“…Simultaneously, there has been considerable attention on environmental issues potentially arising from the waste or manufacturing procedures of LiB [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. During the fabrication of cathodes or anodes, most industries have utilized N-methylpyrrolidone (NMP)-based slurry containing active materials, conductors, binders, and several additives [ 20 , 21 , 22 , 23 ]. However, owing to factory safety and the generated pollutants, environmental regulations in the near future concerning organic solvents will lead to new approaches to preparing LiB components [ 24 ].…”

The increase in demand for energy storage devices, including portable electronic devices, electronic mobile devices, and energy storage systems, has led to substantial growth in the market for Li-ion batteries (LiB). However, the resulting environmental concerns from the waste of LiB and pollutants from the manufacturing process have attracted considerable attention. In particular, N-methylpyrrolidone, which is utilized during the manufacturing process for preparing cathode or anode slurries, is a toxic organic pollutant. Therefore, the dry-based process for electrodes is of special interest nowadays. Herein, we report the fabrication of a cathode by a mortar-based dry process using NCM811, a carbon conductor, and poly(tetrafluoroethylene)binder. The electrochemical performance of the cathode was compared in terms of the types of conductors: carbon nanotubes and carbon black. The electrodes with carbon nanotubes showed an ameliorated performance in terms of cycle testing, capacity retention, and mechanical properties.

MXenes are an emerging class of two-dimensional transition metal carbides and nitrides with metallic conductivity and hydrophilic surfaces. The discovery of MXenes has opened new possibilities for developing advanced hybrid composites for energy storage and conversion applications. This review summarizes recent advances in developing MXene-based hybrid composites, including their synthesis, characterization, and electrochemical performance. The heterostructure of MXenes with nanocarbons, metal oxides, polymers, and other nanomaterials can overcome the limitations of pristine MXenes and lead to enhanced lithium/sodium-ion storage, pseudocapacitive performance, and electrocatalytic activity. Various fabrication techniques have been employed to synthesize MXene composites with controlled nanostructures, morphology, and interfacial properties. Characterization by microscopy, spectroscopy, and electrochemical methods has shed light on structure-property relationships in these materials. As electrode materials, properly designed MXene hybrids have achieved high specific capacity, excellent rate capability, and long-term stability. The review also discusses strategies for further improving MXene composite energy storage performance, as well as emerging applications such as thermoelectrics and photocatalysis. Continued research to understand interfacial effects and optimize MXene heterostructures holds promise for developing next-generation energy storage technologies.

Nowadays, research aimed at the development of materials with increased energy density for lithium-ion batteries are carried out all over the world. Composite anode materials based on Si and C ultrafine particles are considered promising due to their high capacity. In this work, a new approach for carbothermal synthesis of C/SiC composite mixtures with SiC particles of fibrous morphology with a fiber diameter of 0.1–2.0 μm is proposed. The synthesis was carried out on natural raw materials (quartz and graphite) without the use of complex equipment and an argon atmosphere. Using the proposed method, C/SiC mixture as well as pure SiC were synthesized and used to manufacture anode half-cells of lithium-ion batteries. The potential use of the resulting mixtures as anode material for lithium-ion battery was shown. Energy characteristics of the mixtures were determined. After 100 cycles, pure SiC reached a discharge capacity of 180 and 138 mAh g−1 at a current of C/20 and C, respectively, and for the mixtures of (wt%) 29.5C–70.5 SiC and 50Si–14.5C–35.5SiC discharge capacity of 328 and 400 mAh g−1 at a current of C/2 were achieved. The Coulombic efficiency of the samples during cycling was over 99%.
