“…Interestingly, all the prepared carbonecous samples displayed diffused charge/discharge profiles, though the specific surface areas were notably lower in comparison to the graphene as well as turbostratic carbon derived from the biomass resources. [35][36][37][38][39][40][41] Our results on the BET surface area as well as the charge/discharge profiles were consistent with the results reported by Cheng et al 42 on graphenelike graphite (GLG)-based lithium anodes; however, a notably higher Coulombic efficiency was observed in contrast to their results. For instance, the first charge/discharge results of BCA-1000, BCA-1200, and BCA-1400 were observed as 627/ 435 mA h g −1 (Coulombic efficiency, 69.4%), 675/518 mA h g −1 (Coulombic efficiency, 76.7%), and 721/596 mA h g −1 (Coulombic efficiency, 82.4%), and these values were notably higher in comparison to the GLG-based anodes.…”

Biomass-derived carbon (BC) has attracted extensive attention as anode material for lithium ion batteries (LiBs) due to its natural hierarchical porous structure and rich heteroatoms that can adsorb Li + . However, the specific surface area of pure biomass carbon is generally small, so we can help NH 3 and inorganic acid produced by urea decomposition to strip biomass, improve its specific surface area and enrich nitrogen elements. The nitrogen-rich graphite flake obtained by the above treatment of hemp is named NGF. The product that has a high nitrogen content of 10.12% has a high specific surface area of 1151.1 m 2 g À 1 . In the lithium ion battery test, the capacity of NGF is 806.6 mAh g À 1 at 30 mA g À 1 , which is twice than that of BC. NGF also showed excellent performance that is 429.2 mAh g À 1 under high current testing at 2000 mA g À 1 . The reaction process kinetics is analyzed and we found that the outstanding rate performance is attributed to the large-scale capacitance control. In addition, the results of the constant current intermittent titration test indicate that the diffusion coefficient of NGF is greater than that of BC. This work proposes a simple method of nitrogen-rich activated carbon, which has a significantly commercial prospect.

“…[21] In addition, low specific surface area could improve coulombic efficiency. [22] The thermogravimetric (TG) analysis was carried out to study the carbon content of the CuO/C/NF nanocomposites ( Figure 6b). A weight loss of about 2.3 % is observed below 300°C on the TG curve, which mainly corresponds to the loss of free water and physically adsorbed water.…”

At present, the high theoretical specific capacity CuO-based anodes are considered as a potential host for lithium-ion batteries (LIBs). Unfortunately, the intrinsic poor conductivity of metal oxide and the huge volume expansion during the cycling caused serve capacity fading and unsatisfactory cycling stability. Here, a porous free-standing octagonal flower-like copper oxide (CuO)/carbon(C)/nickel foam (NF) multilevel structure is synthesized. The design of carbon-coated ensures excellent mechanical strength, chemical stability and conductivity of nanocomposite, which effectively prevent the collapse and corrosion of the active material during cycle. In addition, 3D interconnected structure shortened the transmission distance of electrons and Li + , improving the ability of fast charge and discharge. The CuO/C/NF electrode exhibits high performance in cycling as the anode material for LIBs. The initial charge/ discharge specific capacity of the octagonal flower-like CuO/C/ NF electrode is 871.1 mA h g À 1 and 916.06 mA h g À 1 at 0.5 A g À 1 , respectively. It achieves an outstanding discharge specific capacity of 505 mA h g À 1 at 2 A g À 1 after 800 cycles. This work combines CuO with a conductive matrix (carbon) and a 3D porous NF, effectively enhancing the electrochemical properties of CuO, which is of certain significance to the further research.
