[0002] Lithium-ion batteries are a new generation of green high-energy batteries with excellent performance and have become one of the key points in the development of high-tech. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, pollution-free, small size, small internal resistance, less self-discharge, and many cycle times. Due to the above characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, laptop computers, cameras, digital cameras, etc.
