Due to the large reversible capacity, high operating voltage and low cost, layered ternary oxide cathode materials LiNixCoyAl1−x−yO2 (NCA) and LiNixCoyMn1−x−yO2 (NCM) are considered as the most potential candidate materials for lithium-ion batteries (LIBs) used in (hybrid) electric vehicles (EVs). However, next-generation long-range EVs require a high specific capacity (around 203 mAh•g-1 at 3.7V) at the cathode active material level, which is not provided with current commercially layered ternary oxide cathodes. Increasing the operating voltage is an effective method to improve the specific capacity of the cathode and the energy density of the battery, but the high operating voltage also causes a lot of problems, such as cation mixing and phase transformation, electrolyte decomposition, transition metal dissolution and microcracks. So far, researchers have carried out a lot of works to solve these issues. Surface coating, element doping and the design of electrolytes have been proved to be effective solutions. In this review, the failure mechanisms and modification methods of high-voltage layered ternary oxide cathode materials are summarized, which could provide valuable information to the research of high-voltage layered ternary oxide cathode materials in basic science and industrial production.

Layered ternary oxide cathode materials LiNi x Mn y Co1–x–y O2 (NMC) and LiNi x Co y Al1–x–y O2 (NCA) (referred to as ternary cathode materials, TCMs) with large reversible capacity, high operating voltage as well as low cost are considered as the most potential candidate materials for high energy density lithium ion batteries (LIBs) used in hybrid electric vehicles and electric vehicles (EVs). However, next-generation long-range EVs require an energy density of 800 W h kg–1 at the cathode level, which cannot be obtained using the commercially available TCMs. Developing high-voltage TCMs is a promising solution to enhance energy density of LIBs. Nonetheless, the capacity decay, poor long-term cycle life and microcrack at high operating voltage have limited their practical applications. In this paper, the development of the high-voltage TCMs is reviewed from degradation mechanism, cathode electrode modification, electrolyte design, solid state electrolytes and so on. The critical factors, recent progress and perspectives that improve the performance of TCMs with high-voltage operation are reviewed, which could provide important information and precautions to the practical use of these cathode materials under high operating voltage.

“…There are four processes for preparation of synthetic rutile, normally including reduc tion corrosion process, hydrochloric acid leaching pro cess, selective chlorination process and electrothermal process. Researches indicate that [1][2][3][4][5], reduction corro sion process demands high standard of raw materials, hy drochloric acid leaching process has a more rigorous re quirement on equipments, its hydrochloric acidrecycling costing high, and the selective chlorination process is not appropriate for processing titanium concentrate whose calcium and magnesium content is high, and its tail gas recovery is troublesome. The electrothermal process which is consist of electric furnace reduction smelting of imenite and rotary kiln oxidation smelting of high tita nium slag procedures, is Chinese unique production method characterized by less pollution and simple opera tion.…”

Due to its special nature of microwave heating, the reaction processes of high dielectric loss materials under microwave field draw more and more attention. This work attempts to figure out microwave oxidation process of high titanium slag. Based on a through anal ysis, it can be concluded that high titanium slag phase transformation process under microwave field can be divided into four stages: (i) crystallization of amorphous Fe, Mg, and Ti oxides, (ii) decomposition of Fe 0.5 Mg 0.5 Ti 2 O 5 , (iii) oxidation of (Mg 0.15 Ti 1.85 )O 5 and FeTi 2 O 5 , and (iv) trans formation of ATiO 2 , which is totally from the reaction process (M 3 O 5 → ATiO 2 → RTiO 2 ) under conventional re sistance heating condition. In addition, when amorphous Fe, Mg, and Ti oxides crystallize, the Raman active vibra tion modes first was assigned to ATiO 2 lattice, then domi nated by RTiO 2 lattice. And it is important to mention that with phase transformation, there will grow tumour form on the surface of sample, which eventually develops into squamous layers.
