Energy consumption is a growing phenomenon in our society causing many negative effects such as global warming. There is a need for the development of new sustainable materials for energy storage. Carbons are materials derivable from biowaste that can rather easily store energy due to their high conductivity and surface area. However, their large-scale processing is challenging as derived materials can be rather heterogeneous and homogenization requires ball milling, a process that can damage carbons in the process of oxidation. Herein, we have prepared caffeine-derived noble nitrogen-doped carbon that withstands the ball milling process without significant oxidation. Additionally, it performs extraordinarily as a cathode material for lithium-ion capacitors, making it an attractive biowaste-derived alternative to commercial heavy metal cathodes.

咖啡因衍生的贵碳作为锂离子电容器的耐球磨阴极材料
能源消耗是我们社会中日益增长的现象,造成许多负面影响,例如全球变暖。需要开发新的可持续能源存储材料。碳是从生物废物中提取的材料,由于其高导电性和表面积,可以很容易地储存能量。然而,它们的大规模加工具有挑战性,因为衍生材料可能相当不均匀,并且均质化需要球磨,这一过程可能在氧化过程中损坏碳。在这里,我们制备了咖啡因衍生的惰性氮掺杂碳,它可以承受球磨过程而不会发生明显的氧化。此外,它作为锂离子电容器的阴极材料表现出色,使其成为商业重金属阴极的有吸引力的生物废物替代品。
