Biomass-based porous carbon has attracted much attention of researchers due to its wide range of raw materials, low cost, and other advantages. It has been also widely used in energy storage devices such as lithium-ion batteries. The carbonization process and final morphology of biomass are indirectly affected by the surface modification and structure optimization of the original biomass. The focus of this study is to prepare porous carbon, which can be used as an electrode material of a lithium-ion battery by surface modification and structure regulation of biomass pretreatment. In this study, the method of H2O2-assisted hydrothermal treatment was used to prepare a kind of bagasse based porous carbon materials that can be used in lithium-ion batteries. The reaction process of H2O2 and bagasse under hydrothermal conditions was explored and described. The results showed that H2O2 promoted the hydrolysis and oxidation of lignocellulose in bagasse and the small molecules obtained from lignocellulose hydrolysis under hydrothermal conditions would be repolymerized to form carbon spheres. The prepared carbon material was applied to the lithium-ion battery. Under a current density of 0.1 A g–1, the specific capacity of 891 mAh g–1 in the first cycle was displayed, and a specific capacity of 453 mAh g–1 was maintained after 150 cycles. At the same time, it showed a good rate performance. After 10 cycles at current densities of 0.1, 0.2, 0.5, 1, 2, and 5 A g–1, the specific capacities of 545, 421, 307, 245, 195, and 133 mAh g–1 were obtained. All the raw materials and products used in this experiment are harmless to the environment, which has certain guiding significance for the structural regulation and green synthesis of lignocellulosic biomass-derived carbon materials.

“…We noticed that the charge/discharges curve of the full cell (Figure 7g) is different from the curve of CoNiSe 2 /NC composites in a half-cell, which is a result of the voltage difference between CoNiSe 2 /NC and LiFePO 4 . 48 As shown in Figure 7h, once the full batteries are connected in parallel, they can power the LED lights for ∼5 min, suggesting potential use in practical systems. Due to the excellent cycling and rate performance of the CoNiSe 2 /NC-700 composite, we performed an in situ XRD test during the first charge/discharge cycle, so as to investigate its lithium storage mechanism.…”

“…We used commercial LiFePO 4 as the cathode and CoNiSe 2 /NC-700 as the anode to assemble a full cell, which is tested within a voltage range of 0.5–4.2 V. As shown in Figure f, the initial charge/discharge capacity is 2445.7/1574.7 mA h g –1 at 0.1 A g –1 , and the discharge specific capacity is still 568.7 mA h g –1 after 100 cycles with a good Coulombic efficiency around 98%. We noticed that the charge/discharges curve of the full cell (Figure g) is different from the curve of CoNiSe 2 /NC composites in a half-cell, which is a result of the voltage difference between CoNiSe 2 /NC and LiFePO 4 .

Lithium-ion batteries (LIBs) have been widely used for portable electronics and electric vehicles; however, the low capacity in the graphite anode limits the improvement of energy density. Transition-metal selenides are promising anode material candidates due to their high theoretical capacity and controllable structure. In this study, we successfully synthesize a bimetallic transition-metal selenide nanocube composite, which is well embedded in a nitrogen-doped carbon matrix (denoted as CoNiSe2/NC). This material shows a high capacity and excellent cycling for Li-ion storage. Specifically, the reversible capacity approaches ∼1245 mA h g–1 at 0.1 A g–1. When cycled at 1 A g–1, the capacity still remains at 642.9 mA h g–1 even after 1000 cycles. In-operando XRD tests have been carried out to investigate the lithium storage mechanism. We discover that the outstanding performance is due to the unique CoNiSe2/NC nanocomposite characteristics, such as the synergistic effect of bimetallic selenide on lithium storage, the small particle size, and the stable and conductive carbon structure. Therefore, this morphology structure not only reduces the volume change of metal selenides but also produces more lithium storage active sites and shortens lithium diffusion paths, which results in high capacity, good rate, and long cycling.
