Preface
As the traditional models of lithium-ion batteries, 21700 and 18650 cylindrical batteries have a wide range of applications in consumer electronics, power tools, electric vehicles and other fields, and maintain a large demand in the market. Especially in some applications where there are special requirements for battery size and shape, these two cell models are still preferred. For example, in some portable electronic devices, power tools, and some electric vehicles with low range requirements, 18650 and 21700 cells are still the main battery choice.
Changhong Sanjie New Energy Co., Ltd. was established in 2014, focusing on the research and development and production of high-rate cylindrical lithium batteries, with outstanding team, quality and service as the core of the team, safety first, leading technology, integrity management as the business philosophy, with 6 fully automatic homogenization, South Korea automatic assembly and testing system, with a production capacity of 1.3 million / day.
Recently, Changhong Sanjie New Energy Co., Ltd. has launched a series of high-rate cylindrical cells, including 21700 and 18650 cells.
