“…Therefore, after LBO modification, the stress of the LR material can be alleviated to some extent, and the loss of active lithium and structural degradation in LR material can be effectively inhibited. 42 Interestingly, the open-circle voltage (OCV) during discharge also decreases (marked by black solid line circles) after an extended cycling period. As shown in Figure S5c,f, the OCV difference value of LR@S@LBO-2% (0.1082 V) is significantly smaller than that of LR (0.3569 V).…”

“…Also, Figure b, c, e, f shows the partial diagram of XRD before and after 200 cycles, the peak deviation angles of (003) and (104) for LR materials were found to be 0.2° and 0.5°, respectively; the offset angles for LR@S@LBO-2% are 0.03° and 0.16°. Therefore, after LBO modification, the stress of the LR material can be alleviated to some extent, and the loss of active lithium and structural degradation in LR material can be effectively inhibited …”

Despite the high energy density of lithium-rich manganese-based (LR) cathode materials, the practical implementation in batteries has been impeded by the intrinsic issues regarding cycling. Herein, a coherent interface modification strategy is proposed. The LR materials are coated with a lattice-matched Li 3 BO 3 (LBO) layer at the interface. The coating applied to the electrode has two impacts. (1) It reduces interfacial side reactions between the electrode materials and electrolyte, thereby improving structural stability. (2) It mitigates stress between solid particles, which enhances the cycling stability (83% after 500 cycles at 2C) of LR. Furthermore, the LBO coating promotes the development of a spinel-like structure on the electrode materials surface, eliminating unstable oxygen, increasing oxygen vacancy (Ov), consequently enhancing the initial Coulombic efficiency (ICE, 92.18%), and alleviating particle breakage (Young's moduli of LR@S@LBO is 3.26 ± 1.6 GPa) after optimization. Theoretical calculations show that Ov and spinel can improve the diffusion of Li + and the structural stability of LR materials. This work shows great potential for the rational design of high-energy-density electrode materials.
