Abstract Efficient and stable photocathodes with versatility are of significance in photoassisted lithium-ion batteries (PLIBs), while there is always a request on fast carrier transport electrochemical active photocathodes. Present work proposes general approach creating bulk heterojunction to boost the mobility by simply laser assisted embedding plasmonic nanocrystals. When employed PLIBs, it was found effective for synchronously enhanced photocharge separation light charging process. Additionally, experimental photon spectroscopy, finite difference time domain method simulation theoretical analyses demonstrate that improved dynamics driven plasmonic-induced hot electron injection from metal TiO 2 , as well conductivity matrix due formation oxygen vacancies after Schottky contact. Benefiting these merits, several benchmark values performance -based photocathode applied PLIBs set, including capacity 276 mAh g −1 at 0.2 A under illumination, photoconversion efficiency 1.276% 3 less Columbic loss even through 200 cycles. These results exemplify potential strategy developing highly efficient energy storage systems.

Niobium pentoxide (T-Nb2O5) is a promising anode material for dual-ion batteries due to its high lithium capacity and fast ion storage release mechanism. However, T-Nb2O5 suffers from the disadvantages of poor electrical conductivity cycling decay. Herein, nitrogen-doped three-dimensional porous carbon (RMF) was prepared loading niobium construct composite system with excellent electrochemical performance. The obtained T-Nb2O5/RMF composites have well-developed pore structure specific surface area 1568.5 m2 g-1, which could effectively increase contact between electrolyte, improving electrode reaction lithium-ion transfer diffusion. Nitrogen doping increased polarity, creating more active sites accelerating rate. introduction imparted power density stability battery. exhibited good performance when used as battery anode, stable cycle life 207.2 mA h g-1 at 1 A current after 650 cycles great rate 181.5 5A also obtained. This work provides possibility applying an high-performance

Dual-ion batteries (DIBs) were demonstrated as a promising technology for large-scale energy storage due to their low cost, recyclability, and impressively fast charge capability. Graphite commonly used cathode material in DIBs, however, suffers from poor compatibility with commercial Li-ion electrolytes graphite anodes, making it difficult directly utilize the well-established infrastructure batteries. Herein, we report small aromatic amine molecule 4,4′,4″-tris(diphenylamino)triphenylamine (N4) functioning compatible anion host EC-containing electrolyte. With an average discharge voltage of 3.6 V (vs. Li+/Li), N4 electrode delivers reversible specific capacity 108 mAh/g, which is much higher than 29 mAh/g at same condition. The high retention 91.3% was achieved after 500 cycles 1 A/g. also exhibited good rate performance. Via different characterization techniques like Fourier transform infrared spectroscopy X-ray photoelectron spectroscopy, mechanism revealed conversion between quaternary cations, accompanied by PF6− (de-)insertion. As consequences, assembled N4||graphite DIB w showed 90 within 1.5–4.1 V, cycling stability 98% 40 cycles. Decent performance well. This work provides new insights into designing affordable DIBs.

Abstract With the ever‐increasing demand for high power and energy batteries, extensive researches devote to voltage cathode materials. Graphite cathode‐based dual‐ion batteries (DIBs) possess unique advantages of working (≈4.5−5.0) power, but still suffer from low coulombic efficiency poor long‐term stability mainly resulted by serious oxidative decomposition electrolytes significant structural deterioration graphite cathode. From perspectives simultaneously reinforcing mechanical strength suppressing via a cathode/electrolyte interphase (CEI), polyacrylic acid (PAA) is adopted as surface modifier natural (NG). The significantly improved virtue bonding interaction between PAA binder, which validated through both theoretical calculation experimental observation. In addition, contributes formation LiF‐rich homogeneous CEI preferential adsorption anions, effectively mitigates cointercalation solvent. As material DIBs, NG@PAA manifests fast charge/discharge capability outstanding capacity retention 73.9% after 8000 cycles. This work provides modification strategy optimizing performance electrode materials multiple perspectives.
