The prosperity of the polymer lithium battery industry has increased, and standardization and high quality are its main development directions.

Polymer lithium battery, also known as lithium polymer battery, polymer lithium battery, and polylithium battery, refers to the use of polyacetylene, polymer conductive materials, polyparaphenol, polyaniline, etc. as the negative electrode, file alloy as the positive electrode, and solid polymer A chemical battery made of electrolyte. Polymer lithium batteries have the advantages of lightweight, high energy density, long cycle life, safety and reliability, and have broad application prospects in electronic products, new energy vehicles and other fields.

The polymer lithium battery industry has high technical barriers. Its production process includes preparing raw materials, stirring and pulping, coating, rolling, cutting, pole piece slitting, tab welding, cell preparation, insulation performance testing, packaging, etc. The smaller the volume, the more difficult and expensive the preparation of polymer lithium batteries. In the future, as my country’s polymer lithium battery technology continues to advance, its output and quality will be greatly improved.

The country attaches great importance to the development of the lithium battery industry. In November 2021, the Electronic Information Department of the Ministry of Industry and Information Technology organized the revision of the “Lithium-ion Battery Industry Specification Conditions (2021 Edition)”. The document clearly stipulates strict regulations on the volumetric energy density, cycle life and capacity retention rate of polymer single batteries. Driven by national policies, my country’s polymer lithium battery industry will gradually develop in a standardized and high-quality direction.

According to the “2023-2028 China Polymer Lithium Battery Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , The electrolyte of polymer lithium battery is solid polymer electrolyte (SPE), which is composed of polymer host and metal salt. Traditional lithium batteries mostly use organic liquid electrolytes, which have shortcomings such as low safety, easy volatilization, and easy leakage. Compared with organic liquid electrolytes, solid polymer electrolytes have excellent performance and lower production costs, and can reduce concentration polarization of batteries during charge and discharge. In recent years, my country’s battery companies have continued to be enthusiastic about the research and development of solid polymer electrolytes, driving the prosperity of the polymer lithium battery industry to continue to increase.

Research on polymer lithium batteries began in the 1970s and was not commercialized until 1999. my country’s polymer lithium battery industry started late, but is developing rapidly. Zhengye Technology, Ganfeng Lithium, Veken Technology, CATL, Zhuhai Guanyu, Yiwei Lithium Energy, etc. are the main players in my country’s polymer lithium battery market. Zhuhai Guanyu is a global leader in polymer soft-pack lithium-ion batteries. The company’s products are mainly used in the consumer electronics field.

Industry analysts said that polymer lithium batteries use solid polymer as the electrolyte, have excellent performance, and are widely used in many fields. As electronic product updates and iterations accelerate, the market demand for polymer lithium batteries will continue to grow. In recent years, my country’s battery companies have continued to increase their investment in research and development of polymer lithium batteries. As the technology matures, its production costs are expected to be further reduced, and the industry will gain huge room for development in the future.
