1. PERHITUNGAN PENCAMPURAN BAHAN BAHAN
1.1 Menghitung massa bahan LTO
4LiOH.H2O + 5TiO2 Li4Ti5O12 + 3H2O
1.2.Menghitung massa bahan NaLiTi3O7
LiOH.H2O + 3 TiO2 + ½ Na2CO3 NaLiTi3O7 + ½ CO2 + ½ H2O + H2
2 Li + TiO2 + e- LixTiO2
Berat atom Ti = 47,867
Berat atom O = 15,999
Berat atom TiO2 = 47,867 + 2(15,999)
= 79,856 x 10-3
Specific capacity = (N x F ) / (berat atom)
Dimana : N= valensi atom
F = Konstanta Faraday (96485 colomb/mol) (26,801 Ah/mol)
Specific capacity = (1 x 26,801) / (79,865 x 10-3)
= 335,57 mAh/g
