Summary: Al-graphite dual-ion batteries are a promising concept for large-scale stationary electricity storage due to their safety, low cost, long cycling life, and high energy efficiency. However, the deployment of these batteries is currently limited by their low cell-level energy density. By utilizing an AlCl3-saturated IL anolyte, researchers were able to improve the energy density of the battery significantly.

Summary: This study investigates the performance of VP2 as a negative electrode alongside ionic liquids in sodium-ion batteries, revealing improved performance at intermediate temperatures and enhanced rate and cycle performance at 90 degrees C. Electrochemical tests show reduced charge transfer resistance and the formation of a uniform and stable solid electrolyte interface (SEI) layer at 90 degrees C. The conversion-based mechanism forming Na3P after charging is confirmed through X-ray diffraction and nuclear magnetic resonance spectroscopy.

Summary: The design of binder materials plays a crucial role in improving charge or mass transport in battery electrodes. However, there is a lack of design rules for aluminum-ion batteries. In this study, we applied chloric polycation binders to high-loading graphite cathodes, which enhanced ionic transport through in situ polycation-AlCl4- networks. We found that conjugated unit doping effectively improved adhesive properties and resulted in improved electrochemical performance in terms of area-specific capacity, energy efficiency, rate capability, and long-term cycling stability.

Summary: In this study, we designed a new type of Zn-ion battery by combining molecularly-precise nanographene cathodes with metallic Zn anodes. The results showed that twisted peropyrene electrodes enabled reversible Zn-ion intercalation in a nonaqueous electrolyte, which expands the design space of nonaqueous multivalent batteries. This finding is important for the development of high-voltage nonaqueous battery systems.

Summary: This study investigates the physical properties and electrochemical behavior of an inorganic ionic liquid electrolyte with high K+ concentration at an intermediate temperature, aiming to overcome the challenges faced by potassium-ion batteries (PIBs). The research successfully achieves high rate capabilities and long cycle life of graphite negative electrodes by forming a stable inorganic solid-electrolyte interphase (SEI) through the use of the electrolyte. The findings provide valuable insights into the synergistic effects between the concentrated K+ electrolyte and the all-inorganic SEI during the electrochemical operations of PIBs.

Summary: Aluminum-ion batteries operate at a lower voltage than lithium batteries. To compete, these batteries need to use inexpensive, high capacity materials. This study demonstrates the possibility of using nonmetal inorganic chloride cathodes, particularly boron with its high theoretical capacity. An experimental capacity was achieved and capacity retention was improved by adsorbing charged species with other materials, although there is still room for improvement.
