1.5v Dry Battery.New energy power lithium battery

　　The power battery is basically the power supply that provides a high-power power source for power tools, generally compared to the small battery that provides energy for portable electronic devices. Lithium batteries are generally used in electric vehicles, electric trains, electric bicycles, scenic sightseeing vehicles, balance scooters and other transportation vehicles to provide power. The capacity lithium battery is like mountaineering running requires endurance, that is, high capacity is required to maintain a long-term low-power discharge.

　　There is not much difference between capacity lithium battery and new energy power lithium ion battery in positive and negative electrode materials, electrolyte, diaphragm, but relative to power lithium ion battery, capacity lithium battery puts safety, cycle performance and cost in the first place, and does not require good rate performance and temperature performance. Therefore, the material indicators and battery material ratio requirements of capacity lithium batteries are very different from those of power lithium-ion batteries.

　　The two kinds of lithium batteries are different in the use of materials and production processes, and more objectively can be compared from the price. For example, the two lithium batteries have the same capacity, but the power lithium battery is much more expensive than the capacity lithium battery. The internal resistance of the power lithium battery is much smaller than the internal resistance of the capacity lithium battery, taking the 18650 lithium battery as an example, the cap of the power lithium battery with 3-5 times the discharge rate has PTC, and the internal resistance of 40mΩ-46mΩ will not exceed 50mΩ; 6-20 rate discharge generally does not have PTC internal resistance of about 20mΩ. Power type lithium battery discharge power is used in electric bicycles, balance vehicles and other electric tools of choice.
