Pay attention to the temperature and humidity when storing lithium batteries. It is recommended to store lithium batteries at 20 ° C to avoid humidity and power loss. Do not squeeze, collide, and do not store in places with strong static electricity and strong magnetic fields.
When charging and discharging, do not overcharge, do not use inferior chargers, and avoid using high-rate chargers. Do not discharge more than 80% of the battery capacity.
Lithium batteries are disposable batteries, lithium-ion batteries are rechargeable cycle batteries!
There are two kinds of lithium battery and lithium ion battery, lithium battery is a primary battery, can be continuous or intermittent discharge, suitable for low power consumption of electronic products. Lithium primary battery self-discharge rate is low, can be stored for 3 years, cold storage effect is better, but not rechargeable, charging is very dangerous.
Lithium-ion battery is a secondary battery, rechargeable, can be stored for more than half a year, low self-discharge rate, most of the capacity can be restored. Lithium ion batteries commonly use metal oxide of lithium alloy as the positive electrode material, graphite as the negative electrode material, and batteries using non-aqueous electrolyte solutions.
The chemical reaction equation of lithium-ion battery is LiCoO2==Li(1-x)CoO2+XLi++Xe-(electron), the chemical equation of the negative electrode is 6C+XLi++Xe-= LixC6, and the total reaction of the battery is LiCoO2+6C=Li(1-x)CoO2+LixC6.
Long-term storage of lithium batteries should be recharged every 3-6 months, charging to a voltage of 3.8-3.9V, keep at 40%-60% discharge depth is appropriate, not full. Batteries should be stored in a dry environment of 4-35 ° C or moisture-proof packaging, away from heat sources and direct sunlight. Lithium batteries have a wide range of application temperatures, but when used outdoors in the northern winter, the capacity will be reduced, and the capacity can be restored under room temperature conditions.
The above is how to use lithium batteries correctly, and complying with the use method can effectively protect lithium batteries, extend battery life, and avoid the occurrence of safety accidents.
