199.1 μWh cm−2at power densities of 312.4 and 6471 μW cm−2, respectively. Moreover, additive-free Ti3C2MXene inks were prepared via a divalent cation-assisted gelation strategy, and the 3D-printed Ti3C2MXene was used in ZHSCs33(Fig.3c). The Ti3C2MXene electrodes were ...
MXene can be a kind of ideal material to fabricate the protective layer of the Zn anode due to its feasible thickness, strong intermolecular interaction with hydrophile, and zincophile characteristics. For example, Niu and co-workers developed a simple strategy to assemble the MXene layer on the...
