Mini Review on Cellulose-Based Composite Separators for Lithium-Ion Batteries: Recent Progress and Perspectives

“…In terms of mechanical strength of materials, on the one hand, some petroleum-based polymer materials can be introduced to increase the strength of the cellulose-based lithium battery through the synergy between composite materials; on the other hand, the high-strength substrate can be obtained by chemical modification of cellulose to increase the bond energy between long chains and the crystallinity of the material itself. (2) The transmission of lithium ions in the positive and negative electrodes and electrolytes of the separator substrate of a cellulose-based Liion battery. On the one hand, it is a functional modification to increase the ion transmission channel of cellulose and increase the transmission efficiency of a Li-ion battery.…”

A Review: The Development of SiO2/C Anode Materials for Lithium-Ion Batteries

“…To design an effective SiO 2 /C structure, various methods have been used, such as coprecipitation, 89,95 templateassisted, 16,75,90 hydrothermal, 28,96 sol-gel, 73 and other wet chemical methods. 48,49 Another method commonly used in the fabrication of SiO 2 /C is the mechanical method.…”

Carbon Yarn‐Ball‐Entangled SiO2 Anode with Excellent Electrochemical Performance for Lithium‐Ion Batteries

“…Various nanostructured SiO 2 have shown greatly enhanced conductivity and electrochemical reactivity compared to micrometer-sized SiO 2 . [12,[15][16][17][18][19][20][21][22][23] To alleviate the detrimental effect of pulverization, conductive shells, cages, and continuous matrices have been developed to accommodate the lattice volume variation of SiO 2 during lithiation/delithiation. [9,24] Carbonaceous materials have been extensively studied for the encapsulation of nanoscale SiO 2 , with examples such as amorphous coating layers, [13,19,25,26] continuous shells and tubes, [17,23,27,28] and hollow SiO 2 /carbon spheres.…”
