Li-ion cells deliver an increase in power density compared to conventional lead-acid, Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMh) batteries enabling the same power to be provided from smaller installations. At 25°C, the new Yuasa LIM50E cells provide a typical 1-hr rate capacity of 50 Ah from a cell measuring 171 x 44 x 113 mm high and weighing 1.7 kg. Nominal voltage is 3.7 V with operating voltage range from 2.75 to 4.1 V.

The fully-sealed stainless steel and PET insulated casing ensures no gas is released under normal operation and the LIM50E cells can be installed and used in any orientation.

Specifications include maximum continuous discharge current of 300 A, up to 2000 cycles to 80% of initial capacity, impedance of 0.55 mΩ (measured at 1 kHz) and operating temperature range from -25 to +60°C for storage, charge and discharge conditions. Terminal types are M8 male thread with torque from 9 to 13 Nm.

Design life is 10 years and applications include UPS and standby power in industrial, telecommunications and computer datacentres, next-generation transportation systems that rely on regeneration systems and large energy storage systems for solar and wind power installations along with large portable power applications.
