摘要 Graphite has been commercialized as a cloth of lithium ions batteries due to its considerable supply, low value and wonderful conductivity whereas the small interlayer spacing of graphite limits its software for Na+ insertion/extraction. Herein, an rising and efficient method—chain-like H2N(CH2)xNH2 locked between graphene oxide (GO) sheets to develop the interlayer spacing of graphene with enhanced stability of layered construction was demonstrated by a dehydration condensation response. The as-obtained H2N(CH2)xNH2, which may hyperlink GO (xDM-GO), reveals a lock-link construction, leading to expanded interlayer spacing, with which the wonderful Na+ storage efficiency with a excessive particular discharge capability of 158.1 mAh g−1 at 0.1 A g−1 and excellent capability retention of 82.2% at a present density of 1 A g−1 will be achieved. The consequences of interlayer spacing on Na+ diffusion coefficient and the speed functionality had been investigated, for which 0.95 nm is probably the most appropriate interlayer spacing for the Na+ insertion/extraction. The novel technique demonstrates an efficient approach to controllably tune the interlayer spacing with the improved construction stability of GO, leading to the most effective Na+ insertion/extraction conduct with the wonderful Na+ storage efficiency. © 2020
