Samsung 21700 Cells: The Industrial Standard for High-Performance Lithium-Ion Battery Systems

As energy storage and electric mobility sectors rapidly expand, companies are increasingly focused on battery performance, safety, and reliability. Among the most trusted options in the market today are Samsung 21700 cells, known for their superior energy density and long cycle life. This article offers an in-depth look at the features, applications, and benefits of the Samsung lithium ion battery 21700, helping commercial users make informed sourcing and engineering decisions.

What Are Samsung 21700 Batteries?

Samsung 21700 batteries are cylindrical lithium-ion cells with a diameter of 21mm and a length of 70mm. Compared to the older 18650 format, the 21700 design delivers increased capacity and higher current output, making it ideal for applications requiring both power and longevity.

As a global leader in battery manufacturing, Samsung SDI produces some of the most reliable 21700 lithium-ion cells, widely adopted in electric vehicles (EVs), power tools, industrial equipment, and energy storage systems (ESS).
