“…Thirdly, the surface alkali content for high-nickel cathode materials is high, and it easily reacts with moisture and carbon dioxide in the air. A high alkaline content can aggravate a side reaction with the electrolyte and seriously affect the electrochemical properties of the high-nickel samples [6].…”

LiNi0.8Co0.1Mn0.1O2 (NCM811) has attracted extensive attention as a promising cathode of lithium-ion batteries (LIBs) in next-generation electric vehicles, as the NCM811 sample possesses a high energy density and a price advantage. In this work, NCM811 was modified with an Al(PO3)3 precursor using the dry ball milling method followed by heat treatment to enable commercial development both at room temperature and a higher temperature. Compared with the unmodified NCM811 sample with the capacity retention of 68.70%, after Al(PO3)3 modification, the NCM811 sample heated to 500 °C exhibited a super capacity retention ratio of 93.88% after 200 charging–discharging cycles with the initial discharge capacity of 178.1 mAh g−1 at 1 C. Additionally, after Al(PO3)3 modification, the NCM811 sample heated to 500 °C showed much improved rate performance compared to bare NCM811 at the current density of 5 C. The enhanced electrochemical performance after cycling was due to the decreased charge transfer resistance and increased Li+ transmission, which were confirmed via electrochemical impedance spectra (EIS). The NCM electrodes showed improved structural stability as layered structures after Al(PO3)3 modification, consistent with the improved cycling performance. This work revealed that LiNi0.8Co0.1Mn0.1O2 material with phosphide coating can be constructed using a simple ball milling method, which is feasible for obtaining high-performance electrode materials.

Continuous renewable technologies can only be adequate when coupled with efficient nanomaterial based energy storage systems. These gadgets can reliably provide electricity even on overcast days or at night. To power the majority of consumer devices regardless of environmental conditions, the battery business is thriving. Among electrochemical energy storage devices (EESD), lithium-ion batteries (LiBs) have been a popular option for many eras. Even LiBs with a greater energy density (ED) and strong charge-discharge behaviour still have safety, durability problems and are expensive. Thus, various battery technologies, have attracted the attention of scientists all around the globe. However, both main and secondary batteries are used to power numerous electronic equipment. Focus will be placed on optimising battery performance, cost, and mass manufacturing in order to commercialize the batteries. This chapter will explore several battery kinds with different nanomaterials and their characteristics. Extensive details will be provided on the regulating criteria for battery performance, its fundamental design, and the operating principle of energy storage. In addition to diverse electrodes and electrolytes, this chapter provides information on the benefits and downsides of various batteries as well as ideas for future advancements in smart electronics battery systems.
