“…In other words, the battery lifetime becomes longer or more durable. Lithium battery cathodes subjected to calendering have better electrochemical performance, stability, and cycling performance [13]. In the test from cycle 1 to 50, each battery has a low-capacity drop, which is 5.63% for 30% calendered batteries, then 4.88% for 45% calendered batteries, and 4.18% for 60% calendered batteries.…”

“…Lithium Nickel Manganese Cobalt Oxide (LiNi x Mn y Co z O 2 or NMC) is one of the most commonly used cathode materials in lithium-ion batteries [12]. The combination of nickel-manganese-cobalt elements can make the battery have high performance, such as high capacity, high heat and current stability, and long cycle life [13]. LiNi 0.8 Mn 0.1 Co 0.1 O 2 (NMC 811) cathode is an NMC cathode composition that can produce high capacity, making it suitable for application in equipment that requires high energy such as electric vehicles [14], [15].…”

The need for energy in various activities around the world is increasing. Batteries come as an important energy solution, among others, for various applications, such as electric vehicles, mass storage for utilities, gadgets, etc. Lithium-ion batteries that are able to produce superior performance are needed. The battery cathode is an important key to the performance of lithium-ion batteries. The battery cathode fabrication factor is one that affects the quality of the battery produced. The thickness of the coating material will determine the amount of active material contained in the cathode, while the calendering process is needed to compress the material in the cathode so that the lithium-ion transfer process in the battery can run more effectively. Based on the research results, the thicker the coating material on the cathode, the greater the capacity value produced. With a coating thickness of 300 µm, the resulting capacity reaches 180 mAh/gr. However, in the life cycle and rate capability tests, the performance stability is not better than the thickness of 100 µm and 200 µm. As for the calendering level, the battery with an optimum decrease in dry thickness is able to have the best performance in terms of capacity, life cycle, and rate capability.

LiNi1/3Mn1/3Co1/3O2 (NMC 111) materials show promise as cathodes for lithium‐ion batteries (LIBs). However, their widespread use is hampered by various technical challenges, including rapid capacity fading and voltage instability. The cathode materials synthesized using the combustion method were annealed at various temperatures ranging from 650 to 900 °C for 24 h. In this study, we identified an optimal annealing temperature of 750 °C for LiNi0.3Mn0.3Co0.3Ti0.1O2 (NMCT) materials. NMCT‐750 exhibits an initial discharge capacity of about 140.1 mAh g−1 and retains the capacity of 91 % after 30th cycles. The good performance of NMCT‐750 is directly attributed to reduced cation mixing and the establishment of a stable structure with small particle sizes. In contrast, higher annealing temperatures (850 °C) lead to a rapid increase in primary particle size and result in poor cycling stability. Therefore, NMCT‐750, annealed at 750 °C, holds great potential as a cathode material for the next generation of LIBs.

Regulating the distribution of surface elements in lithium‐rich cathode materials can effectively change the electrochemical performance of cathode materials. Considering that the enrichment of Mn element on the surface is the main reason for the irreversible phase transition and dissolution of its surface structure, which in turn is the main reason for performance degradation. Based on the molten salt‐assisted sintering method, a lithium rich cathode material with surface rich Ni and Co is designed and prepared. The surface enrichment of Ni and Co effectively reduces the dissolution of Mn, promotes the occurrence of irreversible collapse of surface structure from layered phase to rock salt phase on the material surface, improves the stability of surface crystal phase structure, and improves the cycling stability of positive electrode materials. Notably, after 500 cycles at 1 C current density, the discharge‐specific capacity attained 189.8 mAh g −1, with a capacity retention rate of 88.9%, indicating a 42.1% improvement in capacity retention. Molten salt treatment is widely used in the modification of positive electrode materials. The research work will provide new ideas for improving the stability of lithium rich materials and promoting their commercial applications.
