Title: Zinc-halogen secondary battery
Inventor: HASHIMOTO TAKASHI
IPC: H01M10/44
Filed: 1982-12-15
Abstract: PURPOSE:To prevent any halogen molecule generated over the positive electrode from being diffused over the negative electrode through a diaphragm before performing self discharge on contacting with zinc deposited on the negative electrode so as to improve the current efficiency of a zinc-halogen secondary battery by moving catholyte into an anodic chamber through a porous film by adjusting the pressure of catholyte in a cathodic chamber to be larger than the pressure of anolyte in the anodic chamber. CONSTITUTION:Pressure difference is produced between an anodic chamber 2 and a cathodic chamber 3 in a unit cell 1 by adjusting the pressure of catholyte 8 in the cathodic chamber 3 to be larger than that of anolyte 7 in the anodic chamber 2, thereby moving the catholyte 8 from the cathodic chamber 3 to the anodic chamber 2 through a diaphragm 4 made of a porous film. As a result, diffusion of bromine existing in the anolyte 7 into the cathodic chamber 3 is suppressed, self discharge is restrained and current efficiency can be remarkably improved compared to the condition in which pressure difference is not given.

Abstract: PURPOSE:To prevent water from freezing, and to reduce the operating noise with a simple structure, by providing a circuit which controls the revolution of a pump from high to low by means of signals from a detector which detects the presence or absence of water in a heat exchanger and from a detector which detects the temperature in the water. CONSTITUTION:When a bimetal switch 10 is closed as the outdoor temperature goes low, at the time when there is no water in a heat exchanger and a switch 9 is open, a signal of those information is fed into a control circuit 11, which turns a transistor Q2 only ON, closing the contact point 8a of an ON-OFF relay 8. Since the contact point 7a of an ON-OFF relay 7 is at high 'B' side, a pump 6 is rotated at high to pump up water into the heat exchanger. Afterwards, when water is fully fed into the heat exchanger and the switch 9 is closed, a signal of those information is fed into the control circuit 11, which turns a transistor Q1 ON. Then the contact point 7a of an ON-OFF relay 7 is closed at the low 'A' side, which makes the revolution of a pump 6 low. With such an arrangement, the water in the heat exchanger and in the water feed pipe can be prevented from freezing, and at the same time the operating noise from the pump can be reduced.
