Which is better, polymer battery or lithium battery?

Polymer batteries are better. Lithium batteries are now almost eliminated. Lithium batteries use metal lithium as the negative electrode. The earliest is the lithium manganese dioxide battery, the reaction method is redox reaction Li+MnO2u003dLiMnO2. The voltage of lithium metal battery is about 3.0~3.6, depending on the cathode material. At present, lithium metal batteries are still mainly used in button batteries, and the others have been replaced by lithium polymer batteries or lithium batteries. It should be that lithium is a metal that is more active than sodium, it is easy to lose the battery, that is, it is easy to undergo oxidation reaction. Needless to say, even the hydrogen in the water can be replaced. Lithium batteries almost react when exposed to air. In the past, you can often see lithium batteries used to make fires in the field, which is to smash the batteries, and the lithium inside reacts with air to release The huge heat shows how dangerous lithium batteries are. The difference between lithium battery and lithium battery is that it does not contain metal lithium. Lithium battery is a rechargeable battery, which depends on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when recharging the battery, Li+ deintercalates from the positive electrode and inserts into the negative electrode through the electrolyte. The negative electrode is in a lithium-rich state; the opposite is true during discharge. Polymer battery is actually a kind of lithium battery, the principle is the same as that of lithium battery. Unlike lithium batteries, the electrolyte inside is replaced by electrolyte, so it is safer and can be smaller.
