Research and development of Hong Kong polyu 'fabric lithium battery' smaller and thinner

According to Hong Kong 'Ming pao website reported that in recent years popular wearable electronic products, such as fever coat and insoles are need to use lithium batteries, but lithium battery quality of a material is hard, can make the user feel uncomfortable. The Hong Kong polytechnic university ( Polyu) Department of textile and garment, developed a super soft & other; Fabric lithium battery & throughout; , folding bending to ca. 1 mm in diameter, repeat folding 1000 times still nondestructive performance, team hope & other; Fabric lithium battery & throughout; In the future can be applied to intelligent wristwatch, fever, such as clothing product wear cozily and more durable.

says Zheng Zijian, a professor at the department of textile and garment, polyu team spent three years time to complete research and development of fabric lithium batteries, polymer auxiliary principle is the use of metal deposition, the high conductive metal uniformly deposited on the treated fabrics, such as cotton and carbon cloth, & other; Make material conductive & throughout; To replace general metal foil on the surface of the lithium battery, to act as a collection of fluid and improve the softness.

Zheng Zijian said, compared with the traditional lithium battery small and thin fabric, thickness of less than 0. 5 mm, for example, due to the lithium battery can be folded fabric bending, is suitable for making smart wristwatch, increase the smart watch store electricity, make products more durable.

　　“ Past these smart meter charge for 1 days, and made of lithium battery strap in the future, the charge is available at most 2 genius will no electricity & throughout; , Zheng Zijian said.
