Safe batteries for the "Energiewende"

Lithium-ion batteries can be very efficient, reliable and safe energy storage systems. They are able to compensate the fluctuations of renewable energy and are thus key elements for a safe and economically viable energy supply within the German "Energiewende". However, in practice and with regards to standardization there are critical safety loopholes in stationary storage systems, among those also PV home storage systems. There are also no standardized and sufficiently meaningful tests of the cycle life of these products.
