摘要: Abstract An examination has been made of the effectiveness ethylene carbonate(EC)/2-methyltetrahydrofuran(2-MeTHF) solvents incorporating LiAsF6 as solute electrolytes in secondary lithium batteries. From —10 to 30 °C, conductivities EC/2-MeTHF are higher than those 2-MeTHF and EC/propylene carbonate (PC). For lithium-on-lithium cycling a half cell, FOM (figure merit) value 2.2 2.7 times that EC/PC. A coin cell Li/amorphous V2O 5-P2O5 with clearly exhibits capacity longer cycle life cells or It is concluded promising electrolyte system for battery applications.
