A quinone-based oligomeric lithium salt for superior Li–organic batteries

Energy & Environmental Science (2014)

Zhiping Song Yumin Qian Xizheng Liu Tao Zhang Yanbei Zhu

Organic electrode materials are promising alternatives to transition-metal based intercalation compounds for the next generation of high-performance and sustainable batteries. Herein, a novel quinone-based organic, lithium salt of poly(2,5-dihydroxy-p-benzoquinonyl sulfide) (Li2PDHBQS), was successfully synthesized through a simple one-step polycondensation reaction, and applied as a cathode for Li–organic batteries. As an oligomeric lithium salt with average polymerization degree of 7, Li2PDHBQS combines the advantages of the O⋯Li⋯O coordination bond and increased molecular weight, thus solves absolutely the dissolution problem of active material in non-aqueous electrolytes, which has seriously hindered development of organic electrode materials. Benefiting from the high theoretical capacity, intrinsic insolubility, fast reaction kinetics of the quinone group, accelerated Li-ion transport and uniform blending with conductive carbon, as well as the stable amorphous structure, Li2PDHBQS shows superior comprehensive electrochemical performance including high reversible capacity (268 mA h g−1), high cycling stability (1500 cycles, 90%), high rate capability (5000 mA g−1, 83%) and high Coulombic efficiency (99.9–100.1%). Investigation of the structure–property relationship of Li2PDHBQS and its analogues also gives new insights into developing novel quinone-based organic electrode materials, for building better Li–organic or Na–organic batteries beyond traditional Li-ion batteries.

Water induced ultrathin Mo2C nanosheets with high-density grain boundaries for enhanced hydrogen evolution

Nature Communications (2022)

Yang Yang Yumin Qian Zhaoping Luo Haijing Li Lanlan Chen

Grain boundary controlling is an effective approach for manipulating the electronic structure of electrocatalysts to improve their hydrogen evolution reaction performance. However, probing the direct effect of grain boundaries as highly active catalytic hot spots is very challenging. Herein, we demonstrate a general water-assisted carbothermal reaction strategy for the construction of ultrathin Mo2C nanosheets with high-density grain boundaries supported on N-doped graphene. The polycrystalline Mo2C nanosheets are connected with N-doped graphene through Mo-C bonds, which affords an ultra-high density of active sites, giving excellent hydrogen evolution activity and superior electrocatalytic stability. Theoretical calculations reveal that the dz2 orbital energy level of Mo atoms is controlled by the MoC3 pyramid configuration, which plays a vital role in governing the hydrogen evolution activity. The dz2 orbital energy level of metal atoms exhibits an intrinsic relationship with the catalyst activity and is regarded as a descriptor for predicting the hydrogen evolution activity.

O-coordinated W-Mo dual-atom catalyst for pH-universal electrocatalytic hydrogen evolution

Science Advances (2020)

Yang Yang Yumin Qian Haijing Li Zhenhua Zhang Yue‐Wen Mu

Single-atom catalysts (SACs) maximize the utility efficiency of metal atoms and offer great potential for hydrogen evolution reaction (HER). Bimetal atom catalysts are an appealing strategy in virtue of the synergistic interaction of neighboring metal atoms, which can further improve the intrinsic HER activity beyond SACs. However, the rational design of these systems remains conceptually challenging and requires in-depth research both experimentally and theoretically. Here, we develop a dual-atom catalyst (DAC) consisting of O-coordinated W-Mo heterodimer embedded in N-doped graphene (W1Mo1-NG), which is synthesized by controllable self-assembly and nitridation processes. In W1Mo1-NG, the O-bridged W-Mo atoms are anchored in NG vacancies through oxygen atoms with W─O─Mo─O─C configuration, resulting in stable and finely distribution. The W1Mo1-NG DAC enables Pt-like activity and ultrahigh stability for HER in pH-universal electrolyte. The electron delocalization of W─O─Mo─O─C configuration provides optimal adsorption strength of H and boosts the HER kinetics, thereby notably promoting the intrinsic activity.

Stable Li–Organic Batteries with Nafion‐Based Sandwich‐Type Separators

Advanced Energy Materials (2016)

Zhiping Song Yumin Qian Minoru Otani Haoshen Zhou

Similar to Li–S batteries, Li–organic batteries have also been plagued by the dissolution of active materials and the resulting shuttle effect for many years. An effective strategy to eliminate the shuttle effect is adopting solid electrolytes or Li–ion permselective separators to prohibit the dissolved electroactive species from migrating to the Li anode. A polypropylene/Nafion/polypropylene (PNP) sandwich‐type separator is reported with many advantages in comparison with previously reported LISICON, polymer electrolyte, and other Nafion utilization forms. The physical and chemical properties of PNP separators are studied in detail by cross‐section scanning electron microscopy (SEM), infrared spectroscopy (IR), and electrochemical impedance spectroscopy. 1,1′‐Iminodianthraquinone (IDAQ), a novel organic cathode, is taken as an example to quantitatively investigate the function of PNP separators. In the presence of PNP5 with the most appropriate Nafion loading of 0.5 mg cm –2 , IDAQ is able to achieve dramatically improved cycling stability with capacity retention of 76% after 400 cycles and Coulombic efficiency above 99.6%, which reaches the highest level for reported soluble organic electrode materials. Besides Li–organic batteries, such kind of Nafion‐based sandwich‐type separators are also promising for Li–S batteries and other new battery designs involving dissolved electroactive species.
