KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

These nanodots, roughly 10 nanometers wide, were connected to the MXene’s layers by carbon materials. First, the nanodots provide additional storage capacity for lithium and speed up the charging and discharging process. Unlike graphite, MXenes can also intercalate sodium and potassium ions, notes Alshareef. —Bayhan et al.
