Abstract
In a battery having a cathode in which a halogen is employed as an active material, the halogen is dissolved in an organic solvent such as a halogenated hydrocarbon, whereby the halogen is stored, and is utilized when needed. This battery can be applied as both a primary battery and a secondary battery. According to the battery of the present invention, a power required during the operation of the battery is reduced, whereby the total energy efficiency of the battery can be improved.
Claims16
An improved secondary battery composed of a battery comprising an anode, cathode and electrolyte tank for feeding an electrolyte to said battery and a halogen storage tank containing an organic solvent for absorbing the said halogen as a cathode active material, wherein the halogen storage tank is connected to said electrolyte tank through a gaseous phase, so that during its charging operation, the halogen gas generated from the battery is delivered into the halogen storage tank where it is stored therein by being absorbed in the organic solvent disposed therein, and during its discharging operation, the halogen gas is delivered from said halogen storage tank into said electrolyte tank where it is dissolved in the electrolyte which is to be delivered to the battery.
An improved primary battery comprising, a battery in which a halogen is used as an active material, an electrolyte tank and a halogen storage tank for storing the organic solvent wherein the gas phase of the halogen tank is connected to the gas phase of the electrolyte tank, wherein during its discharge-operation, said halogen gas is delivered from the halogen storage tank to said electrolyte tank.
