Summary: In this study, functional additives NaF and Na2CO3 were used to form a thick and stable cathode electrolyte interphase (CEI), effectively preventing capacity fading of Na0.67Fe0.5Mn0.5O2 during electrochemical cycles. The artificially induced CEI layer inhibits dissolution of transition metals and deterioration of the solid interphase, resulting in improved cyclability compared to bare Na0.67Fe0.5Mn0.5O2.

Summary: A study on glyoxylic-acetals in sodium-ion energy storage systems is presented. Compared to conventional electrolytes, these electrolytes exhibit increased thermal stabilities and higher flash points. The glyoxylic-acetal electrolyte provides competitive capacity and prolonged cycle life, and the electrode-electrolyte interphases formed in presence of glyoxylic-acetals are thicker and potentially more protective.

Summary: The safety issue of lithium-ion batteries is a critical factor limiting their large-scale application. This study investigates the structural degradation and oxygen release of LiNi0.8Co0.1Mn0.1O2 (NCM811) during the overcharge process using various in situ techniques. It is found that oxygen primarily releases from the near-surface regions, and the introduction of single-crystalline NCM811 with an integrated structure effectively inhibits morphology destruction and reduces the activation of lattice oxygen in the surface region.

Summary: This study proposes a morphology optimization strategy to address the safety hazards of NCM cathode materials under high-rate overcharging conditions. By introducing LiNi0.5Co0.25Mn0.25O2 (Ni50) with larger primary particle size and agglomeration-free morphology, the decline in electrochemical performance of Ni50 is prevented. The gas evolution and structural changes are analyzed, and it is found that the larger primary particle size lengthens Li+ extraction pathways and minimizes structural change, while decreasing the specific surface area inhibits side reactions.
