26650 lithium-ion batteries are now mainly used to replace traditional nickel-chromium and nickel-metal hydride batteries, and are used in mining lamps, flashlights, power tools, toys, instruments, rear switching power supplies, communication equipment, medical equipment and their military lighting industries. Compared with nickel-chromium and nickel-metal hydride batteries, its advantages are reflected in the following aspects:
1. High energy density and low self-discharge rate.
The capacity of the 26650 lithium battery is twice that of the nih rechargeable battery of the same quality. In addition, the internal resistance of the 26650 lithium battery in my country is less than 60m, which greatly reduces the self-consumption of the rechargeable battery and can improve the use time of the rechargeable battery.
2. Stable charge and discharge characteristics of the battery.
The 26650 lithium battery has no memory, is insoluble when heated, has a high safety factor and has a long service life.
3. High working voltage.
The working voltage of 26650 lithium battery is generally higher than that of nickel-chromium alloy and nickel-metal hydride rechargeable batteries.
4. 18650 lithium-ion battery pack can be used in series.
5. Zero pollution of environmental protection.
The Li-Ion 26650 can often be recharged, charged and discharged with specific Li-Ion battery exercises. That is, when the rechargeable battery is charged, the lithium-ion battery is converted into a specific lithium-ion battery. The negative material management system is high-purity graphite, which is a layered structure of carbon, which has many microplates, and when the lithium-ion battery moves to the negative battery, it is placed in the microplate and embedded in the microplate The more lithium-ion batteries you have, the higher the battery charge capacity.
Similarly, when charging and discharging the battery, the lithium-ion battery slides down the negative carbon layer and moves to a positive level. The more the lithium-ion battery returns to the positive level, the higher the charge and discharge capacity. Generally refers to the 26650 lithium battery capacity, that is, the charge and discharge capacity.
