(1) Stable charging and discharging performance 26650 lithium-ion battery has no memory effect, does not decompose in case of heat, high safety performance and long service life

(2) High voltage: The voltage of 26650 lithium-ion battery is generally more than 3.6 V and 3.7 V, much higher than that of nickel chromium and nickel hydrogen batteries

(3) High energy density and low self discharge rate. The capacity of 26650 lithium-ion battery is 1.5-2 times that of NiMH battery of the same quality. At the same time, the internal resistance of domestic 26,650 lithium-ion battery is less than 60m, which greatly reduces the self power consumption of the battery and extends the service life of the battery at the same time

(4) The 18650 lithium ion battery pack 5 can be used in series or in parallel. The charging and discharging principle and process of 26,650 Li ion battery, which is environment-friendly and pollution-free, are introduced. The 26650 lithium-ion battery can be charged and discharged because of the movement of active lithium ions on its positive electrode. That is, when the battery is charged, living lithium ions are produced on the positive pole of the lithium ion battery, and move to the negative pole and embedded in the layered structure of the negative pole. The cathode material system is graphite, which is carbon with layered structure. It has many micropores. When lithium ions move to the negative electrode, they will be embedded in the micropores. The more lithium ions embedded in the micropores, the higher the charging capacity.
