The “soft-packaged ultra-thin lithium-manganese battery technology and technology” developed by a company in Wuhan Economic and Technological Development Zone passed the expert appraisal meeting organized by the Science and Technology Department of Hubei Province on the 3rd. Authoritative experts from Wuhan University and Wuhan University of Technology believe that The main technical indicators of this new achievement have reached the level of foreign similar products and the domestic leading level, which not only filled the domestic gap, but also broke the monopoly position of multinational companies in this field.


At present, the ultra-thin lithium battery that is in great demand on the market refers to a battery with a thickness of not more than 0.45 mm, which is as thin as a paper sheet, and is mainly used in the fields of smart cards and RFID tags. Due to the difficulty of processing, only the US SOLICORE company and the German Valta company (VARTA) can be produced in the world.

Bosell Corporation, located in the High-Tech Industrial Park of Wuhan Economic and Technological Development Zone, has been aiming at this high-tech project since its establishment in August last year, making full use of the rich experience of research and development of soft-pack lithium batteries for many years, using liquid lithium manganese flexible packaging battery solution. After nearly one year of hard work, overcoming all kinds of difficulties in the research and development process, we finally developed a number of ultra-thin lithium manganese batteries.

Experts believe that the innovation of this scientific and technological achievements is manifested in: First, independent research and development through the improvement of electro-hydraulic formula and battery post-treatment process, effectively overcome the problem of inflation; Second, the product has good high temperature resistance, can withstand 105 ° C for a short time The high temperature meets the requirements of the smart card heat sealing process, and has excellent storage and safety performance. Thirdly, it has developed a set of special tooling and equipment for mass production of ultra-thin lithium manganese batteries in flexible packaging, and designed and developed three types of 0.45mm lithium. The battery can be put into mass production to fill the domestic gap.

According to industry insiders, this product is a green power supply, does not contain any heavy metal elements, has good use and storage performance, the main technical indicators have reached the level of similar foreign products, of which the capacity exceeds 30% of similar products of American Solicore Company. Flexible packaging ultra-thin lithium manganese battery is suitable for smart cards and other fields, supplemented by RFID technology, which can greatly improve the security of smart cards, greatly expand its functions, meet the requirements of building resource-saving and environment-friendly society, and has broad market prospects. Produce good economic and social benefits.
