AbstractThis paper reports physical and electrochemical properties of a solid electrolyte for lithium batteries formed by doping a plastic crystal solvent, succinonitrile, with lithium bioxalato borate (LiBOB). Thermal properties, solubility limits, conductivity, compatibility with lithium, and range of electrochemical stability have been studied. Succinonitrile doped with 4 mol % LiBOB is a solid at room temperature and melts near 50°C. Electrochemical cells employing either LiFePO₄ or Li₁.₂Mn₀.₄Ni₀.₃Co₀.₁O₂ as the active cathode material and lithium metal as the anode were evaluated. This solid electrolyte showed excellent performance when combined with a LiFePO₄ cathode, delivering a reversible discharge capacity of ~142 mAh g⁻¹ with very good capacity retention. However, with the Li₁.₂Mn₀.₄Ni₀.₃Co₀.₁O₂ cathode, the cell’s capacity retention was not as good exhibiting a discharge capacity that decreased from 194 mAh g⁻¹ in the first cycle to 149 mAh g⁻¹ at 20th cycle.
