On the Gas Evolving Characteristics of Submarine Battery in the Float-charging Process

采用理论分析和实验方法分析潜艇蓄电池在无温度补偿的浮充工况下的析氢和析氧过程,结合Arrhenius化学反应速率公式,对析氢速率、析氧速率随温度变化的规律进行指数拟合分析,发现在无温度补偿(冷却或加热)条件下,新、旧潜艇铅酸蓄电池在浮充工况时,蓄电池电解液温度都将迅速上升,并在一定时间后趋于稳定值。与旧蓄电池相比,新蓄电池温度上升速率比旧蓄电池快,析气速率与温度的关系无法满足阿累尼乌斯反应速率公式。

By theoretical analysis and experimental methods, the principles of the hydrogen and oxygen evolving rate varying with time and temperature in the float-charging process of submarine batteries with no temperature compensation were analyzed. Combining with the Arrhenius chemical reaction rate formula, this paper also made an exponential fit analysis to the rate of oxy- gen and hydrogen evolving rate against temperature. It was found that when the new and old lead-acid battery were in the process of float charging, battery electrolyte temperature will rise rapidly, and after a certain time stabilize to a constant. Compared with the old battery, the new battery temperature rise rate is faster than the old battery. The relationship between gas evolving rate and electrolyte temperature of the new battery does not fit with the Arrhenius reaction rate equation.
