While the intrinsic safety and capacity merits of Li3VO4 endow it with great promise in LIBs, the moderate lifespan under a high rate hinders its practical application. Herein, we demonstrate for the first time, the boosting of an unprecedented high-rate performance of the Li3VO4-based electrode via a novel honeycomb architecture design and its electrochemical reconstruction upon cycling. Li3VO4/C honeycombs (LVO/C Hs) consisting of primary carbon-coated Li3VO4 nanoparticles have been constructed by a self-assembly strategy, through a developed electrospraying approach using polyvinyl alcohol as a morphology regulator. In the LVO/C Hs, the local LVO@C nanoparticle constituents render high activity, and the integral honeycomb-like architecture facilitates electron transfer and promotes a synergistic effect between the constituents. The lithiation-driven electrochemical reconstruction in cycling ensures the integrity of the honeycomb structure, and at the same time, the LVO nanoparticles are refined to 3–5 nm, producing abundant nanopores. The self-reconfigured structures with ultrasmall nanoparticles and large void space effectively shorten the ion diffusion pathway. The above structural characteristics trigger a continuous high capacitive charge storage, giving rise to unprecedented high-rate performance. The LVO/C Hs electrode delivered a discharge capacity recovery of 590.0 mA h g−1 at 0.5 A g−1 after 6 periodic rate performance tests from 0.5 to 10 A g−1 over 430 cycles. When cycling at a high discharge current of 6 A g−1, the LVO/C Hs electrode could maintain stable cycling over 14 000 cycles with a high discharge capacity of 324.5 mA h g−1. The lifespan of the LVO/C Hs is the longest among all the reported LVO-based electrodes, demonstrating great potential in long-life and high-rate applications such as electric vehicles and power stations.

Auditory verbal hallucinations (AVHs) are a core symptom of schizophrenia, and resistant to antipsychotic medication in a substantial proportion of patients. This study aimed to investigate the neural correlates of AVHs in schizophrenia patients and its response to a modified continuous theta-burst stimulation (cTBS) by transcranial magnetic stimulation. In a cross-sectional experiment, resting-state functional magnetic resonance images were collected from 31 AVH schizophrenia patients, 26 non-AVH schizophrenia patients, and 33 sex-/age-matched healthy controls (HCs). Functional connectivity strength (FCS) maps were compared among groups by 1-way analysis of variance (ANOVA). In a longitudinal experiment, 16 and 11 AVH patients received real and sham cTBS treatment for 15 days, respectively. Notably, this was not a randomized control trail. Changes in AVH and FCS were analyzed by 2-way ANOVA and 2-sample t -test, respectively. In the cross-sectional experiment, comparison of FCS maps identified 8 clusters among groups, but only one cluster (in left cerebellum) differed significantly in AVH patients compared to both HCs and non-AVH patients. In the longitudinal experiment, the real cTBS group showed a greater improvement in symptoms and a larger FCS decrease in left cerebellum than the sham group. Pearson's correlation analysis indicated that baseline FCS of the overlapping cerebellum cluster (between the cross-sectional and longitudinal findings) was negatively correlated with symptom improvement in the real treatment group. These findings emphasize the role of the left cerebellum in both the pathophysiology and clinical treatment of AVHs in schizophrenia patients. [ABSTRACT FROM AUTHOR]
