At the core of aluminum (Al) ion battery is liquid electrolyte, which governs underlying chemistry. Optimizing rheological properties electrolyte critical to advance state art. In present work, chloroaluminate made by reacting AlCl3 with a recently reported acetamidinium chloride (Acet-Cl) salt in an effort make more performant electrolyte. Using AlCl3:Acet-Cl as model we build on our previous ...

Sodium ion batteries (SIBs) have been considered as a promising alternative for the next generation of electric storage systems due to their similar electrochemistry to Li-ion batteries and the low cost of sodium resources. Exploring appropriate electrode materials with decent electrochemical performance is the key issue for development of sodium ion batteries. Due to the high structural stabil...

System architecture for traditional lead-acid and nickel-cadmium batteries has evolved in particular ways to meet specific application requirements. For example, valve-regulated lead-acid (VRLA) batteries for telecom outside plant (OSP) are deployed in multiple parallel strings, while vented batteries in utility substations are installed as single series strings. As users in these applications ...

Lithium-ion batteries are currently the energy storage technology of choice in portable electronic devices and electric vehicles. In recent years, sodium-ion batteries have been actively restudied as a promising alternative because of the abundance of sodium resources and the high capacity cathodes available. But as graphitic carbon can not be used as anode material, as it is in lithium batteri...

With the extensive applications of lithium ion batteries, many batteries fire and explosion accidents were reported. Base on the combustion triangle theory, the combustion triangle contributions of lithium ion battery were analysed. By using C80 micro calorimeter, the thermal behavior studies on the materials show that the flammable electrolyte, oxygen generated by charged cathode and anode dec...

Rechargeable lithium-ion batteries are essential to portable electronic devices. Owing to the rapid development of such equipment there is an increasing demand for lithium-ion batteries with high energy density and long cycle life. For high energy density, the electrode materials in the lithium-ion batteries must possess high specific storage capacity and coulombic efficiency. Graphite and LiCo...

Aqueous Al-Ion Batteries In article number 2101514, Xinhua Liu, Dennis Y. C. Leung, and co-workers propose a high-performance aqueous Al-ion battery with SWCNT cathode an aluminum foil anode. A water-in-salt electrolyte is used to provide multiple electrochemical species so that AlCl4− ions can be extracted Al3+ inserted from/into the during discharging, providing high-energy-density output. Th...

Al substitution and subsequent Na excess in 2 Mn 3 O 7 were achieved by a ceramic method, realizing the high-performance 2.4 0.4 2.6 oxygen-redox cathode for Na-ion batteries. A comparison between two cathodes revealed role of doping.
