Transition metal oxide CoO has attracted extensive attention as a potential anode material for lithium-ion batteries (LIBs) due to its impressive theoretical specific capacity. However, pristine often suffers from structural collapse during cycling, resulting in reduced To address these challenges, we developed method situ grow octahedral nanoparticles on hierarchical multilayer MoB MBene. The matched layer gradients and heterojunction formation between MBene effectively accommodate the volume expansion of CoO. Following 200 cycles at 100 mA/g, CoO/MoB electrode achieves capacity 819.8 mAh/g, significant 2.58-fold performance improvement over Even 1000 composite retains 601.3 mAh/g after 600 cycles, while only 142.4 mAh/g. This breakthrough suggests holds great promise improving LIBs may pave way development advanced materials.

Abstract Information storage and encryption systems often suffer from degradation instability at elevated temperatures. This work introduces a robust ion‐based information system that demonstrates exceptional temperature resistance up to 350 °C, achieved through the immobilization of monoatomic cations (Li + , Na K ) in carbon nitride via light exposure. By creating electron trap states within matrix, exposure enables photo‐charging material, transforming it into capacitor capable dynamic, reversible color changes for encoding encrypting information. Notably, ionic state material serves as foundation data storage, offering an inherent security feature where trapped electrons are quenched upon air encrypted can be reactivated charging. study establishes novel paradigm high‐temperature using control ion movement with precision security.
