4 mm diameter: minimum charge lithium battery in fertilizer production

With a diameter of 4 mm and a height of 5 mm, this world's smallest rechargeable lithium battery is a "mini" and very powerful. Luoyuanfu, chief engineer of Hefei lithium-energy technology Co., Ltd., told reporters that the battery is lithium-titanate battery. Unlike traditional lithium-ion batteries, it has extremely strong temperature resistance and can be charged at -35 °C to 65 °C. In addition, the charging efficiency is also very amazing. Generally, the battery takes several hours or more to fill, and the battery can be fully charged in just two minutes to meet the need for rapid charging. At present, the battery is mainly used for recording pens, hearing aids and other electronic equipment.

The world's smallest rechargeable lithium battery was put into production yesterday. According to the report, the first phase of the project investment of 40 million yuan, the annual output value of 200 million, the second phase of the project will also be put into production in October this year, by which time the annual output value will reach 600 million yuan.
