Cathode Loading Governs the Crossover Chemistry and Organic Enrichment of the Lithium Metal Anode Interphase

Understanding interphase evolution in high-energy batteries is complicated by “crossover chemistry,” where degradation products from one electrode migrate and alter the other. While electrolyte composition and voltage are known drivers, the role of electrode mass loading remains overlooked. Here, we investigate the impact of cathode loading on crossover chemistry in a mode…

Vanadium-enhanced Na2FePO4F cathodes for high-performance sodium-ion batteries

Sodium fluorophosphate Na2FePO4F holds great promise for sodium-ion batteries due to its high theoretical capacity, excellent structural stability, abundant resources, and affordability. However, its poor electronic and ionic conductivities limit its practical applications. Therefore, ion doping and carbon coating have been employed as synergistic strategies in this study…

Influence of aluminum source and Ni/Al ratio in a batch stirred tank reactor on the structure, morphology, and electrochemical performance of Ni-rich NMA cathodes

The structural, morphological, and electrochemical performance of Ni-rich LiNi0.9Mn0.05Al0.05O2 (955NMA) and LiNi0.85Mn0.05Al0.1O2 (85,510) cathodes strongly depends on the properties of their hydroxide precursors. Ni-Mn-Al hydroxide precursors were synthesized through controlled co-precipitation in a batch stirred tank reactor, where pH, reaction time, metal-ion feed rate…

Surface modification of cathode material enhances electrochemical performance in dry-processed Li-ion battery electrodes

The transition to electric vehicles (EVs) is pivotal for achieving energy security and integrating grid stability, with lithium-ion batteries (LIBs) playing a central role in this transformation. However, the conventional wet electrode manufacturing relying on N-methyl-2-pyrrolidone (NMP) solvent is energy intensive and costly. Dry processing (DP) has emerged as a promisin…
