Atomic Sn–enabled high-utilization, large-capacity, and long-life Na anode

Science Advances (2022)

Fei Xu Changzhen Qu Qiongqiong Lu Jiashen Meng Xiuhai Zhang

Constructing robust nucleation sites with an ultrafine size in a confined environment is essential toward simultaneously achieving superior utilization, high capacity, and long-term durability in Na metal-based energy storage, yet remains largely unexplored. Here, we report a previously unexplored design of spatially confined atomic Sn in hollow carbon spheres for homogeneous nucleation and dendrite-free growth. The designed architecture maximizes Sn utilization, prevents agglomeration, mitigates volume variation, and allows complete alloying-dealloying with high-affinity Sn as persistent nucleation sites, contrary to conventional spatially exposed large-size ones without dealloying. Thus, conformal deposition is achieved, rendering an exceptional capacity of 16 mAh cm-2 in half-cells and long cycling over 7000 hours in symmetric cells. Moreover, the well-known paradox is surmounted, delivering record-high Na utilization (e.g., 85%) and large capacity (e.g., 8 mAh cm-2) while maintaining extraordinary durability over 5000 hours, representing an important breakthrough for stabilizing Na anode.

Sodium-Ion Batteries: Novel K₃V₂(PO₄)₃/C Bundled Nanowires as Superior Sodium-Ion Battery Electrode with Ultrahigh Cycling Stability (Adv. Energy Mater. 17/2015)

Advanced Energy Materials (2015)

Xuanpeng Wang Chaojiang Niu Jiashen Meng Ping Hu Xiaoming Xu

In article number 1500716, Liang Zhou, Liqiang Mai, and co-workers report the fabrication of K3V2(PO4)3/C bundled nanowires using a facile organic-acid-assisted method. The organic acid acts as a carbon precursor and as a directing agent, promoting the formation of K3V2(PO4)3/C bundled nanowires. With a highly stable framework, nanoporous structure, and conductive carbon coating, K3V2(PO4)3/C bundled nanowires exhibit fast ion diffusion and excellent electron conduction when used as a cathode material for sodium-ion batteries.

Advances in Fine Structure Optimizations of Layered Transition‐Metal Oxide Cathodes for Potassium‐Ion Batteries

Advanced Energy Materials (2022)

Xuanpeng Wang Zhitong Xiao Kang Han Xiao Zhang Ziang Liu

Abstract Potassium‐ion batteries (PIBs) have attracted significant research interest in the context of driving the advancement of grid energy storage due to K's elemental abundance and high theoretical output voltage. The main challenge facing PIBs is to find suitable cathode materials with fast transport kinetics and stable framework structures to intercalate/de‐intercalate the large‐size K + . Among these candidates, transition‐metal layered oxides are have excellent potential and have been extensively exploited due to their stable skeleton structure, simple synthetic chemistry, and high working potential. Herein, the current research status and prospects of layered transition‐metal oxide cathodes are summarized, especially focussing on the fine structure optimization engineering and energy storage mechanism. In addition, a brief overview of the research on advanced characterization techniques for PIBs is introduced in detail. Finally, the main research directions and hot spots of new‐type transition‐metal layered oxide cathode are also predicted, in order to guide the future development of advanced PIBs.

High‐Capacity Sub‐Nano Divalent Silicon from Biosilicification

Advanced Energy Materials (2023)

Zi'ang Liu Xuanpeng Wang Jingwen Hu Jiashen Meng Chaojiang Niu

Abstract In terms of high capacity and reliable safety, low‐valent silicon‐based composites with small grain sizes are practicable anode materials for lithium‐ion batteries. However, robust tetravalent silicon precursors make the synthesis hard to be green. Using biosilicification in water hyacinth ( Eichhornia crassipes ), it is found to be a superior natural precursor of low‐valent silicon. The biogenic sub‐nano (0.5 nm) siliceous dots composite (EC‐SiOC) shows a reversible conversion mechanism between Si─O and C─O bonds, unlike previous lithium storage mechanisms associated with alloying reactions. Due to the homogeneous biogenic structure facilitating the solid‐phase reaction, the normalized energy consumption of pyrolytic EC‐SiOC is about 80% lower than the carbothermic reduction of silica, similar to molten salt electrolysis. Statistically, the sampling survey of EC‐SiOC from different regions shows a high average capacity of 749.9 mAh g −1 under a current density of 100 mA g −1 . This study reveals the great potential of biomass precursors for synthesizing Si─O─C materials.

Oxygen evolution reaction dynamics monitored by an individual nanosheet-based electronic circuit

Nature Communications (2017)

Peiyao Wang Mengyu Yan Jiashen Meng Gengping Jiang Longbing Qu

The oxygen evolution reaction involves complex interplay among electrolyte, solid catalyst, and gas-phase and liquid-phase reactants and products. Monitoring catalysis interfaces between catalyst and electrolyte can provide valuable insights into catalytic ability. But it is a challenging task due to the additive solid supports in traditional measurement. Here we design a nanodevice platform and combine on-chip electrochemical impedance spectroscopy measurement, temporary I-V measurement of an individual nanosheet, and molecular dynamic calculations to provide a direct way for nanoscale catalytic diagnosis. By removing O2 in electrolyte, a dramatic decrease in Tafel slope of over 20% and early onset potential of 1.344 V vs. reversible hydrogen electrode are achieved. Our studies reveal that O2 reduces hydroxyl ion density at catalyst interface, resulting in poor kinetics and negative catalytic performance. The obtained in-depth understanding could provide valuable clues for catalysis system design. Our method could also be useful to analyze other catalytic processes.Electrocatalysis offers important opportunities for clean fuel production, but uncovering the chemistry at the electrode surface remains a challenge. Here, the authors exploit a single-nanosheet electrode to perform in-situ measurements of water oxidation electrocatalysis and reveal a crucial interaction with oxygen.
