2.1.Sol–gel (SG) method
Li1.05Ni1/3Co1/3Mn1/3O2 cathode material was synthesized by the citric acid sol–gel method [31] in following manner.Stoichiometric amounts of Li(CH3COO)•2H2O,Mn(CH3COO)2•4H2O,Ni(CH3COO)2•4H2O,and Co(CH3COO)2•4H2Owere dissolved in distilled water.Citric acid was used as a chelating agent.The solution pH was adjusted to 7.0 with ammonium hydroxide.The solution was heated at 70–80 ◦C until a transparent sol was obtained.The
resulting gel precursor was dried at 120 ◦C for 4 h in air and followed with decomposition at 450 ◦C for 8 h to remove the organic contents.The decomposed powders were ground by ball milling (Spex 8000 Mixer/Mill) with stainless steel balls for 2 h and sintered at 850 ◦C in air for 12 h.The heating and cooling rates of the
powder were 4 ◦C and 2 ◦Cmin−1,respectively.
2.2.Co-precipitation (CP) method Li1.05Ni1/3Co1/3Mn1/3O2 cathode material was synthesized by co-precipitation method from Ni–Co–Mnmixed hydroxide precursor [17,24].The precursor (Ni1/3Co1/3Mn1/3)(OH)2 was prepared
by dissolving stoichiometric amounts of Ni(CH3COO)2•4H2O,Co(CH3COO)2•4H2O and Mn(CH3COO)2•4H2O in distilled water (cationic ratio of Ni:Co:Mn = 1:1:1) and the concentration of the total metal acetate was 2mol L−1.The aqueous solution was precipitated by adding LiOH (1 M)/NH4OH (3M) along with continued stirring.The solution was maintained at 50 ◦C for 24 h and the pH was controlled to 10–11.A green brown mixed hydroxide was precipitated.
After filtering and washing,the hydroxide precipitatewas dried at 120 ◦C for 24 h to remove the adsorbed water.Then,the obtained precursor was mixed with required amount of LiOH using a ball mill (Spex 8000 Mixer/Mill) and the powder was pressed into pellets.The pellets were initially heated to 400 ◦C for 6 h in air and then reground.Pellets were remade and subsequently sintered at 900 ◦C for 12 h in air in amuffle furnace.Heating up speed was fixed to 4 ◦Cmin−1 and cooling down speed was fixed to 2 ◦Cmin−1

2.1、溶胶-凝胶法(SG)法
用溶胶-凝胶法按以下方式以柠檬酸合成Li1.05Ni1/3Co1/3Mn1/3O2阴极材料：将化学计量的Li(CH3COO)•2H2O,Mn(CH3COO)2•4H2O,Ni(CH3COO)2•4H2O溶解在蒸馏水中.柠檬酸被用作螯合剂.溶液pH用氨水调整到7.0.将该溶液在70-80◦C下加热直到获得一个透明溶胶.产物凝胶的前体物质在空气中、120◦C下干燥4小时,接着在450◦C下热解8小时以减少有机物含量.热解得到的粉末用球磨研磨机(Spex 8000研磨机)和不锈钢球研磨2小时,然后在空气中、850◦C下烧结12小时.加热和冷却速率分别为4◦C min−1和2 ◦Cmin−1.
2.2.联合沉淀法
用联合沉淀法按以下方式以Ni-Co-Mn前体合成Li1.05Ni1/3Co1/3Mn1/3O2阴极材料[17,24].前体(Ni1/3Co1/3Mn1/3)(OH)2通过用蒸馏水溶解化学计量的Ni(CH3COO)2•4H2O、 Co(CH3COO)2•4H2O、Mn(CH3COO)2•4H2O,镍、钴(4H2O••4H2O体积和锰(体积4H2O•在蒸馏水(阳离子比Ni:Co:Mn= 1:1:1),金属醋酸盐的浓度的是2mol L−1.水溶液加入LiOH(1调制系数)/ NH4OH (3调制系数)来沉淀并持续搅拌.溶液在50◦C下保温24小时,pH值控制在10-11之间.生成黄绿色氢氧化物沉淀.过滤、洗涤之后,氢氧化物在120◦C下干燥24小时除去吸附水.然后,所得到的前体掺适量的LiOH使用球磨研磨机(Spex 8000研磨机)研磨,使粉末被压成小球.小球在空气中400◦ C下加热6小时,然后重新研磨.重制小球,然后在空气中、900◦C下用隔焰炉烧结12小时.加热速度固定和冷却速度分别在4◦Cmin−1和2 ◦Cmin−1.
