Epitaxial Electrodeposition

The propensity of metals to form irregular and nonplanar electrodeposits at liquid-solid interfaces has emerged as a fundamental barrier to high-energy, rechargeable batteries that use metal anodes. We report an epitaxial mechanism to regulate nucleation, growth, and reversibility of metal anodes. The crystallographic, surface texturing, and electrochemical criteria for reversible epitaxial electrodeposition of metals are defined and their effectiveness demonstrated by using zinc (Zn), a safe, low-cost, and energy-dense battery anode material. Graphene, with a low lattice mismatch for Zn, is shown to be effective in driving deposition of Zn with a locked crystallographic orientation relation. The resultant epitaxial Zn anodes achieve exceptional reversibility over thousands of cycles at moderate and high rates. Reversible electrochemical epitaxy of metals provides a general pathway toward energy-dense batteries with high reversibility.

Alkaline zinc-based rechargeable batteries (AZRBs) are competitive candidates for future electrical energy storage because of their low-cost, eco-friendliness and high energy density. However, plagued by dendrites, the AZRBs suffer from drastic decay in electrochemical properties and safety. This review elucidates fundamentals of zinc dendritic formation and summarizes the strategies, including electrode design and modification, electrolyte optimization and separator improvement, for suppressing zinc dendritic growth.

Abstract Rechargeable batteries paired with sodium (Na)-metal anodes are considered as one of the most promising high energy and low-cost energy storage systems. However, the use of highly reactive Na metal and the formation of Na dendrites during battery operation have caused significant safety concerns, especially when highly flammable liquid electrolytes are used. Herein, we design and develop a solvent-free solid polymer electrolytes (SPEs) based on a perfluoropolyether (PFPE) terminated polyethylene glycol (PEG)-based block copolymer for safe and stable all-solid-state Na-metal batteries. Compared with traditional poly(ethylene oxide) (PEO) or PEG SPEs, our results suggest that block copolymer design allows for the formation of self-assembled microstructures leading to high storage modulus at elevated temperatures with the PEG domains providing transport channels even at high salt concentration (EO/Na+ = 8:2). Moreover, it is demonstrated that the incorporation of PFPE segments enhances the Na+ transference number of the electrolyte to 0.46 at 80 oC. Finally, the proposed SPE exhibits highly stable symmetric cell cycling performance with high current density (0.5 mA cm-2 and 1.0 mAh cm-2, up to 1300 hours). The assembled all-solid-state Na-metal batteries with Na3V2(PO4)3 cathode demonstrate outstanding rate performance, high capacity retention and long-term charge/discharge stability (CE = 99.91%) after more than 900 cycles.

A review with 132 references. Societal and regulatory pressures are pushing industry towards more sustainable energy sources, such as solar and wind power, while the growing popularity of portable cordless electronic devices continues. These trends necessitate the ability to store large amounts of power efficiently in rechargeable batteries that should also be affordable and long-lasting. Lithium-sulfur (Li-S) batteries have recently gained renewed interest for their potential low cost and high energy density, potentially over 2600 Wh kg−1. The current review will detail the most recent advances in early 2020. The focus will be on reports published since the last review on Li-S batteries. This review is meant to be helpful for beginners as well as useful for those doing research in the field, and will delineate some of the cutting-edge adaptations of many avenues that are being pursued to improve the performance and safety of Li-S batteries.

Abstract Sodium metal batteries are widely acknowledged as one of the most promising low-cost high-energy-density batteries, but limited by uncontrollable dendritic growth and short cyclability. Herein, two-dimensional (2D) mesoporous polydopamine-graphene (mPG) heterostructures with definable pore size and sheet thickness are demonstrated as multi-functional ion redistributors to realize ultrastable, dendrite-free Na metal anodes. Benefitting from abundant sodiophilic groups (-OH, C=O and -NH-), 2D nanoporous graphene, and ordered mesoporous ion channels in mPG, the Na metal anodes show high Coulombic efficiency of >99.5%, outstanding cyclability of ~2000 h, and unprecedented rate performance of 25 mA cm-2 with 25 mAh cm-2, outperforming all the reported Na anodes stabilized by diversified strategies. What’s more, the mPG based Na/Na3V2(PO4)3 full batteries deliver exceptionally enhanced cyclability (90% retention rate after 500 cycles) and rate capacity (75 mAh g-1 at 30 C), demonstrative of impressive potential of well-designed 2D mesoporous polymers for precisely regulating Na deposition.
