With the help of new materials and additional improvements, researchers at Siemens have managed to make lithium-ion batteries safer and extend their service life. As part of the joint research project Intrinsically Safe Battery (EiSiBatt), which is funded by the German Ministry for Economic Affairs and Energy, the engineers developed a new cell chemistry until it was sufficiently mature for general application. As a result, it is now possible to create lithium-ion batteries that are very safe, even when they are overcharged, and that last for a much higher number of charge-discharge cycles (20,000) than the previous top value of around 5,000.
