18650 & 26650 Lithium-ion Cylindrical Battery Production Line Building and Material Supply Project Jun 28,2019

Project Name: 18650 & 26650 lithium-ion cylindrical battery production line building and material supply project


Description: Xiamen TOB New Energy Technology Co., Ltd. designs and builds a 18650 & 26650 lithium-ion cylindrical battery production line for the customer's battery factory. We provide a full set of equipment and raw materials for battery production, and TOB New Energy dispatches engineers to the factory for equipment Assembling and debugging until the battery production line can fully operate and produce qualified 18650 & 26650 battery products.


Date: From January 2018 to January 2021


Location: Southeast Asia



After a long period of investigation and technical accumulation, the customer decided to enter the field of lithium-ion batteries.


This cylindrical lithium-ion battery with a diameter of 18.0mm or 26.0mm and a height of 65.0mm is a classic model of lithium-ion batteries. It has the characteristics of large capacity, long life and high safety performance, and because of its small size, light weight and convenient use, it is favored by consumers. With the continuous deepening of people's research on 18650 & 26650 battery technology, the consistency and safety of 18650 & 26650 batteries have reached a very high level. As the earliest lithium-ion battery, 18650 & 26650 battery is also the most mature and stable battery combination in the world, and it still occupies the leading position. This is also the main reason why the customer set the first lithium-ion battery production line as 18650 & 26650 cylindrical batteries. It is believed that the construction and commissioning of this production line is just the beginning, which will lay a solid foundation for customers to follow up with other projects in the battery field.
