Metal/ air battery system

Abstract

The invention provides a metal / air battery system. The metal / air battery system comprises a metal / air battery pack, a liquid pump, a heat exchanger and a liquid storing unit, wherein the metal / airbattery set comprises N single batteries which are connected in series, and N is an integer not less than 2; each single battery comprises a single battery housing; a main liquid pouring channel, a main liquid draining channel and an air flowing channel are arranged between the adjacently connected single battery housings; flow rate balancing unit is arranged in each main liquid pouring channel,and the outer part of each main liquid pouring channel is connected to a motor; the motor is used for controlling the flow rate balancing units to act to realize the flowing consistency of electrolyte. With the adoption of the metal / air battery system, the electrolyte flowing consistency is high; the performances (such as voltage and temperature) of the single batteries are effectively controlled; the discharge capacity of the system is improved; the anode utilization rate is increased; the service life of a cathode in actual working conditions can be effectively prolonged; the flow rate balancing units are arranged in the main liquid pouring channel, so that the flowing consistency is reasonably improved on the premise that the size of the main flowing channels remain, as a result, the system size is reduced, and the specific energy of the system is increased.

Description

technical field [0001] The invention relates to a metal / air battery system, in particular to a metal / air battery system with high consistency. Background technique [0002] A metal / air battery is an electrochemical reaction device that uses metal (such as magnesium, aluminum, zinc, etc.) as the anode fuel, oxygen in the air as the oxidant, and lye as the electrolyte solution. my country's magnesium, aluminum, zinc and other metals are rich in reserves and low in price, so metal / air batteries have broad application prospects in many fields of mobile power sources such as communication power supplies, field emergency power supplies, lighting power supplies, and reserve power supplies. [0003] Since the working voltage of metal / air battery cells is only 1-1.5V, when encountering electrical equipment with higher rated voltage requirements, it is often necessary to connect multiple metal / air cells in series to obtain higher voltage. At the same time, due to the chemical reactio...

Problems solved by technology

However, there is a certain range for reducing the flow rate. If the flow rate is too low, the heat dissipation cannot meet the requirements; and there are certain limitations in increasing the diameter ratio of the main pipeline and the branch pipeline. The branch path should not be too thin; on the other hand, the larger the main path, the more volume it will occupy
