A Comparative Investigation of Single Crystal and Polycrystalline Ni-Rich NCMs as Cathodes for Lithium-Ion Batteries

Xianming Deng et al.

Summary: Nickel-rich LiNi1-x-yCoxMnyO2 (NCM) is a promising cathode material due to its high voltage and large capacity. However, polycrystalline NCMs suffer from poor cycle stability. This study compares single crystal and polycrystalline LiNi0.84Co0.07Mn0.09O2 cathodes to understand the relationship between morphology and electrochemical performance. The results show that single crystal samples have lower capacity due to limited Li+ diffusion, but exhibit reduced cracking, side reactions, and Ni/Li mixing. These findings provide insights for developing strategies to improve rate performance and cycling stability.

Functional Electrolytes: Game Changers for Smart Electrochemical Energy Storage Devices

Faxing Wang et al.

Summary: Functional electrolytes are essential for the development of smart Electrochemical Energy Storage (EES) devices. Recent research has focused on developing stimulus-responsive electrolytes, including temperature, mechanical force, voltage, magnetism, and light-responsive electrolytes, as well as electrochromic and self-healing electrolytes. However, there are still challenges in functional electrolyte design and the development of smart EES devices.

Bulk fatigue induced by surface reconstruction in layered Ni-rich cathodes for Li-ion batteries

Chao Xu et al.

Summary: A structure-driven degradation mechanism is proposed for Ni-rich layered cathode material NMC811, in which a proportion of the material exhibits a lowered accessible state of charge and becomes fatigued after repetitive cycling. This degradation is attributed to high interfacial lattice strain between the reconstructed surface and the bulk layered structure above a distinct threshold.

Polycrystalline and Single Crystalline NCM Cathode Materials-Quantifying Particle Cracking, Active Surface Area, and Lithium Diffusion

Enrico Trevisanello et al.

Summary: The NCM family of cathode active materials with high nickel content is becoming the preferred choice for high performance lithium-ion batteries. Study shows that cracking of polycrystalline particles of NCM is not only detrimental, but also helps achieve higher reversible capacities and rate capability. Optimization of CAM size and morphology is crucial for achieving good rate capability with high-nickel NCMs.

Jinglong Liang et al.

Summary: The electrochemical reduction mechanism of Mn in LiMn2O4 in molten salt was studied, showing the reduction process from Mn (IV) to manganese as: Mn (IV)-> Mn (III)-> Mn (II)-> Mn. The reaction products include CaMn2O4, MnO, and (MnO)(x)(CaO)(1-x). The CaO in the product can be removed by washing the sample with deionized water at 0 degrees C.

Element substitution of a spinel LiMn2O4 cathode

Shu Zhang et al.

Summary: This paper comprehensively reviews the developments in restraining capacity fading and enhancing the performance of LiMn2O4 through element substitution. It thoroughly summarizes the capacity fading mechanism and categorizes the effects of element substitution into phase evolution and solid solution strengthening, which includes structure strengthening and Li+ diffusion kinetics boosting. Furthermore, a methodological approach for future element substitution research studies is proposed to guide the optimization of LiMn2O4 cathode material in the future.
