Li-metal batteries

Upshifting potentials to increase reversibility

Subjects

One of the biggest hurdles to realise high-performance Li-metal batteries is the instability of Li metal towards all relevant electrolytes. Now, an approach is reported to improve Li cells’ stability by upshifting the Li electrodes’ potential to reduce their voltage gap with the electrolyte electrochemical stability windows.
