Accelerating the production of lithium-ion cells
Developers from Bosch and scientists at the Technical University of Munich (TUM) are using neutrons to analyse the filling of lithium ion batteries for hybrid cars with electrolytes. Their experiments show that electrodes are wetted twice as fast in a vacuum as under normal pressure. One of the most critical and time-consuming processes in battery production is the filling of lithium cells with electrolyte fluid following the placement the o...
