Embodiment 1
[0029] The battery system is composed of 24 single cells in series, in which the anode of the single cell is an aluminum alloy plate with a size of 160mm×120mm×2.5mm, the size of the cathode of the single cell is 160mm×130mm×2mm, and the distance between the poles of the single cell is 2mm. The unit stores 10L of 8mol / L KOH solution and the bottom is welded to the battery system shell as a whole, with cooling fins around it, the system discharges at a constant power of 800W, the ambient temperature is 20°C, and discharges for 30min. After the system temperature is stable, test the temperature inside the single battery Distribution. The volume of the system is 107L, the weight is 86.5kg, and the power consumption is 68W.
[0030] As a comparison, the liquid storage unit in the battery system is an ordinary plastic product, and the heat exchanger is used to dissipate heat inside the system. The discharge is also performed at a constant power of 800W. After 30 minutes, the temper...

Description
technical field [0001] The invention relates to a metal / air battery system, in particular to a metal / air battery system with a liquid storage unit having a heat dissipation function. 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. Therefore, metal / air batteries have broad application prospects in many fields of mobile power sources such as communication power sources, field emergency power sources, lighting power sources, and reserve power sources. [0003] In metal / air batteries, about 50% of the energy is dissipated as heat due to internal irreversibility and chemical reaction heat generated by ohmic polarization. Fast, resulting in a reduction in the battery reaction area, and even damage to t...
