چکیده انگلیسی
Efficient energy storage of lithium-ion batteries plays a significant role across lots of sectors including consumer electronics, electric and hybrid electric vehicles and a smart grid accommodating intermittent renewable energy sources. Nanostructured cathode materials present fascinating opportunities for high-performance lithium-ion batteries, but intrinsic problems linked with the high surface area to volume ratios in the nanometer-range have restricted their adoption for practical applications. We demonstrate processing platform that realize high-performance nanostructured-LiNi1/3Co1/3Mn1/3O2 (NCM) layer cathode with carbon coating as a conductive additive. In this paper, we first presented a green, novel, economic and controllable chemical vapor deposition (CVD) method with sucrose as carbon source to coating NCM. Sol-gel synthesized NCM of carbon coated with optimized thickness by this formula are shown to have outstanding rate performance and robust cycle lifetime. The thickness - optimized sample of discharge capacity is as high as 104.5â¯mAh gâ1 for 10â¯C (6s). High capacity retentions of 94.29% and 94.78% after 100 cycles for 0.1â¯C, respectively. Compared with the heat evaporation method, with the CVD method has better uniformity and higher quality. This approach further improves evidently the NCM of electrochemical performance and thus promotes lithium-ion battery development technology into unprecedented regimes of operation.
