Ultrafast high-capacity NiZn battery with NiAlCo-layered double hydroxide
Abstract
High-performance, low-cost, safe and environmentally friendly batteries are important for portable electronics and electric vehicles. Here, we synthesized NiAlCo-layered double hydroxide (LDH) nanoplates attached to few-walled carbon nanotubes (NiAlCo LDH/CNT) as the cathode material of a rechargeable NiZn battery in aqueous alkaline electrolytes. The α-phase nickel hydroxide with ultrathin morphology and strong coupling to nanotubes afforded a cathode with a high capacity of ∼354 mA h g−1 and ∼278 mA h g−1 at current densities of 6.7 A g−1 and 66.7 A g−1, respectively. Al and Co co-doping is unique for stabilizing α-phase nickel hydroxide with only a small capacity loss of ∼6% over 2000 charge and discharge cycles at 66.7 A g−1. Rechargeable ultrafast NiZn batteries with NiAlCo LDH/CNT cathode and a zinc anode can deliver a cell voltage of ∼1.75 V, energy density of ∼274 W h kg−1 and power density of ∼16 kW kg−1 (based on active materials) with a charging time of <1 minute. The results open the possibility of ultrafast and safe batteries with high energy density.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
