Due to the degradation of the diaphragm material, the perforation of the diaphragm material, the loosening of the active material, the use of two-pole connection, or the formation of dendrites through the diaphragm during charging causes an internal short circuit. After the deep discharge, the adsorption separator is prone to lead or dispersion. Precipitation, or formation of dendrites, resulting in micro-short-circuiting of the positive and negative plates.
Due to the redundant design of the negative electrode of the lead-acid battery , the charging efficiency of the charging in the first and middle stages is higher than that in the positive plate. Therefore, before the oxygen is deposited in the positive plate, the negative electrode has generated enough suede lead to recombine the oxygen. In the process of making a battery, the amount of the negative electrode active material is used as a control factor to alleviate the deterioration of battery performance.
In summary, the high temperature accelerates the battery water loss, thermal runaway, positive grid corrosion and deformation, low temperature will cause negative passivation failure, temperature fluctuation will accelerate internal short circuit of lead-acid battery, etc. Affects battery life.
