As the preferred anode material for sodium-ion batteries, hard carbon (HC) confronts significant obstacles in providing a long and dominant low-voltage plateau to boost output energy density of full batteries. The critical challenge lies precisely enhancing local graphitization degree minimize Na
A commonly used strategy to tackle the unstable interfacial problem between Li1.3Al0.3Ti1.7(PO4)3 (LATP) and lithium (Li) is introduce an interlayer. However, this has a limited effect on stabilizing LATP during long-term cycling or under high current density, which due in part negative impact of its internal defects (e.g., gaps grains (GBs)) that are usually neglected. Here, control experiments theoretical calculations show clearly GBs have higher electronic conductivity, significantly...

Abstract Ternary lithium-ion cathode materials, notably Nickel-Cobalt-Manganese (NCM), hold immense promise as key components for high-capacity and high-energy-density batteries. However, their long‐term cyclability is hindered by several challenges, primarily attributed to interlayer migration of transition metals (TM), alterations in lattice oxygen bonding, structural instability during extensive charge-discharge cycles. To address these limitations gain a deeper understanding the...
