As one typical clean-energy technologies, lithium-metal batteries, especially high-energy-density batteries which use concentrated electrolytes hold promising prospect for the development of a sustainable world. However, concentrated electrolytes with aggregative configurations were achieved at the expense of using extra dose of costly and environmental-unfriendly salts/additives, which casts a shadow over the development of a sustainable world. Herein, without using any expensive salts/additives, we employed commercially-available low-cost and environmental-friendly molecular sieves (zeolite) to sieve the solvation sheath of lithium ions of classic commercialized electrolyte (LiPF 6 -EC/DMC), and resulting in a unique zeolite sieved electrolyte which was more aggregative than conventional concentrated electrolytes. Inspiringly, the new-designed electrolyte exhibited largely enhanced anti-oxidation stability under high-voltage (4.6 volts) and elevated temperature (55 °C). NCM-811//Li cells assembled with this electrolyte delivered ultra-stable rechargeabilities (over 1000 cycles for half-cell; 300 cycles for pouch-cell). More importantly, sustainable NCM-811//Li pouch-cell with negligible capacity decay can also be obtained through using recyclable zeolite sieved electrolyte. This conceptually-new way in preparing safe and highly-efficient electrolyte by using low-price molecular sieve would accelerate the development of high-energy-density lithium-ion/lithium-metal batteries.

Biodegradable photonic microspheres with structural colors are promising substitutes to polluting microbeads and toxic dyes. Here, amphiphilic polyester- block -poly(ethylene glycol) bottlebrush block copolymers (BBCPs) with polylactic acid or poly(ϵ-caprolactone) as the hydrophobic block are synthesized and used to fabricate eco-friendly photonic pigments. Molecular parameters of BBCPs, including rigidity and symmetry, are precisely tailored by variation of side chain lengths, which enables effective manipulation of interfacial tension ( γ ). Organized spontaneous emulsion mechanism is enabled only when γ falls in a suitable range (10.6–14.3 mN m −1 ), producing ordered water-in-oil-in-water multiple emulsions and ordered porous structures. Consequently, highly saturated and tunable structural colors are observed due to coherent light scattering from the porous structures. Such photonic materials are nontoxic as confirmed by careful safety tests using aquatic model organisms.

The occurrence and transmission of chirality is a fascinating characteristic of nature. However, the intermolecular transmission efficiency of circularly polarized luminescence (CPL) remains challenging due to poor through-space energy transfer. We report a unique CPL transmission from inducing the achiral acceptor to emit CPL within a specific liquid crystal (LC)-based intermolecular system through a circularly polarized fluorescence resonance energy transfer ( C -FRET), wherein the luminescent cholesteric LC is employed as the chirality donor, and rationally designed achiral long-wavelength aggregation-induced emission (AIE) fluorophore acts as the well-assembled acceptor. In contrast to photon-release-and-absorption, the chirality transmission channel of C -FRET is highly dependent upon the energy resonance in the highly intrinsic chiral assembly of cholesteric LC, as verified by deliberately separating the achiral acceptor from the chiral donor to keep it far beyond the resonance distance. This C -FRET mode provides a de novo strategy concept for high-level information processing for applications such as high-density data storage, combinatorial logic calculation, and multilevel data encryption and decryption.

Hydronium-ion batteries have received significant attention owing to the merits of extraordinary sustainability and excellent rate abilities. However, achieving high-performance hydronium-ion batteries remains a challenge due to the inferior properties of anode materials in strong acid electrolyte. Herein, a hydronium-ion battery is constructed which is based on a diquinoxalino [2,3-a:2’,3’-c] phenazine (HATN) anode and a MnO 2 @graphite felt cathode in a hybrid acidic electrolyte. The fast kinetics of hydronium-ion insertion/extraction into HATN electrode endows the HATN//MnO 2 @GF battery with enhanced electrochemical performance. This battery exhibits an excellent rate performance (266 mAh g −1 at 0.5 A g −1 , 97 mAh g −1 at 50 A g −1 ), attractive energy density (182.1 Wh kg −1 ) and power density (31.2 kW kg −1 ), along with long-term cycle stability. These results shed light on the development of advanced hydronium-ion batteries.

Developing A “Polysulfide‐Phobic” Strategy to Restrain Shuttle Effect in Lithium–Sulfur Batteries

引用

Angewandte Chemie 2019年第34期131卷

作者： Yibo He Yu Qiao Zhi Chang Xin Cao Min Jia Ping He Haoshen Zhou Energy Technology Research Institute National Institute of Advanced Industrial Science and Technology (AIST) 1-1-1 Umezono Tsukuba 305-8568 Japan Graduate School of System and Information Engineering University of Tsukuba 1-1-1 Tennoudai Tsukuba 305-8573 Japan Center of Energy Storage Materials&Technology College of Engineering and Applied Sciences Jiangsu Key Laboratory of Artificial Functional Materials National Laboratory of Solid State Microstructures Collaborative Innovation Center of Advanced Microstructures Nanjing University Nanjing 210093 P. R. China

Inspired by hydrophobic interface, a novel design of “polysulfide‐phobic” interface was proposed and developed to restrain shuttle effect in lithium–sulfur batteries. Two‐dimensional VOPO 4 sheets with adequate active sites were employed to immobilize the polysulfides through the formation of a V−S bond. Moreover, owing to the intrinsic Coulomb repulsion between polysulfide anions, the surface anchored with polysulfides can be further evolved into a “polysulfide‐phobic” interface, which was demonstrated by the advanced time/space‐resolved operando Raman evidences. In particular, by introducing the “polysulfide‐phobic” surface design into separator fabrication, the lithium–sulfur battery performed a superior long‐term cycling stability. This work expands a novel strategy to build a “polysulfide‐phobic” surface by “self‐defense” mechanism for suppressing polysulfides shuttle, which provides new insights and opportunities to develop advanced lithium–sulfur batteries.
