1. Remove your 18650 lithium-ion battery after all use and treat it with temperature. The battery will greatly shorten the use time when the temperature is unstable, because the battery has no power and a considerable part of the lithium-ion already has memory. Use this method to release part of the memory power after it is powered on. When winter comes, put it outside for a while and then bring it inside again.
Low temperature and high energy density 18650 3350mAh-40℃ 0.5C discharge capacity ≥60%
Charging temperature: 0~45℃ Discharge temperature: -40~+55℃ Specific energy: 240Wh/kg -40℃ Discharge capacity retention rate: 0.5C Discharge capacity ≥ 60%
2. There is another way to remove the battery and leave it for about a week to slowly consume the power. You must first use a machine to completely consume the power. Then charge it fully. I guess your current charging time must be very short. After charging it completely, disconnect it and charge it again. Repeat it several times. It will definitely be effective.
3. In order to fully activate the 18650 lithium-ion battery, it must be fully charged and discharged several times. The discharge circuit is composed of a resistor and a light-emitting diode, and the discharge state can be estimated through the light-emitting diode.
Lithium-ion battery processing and welding technology
From the manufacturing of lithium-ion battery cells to the assembly of battery packs, welding is a very important manufacturing process. The conductivity, strength, air tightness, metal fatigue and corrosion resistance of lithium-ion batteries are typical battery welding quality evaluation standard. Battery products that fail to meet such standards will be strictly prohibited from sale, which will be a loss for the company.
Laser is used as the welding heat source to weld lithium-ion batteries. An automated welding production line is composed of a welding workbench, precision fixture, automatic loading mechanism and unloading mechanism. It saves labor costs and prevents manual misoperation, and the yield rate reaches more than 98%.
