Lithium -ion batteries include liquid lithium -ion batteries (LIB) and lithium polymer batteries (PLIB). Among them, liquid lithium -ion batteries refer to secondary batteries that are embedded and negative. Lithium compound LICOO2, LiniO2 or Limn2O4 are used, and the negative electrode uses lithium -carbon intercocal compound LIXC6. The typical battery system is:

　　(-) C | Lipf6-EC+Dec | LICOO2 (+)

　　Positive reaction: LICOO2 = li1-xCoo2 + xli + + xe-

　　Negative reaction: 6C + XLI + + XE- = lixc6

　　Total response of battery: LICOO2 + 6C = li1-xCoo2 + lixc6

　　The principle of lithium polymer battery is the same as liquid lithium, and the main difference is that the electrolyte is different from liquid lithium. The main structures of the battery include three elements: positive, negative and electrolyte. The so -called lithium polymer battery means that at least one or more of these three main structures use polymer materials as the main battery system. In the developed lithium polymer battery system, polymer materials are mainly applied to positive and electrolytes. The positive material includes inorganic compounds used in conductive polymer polymer or general lithium -ion batteries. Electrics can use solid or glue polymer electrolytes or organic electrolytes. Generally lithium ion technology uses liquid or colloid electrolyte, so it needs to be solid. The second packaging to accommodate the combustible active ingredients, which increases weight, and also limits the flexibility of the size.

　　The new generation of lithium polymer batteries can be achieved in theory, diverse shapes, and improved the flexibility of battery design, so that they can cooperate with product needs to make some shapes and capacity batteries, and for application equipment developers A high degree of design flexibility and adaptability are provided on the power solution to maximize their product performance. At the same time, the unit energy of the lithium polymer battery increases by 10%compared to ordinary lithium -ion batteries. Its capacity and cycle life are significantly improved compared to lithium -ion batteries.
