As the world's largest lithium battery production and manufacturing base and the world's second largest producer and exporter of lithium batteries, China's lithium batteries have accounted for 40% of the global market share. Lithium-ion batteries are widely used in cell phones, notebook computers, power tools, street light backup power, aerial lights, small household appliances, and have a huge application group. With the shortage of energy and the pressure of environmental protection in the world, the demand for lithium batteries will continue to grow. Lithium-ion batteries have become the mainstream. Main advantages: high energy, long service life, high rated voltage, high power tolerance, low self-discharge rate, light weight, high and low temperature adaptability, green and environmental protection. Main disadvantages: relatively high price, relatively narrow temperature range, there are certain safety risks (need to add protection system).
