Nickel hydroxides and related materials: a review of their

The exfoliation of layered structures, in general, such as perovskites, hydroxyl double salts and LDHs, has been studied in more detail []. Just as the properties of graphene are wholly different than those of graphite, the properties of exfoliated nickel hydroxide can be quite different from those of either α - or β -Ni(OH) 2 [ 102 ].

Controlling electrochemical growth of metallic zinc

As the metal covers the electrode surface, the front interface/phase between the metal and the electrolyte instead plays a pivotal role directing the growth mode. The second set of solutions aims at controllably creating an artificial SEI (ASEI) that exhibits desirable properties (see the green block).

Zeng et al. [] report synthesis of nanosheets of various metal chalcogenides such as MoS 2, WS 2, TiS 2, TaS 2 and ZrS 2 by electrochemical Li-intercalation and subsequent exfoliation in water. Li-intercalation is carried out by controlled galvanostatic discharge at 0.05 mA current density in a standard battery test system with the layered bulk material as the cathode and the Li-foil as the anode.
