Hong Kong PolyU develops 'fabric lithium battery' smaller and thinner

According to the Hong Kong 'Ming Pao' website, in recent years, popular wearable electronic products, such as heating jackets and insoles, require lithium batteries. However, the quality of lithium batteries is hard and makes users feel uncomfortable. The Department of Textiles and Clothing of The Hong Kong Polytechnic University (PolyU) has developed an ultra-soft 'fabric lithium battery' that can be folded and bent to a diameter of about 1 mm. It can be folded 1,000 times without detrimental performance. The team hopes that the 'fabric lithium battery' can be used in the future. For smart watch straps, heat-generating clothing, etc., the product is more durable while being comfortable to wear. The team from the Department of Textiles and Clothing of the Hong Kong Polytechnic University spent 3 years to complete the research and development of foldable fabric lithium batteries. Professor Zheng Zijian of the Department of Textiles and Clothing at PolyU said that the team spent 3 years to complete the research and development of fabric lithium batteries. The principle is to use polymer-assisted metal deposition to uniformly deposit highly conductive metals on treated fabrics, such as cotton and carbon. Cloth, 'makes the material conductiveheng Zijian said that the fabric is smaller and thinner than traditional lithium batteries, with a thickness of less than 0.5 mm. He gave an example, because fabric lithium batteries can be folded and bent, which is suitable for making smart watch straps, increasing the power storage of smart watches and making the products more durable. 'In the past, these smart watches were fully charged for one day. In the future, if you add a strap made of lithium batteries, you can use it for up to two days after charging,' Zheng Zijian said.
