Summary: Electrically conductive polymers with hierarchically ordered structures (HOS) show significant enhancement in charge transport properties and mechanical robustness, making them critical for practical lithium-ion batteries. The conventional design of conductive polymers using bottom-up synthetic approaches and functional group modification has limitations that restrict their scaled synthesis and broad applications. By using simple primary building blocks and thermal processing, we developed conductive polymers with HOS, enabling exceptional cycling performance in lithium-ion batteries.

Summary: Due to the advantages of dual-ion batteries and abundant resources, potassium-based dual-carbon batteries have wide application prospects. However, the conventional carbonate ester-based electrolyte systems have obvious drawbacks, which seriously affect the capacity and cycle performance of K-DCBs. Therefore, a rational design of more efficient novel electrolyte systems is urgently required to realize high-performance K-DCBs.

Summary: Researchers have designed a self-supporting electrode composed of bismuth and nitrogen-doped reduced graphene oxide (Bi-80/NrGO) as an anode host for potassium-metal batteries, which addresses the issues of instability at the solid electrolyte interface (SEI) and uncontrollable growth of potassium dendrites. The K@Bi-80/NrGO electrode exhibits unique hollow pores that provide K+-diffusion channels and deposition space, maintaining electrode structure and SEI stability. This work demonstrates the potential for developing stable potassium-metal anodes with precise nucleation, smooth diffusion, and dendrite inhibition.

Summary: Aqueous electrolytes are essential for batteries due to their sustainability, greenness, and low cost. However, the reactivity of water molecules with alkali metals limits the use of high-capacity alkali-metal anodes. In this study, water molecules are confined in a carcerand-like network to create quasi-solid aqueous electrolytes (QAEs) that effectively overcome the limitations of free water molecules. The QAEs allow stable operation with alkali-metal anodes, suppressing issues such as dendrite growth, electrode dissolution, and polysulfide shuttle. The research demonstrates long-term cycling and high Coulombic efficiency of alkali-metal cells in a water-based environment, as well as the potential of full metal batteries with remarkable energy density.

Summary: Due to the large size and heavy mass of K-ion, it is challenging to find reliable anodes for K-ion batteries with outstanding comprehensive performance. This study shows that a single-atomic sulfur composite can act as a high-performance KIB anode with a great combination of capacity, cyclability, and rate. By bonding a high content of single-atomic sulfur into the carbon lattice of multi-shelled hollow nanospheres, the resulting S/C composite exhibits fast surface-dominated potassium storage and structural resilience, achieving high specific capacity and impressive cyclability.

Summary: Developing low cost, high-voltage electrolytes is important for improving the energy density and usability of lithium metal batteries (LMBs). Low concentration electrolytes have advantages in terms of cost and viscosity, but their compatibility with high-voltage LMBs is limited. In this study, a diluted low concentration electrolyte was developed by replacing a solvating cosolvent with a non-solvating cosolvent, which improved the interaction between BF4- and Li+ ions and optimized the interfacial chemistry. This electrolyte showed outstanding cycling stability and rate performance in high-loading Li-LiCoO2 full cells.

Summary: The development of high capacity potassium anodes is crucial for optimizing potassium ion batteries' performance. In this study, SbVO4@RGO anode synthesized by a one-step solvothermal method demonstrates high capacity and cycling stability, with alloying and conversion reactions occurring simultaneously. The anode shows a high capacity of 447.9 mAh g(-1) at 100 mA g(-1) and a cycling life of 500 cycles with a small average capacity decay rate of 0.106% per cycle. The transformation of SbVO4 into Sb and K3VO4 during the initial discharge process, followed by simultaneous reactions with K(+)via alloying/de-alloying and conversion reactions in the subsequent cycles, highlights the potential of SbVO4@RGO for high performance potassium anodes.

Summary: Potassium ion batteries (PIBs) are promising candidates for large-grid electrochemical energy storage systems due to their sufficient reserves and economical cost. Rational structural design based on appropriate materials, particularly nanostructural design, is essential for practical PIBs with fast ion diffusion. Different dimensional structures of anode materials, including carbon materials, metal-based chalcogenides (MCs), metal-based oxides (MOs), and alloying materials, play crucial roles in reducing resistance and alleviating stress changes in PIBs. Hopeful strategies are proposed to address current disadvantages and further experiments are encouraged to enhance electrochemical performances.
