Hitachi developed pure electric car lithium battery-would last 400 km

Hitachi has developed pure electric car lithium battery technology that the battery would last 400 km of pure electric vehicles (EV). Compared with the previous battery, the capacity increased to 2 times, driving distance than the current pure electric vehicle extension of about 4 percent. The electrode is made of a nickel alloy or the like, and a large amount of electric power can be stored by increasing the thickness and the like. But also improve the durability, even if repeated charge and discharge, performance will not be reduced. Hitachi said, and strive to achieve practical use in 2020.

The current sale of pure electric vehicles, Nissan's "LEAF" (hear the wind) charge can travel 280 km. If the driving distance of 400 km, should be able to greatly promote the popularity of pure electric vehicles.

Lithium-ion batteries are discharged or charged by turning lithium ions back and forth between the electrodes. To increase the charge and discharge capacity, it is necessary to increase the ion stored in the electrode. The Hitachi this time the development of the battery, the cathode material to easily store lithium ions as the main component of nickel, and the thickness of the electrode increased to 2 times the original, can increase the storage of ions. The negative electrode does not use the usual carbonaceous material, but the silicon is easy to store and release lithium ions as the main component. With these improvements, more electricity can be stored.

In addition, the "energy density" showing the performance of the battery is expected to be about twice as much as the original battery cell state, i.e., 320 watts per kilogram. Close to the lithium ion battery can reach the maximum. According to reports, if equipped with pure electric vehicles, under standard conditions can travel about 400 km.
