reaction: Co→CO2++2e, Ni→Ni2++2e(1) Cathodic reaction: 2H2O+2e→H2↑+2OH-(2) pH value of the solution near cathode increased during the electrolysis process, and the precipitation of Ni2+, CO2...Synthesis of LiCoxNi1-xO2 cathode materials from electrolysis Co-Ni alloys YE Mao(叶 茂)1, WEI Jin-ping(魏进平)1, CAO Xiao-yan(曹晓燕)2, ZHAI Jin-ling(翟金玲)1, WANG Xiao-yu(王晓宇)1, SUN Xin(孙 欣)1......
in terms of the two main factors that control this property. Firstly, an increase of the cathodic polarization has an equalizing effect on the primary current distribution and so increases the throwing..., pH and temperature on the potentiodynamic cathodic polarization curves, cathodic current efficiency and throwing index, as well as the electrical conductivity of these baths. The optimum conditions......
