锌空气电池在工作时产生的热量会使电池温度升高,如果不及时散热的话,会使电解液水分蒸发加快而导致电池工作性能下降,所以研究电池产热量意义重大。本文使用一种实验测量与对流散热公式相结合的方法求得锌空气电池的产热量,并粗浅分析热量的主要来源。结果表明,室温下大电流恒流放电,产热量与输出电能之比为7:10。
The generated heat will cause the temperature rises when the zinc-air battery in the work. If not promptly cooling, it makes electrolyte evaporation of water to speed up the decline in battery performance. In order to count the heat production of the combined measurement and convection cooling formula . The results production and output electrical energy was 7 : 10 . zinc-air battery, this paper show that the ratio of heat
