  6. Lithium-titanate battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-titanate_battery

    A disadvantage of lithium-titanate batteries is their lower inherent voltage (2.4 V), which leads to a lower specific energy (about 30–110 Wh/kg [1]) than conventional lithium-ion battery technologies, which have an inherent voltage of 3.7 V. [16] Some lithium-titanate batteries, however, have an volumetric energy density of up to 177 Wh/L. [1]
