Long-term storage methods for lithium batteries and storage requirements for lithium iron phosphate batteries

Apr , 20 2024

What impact will the lithium battery have after being put aside for a long time? When the lithium battery is idle, due to the nature of the battery itself, self-discharge, passivation of positive and negative electrode materials, electrolyte decomposition and other phenomena will occur. The instability of the negative SEI will lead to the rapid decline of the negative active substance, which is ea...

What is the impact of low temperature on lithium batteries and solutions

Apr , 20 2024

The use of lithium batteries in low battery temperature environments is limited. In addition to a severe drop in discharge capacity, lithium batteries cannot be charged when the battery temperature is low. When the battery is charged at low temperature, the lithium ion embedment on the battery graphite electrode and the lithium plating reaction exist simultaneously and compete with each other. Und...
