Improved energy conversion efficiency through the development of amorphous alloys and lithium ion batteries for hybrid electric vehicles that were the first in the world to enter commercial use

Hitachi has been undertaking ongoing research and development in the field of metal materials. High-quality amorphous metal materials have been developed and supplied all over the world. Use of these materials has improved energy conversion efficiency and reduced power losses, and Hitachi has released transformers with significantly improved energy efficiency. These products help prevent global warming by reducing CO2 emissions, as well as addressing the world’s increasing demand for power. Lithium ion batteries for HEVs (hybrid electric vehicles) have also been developed and supplied for use as an energy source in HEVs that are fuel-efficient and make a major contribution to controlling CO2 emissions. These batteries are already in mass production, and this contributes to the development of HEVs by automobile manufactures, resulting in improved fuel efficiency and reduced exhaust gases as well as contributions to CO2 emissions control.
