“…In order to further improve the electrochemical performance under the premise of sustainable development, much effort has been diverted to the exploration of carbonaceous materials prepared by pyrolyzing natural biomass, such as rice straw . rice husks, coffee shells, crop stalks and sisal . Among them, the use of rice husks to extract carbon materials has made some progress.…”

Lignin carbonaceous is extracted from alkali-treated rice husk waste liquid through an acid precipitation process, and used as carbon source to prepare porous carbon in one-step and twostep methods with zinc chloride as activator at different temperatures. Then the obtained rice husk lignin-derived porous carbon has been used as anode materials for the lithium-ion batteries. After comparison, the material obtained by calcination at 500°C (one-step method) has displayed excellent cycle stability and high cycle specific capacity (469 mAh g À 1 after 100 cycles), much higher than the theoretical capacity of graphite. Good electrochemical performance is attributed to the unique porous structure of lignin-derived carbon material, which can shorten the diffusion distance of lithium ions and increase the contact area between electrode and electrolyte. This work provides an effective method to rationally utilize biomass waste materials, and supplies a new kind of biomass carbon anode materials for lithium ion batteries.

“…It can be seen from the figure that the surface functional groups varied to some extent at different carbonization temperatures. Li et al 18 reported that carbonized carbon obtained at low temperature as the electrode material exhibited low initial coulombic efficiency. Because a large number of oxygen-containing functional groups exist on the surface of carbonized carbon, they cause an irreversible reaction.…”

“…5 The stacking of carbon layers was found to enhance the cyclic stability of LIBs. According to Li et al, 18 when the carbonization temperature was 500°C, the basic carbonization of RHs was completed, and a further increase in temperature affected the formation of the layered structure of carbon.…”

In this study, we used a carbonization method to prepare biomass-based C/ SiO 2 composites from rice husks for use in lithium ion batteries. Carbonization was carried out at different temperatures in an N 2 atmosphere and a heating rate of 5°C min À1 , and the biomass-based C/SiO 2 composites were obtained. The results showed that the lithium ion batteries maintained good cycling performance under a current density of 100 mA g À1. At the same time, they had a good performance rate at different current densities. According to thermogravimetric analysis, x-ray powder diffraction patterns, Fourier transform infrared spectroscopy, Raman spectroscopy and other data for the biomass-based C/SiO 2 composites, 700°C was the optimal carbonization temperature. At this temperature, some of the carbon was carbonized, and the sp 2 hybridized carbon in the surface functional group was weakened. Simultaneously, the connection of sp 2 hybridized carbon in C=C greatly improved the properties of the materials. According to the Brunauer-Emmett-Teller results, the biomass-based C/SiO 2 composites obtained by carbonization of rice husks had micropores, which provided active sites for insertion and extraction of Li +. This method is in line with the concept of environmental protection, as carbonization is a simple process, and rice husks are by-products of processing.

“…Among the numerous carbon materials, biochar is of particular interest because of its low cost and material consistency, which can be realized from abundant and nontoxic biomass precursors . Various precursors, such as lignin, pomelo pericarp, rice husk, litchi shells, and peanut shells, have been used to prepare biochar, which was commonly carbonized at 500–900 °C under argon atmosphere and followed by acid or alkaline‐washing to remove the impurities, and then applied in LIBs as high‐capacity electrode materials . Thus, the fabrication of SiO 2 /carbon composite will be a highly attractive idea.…”

A 3D SiO2/carbon nanocomposite is fabricated from lichens successfully. By acid‐washing, nanoporous structure can be generated by removing inorganic compounds. Comparing with the SiO2/carbon nanocomposite before acid‐washing, the one after acid‐washing displays decreased electrochemical reaction resistance and better electrochemical performance as anode materials for the lithium‐ion battery. At a current density of 100 mA g−1, the hierarchical porous SiO2/carbon nanocomposite after acid‐washing shows excellent cycle stability. A high reversible capacity of 583.3 mAh g−1 can still be obtained after 100 cycles, which is much higher than the theoretical capacity of graphite.
