TOYOTA, the Japanese auto maker, said they had improved the stability of lithium-ion batteries, which could safely store more electricity without the need for significant extra costs. The message may have recently suffered Galaxy Note 7 battery explosion Samsung Brief Encounter sigh.
TOYOTA said the plug-in Prius hybrid Prime will use lithium ion battery. In the case of electric power, the car can rely on pure power for 37.3 miles, then start the gasoline engine.
Many lithium ion batteries use nickel, cobalt and manganese to produce electricity. This technology can save more electricity, the required charging time is shorter, and is considered to be more secure than other lithium-ion technology. However, if it is not properly designed, manufactured and controlled, the lithium-ion battery will still overheat or fire.
TOYOTA Prius chief engineer Koji Toyoshima said, in ten years, or to the development of lithium ion battery car stable in the tens of thousands of kilometers of mileage and safe operation is very difficult. "We double the battery and three times the reinforcement, so that it will not be a failure. Safety is the most important, "he said in an interview with the media.
In the traditional Prius, TOYOTA mainly used NiMH batteries, more mature, although from 2009 onwards they also began to use lithium ion batteries. At that time, the first batch of lithium ion batteries for all electric vehicles began to appear in the mass market, such as the Tesla's Roadster sports car and Nissan's Leaf.
