CHANGING THE SELF-DISCHARGE OF ACID BATTERIES FROM TEMPERATURE AND WAYS TO REDUCE IT

Аннотация

This paper discusses a method to reduce the self-discharge process of acid car batteries. The dependence of the self- discharge of storage batteries on the ambient temperature has been studied. At the same time, it was found that an increase in the storage temperature of storage batteries from + 15°C to + 45°C accelerates the self-discharge process up to 62% within 12 months. Replacing the alloy composition of the electrode, taking into account the electronegativity of the components, reduces the self-discharge process to 2% monthly. Batteries with electrodes, where antimony is replaced by calcium in the alloy, the self-discharge process is relatively low and the consumption of the working fluid is also relatively low. These parameters allow them to be manufactured as maintenance-free power sources.
