A high-rate long-life Li₄Ti₅O₁₂/Li[Ni_0.45Co_0.1Mn_1.45]O₄ lithium-ion battery

摘要

Lithium batteries are receiving considerable attention as storage devices in the renewable energy and sustainable road transport fields. However, low-cost, long-life lithium batteries with higher energy densities are required to facilitate practical application. Here we report a lithium-ion battery that can be cycled at rates as high as 10 C has a life exceeding 500 cycles and an operating temperature range extending from ?20 to 55 °C. The estimated energy density is 260 W h kg?1, which is considerably higher than densities delivered by the presently available Li-ion batteries.. ? 2011 Nature Publishing Group, a division of Macmillan Publishers Limited.
