Fiber lithium batteries have broad application prospects and the industry is still in its infancy.

Fiber lithium battery, also known as fiber lithium ion battery and fiber polymer lithium ion battery, is a one-dimensional energy storage material that can be processed into any shape as needed. Fiber lithium batteries have the advantages of good cycle stability, light weight, stretchability, and good weavability, and have broad application prospects in smartphones, smart wearable devices and other fields.

In recent years, fiber lithium batteries have become a research hotspot in countries around the world. In September 2021, the team of Professor Peng Huisheng from the Department of Polymer Science of Fudan University in my country published the research results of a new type of fiber lithium battery in the internationally authoritative academic journal “Nature”. The scientific research team used the change of battery internal resistance with length to successfully prepare a new type of fiber lithium battery. Fiber lithium battery with excellent comprehensive electrochemical performance and safety performance. In December 2021, a research team from the Massachusetts Institute of Technology in the United States successfully prepared a 140-meter-long flexible fiber lithium battery.

Fiber lithium batteries are products in the lithium battery market segment. In March 2022, the National Development and Reform Commission and the National Energy Administration issued the “Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan”. The document clearly proposed to increase the research and development of new lithium-ion batteries. In recent years, as the prosperity of the new energy storage industry has continued to increase, my country’s enthusiasm for lithium battery research and development has continued to rise, which has brought broad development space to the fiber lithium battery industry.

According to the “2023-2028 China Fiber Lithium Battery Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Smartphones and smart wearable devices are the main application areas of fiber lithium batteries. In recent years, with the continuous breakthroughs in high-tech technologies such as artificial intelligence, the Internet of Things, and 5G, the development speed of my country’s smart wearable device industry has continued to accelerate. Fiber lithium batteries have the advantages of good cycle stability, good flexibility, and can provide continuous and effective power supply for a long time. In the future, they are expected to be widely used in smart wearable devices such as smart oximeters, smart bracelets, smart watches, and smart glasses.

my country’s fiber lithium battery industry is in its infancy, and the products have not yet been commercialized. Local companies such as Guangdong Silver Jubilee Technology Co., Ltd., Yantai Taihe New Materials Co., Ltd., Shengxin Lithium Energy Group Co., Ltd., Shenzhen Huicheng Information Technology Co., Ltd., and Yunnan Yuntianhua Co., Ltd. have begun to deploy fiber lithium batteries. R&D and production track. Among them, Taihe New Materials is building a pilot production line for fiber lithium batteries. It is expected that in the future, driven by technological innovation, the industrialization process of fiber lithium batteries in my country will continue to accelerate.

Industry analysts said that fiber lithium batteries, as a new type of lithium battery, have excellent performance and are expected to be widely used in the field of smart wearable devices in the future. At present, my country’s fiber lithium batteries are in the early stages of industry development and have not yet been commercialized. In the future, as local companies and related scientific research institutions continue to increase research efforts, my country’s fiber lithium batteries will gain broad market prospects.
