Sony Develops 1.2 kWh Li-ion Module for Stationary Applications; Olivine-type Lithium Iron Phosphate
juuli 1, 2010 ·

Sony has developed an energy storage module using lithium-ion rechargeable batteries made with olivine-type lithium iron phosphate as the cathode material. Key features of olivine-type lithium iron phosphate cell include high power output, long-life performance and excellent thermal stability. Sample shipments of the new module are scheduled to begin from June, 2010.

The newly-developed module offers 1.2 kWh capacity. Multiple modules can be connected either in series or in parallel to expand to a higher voltage or capacity.

Each module is compatible with a high power output maximum of up to 2.5 kW, and can be used for various stationary power supplies such as UPS (uninterruptible power supply) for data servers or as a backup power supply for mobile phone wireless base stations.

Quick Specs
# Capacity: 1.2kWh
# Nominal voltage: 51.2V
# Maximum output: 2.5kW
# Dimensions: 431 x 420 x 79mm
# Weight: approx. 17kg

Internal battery usage can be controlled safely by monitoring the state (voltage, current, temperature) of the internal batteries and communicating this to a linked external battery management system.

Sony estimates a 10-year useful life for the module with one charge-discharge cycle per day.

This energy storage module will be on display at the China International Battery Fair 2010 (held from 24-26 June 2010) in Shenzhen.
