According to ISNA, Hysayv Yamashyg·h, a researcher at Toyota's battery technology at a conference in Tokyo said,lithium-ion batteries is a key technology for electric cars and there is the clear need to improve the technology and performance.

Improving the performance of lithium-ion battery technology is a big issue for the traditional  automakers such as Toyota and newcomers such as Tesla Motors.

Manufacturers of battery electric vehicles, plug-in hybrid-electric vehicles as well as gasoline-electric hybrid cars have to work hard to design advanced battery technologies to improve haul traverse, battery life and safety.

Toyota's petrol-electric technology has taken the lead and are ready to supply almost all-electric car is called 'Prius Prime ". It also wants offer all kinds of electric car models for 2019.

According to Reuters, Toyota engineers using techniques that are designed in collaboration with a laboratory and four Japanese universities, have managed how lithium ions move within the electrodes, th better view and the new observations will help them in new designs to increase
battery life and the distance that electric vehicles can travel.
