Fast reasons for the decrease in low -temperature battery power.marine battery for trolling motor Production

　　Among the many environmental elements, temperature has the greatest effect on the performance of lithium battery. The electrolyte used for lithium batteries as organic liquids, like oil, will become thick or even condensed at low temperature. At this time, the activity of the lithium salt in the conductive electricity is greatly limited. In this way, the charging efficiency is very low, which will cause the lithium battery to charging slowly at low temperature and dissatisfaction, as well as discharge.

　　Lithium batteries are limited in low temperature environments. In addition to the severe decline of the discharge capacity, lithium batteries cannot be charged at low temperatures. When charging at low temperature, the embedded and lithium -plated response of lithium ions on the battery graphite electrode is at the same time and compete with each other. The diffusion of lithium ions in graphite under low temperature conditions is suppressed, and the conductivity of the electrolyte decreases, which makes the embedded rate decreased and the lithium plating response will be more likely to occur on the surface of the graphite. Lithium -ion batteries The main reasons for life -life during low temperatures are increased internal impedance increases and lithium ion analyzes the capacity attenuation.

　　At low temperature, the performance of lithium battery is seriously degraded, and some side reactions will occur during the charge and discharge of lithium ion batteries. These side reactions are mainly the irreversible response of lithium ion and electrolyte, which will cause the lithium battery capacity to decline, which will further deteriorate the battery performance
