve the volume energy and energy density by 60% ~ 70%, which is also one of the characteristics of seawater battery.
