“…Using KCl as a molten salt, the SC‐NCA could be successfully prepared using a reduced sintering temperature of 800 °C. [ 59 ] The addition of KCl promotes ionic diffusion and so the reaction rate, and also maintain a well separation of primary particles. Single crystalline structure endows NCA improved structural stability and suppressed electrolyte decomposition during long‐term cycling, with a capacity retention of 74.5% after 200 cycles at 55 °C, significantly better than that of PC‐NCA(53.3%).…”

Li(NixCoyMnz)O2 (x + y + z = 1, NCM), as one of the most dominant cathode materials in electric vehicle (EV) batteries, faces the challenges of poor cycling stability and safety concerns with the increase of Ni content and charge/discharge capacity. Single crystalline NCM (SC‐NCM) materials have been developed to mitigate these challenges, owing to their lower surface areas, fewer grain boundaries, and better morphological stability. Here, the preparation strategies of SC‐NCM are summarized, including continuous high‐temperature sintering (CHTS), molten salt method, pulse high‐temperature sintering (PHTS), and controllable growth with special orientations or sizes. CHTS produces irregular SC‐NCM particles, but is accompanied by Li‐volatilization and agglomeration during long‐term sintering. The molten salt helps to lower calcination temperature and generate well‐defined crystalline material, but generally causes large capacity loss due to the Li/H exchange in the following water rinsing procedure. To address the above challenges, the PHTS strategy has recently been recently proposed, which mitigates Li‐loss through shortened high‐temperature stage and avoids further water rinsing steps. For improving the C‐rate performance, controllable crystal growth with specific sizes and crystal orientations is highly desired, which calls for further investigation and upgrading of current large‐scale preparation technology.

“…This regular bulk structure of CuCA is anticipated to facilitate Li + diffusion due to the absence of internal grain boundary hindrance. [47][48][49] The synthesis process of CuCA was monitored by Fourier transform infrared (FT-IR) spectra. In Figure 3a, the vibration of OÀ H at 3235 cm À 1 in CA spectrum disappears in the spectra of K 2 CA and CuCA, which indicates CA 2À ligand formation after two H + ions thoroughly divorced from CA molecule.…”

Coordination polymers can take advantage of both transition metal redox and organic ligand redox, thus serving as promising cathodes with multiple redox centers toward higher-performance lithium-ion batteries (LIBs). Here, we selected the high-capacity carbonyl compound of chloranilic acid (CA) as organic ligand to coordinate with the high-voltage Cu 2 + as transition metal node and successfully synthesized copper(II) chloranilate (CuCA) with π-d conjugation, layered structure and monocrystalline nature. The resulting CuCA presents inorganic and organic redox centers, high electronic conductivity and fast Li + diffusion kinetics, leading to high discharge capacity (297.0 mAh g À 1 at 50 mA g À 1 ), excellent rate capability (160.6 mAh g À 1 at 1000 mA g À 1 ) and good cycling stability (165.5 mAh g À 1 at 500 mA g À 1 after 50 cycles) with quasi-solid-state electrolyte. This work will provide insightful understanding of the materials design strategies to develop more efficient coordination polymer cathodes for LIBs.
