Summary: The development of photo-enhanced lithium-ion batteries, where exposing the electrodes to light results in higher capacities, higher rate performance or self-charging, has recently gained substantial traction. The challenge in these devices lies in the realisation of photo-electrodes with good optical and electrochemical properties. Herein, we propose copper-hexahydroxybenzene as the active photo-electrode material which both harvests light and stores energy. This material was mixed with reduced graphene oxide as a conductive additive and charge transfer medium to create photo-active electrodes. Under illumination, these electrodes show improved charge storage kinetics resulting in the photo-accelerated charging and discharging performance (i.e. specific capacities improvement from 107 mA h g(-1) to 126 mA h g(-1) at 200 mA g(-1) and 79 mA h g(-1) to 97 mA h g(-1) at 2000 mA g(-1) under 1 sun illumination as compared to dark).

Summary: This work investigates the cycling stability of silicon-based half and full cells at a wide temperature range and the associated capacity fading mechanisms. Results show that low temperature causes a decrease in capacity due to sluggish kinetics, and high temperature results in the lowest first Coulombic efficiency and the worst cycling stability with different capacity fading mechanisms. In addition, composition and stability of solid-electrolyte interphase films are strongly temperature sensitive. This work has important guiding significance for promoting the development and application of Si anodes in lithium ion batteries.

Summary: This work proposes an artificial cathode/electrolyte interphase (CEI) strategy by implanting polyphosphoric acid (PPA) nanofilms tightly on natural graphite (NG) particles, which significantly improves the performance of the graphite cathodes. The enhanced performance is mainly attributed to the PPA-based CEI, which effectively mitigates the electrolyte decomposition and protects the graphitic structure. Additionally, the hydrogen bonding interactions between PVDF binder and PPA, as well as the cross-linking effect of PPA, contribute to the improved mechanical stability and long life of the NG@PPA cathode.

Summary: This study proposes a three-dimensional binder network synthesized by weaving Ni2+ anchored soft gellan gum chains with linear rigid polyvinyl alcohol chains. The obtained binder exhibits soft-rigid synergy and self-recovery ability, enabling the Si anode to deliver over 1500 mAh g-1 after 500 cycles at 2.1 A g-1. The binder can buffer the volume changes of Si particles and retain the overall stability of the electrode. Furthermore, the optimized Si anode shows a high capacity retention of approximately 50% even at 84 A g-1 due to the provision of uniform Li+ flux and more Li+ transport channels by the binder network.

Experiments and simulations confirm the existence of pi-pi stacking interactions between the unsaturated sulfonates and graphite layers. The newly-formed cathode/electrolyte interphase layer effectively prevents electrolyte decomposition, reduces interfacial resistance, and protects the graphite cathode from structural degradation. The resulting cathode material demonstrates outstanding cycling performance in dual-ion batteries due to the strong adhesion capability of the unsaturated sulfonates on graphite.
