BMZ will present in Hall B2, Booth 479 at electronica 2006, in Munich, Germany, November 14-17, 2006 an extremely powerful, and at the same time environmentally friendly, nanophosphate lithium-ion rechargeable battery from the U.S. manufacturer A123Systems. The ANR26650M1 has a 10x life cycle vs. conventional lithium ion batteries and allows for much higher power density, or rate of charge and discharge. The battery has the ability to recharge to 90% of its capacity in five minutes. 3000 Watts per Kilogram guarantees the highest performance in the smallest form factor.
The new cell, which for the first time uses a nanophosphate positive electrode (cathode), has a nominal capacity and voltage of 2.3 Ah, 3.3V. The internal impedance (1kHz AC) is 8 mΩ typical. Maximum continuous discharge is 70A and pulse discharge at 10 sec is 120A for each cell. With an operating temperature range of -30°C to +60°C, the ANR26650M1 allows for use in harsh environmental conditions.
A123 nanophosphate lithium-ion high-performance cells do not use any toxic heavy metals and are therefore, in contrast to nickel cadmium cells, particularly environmentally friendly. Due to the use of thermally stable, non-combustible active materials, the ANR26650M1 cell offers a high level of safety, even without additional protection circuitry. This feature is a significant distinction compared with conventional cobalt-based lithium ion cells. Because nanophosphate lithium-ion cells do not require any protection components, this allows future high performance rechargeable batteries to be manufactured much simpler than in the past and therefore, also makes them suitable for low volume production quantities.
