1, lithium-ion batteries and battery packs, this kind of battery is a kind of rechargeable batteries, the use of lithium ions in the positive electrode and the negative electrode between the movement to work. With the advantages of high energy density, low self-discharge and no memory effect, lithium-ion batteries are widely used in high-end digital products, power vehicles and energy storage.
2, polymer batteries, this battery is a variant of lithium-ion batteries, the use of polymers as the positive or negative electrode of the material. Polymer batteries are thin, light, flexible and safe, and are suitable for wearable devices, smart cards and other products.
3, fuel cell, this battery is a device that converts chemical energy directly into electrical energy, using hydrogen and oxygen and other fuels in the catalyst under the action of the redox reaction to generate electric current. Fuel cells have the advantages of high efficiency, low pollution, long life, etc., and can be used in automobiles, aviation, aerospace and other fields.
4, power batteries and battery packs, this battery is a specialized battery to provide energy for the power system, usually using lithium-ion or nickel-metal hydride and other materials. Power battery has high power, high cycle life, good low temperature performance and other characteristics, mainly used in new energy vehicles, electric bicycles, electric motorcycles and other transportation.
