Abstract:

For a long time, carbon has been an ideal material for various electrochemical energy storage devices and a key component in electrochemical energy storage systems due to its advantages of rich surface states, easy tenability, and good chemical stability. Stable and high-performance carbon materials can support future applications of high specific energy electrodes. Herein and for the first time, we have designed nitrogen-doped carbon hollow containers using oleylamine-coating TiO2 mesocrystals as a precursor with a high specific surface area of 1231 m(2) g(-1). When applied as an anode for lithium-ion storage, a reversible capacity of 774.5 mA h g(-1) is obtained at a rate of 0.5 A g(-1) after 200 cycles. Meanwhile, at an even higher rate of 2 A g(-1), a capacity of 721.1 mA h g(-1) is still achieved after 500 cycles. Moreover, the carbon containers remain structurally intact after a series of cycles. This may be attributed to the nitrogen atoms doped on the carbon surface that can absorb multiple lithium ions and enhance the structural stability. These results provide technical support for the development of high specific energy electrode materials. (C) 2022 Elsevier Inc. All rights reserved.
