SANYO to Electrify Its Nickel Metal Hydride Batteries
With New Electrode Material 'Superlattice Alloy'
Tokyo, November. 27, 2003---SANYO Electric Co., Ltd. the world's leading producer of rechargeable batteries announce the successful development of a new electrode material, 'Superlattice Alloy' for Nickel Metal Hydride batteries. 'Superlattice Alloy' has a different make up than conventional material this distinctive structure helps it to achieve its high performance. SANYO will continue to move forward in the development of Nickel Metal Hydride batteries using this new electrode material with higher capacity and higher performance than conventional material.
Will start using batteries with 'Superlattice Alloy' material for mobile phones which need to work in low temperatures and are under strong price constraints. Also plan to utilize the high capacity, temperature and discharge features of 'Superlattice Alloy' for electric power tools and HEVs (Hybrid Electric Vehicles).
The development of the negative electrode material 'Nickel Hydrogen-Absorbing Alloy' contributed to the high performance of the Nickel Metal Hydride battery. 'Nickel Hydrogen-Absorbing Alloy' was superior from the point of utilization so the basic structure was maintained while continuing with improvements. However, this time SANYO has succeeded in the utilization of a new negative electrode material, 'Superlattice Alloy' that has a completely different structure and realized high performance for Nickel Metal Hydride batteries. Expect Nickel Metal Hydride batteries to evolve further in the future.
Main features
1. High capacity that exceeds conventional Nickel Metal Hydride batteries
2. Ideal for high power use with excellent discharge property and improved low temperature characteristic
3. Low cost possibilities
4. Positive results attained from technology cooperation with the Toshiba group
(1) High capacity that exceeds conventional Nickel Metal Hydride batteries
Possible with 'Superlattice Alloy' to increase capacity approximately 25% compared to conventional negative electrode material.
(2) Ideal for high power use with excellent discharge property and improved low temperature characteristic
'Superlattice Alloy' has a superior discharge performance than conventional negative electrode material*1, making it ideal for mobile phones that are used in low temperatures and for electric power tools and HEVs (Hybrid Electric Vehicles) that require a high rate of discharge.
(3) Low cost possibilities
Conventional negative electrode material*1 when charged and discharged repeatedly would break into tiny particles from the expansion and contraction. To prevent this phenomenon of tiny particles breaking up, the material cobalt was essential. Cobalt is a precious resource that raised costs for Nickel Metal Hydride batteries. 'Superlattice Alloy' experiences less particle break up so it's possible to decrease the amount of cobalt or use no cobalt at all, resulting in an increase in cost competitiveness.
*1 Conventional negative electrode material: AB5 model called 'Nickel Hydrogen-Absorbing Alloy'
(4) Positive results attained from technology cooperation with the Toshiba group
Toshiba Corporation and Toshiba Battery Co., Ltd. announced in 2000 the developed of 'Superlattice Alloy' for Nickel Metal Hydride battery use, but didn't reach the deployment stage. After Toshiba Battery Co., Ltd. transferred its Nickel Metal Hydride battery business to SANYO in April 2001, SANYO continued the research for utilization of 'Superlattice Alloy'. SANYO succeeded in improving the life cycle of the battery making it ready for utilization. This achievement is the result of SANYO Electric Co., Ltd. and the Toshiba group's collaborative technology efforts.
