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.
锂电池作为可再生能源和可持续道路运输领域的储能装置受到了广泛关注。然而,需要开发低成本、长寿命、高能量密度的锂电池,以促进其实际应用。在这里,我们报告了一种锂离子电池,其倍率性能高达 10 C,可以循环 500 次以上,工作温度范围为-20 至 55°C。估计的能量密度为 260 W h kg(-1),明显高于目前可用的锂离子电池的能量密度。
