polymer lithium battery: the future of electrical energy storage

　　'Lithium battery' is the leading technology in the field of power storage today, and its unique performance advantages make it widely popular. With its high energy density, fast charging and long service life, this kind of battery is gradually replacing traditional lead-acid batteries and nickel-metal hydride batteries and becoming the first choice for electronic equipment, electric vehicles and energy storage systems.

　　How polymer lithium battery work

　　The working principle of 'polymer lithium battery' is based on the reversible insertion and removal process of lithium ions between the positive and negative electrodes. During the charging process, lithium ions migrate from the positive electrode (such as lithium cobalt oxide, lithium iron phosphate, etc.) to the negative electrode (usually graphite), and move in the opposite direction during discharge. This reversible chemical reaction enables 'polymer lithium battery' to be repeatedly charged and discharged, enabling efficient storage of electrical energy.

　　Advantages of polymer lithium battery
