Solid-state synthesis and electrochemical performance of Li4Ti5O12/graphene composite for lithium-ion batteries

Posted on Leave a commentPosted in Neware Testing News

a b s t r a c t Homogeneous Li4Ti5O12/graphene composite is prepared via an in-situ solid state reaction, after carbon pre-coating has been carried out. Its microstructure is compared with the materials prepared by a similar way, but without carbon coating. The results reveal that the carbon coating not only effectively confines aggregation and […]

Highly durable organic electrode for sodium-ion batteries via a stabilized α-C radical intermediate

Posted on Leave a commentPosted in Neware Testing News

Abstract It is a challenge to prepare organic electrodes for sodium-ion batteries with long cycle life and high capacity. The highly reactive radical intermediates generated during the sodiation/desodiation process could be a critical issue because of undesired side reactions. Here we present durable electrodes with a stabilized α-C radical intermediate. Through the resonance effect as […]
