Lithium-ion battery components
(1) Battery top and bottom covers
(2) Positive electrode - active material is usually oxide lithium and cobalt
(3) Separator - a special composite membrane
(4) Negative electrode - the active material is carbon
(5) Organic electrolyte
(6) Battery case (divided into steel case and aluminum case)
The usual lithium battery manufacturing process in small phone repair shops portable involves cutting out the corresponding size and shape of the required battery on a small template. The inner surface of the zinc shell is covered with a composite layer and a diaphragm, then the positive and negative electrodes are fixed on the inner surface of the zinc shell (connect the ballast microcircuit if necessary), then all the zinc shell is covered and fixed, and finally the electrolyte isfilled and sealed, then cover it with plastic packaging
