Hitachi shows a lithium-Ion battery with 10 years battery life
Hitachi has created a rechargeable lithium-ion battery cell that battery life of more than 10 years.
Lithium-ion (Li-ion) are found in consumer electronics such as mobile phones and laptops, Hitachi said the new technology lead for the first time in batteries for electric vehicles and industrial wind parks.
Although Li-ion Laptop battery is about four times the power density than lead acid batteries, the relatively high cost and less than five years, life is not favorable for the great tasks and schedules in batteries, lead acid batteries up to 10 years before the can spare.
The company said on Monday had developed a new oxide composite material - a lithium-manganese spinel (LiMn204) - to the cathode of the Dell inspiron 1440 battery , improving their resistance to acid in the electrolyte, an important determinant of life. It also reduces the formation of crystals in the electrolyte, which also shortens the life of a battery.
Although the company is not all the details about these changes unless said that the cathode consists mainly of manganese in place of the commonly used cobalt, manganese is to get a lot easier, but so far there has been enough of this battery chemistry.
The Dell GD761 battery was a prototype with Shin-Kobe Electric Machinery Co Ltd and in cooperation with the New Energy of the Japanese Government and the Industrial Technology Development Organization established to promote research of energy produced. Hitachi has not indicated when the battery would go into production.
Hitachi, which has its fourth annual loss for the year ended 31 Reported in March, has said it will return to focus on green businesses, including batteries for electric vehicles as part of its plan to profitability.
Last year, researchers said at the Technical University of Graz in Austria, it was a silicone gel that make Li-ion batteries 10 times more efficient could be developed.
