Hitachi claims battery life breakthrough

Hitachi has achieved a breakthrough in the design of lithium-ion batteries that it claims will lower production costs and extend lifespans to up to 10 years.

Researchers at the company have come up with a new design of cathode which combines manganese and cobalt with other substances.

The electrolyte in the battery has been improved to lengthen the life of the unit, and Hitachi is researching other changes to electrolytes to further extend the potential lifetime.

However, Hitachi said that laptop and phone users will not be the first to see the improvements, as the company is concentrating its efforts initially on industrial-grade batteries and storage.

The new technology was developed in association with the New Energy and Industrial Technology Development Organisation set up by the Japanese government to invest in power research.

 10 year life expectancy?
No longer have to replace the batteries in your electric car every year or so?
bloody marvellous.

 Supercapacitors are more promising for electric cars. I remember there was a company that was manufacturing them (I should check).

 hm, capacitors charge fast and can discharge fast but I'm not sure about storing a charge for long periods of time.. that's the long suit of batteries.

 They can store charge for sufficiently long periods of time. And have the advantage of not wearing out, or being made of heavy material.
