Abstract In the deep‐ultraviolet (DUV) region, nonlinear optical (NLO) crystals must meet stringent requirements, including a large band gap and sufficient second harmonic generation (SHG) response. Typically, these criteria are fulfilled by borates, carbonates nitrates containing π‐conjugated groups. contrast, sulfates phosphates, with polarizabilities significantly smaller than those of groups, struggle to achieve similar performance. Here, we present discovery Mg 2 PO 4 Cl, magnesium‐based phosphate, identified from over 10,000 phosphates based on polar‐axial‐symmetry screening strategy, which exhibits highest SHG response (5.2×KH (KDP)) phase‐matching ability among non‐π‐conjugated DUV transparent NLO crystals. This compound belongs Pna 1 space group, [PO ] units consistently aligned along screw axis glide planes throughout its crystal structure. Theoretical calculations attribute remarkable effect orderly arrangement heteroanionic [MgO 5 Cl] Cl polyhedra alongside isolated tetrahedra, supported Berry phase analysis. Furthermore, crystallographic structure analysis significant effects validates effectiveness our strategy. These findings offer valuable insights into origins in compounds both material design structural chemistry perspective, inspiring future efforts revitalize phosphates.

Abstract Na 3 V 2 (PO 4 ) (NVP) has garnered great attentions as a prospective cathode material for sodium-ion batteries (SIBs) by virtue of its decent theoretical capacity, superior ion conductivity and high structural stability. However, the inherently poor electronic sluggish diffusion kinetics NVP give rise to inferior rate performance unsatisfactory energy density, which strictly confine further application in SIBs. Thus, it is significance boost sodium storage material. Up now, many methods have been developed optimize electrochemical In this review, latest advances optimization strategies improving are well summarized discussed, including carbon coating or modification, foreign-ion doping substitution nanostructure morphology design. The highlighted, involving Na, V, PO 3− sites, include single-site doping, multiple-site single-ion multiple-ion so on. Furthermore, challenges prospects high-performance also put forward. It believed that review can provide useful reference designing developing toward large-scale

Abstract Organic bipolar electrodes can undergo both n‐type and p‐type reactions for energy storage due to numerous active sites, which usually deliver a high theoretical specific capacity. Herein, new polymer cathode material PQPZ is designed synthesized. The electron‐donating phenazine group undergoes two‐electron redox reaction store anions, the electron‐withdrawing phenanthraquinone sodium‐ions through reaction. Notably, as sodium‐ion batteries, exhibits reversible capacity of up 270 mAh g −1 in voltage range 1.0–4.0 V (vs. Na + /Na) achieves density 696 Wh kg half‐cell. A retention rate 90% obtained after 300 cycles at current 0.5C. More excitingly, even being cycled 10000 10C, electrode shows an average decay low 0.0036% per cycle, manifesting very stable cycling performance. In addition, also excellent performances when tested −10 °C, making it promising practical applications. Considering character PQPZ, symmetric batteries are successfully constructed, fulfilling “ready‐to‐charge” property without pre‐activation process. results reveal potential application use.
