Scientists at the Technical University of Munich (TUM) have developed a new cell design for lithium-ion batteries for material characterisation

The "battery with windows" makes it possible to measure the lithium concentration within an electrode as a function of depth during charging and discharging with the help of neutrons. The new technique can help clarify reaction mechanisms in batteries and understand ageing phenomena.
