1 연소합성법Combustion method
생성물 Li[Ni1/2Mn1/2]O2 분자량 : Li : 6.94, Ni : 58.71, Mn : 54.94, O : 16 Li[Ni1/2Mn1/2]O2 : 95.77g/mol → 2g으로 만들기 = 95.77*0.021 → g 시약 Lithium Nitrate 분자량 : g/mol 분자식 : LiNO3 Nickel Nitrate 분자량 : g/mol 분자식 : Ni(NO3)2‧6H2O Manganese Nitrate 분자량 : g/mol 분자식 : Mn(NO3) 2‧6H2O Citric acid 분자량 : g/mol 분자식 : C6H8O7‧H2O 기구 Beaker, Hot Plate, Magnetic bar, Thermometer, Al Foil, Mass Cylinder, Clamp, Watch Glass, Stand 금속용액 제조 Lithium Nitrate (68.95*1.0*0.021 : g/mol) Nickel Nitrate (290.79*0.5*0.021 : g/mol) Manganese Nitrate (287.04*0.5*0.021 : g/mol) 각각의 염을 수용액(1000ml*0.021)을 1mol/L의 농도가 되게 해당양(괄호안)을 넣어준다. Citric acid 용액제조 금속염과 Citric acid의 비율을 1 : 1로 해준다. 210.14*0.021 = g을 물(1000*0.021 = 21ml)에 녹여 미리 교반하여 정치시켜 둔다.

2 실험 공정도 Mixing Metal Chelating Agent Lithium Chemical Reaction Ash
First-heated Calcination Drying at 70 ~ 80℃ Grinding

3 졸겔법(sol-gel process)을 이용한 Li(Ni1/3Co1/3Mn1/3)O2 합성
1) 시약 LiNO3, (CH3COO)2Niㆍ4H2O, (CH3COO)2Coㆍ4H2O, (CH3COO)2Mnㆍ4H2O 2) 기구 Beaker, Hot plate, Thermometer, Aluminium foil, Mass cylinder, Clamp, Stand, Magnetic bar 3) 화학양론비 ※ 최종 생성물(Li(Ni1/3Co1/3Mn1/3)O2) 2g을 합성합니다. 시 약 LiNO3 (CH3COO)2Niㆍ4H2O (CH3COO)2Coㆍ4H2O (CH3COO)2Mnㆍ4H2O 분자량 68.95 g/mol g/mol g/mol g/mol Li(Ni1/3Co1/3Mn1/3)O2 분자량 96.46 g/mol 96.46 g/mol * 0.02 = LiNO3 68.95 * 0.02 = g/mol (CH3COO)2Niㆍ4H2O * 1/3 * 0.02 = g/mol (CH3COO)2Coㆍ4H2O * 1/3 * 0.02 = g/mol (CH3COO)2Mnㆍ4H2O * 1/3 * 0.02 = g/mol 증류수 양 4가지 염(Li, Ni, Co, Mn) 1000 ml * 0.02 * 4 = 80 ml
