减少对化石燃料的依赖增加了对能源储存的需求。锂离子电池已经改变了便携式电子产品，并将继续发挥重要作用，但从长远来看，它无法实现电动汽车和可再生能源电力存储等市场所需的能量密度的阶段性变化。有几种选择。这里我们描述两种：锂空气电池和锂硫电池。我们比较了锂离子、锂-空气和锂- s的能量密度，并讨论了它们的差异以及锂-空气和锂- s面临的挑战，其中许多是与材料相关的。
Reducing our dependence on fossil fuels increases the demand for energy storage. Lithium-ion batteries have transformed portable electronics and will continue to be important but cannot deliver the step change in energy density required in the longer term in markets such as electric vehicles and the storage of electricity from renewables. There are a few alternatives. Here we describe two: Li-air and Li-sulfur batteries. We compare the energy densities of Li-ion, Li-air, and Li-S and discuss their differences and the challenges facing Li-air and Li-S, many of which are materials related.
