Electric double-layer capacitors (EDLC) exhibit very high storage energy density compared with other capacitors, but their inner resistance is rather higher and output voltage lower.

在储能电容器中，双电层电容器的储能密度特别高，但其内电阻大，且元件的输出电压低。

The material's large surface area, flexibility, low density, and high conductivity also make it compelling for energy storage.

材料的巨大表面积、弹性、低密度以及高导电性使得它也可以用于储存能量。

In this scenario, pellets stand out because they are easy to handle natural products. They require little storage space and have high energy density.

在这种情况下颗粒脱颖而出，因为它们是很容易处理的天然产品。它们存储空间小并且具有高能量密度。

Our ability to store electricity in batteries is improving, but current low energy density makes batteries an inefficient choice for large-scale storage.

The automakers need to come out with battery packs that can retain a greater percentage of their storage capacity for longer, cost half as much, and have improved energy density, so that they can serve many driving cycles.
