Improved Performances of Zn//MnO2 Batteries with an Electrolyte Containing Co-Additives of Polyethylene Glycol and Lignin Derivatives

. As confirmed by X-ray diffraction and scanning electron microscopy, a dominant (002) oriental dendrite-free Zn deposition was achieved on the zinc anode of the battery using 0.5% PEG200 + 0.2% QKL, and the byproducts were also reduced significantly. This study has contributed to the development of electrolyte co-additives for zinc-ion batteries.
