Enhanced specific energy in fast-charging lithium-ion batteries negative electrodes via Ti-O covalency-mediated low potential

Abstract Developing lithium-ion batteries with high specific energy and fast-charging capability requires overcoming the potential-capacity trade-off in negative electrodes. Conventional fast-charging materials (e.g., Li4Ti5O12, TiNb2O7) operate at high potentials (>1.5 V vs. Li+/Li) to circumven...
