Nissan plans to "add lightness" by using Li-ion instead of NiMH
Current hybrid vehicles on the road today run on nickel-metal hydride rechargeable batteries. Nissan and NEC plan to buck the trend and adapt lithium-ion battery technology into upcoming hybrid vehicles.
"Together Nissan and NEC's engineers have addressed the key challenges of cost, performance, safety and reliability. We believe that we have a breakthrough technology: the lithium-ion battery produce we will produce," Nissan executive vice-president Carlos Tavares said.
Lithium-ion batteries are generally regarded as superior to nickel-metal hydride for higher capacities in smaller form factors. This will enable automakers to implement hybrid technology power source into a smaller and lighter package. Furthermore, weight savings afforded by lithium-ion technology will positively affect nearly all aspects of the vehicle’s characteristics.
"Co-development with Nissan has enabled a superior-class battery that we expect to spread in the market at an unmatched speed," added NEC executive VP Konosuke Kashima.
The big concern over using lithium-ion batteries in automobiles is that the battery technology is more prone to safety concerns, such as fires or explosions. Lithium-ion batteries are also generally less durable than nickel-based designs.
Nissan and NEC plan to research and develop the technology to meet safety standards and to begin production in 2009. The evenly split joint venture between the two companies involved in the development is imaginatively called “Automotive Energy Supply Corporation,” which will supply batteries for Nissan's first internally developed hybrid car planned for launch in 2010.
“The evolution of battery technology will be a deciding factor in bringing tomorrow's electric vehicles closer to reality,” Nissan Senior Vice President Minoru Shinohara said at a news conference. Shinohara added that the venture’s battery technology has twice the power of conventional batteries at half the size.
Last September, Nissan broke ties with Toyota to move away from nickel-metal hydride technology. Toyota has since then led the automotive industry in hybrid vehicle sales and has recently launched the world`s most expensive (and luxurious) hybrid. Although hybrids are met with much fanfare, most analysts believe that such vehicles will make up only 6 percent of market by 2013.
