Lithium-ion battery withstands 10,000 recharges

Officials at the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in Germany claim that they have made improvements to lithium-ion batteries that can be recharged up to 10,000 times, while retaining a charging capacity of 85 per cent.

One of the main obstacles in the widespread adoption of electric vehicles is expensive batteries and the fact that they only last between three to ten years. If the improved lithium-ion batteries are used, they could last 27 years, if recharged on a daily basis.

The ZSW researchers said that batteries could endure more charging through electrode thickness changes or how much the electrodes compact during use and the type of conducting agent used in their construction when engineered in a new way. The improved batteries are approximately four times denser than standard batteries, which are 1,100W per kg. They are ideal for solar or wind farms and automotive vehicles.

The availability of the redesigned batteries has not been announced, but ZSW notes that that it has designed the new cell type itself as well as developing the manufacturing process used to make the battery. They've also made several prototype batteries in the 18650 format.
