The strong activity of water molecules causes a series parasitic side reactions on Zn anodes in the aqueous electrolytes. Herein, we introduce silk fibroin (SF) as multifunctional electrolyte additive for zinc-ion (Zn-ion) batteries. secondary structure transformation SF from α-helices to random coils electrolytes allows them break hydrogen bond network among free and participate Zn2+ ion solvation structure. released [Zn(H2O)4(SF)]2+ sheath appear be gradually adsorbed surface situ form...
Abstract Phosphorus doped carbons are of particular interest as anode materials because their large interlayer spacing and strong adsorption Na + ions. However, it remains challenging to achieve high phosphorus doping due the limited choices sources difficulty in constructing oxygen‐free synthesis system. Herein, a new strategy is proposed prepare ultrahigh phosphorus‐doped carbon (UPC) anodes for performance sodium ion batteries (SIBs). By using two commonly available, miscible, evaporable...
Metallic zinc anodes in zinc-ion batteries suffer from problematic Zn dendrite chemistry. Previous works have shown that preferred-orientation crystal planes can help dendrite-free metal anodes. This work reports a nanothickness (≈570 nm) AgZn3 coating to regulate the growth. First, @Zn anode avoids problem, Ag@Zn anode, rate of electrochemical Ag-Zn alloying is slower than dendrites Batteries life increased 112 h (pure Zn) and 932 (Ag@Zn) 1360 (AgZn3 @Zn) at 2 mA cm-2 1 mAh . Then, plasma...
Aqueous Zn-ion batteries are plagued by a short lifespan caused localized dendrites. High-concentration electrolytes favorable for dense Zn deposition but have poor performance in with glass-fiber separators. In contrast, low-concentration can wet the separators well, ensuring migration of zinc ions, dendrites grow rapidly. this work, we propose an electrolyte gradient strategy wherein zinc-ion concentration is established from anode to separator, that separator keeps good wettability areas...
Abstract 2D carbon nanosheets are considered to be promising candidates for use as sodium ion battery (SIB) anodes due their large specific surface area and excellent electronic conductivity. However, applications hampered by inferior cycling performance, insufficient storage capacity, high cost. N, B co‐doping (NBTs) synthesized using biomass‐based gelatin precursor boric acid template, demonstrate great potential high‐performance SIB in practical applications. The synergistic effect of...
S-doped carbon nanofibers derived from bacterial cellulose with interlinked networks and pores were facilely prepared in a sustainable approach. This product presents high Na-ion storage capacity excellent rate performances.
Recycling lithium from spent batteries is challenging because of problems with poor purity and contamination. Here, we propose a green sustainable recovery strategy for containing LiFePO4, LiCoO2, LiNi0.5Co0.2Mn0.3O2 electrodes. Our proposed configuration "lithium-rich electrode || LLZTO@LiTFSI+P3HT LiOH" system achieves double-side roll-to-roll recycling lithium-containing without destroying its integrity. The LiTFSI+P3HT-modified LLZTO membrane also solves the H+/Li+ exchange problem...
The propensity of sodium anode to form uniform electrodeposit is bound up with the nature electrode surface and regulation Na-ion flux, as well distribution electronic field, which quite crucial for high-areal-capacity metal batteries (SMBs). Herein, a novel metallic sodium/sodium-tin alloy foil (Na/NaSn) 3D interpenetrated network porous structure prepared through facile reaction. strong sodiophilic properties sodium-tin can lower nucleation energy, resulting in smaller depositing potential...

Ammonia (NH3) is one of the most frequently produced chemical products in world, and it plays an indispensable role life on Earth. However, its synthesis by Haber-Bosch (H-B) process highly energy intensive, resulting extensive carbon emissions that are unsustainable due to their ability harm environment. Herein, we propose a facile mass-producible strategy for increasing rate efficiency nitrogen fixation through use copper particle-catalyzed Li nitridation solid electrolyte as medium reduce...
The work in this paper is applied to the Zhangbei Power grid. In flexible direct current (DC) power system, fault rises extremely fast when a DC occurs. requirements for peak of breaking and energy absorption circuit breakers (DCCBs) increase linearly, which significantly increases cost equipment. Therefore, order reduce design difficulty DCCBs, proposes strategy control after Firstly, dimension added on basis traditional vector MMC, constitutes three-dimensional control. Subsequently,...
