The left side of the lithium iron phosphate battery is an anode composed of an olivine structure material, which is connected to the battery with aluminum foil. On the right is the negative electrode of the battery composed of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil.

The "blade battery" adopts a new and familiar CTP (Cell to Pack) module free structure design, which eliminates the intermediate module link and directly integrates the battery cells into a battery pack. If we disassemble the battery pack of BYDIHAN, we can get a pile of single batteries with a length of 1 m, a width of 10 cm and a thickness of less than 2 cm. These single batteries are closely arranged and inserted into the battery pack like "blades", so they are named as blade batteries

In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

What is the development prospect of lithium battery pack industry in the next few years? Where is the development direction? Lithium battery affects the industrial reform of new energy fields such as energy storage, and relates to the development of China's new energy vehicle market. With the in-depth development of national environmental protection, the development scale of China's lithium battery industry will become larger and larger in the next few years. So, what is the future development prospect? Where is the development direction? Let's listen to what these industry leaders say. 1、 Changes in the application field of lithium batteries Since 2015, the industrial structure of lithium battery packs in China has changed significantly, and the demand for power lithium batteries has grown rapidly. In 2016, the power lithium battery market accounted for
