The preparation of organic small-molecule cathodes is simple and low-cost; however, their low conductivity molecular dissolution are two key issues that mean energy density power performance far lower than those inorganic batteries, thus hindering practical application. To develop an effective coating technology the to obtain high-performance batteries. A general method in situ weaving all-carbon graphdiyne nanocoatings demonstrated. can be conformally weaved on particles under mild conditions so increased suppressed. After nanocoat, active mass rise 93%, delivering a higher 310 W h kg-1 previously reported, long-term stability greatly improved. Additionally, this shows great potential become crucial for fabricating batteries with close prevailing lithium-ion
