Carbonyls: Powerful Organic Materials for Secondary Batteries

The application of organic carbonyl compounds as high performance electrode materials in secondary batteries enables access to metal‐free, low‐cost, environmental friendly, flexible, and functional rechargeable energy storage systems. Organic compounds have so far not received much attention as potential active materials in batteries, mainly because of the success of inorganic materials in both research and commercial applications. However, new requirements in secondary batteries such as flexibility accompanied with low production costs and environmental friendliness, in particular for portable devices, reach the limit of inorganic electrode materials. Organic carbonyl compounds represent the most promising…
