Exploring stable and highly efficient bifunctional electrocatalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is critical for the novel energy conversion and storage devices including fuel cells and metal-air batteries. Herein, the core-shell structured Co3Fe7@Fe2N nanoparticles supported on reduced graphene oxide (rGO) nanosheets (Co3Fe7@Fe2N/rGO) is designed though the simple annealing of MOFs. The as-fabricated samples present an excellent electrocatalytic performance for ORR and OER due to the synergistic effect of electrode materials. The Co3Fe7@Fe2N/rGO exhibits an onset potential of 0.98 V (vs. Reversible hydrogen electrode), peak current intensity of 1.531 A g(-1) and long-term stability for ORR, which is close to that of the benchmark Pt/C (20%) in 0.1 M KOH. It also shows good oxygen evolution reaction (OER) performance with an overpotential of 371 mV (at 10 mA cm(-2)). When used as a bifunctional air electrode in Zn-air batteries, the core-shell materials enabled an excellent mass power density of 60 W cm(-2) g(-1) at 0.57 V and stable cycling performance for over 100 cycles.

Monolithic Phosphate Interphase for Highly Reversible and Stable Zn Metal Anode

Sailin Liu, Jitraporn (Pimm) Vongsvivut, Yanyan Wang, Ruizhi Zhang, Fuhua Yang, Shilin Zhang, Kenneth Davey, Jianfeng Mao, Zaiping Guo

Summary: To stabilize the zinc anode in zinc metal batteries, researchers have developed a controlled electrolytic method using a high dipole moment solvent dimethyl methylphosphonate (DMMP) to create a monolithic solid electrolyte interphase (SEI). This DMMP-based electrolyte generates a homogeneous and robust phosphate SEI (Zn-3(PO4)(2) and ZnP2O6). With the protection provided by this in situ monolithic SEI, the zinc electrode exhibits long-term cycling performance and high Coulombic efficiency in both zinc|zinc and zinc|copper cells. The use of a DMMP-H2O hybrid electrolyte in a full V2O5|zinc battery also results in high capacity retention following a large number of cycles.

A Dual-Functional Organic Electrolyte Additive with Regulating Suitable Overpotential for Building Highly Reversible Aqueous Zinc Ion Batteries

Zixiang Liu, Rui Wang, Quanwei Ma, Jiandong Wan, Shilin Zhang, Longhai Zhang, Hongbao Li, Qiquan Luo, Jiang Wu, Tengfei Zhou, Jianfeng Mao, Lin Zhang, Chaofeng Zhang, Zaiping Guo

Summary: Tripropylene glycol (TG) is used as an organic electrolyte additive to significantly improve the reversibility of aqueous zinc ion batteries (AZIBs). TG participates in the solvation sheath of Zn2+, regulating overpotential and inhibiting side reactions, while also inhibiting the deterioration of dendrites and modifying the direction of zinc deposition. This method can result in dendrite-free, high-performance, and low-cost energy storage systems.

Organic pH Buffer for Dendrite-Free and Shuttle-Free Zn-I2 Batteries

Yanqiu Lyu, Jodie A. Yuwono, Pengtang Wang, Yanyan Wang, Fuhua Yang, Sailin Liu, Shilin Zhang, Baofeng Wang, Kenneth Davey, Jianfeng Mao, Zaiping Guo

Summary: A class of N-containing heterocyclic compounds acts as organic pH buffers in aqueous Zn-Iodine (I-2) batteries to mitigate issues such as Zn dendrites, hydrogen evolution reaction (HER), corrosion, and polyiodines shuttle. These compounds regulate electrolyte pH, inhibit HER and anode corrosion, and preferentially absorb on Zn metal, achieving non-dendritic Zn plating/stripping. The batteries with these buffers exhibit high Coulombic efficiency, long-term cycling stability, and improved conversion kinetics.

Reduced graphene oxide-wrapped copper cobalt selenide composites as anode materials for high-performance lithium-ion batteries

Xin Hui, Jiachang Zhao, Jianfeng Mao, Hongbin Zhao

Summary: CuCo2Se4/reduced graphene oxide (rGO) composites were prepared for the first time by a solvothermal method, and applied as anode material for lithium-ion batteries (LIBs) with excellent performance. CuCo2Se4/rGO showed a reversible capacity of 845.49 mAh g-1 (0.1 A g-1) after 200 cycles, significantly better than CuCo2Se4 (36.90 mAh g-1). The rate performance of CuCo2Se4/rGO (318.4 mAh g-1 at 2 A g-1) was much better than the pure CuCo2Se4 (15.1 mAh g-1 at 2 A g-1). The results indicate a promising future for CuCo2Se4/rGO in LIBs.

Design of electrolyte for boosted aqueous battery performance: A critical review and perspective

Sailin Liu, Ruizhi Zhang, Jianfeng Mao, Jodie Yuwono, Cheng Wang, Kenneth Davey, Zaiping Guo

Summary: Aqueous alkali and multivalent metal-ion batteries have advantages in large-scale energy storage due to safety and environmental friendliness. However, they suffer from low energy density and short life due to limited electrochemical stability windows and rapid degradation of electrode materials. This review provides a systematic analysis of electrolyte design strategies, interfacial stability, and electrode/electrolyte interphases for boosted aqueous rechargeable batteries. The findings suggest that high-concentration electrolytes and hybrid solvent design show promise for high energy density ARBs, but there is a need for longer cycling life improvement and boosting electrolyte stability.

Engineering an electrostatic field layer for high-rate and dendrite-free Zn metal anodes

Kaiping Zhu, Can Guo, Wenbin Gong, Qinghua Xiao, Yagang Yao, Kenneth Davey, Qinghong Wang, Jianfeng Mao, Pan Xue, Zaiping Guo

Summary: In this study, an electrostatic field layer (EFL) was established using an electrolyte additive of cobalt tetraaminophthalocyanine (Co(TAPC)) to address the instability issue of the Zn metal/electrolyte interface, parasitic reactions, and dendritic growth, resulting in low Coulombic efficiency (CE) and poor cycle life. The Co(TAPC) with a planar and large conjugated ring structure could preferentially absorb on the Zn metal anode to form a zincophilic EFL, which prevents direct contact of Zn and water, suppresses side reactions, promotes desolvation and Zn2+ diffusion kinetics, and balances the space electric field, thereby enabling high-rate and dendrite-free Zn deposition.
