Li‐ion batteries (LIBs) are currently the most preferred energy storage devices in portable applications. Recent surge in the production of electric vehicles in the wake of the current global warming scenario has strongly increased the demand for LIBs, thereby reinforcing the need for new battery chemistries as well as making the existing production chain more efficient and sustainable. Several new technologies are explored to achieve these goals. Among them, plasma technology has the potential to simplify the synthesis and modification of battery materials, enable ‘dry’ and ‘green’ processing that eliminate the need for solvents that are often toxic, expensive, flammable, and energy‐intensive. In this review, we have attempted to provide an overview of state‐of‐the‐art (scientific) research and development with respect to the application of plasma‐based processes in the synthesis and modification of materials for battery components. We have explored various applications wherein plasma‐based processes have been demonstrated in the processing of electrode materials, electrolytes, and separators in addition to the recent developments in the context of solid‐state and flexible batteries. Our analysis shows that plasma‐based technologies are slowly but steadily gaining attention in these areas. Several technical and conventional issues remain, which require innovations at the conceptual as well as engineering levels. Technical issues include the selection of appropriate plasma type and precursors, plasma density, selectivity, and a preferable shift from vacuum to atmospheric conditions. The conventional issues include the practical difficulties in converting or adapting the assembly lines to plasma‐based technology. From a business perspective, all that matters is the cost per mAh g−1 of energy produced, for which, unfortunately, we do not have sufficient quantitative data yet with regard to the materials processed by plasma‐based technologies. However, the battery manufacturing sector is now open for innovations like never before. Therefore, it remains to be seen how plasma technologies embrace this opportunity and penetrate the battery production sector, where the key parameters are efficiency and cost‐effectiveness. Would ‘giving it the plasma touch’ bring added value to the battery manufacturing processes? That is the question we try to address in this review.

“…The cathode materials for lithium-ion batteries like layered structure LiMO 2 (M=Co, Ni and Mn), Spinel structure LiMn 2 O 4 and Olvine structure LiMPO 4 (M=Fe, Co, Ni and Mn) were mostly studied in world wide [4][5][6][7][8]. In general, the spinel structure LiMn 2 O 4 was taken as an attractive candidate for the cathodes of lithium-ion batteries due to its low cost, easy preparation and high environmental acceptability than other LiCoO 2 , LiNiO 2 and LiFePO 4 cathode materials [9].…”

“…The manganese-based material LiMn 2 O 4 is being considered one of the most promising cathode materials owing to its low cost, abundance, environmental friendliness, nontoxicity, and high capacity [8][9][10]. Various synthesis techniques have been employed to prepare LiMn 2 O 4 cathode materials, such as solid-state reaction [11,12], hydrothermal synthesis [13][14][15], microwave synthesis [16], sol-gel processing [17,18], co-precipitation [19,20], and so on. Among these techniques, a novel solution combustion synthesis (SCS) method, based on a highly exothermic and self-sustaining reaction, has been attracting particular interest because it allows homogeneous doping of elements in trace amounts, and yields nano-sized particles with high specific areas [21,22].…”

Single-phase, high-purity nanosized LiMn 2 O 4 powders, which are employed as cathode materials for lithium-ion batteries, were produced by solution combustion synthesis using glycine, sucrose, and nitrate, followed by calcination. Phase structure and morphology of the powders were characterized by X-ray diffraction and scanning electron microscopy. The electrochemical performance was measured by galvanostatic charge-discharge cycling in a voltage range of 3.2-4.4 V. The analysis of yield, morphology, and electrochemical performance mainly focused on the influence of different glycine/sucrose ratios. Compared to the sample obtained using 100% glycine, the yields of powders obtained by adding sucrose to the fuel were remarkably improved, from around 50% to over 90%. The highest discharge capacity at 1 C was obtained for the sample with 2% added sucrose, which retained a capacity of 116.6 mAh/g after 80 cycles.
