High Polymer Lithium ion Battery New Market
The main structure of general battery includes three elements: positive pole, negative pole and electrolyte. The so-called polymer lithium secondary battery refers to the battery system that USES the polymer material at least one or more of the three elements. In the development of polymer lithium secondary batteries, goiton materials are mainly used in the anode and electrolyte. The anode materials include conductive polymer organic sulfur compounds, or inorganic compounds used in lithium-ion batteries in general. Electrolytes can be solid or colloidal polymer electrolytes or organic electrolytes. The cathode usually USES lithium metal or lithium interlayer compound.
As the polymer lithium secondary battery has many advantages, many manufacturers have been competing to launch the commercialized polymer lithium secondary battery, including Hitachi Maxell of Japan, Yuasa, Ultralife of Toshiba USA and Electrofuel of Moltech Canada. These companies value their ultra-thin features. Generally, the thickness of the macromolecular lithium secondary battery is about 2-4mm, while the minimum thickness of the existing lithium ion battery is 6mm, which can be reduced by at least 50%. Therefore, it can provide considerable elastic space for the manufacturer to design the product.
If the polymer lithium secondary battery is compared with the current lithium ion battery in the market, it can be found that the polymer lithium secondary battery has considerable development space in terms of shape, charge and discharge, reliability and environmental protection. In terms of shape, the macromolecular lithium secondary battery has many advantages, such as being able to be thin, arbitrarily shaped and arbitrarily shaped. Therefore, it can be made into any shape and capacity battery according to the requirements of the product. In terms of charge and discharge, the energy density of the polymer lithium secondary battery is more than 50% higher than that of the lithium ion battery on the market, because the polymer anode material and lithium metal anode are used. In terms of reliability, as the electrolyte of polymer lithium secondary battery is made of polymer material, there will be no leakage and combustion explosion and other safety problems.
