The ‘21700’ battery, which is 21 millimeters in diameter and 70 millimeters in height, boasts a 50 percent bigger capacity and longer lifetime than the previous ‘18500’ cylindrical battery, the company claimed. The company also expected the ‘21700’ battery would become a new standard for cylinder-type battery packs typically used in electric tools, golf carts, and bicycles.
Also in the show, the company introduced an electric energy storage system (ESS) with a 9.1 megawatt hour (MWh) capacity for power plants and industrial facilities, which would help boost energy efficiency by controlling energy inputs on needed basis. It also presented an ESS system for homes that can store excess energy from solar panels for later use.
The company’s other battery innovations included its new lithium-ion battery pack with a 50 percent more capacity that was fitted in BMW’s electric car i3 and solid-state battery technology. A lithium-ion battery using a solid electrolyte is considered to be safer and capable of storing more energy than the conventional liquid-state battery.
The InterBattery 2017 sponsored by Korea’s Ministry of Trade, Industry, and Energy is one of Asia’s top 3 battery tradeshows. It will be held between from September 27 to 29 at COEX Hall B in southern Seoul, Korea.
