"Why are lithium batteries better than lead-acid batteries?" "How to extend the service life of lithium batteries?" Dr. Mao Huanyu, general manager of BAK Battery, explained the working principle and use skills of lithium-ion batteries, and answered questions from the audience.

　　The use of lithium batteries is completely different from lead-acid batteries

　　Dr. Mao introduced that lithium-ion batteries have been widely used in daily life. For example, mobile phone batteries and laptop batteries are basically lithium batteries, and power batteries have also begun to develop. He pointed out that lithium batteries and lead-acid batteries have very different internal reactions and usage methods.

　　Lithium batteries are characterized by small size, light weight, and high energy storage per unit mass. The internal electron movement is a physical change, so the battery has a long service life. Lead-acid batteries are characterized by low requirements for the use environment. It can still be used in the environment, but because the internal charge and discharge process is chemically changed, the service life is short.

　　"Although lithium batteries have so many benefits, there are still some problems to pay attention to if you want to extend its life and allow electric bicycles to ride longer." Dr. Mao pointed out that the current use of power batteries is to group batteries, The series-parallel connection of single cells is realized, and because of its characteristics, lithium battery packs have high requirements for the consistency of the cells. “If one of the batteries in a group is different from the other batteries, the effect of the whole group will be reduced.”

　　Therefore, consumers of lithium-ion electric bicycles must pay attention to the care of the battery when using it.
