Lithium ion rechargeable battery can be used repeatedly, and thanks to the advantageous features of its compact size and light weight is now widely used, and replaced the Nickel metal hydride batteries originally used for mobile applications such as laptop PC, cellular phones and others. And now, it has been adopted as the battery for eco-friendly cars by its distinct features for better charging efficiency than the Nickel metal hydride battery and memory-effect-free performance. In actual application for vehicles,many cells needs to be combined as a module to form a battery pack with additional control circuit to monitor voltage or temperature for safety use. Moreover reliability under severe conditions and high safety level in case of crash or accident is required.
The Hitachi's R&D Group is developing battery of "long operating life", "high power", "high energy density", "high durability", "safety", and "low cost" for automotive applications.
