Phys.org  October 4, 2022 Accurate assessment of the reversibility of electrodes is crucial for battery performance evaluations. However, it is challenging to acquire the true reversibility of the Li anode in lithium-metal batteries, mainly because an excessive amount of Li is commonly used. An international team of researchers (China, USA – UC San Diego, University of Chicago) proposed an analytic approach to quantitatively evaluate the reversibility of practical lithium-metal batteries. They identified key parameters that govern the anode reversibility and subsequently established their relationship with the cycle number by considering the mass of active and inactive Li of the cycled […]
