The pursuit of new and better battery materials has given rise to numerous studies of the possibilities to use two-dimensional negative electrode materials, such as MXenes, in lithium-ion batteries. Nevertheless, both the origin of the capacity and the reasons for significant variations in the capacity seen for different MXene electrodes still …
This study reports an ambient-air-tolerant approach for negative electrode prelithiation by using 1 M lithium-biphenyl (Li-Bp)/tetrahydrofuran (THF) solution as the prelithiation reagent. Key to this …
Cathodes are the Achilles'' heels of LIBs. With a reversible capacity of 372 mAhg −1, the graphite anode has a capacity much higher than that of the cathode materials that are usually paired with it in commercial batteries small lithium-ion cells, for example, LiCoO 2 (LCO) cathodes with a usable capacity of 160 mAhg −1 and ∼60% lithium …

Organic material electrodes are regarded as promising candidates for next-generation rechargeable batteries due to their environmentally friendliness, low price, structure diversity, and flexible molecular structure design. However, limited reversible capacity, high solubility in the liquid organic electrolyte, low intrinsic ionic/electronic …
The structure of a lithium-ion battery is divided into three areas: the positive electrode, the negative electrode, and the diaphragm. The cathode material typically uses lithium ferrous phosphate (LFP), lithium cobalt oxide (LCO), lithium-nickel-cobalt-manganese oxide (LNCM), etc., while the anode material is usually graphite, and …
Silicon is a promising negative electrode material with a high specific capacity, which is desirable for commercial lithium-ion batteries. It is often blended with graphite to form a composite anode to extend lifetime, however, the electrochemical interactions between silicon and graphite have not been fully investigated.
Due to their abundance, low cost, and stability, carbon materials have been widely studied and evaluated as negative electrode materials for LIBs, SIBs, and PIBs, including graphite, hard carbon (HC), soft carbon (SC), graphene, and so forth. 37-40 Carbon materials have different structures (graphite, HC, SC, and graphene), which can meet the needs for …
The resulting suspension is referred to as the electrode slurry, which is then coated onto a metal foil, i.e. Al and Cu foils for positive electrodes and negative electrodes, respectively. On a lab scale, coating is usually achieved with comparatively primitive equipment such as the doctor blade, while at the industrial level, the state-of-the …
Surface and cross-sectional FE-SEM images of the lithium metal negative electrode after the charge/discharge cycle. Lithium utilization and the number of cycles were as follows: (a, b) 5% and 5 ...
A study of the electrochemical characteristics of titanium oxyfluoride obtained with the direct interaction of titanium with hydrofluoric acid is reported. Two materials T1 and T2 synthesized under different conditions in which some TiF3 is formed in T1 are compared. Both materials exhibit conversion-type anode properties. Based on the …
