Store the electrolyte circulation means of electrolyte.Battery body includes housing and is arranged in housing and housing is separated into positive pole
Region and the membrane module of negative regions.Lithium salts nonaqueous electrolytic solution is provided with housing.It is provided with positive pole zone anti-for chlorine
The positive plate answered.Negative plate is provided with negative regions.Positive pole zone is connected with chlorine EGR.Negative regions and electrolyte
EGR is connected.
The present invention proposes a kind of chlorine lithium battery energy storage battery method, and it includes：By TRT be connected with chlorine lithium battery and to
Input electrolyte in chlorine lithium battery, the chlorine of generation is collected in case in recycling.
Beneficial effects of the present invention are：This chlorine lithium battery belongs to large-scale electric storage device, is mainly used in intermittent electric power device
Electric energy storage device or power station.With simple structure and it is easily fabricated the features such as.The positive pole zone of chlorine lithium battery circulates dress with chlorine
Material connection, negative regions connect with electrolyte circulation means so that chlorine lithium battery stores the chlorine that is produced during electric energy can be via
Chlorine EGR collect and in case in chlorine lithium battery export electric energy when recycle, while so that chlorine lithium battery export electric energy
When the electrolyte that produces collected via electrolyte circulation means and in case recycled when chlorine lithium battery stores electric energy.This chlorine lithium
Battery coordinates intermittent discovery device to use, and can either realize the stable energy storage of extensive intermittent electric power device, additionally it is possible to carry
Economic power system high, safety and reliability, meet the national utilization of new energy resources advocated energetically at present and development, with significant
Economic benefit and social benefit.
