Biomass-based diatomite coating to prepare a high-stability zinc anode for rechargeable aqueous zinc-ion batteries

Engineering Interphasial Chemistry for Zn Anodes in Aqueous Zinc Ion Batteries

“…At present, many inorganic materials (e.g . , ZnF 2 , CaCO 3 , TiN nanosheets, Al 2 O 3 , diatomite, MXene, polyphosphoric), and organic materials (e.g . , MOF, − polyacrylonitrile, and guar gum) have been used to coat the zinc anode to inhibit the growth of zinc dendrites.…”

“…The SEI constructed on the anode by the physical coating method can effectively inhibit the growth of zinc dendrites. At present, many inorganic materials (e.g., ZnF 2 , 80 CaCO 3 , 81 TiN nanosheets, 82 Al 2 O 3 , 83 diatomite, 84 MXene, 85 polyphosphoric 86 ), and organic materials (e.g., MOF, 87−91 polyacrylonitrile, 92 and guar gum 93 ) have been used to coat the zinc anode to inhibit the growth of zinc dendrites.…”

Stabilizing Zinc Anode through Ion Selection Sieving for Aqueous Zn-Ion Batteries

“…The negative-to-positive electrode capacity (N/P) ratio is 4.2, and a lower N/P ratio will favorably enhance the energy density of the battery (Supporting Information: additional N/P ratio details). − The NB@Zn and CB@Zn electrodes exhibit characteristic discharge/charge curves and achieve high discharge capacities of 96.7 and 70.4 mAh g –1 after 1000 cycles, respectively, which also shows excellent performance in many excellent published articles (The list refers to reports from Table S1). ,,− For the bare Zn battery, the discharge capacity of the full cell is low because of severe Zn dendrites and side reactions. The CE plots show that the bentonite electrodes exhibit a more consistent charging and discharging process than that of the bare Zn anode (Figure b).…”
