Flexible scintillator screens with environmental stability, high sensitivity, and low cost have emerged as candidates for X‐ray imaging applications. Here, a large‐scale and cost‐efficient solution synthesis of the vacancy‐ordered double perovskite Cs2ZrCl6, which is characterized by thermal activation delayed fluorescence (TADF) dominated by triplet emission under X‐ray irradiation, is demonstrated. The large Stokes shift and efficient luminescence collection of TADF effectively ensure the light outcoupling efficiency. Further, flexible X‐ray scintillator screens with an area of 400 cm2 are prepared using poly(dimethylsiloxane) (PDMS) as the carrier, exhibiting excellent scintillation properties with light yields as high as 49 400 photons MeV−1, spatial resolutions up to 18 lp mm−1 and detection limits as low as 65 nGy s−1. Finally, the high‐quality imaging results of non‐planar and dynamic objects by such screens are demonstrated. It is believed that the explored Cs2ZrCl6@PDMS flexible scintillator screens would offer a big step toward expanding the application range of scintillators in different environments.

“…[8] What is worse, the violent volume expansion and Li dendrite growth can not only ruin the structure of electrode but even trigger safety hazards as fire and explosion. [9,10] As the volume fluctuation, cracking/rebuilding of SEI and growth of Li dendrites during cycling of lithium metal anodes (LMAs) are highly interrelated and mutually reinforcing, the strategies that focus on different emphases have all effectively improve the cyclability of LMAs. [11][12][13][14] All in all, achieving dense and uniform Li plating morphology is crucial in decreasing the loss of active Li during cycling and raising the CE of LMAs.…”

“…A recent problem‐solving strategy involves the modification of current collectors (CCs) by constructing a porous and nano‐structured 3D framework, and has been widely studied using metal, non‐metal, and their hybrid‐based materials. [ 22–24 ] 3D architectures on CCs provide high surface area, effective Li‐ion diffusion, and large internal space, leading to the inhibition of Li dendrites and sufficient accommodation for Li storage. Using carbon‐based CCs as an alternative to metal‐based CCs can be a significantly more effective solution for Li metal batteries (LMBs) with high gravimetric energy density and their commercialization due to its unique advantages of light weight and cheap precursor.…”

Lithium is perceived as an ideal anode for next generation batteries with high‐energy density. However, the critical issue of the intractable growth of Li dendrites, which leads to a poor cycling life, still remains. Herein, a hierarchical surface is designed and constructed on carbon fiber (CF) using binders in fabricated CF paper (CFP). The lightweight CF with high mechanical properties is facilitated to establish a 3D network structure as an alternative to Cu foil. The binders are transformed into oxygen‐containing amorphous carbon and sodium carbonate (Na2CO3) using a low‐temperature carbonization process, leading to uniform Li nucleation and a stable solid electrolyte interphase layer with inorganic components. In the electrochemical test, the CFP with amorphous carbon and Na2CO3 (ANCFP) shows a low Li nucleation overpotential and smooth dendrite‐free Li plating. Furthermore, the ANCFP electrode exhibits good cycling stability in half and symmetrical cells. A full‐cell assembled using a LiFePO4 cathode with high loading (≈13 mg cm−2) achieves a high‐energy density of 428 Wh kg−1 (at 0.1 C) and an excellent capacity retention of 85% at 1 C after 300 cycles. This strategy is expected to help realize highly stable Li metal anodes for practical application by suppressing Li dendrite growth.
