It doesn't matter. The battery cannot be packaged in a plastic case.
The battery we use is a plastic case, mainly because the plastic case is inexpensive to make and does not leak electricity. There is actually a metal-cased battery cell inside, just like the cell phone battery. (Lithium-ion polymer batteries are wrapped in a metal film, like the built-in battery of MP3)
Do not use it. First, you destroyed the internal structure. Time, leaking lithium batteries are toxic. Do not contact fire sources, and the gasification and dispersion are dispersed in the air for a long time, which is harmful to the human body.
According to the different electrolytic materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteriesuide (liquefied lithium-ion battery, called LIB) and lithium-ion polymer batteries. (Lithium-ion polymer battery, PLB for short) or lithium-ion plastic batteries (PLB for short). The positive and negative electrode materials used in polymer lithium ion batteries are the same as liquid lithium ions. Positive electrode materials are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The principle of operation of the battery is also basic. The main difference between them is the electrolyte. Liquid lithium-ion batteries use liquid electrolytes, while lithium-ion polymer batteries use solid polymer electrolytes instead. This polymer can be “dry” or “colloidal”. Currently, most of them use polymer gel electrolytes. .
