Abstract

The Li₄Ti₅O₁₂/LiMn²O ₄ cell holds promise for safer operation of lithium-ion batteries. In this study, Li_4+xTi_5[Ai]O₁₂ anode powder was prepared by chemical lithiation of Li_1-yTi₅O₁₂ in the presence of an excess of butylithium (LiC₄H₉) in hexane solution, and Li_1-yMn₂O₄ cathode powder was prepared by chemical delithiation of LiMn₂O₄ spinel using NO₂BF₄ oxidizer in an acetonitrile medium. Thermal gravimetric analysis showed that the Li_1-yMn₂O₄ releases oxygen starting at 200°C with an overall oxygen loss of 6 wt% at 500°C, whereas the Li_4+xTi₅O₁₂ gains oxygen starting at 200°C with an overall oxygen gain of 4 wt% at 500°C. The reactivity of Li_4+xTi₅O₁₂ and Li _1-yMn₂O₄ powders in the presence of electrolyte was also investigated by differential scanning calorimetry between room temperature and 375°C. The results suggest that the Li_4+xTi ₅O₁₂ anode is thermally more stable compared with the conventional lithiated graphite anode.
