“…(1) Graphene film electrodes: Because of the soft and two-dimensional nature, graphene tends to stack and form compact films, thus exhibiting high volumetric capacities. − However, this highly compacted structure has few pores to act as ion-transport channels, corresponding to low utilization of the active materials . To solve this problem, creating holes in graphene is proven to be an effective method, but it destroys the 2D graphene structure and thus reduces the conductivity of the electrode. , (2) Fibrous film electrode: Interweaving of carbon fibers loaded with active materials can generate fibrous film electrodes, in which large pores between the fibers would serve as ion-transport channels. − Unfortunately, the high porosity will lower the volumetric capacity. Hence, it can be seen that it is challenging to achieve a balance between high compactness and porosity, which is imperative for the electrode to achieve high volumetric capacity.…”

A highly densified electrode material is desirable to achieve large volumetric capacity. However, pores acting as ion transport channels are critical for high utilization of active material. Achieving a balance between high volume density and pore utilization remains a challenge particularly for hollow materials. Herein, capillary force is employed to convert hollow fibers to a bamboo-weaving-like flexible electrode (BWFE), in which the shrinkage of hollow space results in high compactness of the electrode. The volume of the electrode can be decreased by 96% without sacrificing the gravimetric capacity. Importantly, the conductivity of BWFE after thermal treatment can reach up to 50,500 S/m which exceeds that for most other carbon materials. Detailed mechanical analysis reveals that, due to the strong interaction between nanoribbons, Young’s modulus of the electrode increases by 105 times. After SnO2 active materials is impregnated, the BWFE/SnO2 electrode exhibits an exceptionally ultrahigh volumetric capacity of 2000 mAh/cm3.

PbS quantum dots (QDs) are promising building blocks for solution‐processed short‐wavelength infrared (SWIR) devices. The recently developed direct synthesis of semi‐conductive PbS QD inks has substantially simplified the preparation processing and reduced the material cost, while facing the challenge to synthesize large‐size QDs with absorption covering the SWIR region. Herein, we for the first time realize a low‐cost, scalable synthesis of SWIR PbS QD inks after an extensive investigation of the reaction kinetics. Finally, based on these PbS SWIR QD inks, the solar cell demonstrates a record‐high power conversion efficiency (PCE) of 1.44 % through an 1100 nm cutoff silicon filter and the photodetector device shows a low dark current density of 2×10−6 A cm−2 at −0.8 V reverse bias with a high external quantum efficiency (EQE) of 70 % at ≈1300 nm. Our results realize the direct synthesis of low‐cost and scalable SWIR QD inks and may accelerate the industrialization of consumer SWIR technologies.
