Sigma-Aldrich Nickel(Ii) Hydroxide Battery Grade >=&

Nickel(II) hydroxide, also known as nickelous hydroxide, is an inorganic compound with the chemical formula Ni(OH)₂. It typically appears as a fine white to light green powder or crystalline solid. The material′s high electrochemical stability and capacity make it a key component in R&D activities in battery research. We offer Nickel(II) hydroxide, battery grade, ≥99.9% trace metals basis specifically desighed for research areas in rechargeable batteries with stict quality controlled parameters of low impurities (Chloride ≤ 50 ppm, NO₃ <50 ppm, Acid insoluble<50 ppm), and low water content (<2%).

Nickel(II) hydroxide, battery grade can used in battery research as an active material in rechargeable battery electrodes, particularly in nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) batteries. [1] Electroactive layered nickel hydroxides have applications supercapacitors, electrochromic devices, and electrocatalysts.[2] Ni(OH)₂‐based materials can be used as efficient electrocatalysts for water oxidation, which is a critical catalytic reaction for sustainable technologies, such as water electrolysis, fuel cells, CO₂ reduction, and metal–air batteries[3]
