Dry lithium batteries use metallic lithium as the cathode, LiI3 as the positive electrode, and LiI as the electrolyte. This kind of battery must exist in anhydrous solid phase conditions, in other words, it must exist in a solid strong alkali Environment

Another kind of lithium-ion battery is the commonly used mobile phone battery. The negative electrode is Li Co or Mn salt, and the positive electrode is the corresponding high-price salt (Li maintains 1 price, Mn, Co change the price ) The pH of this kind of battery should be adjusted to a weakly alkaline environment, because acidity can easily cause hydrolysis, while strong alkalinity can easily convert Li into LiOH

A reasonable pH is generally between 8 and 10
