Researchers from Griffith University in Australia and Peking University in China have synthesized low-cost, hierarchically porous, and nitrogen-doped loofah sponge carbon (N-LSC) derived from the loofah sponge via a simple calcining process and applied it as a multifunctional blocking layer for Li–S, Li–Se, and Li–I 2 batteries.

The path to delivering low-cost aircraft systems starts with engineering services, then parts fabrication, and finally system integration supporting the launch of ASX’s all-electric eVTOL aircraft, the MOBi-One. The program aims to converge automotive mass production techniques with the reliability of commercial-grade aerospace.

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. The rapid and reversible reaction kinetics of both the bromine reduction reaction and the hydrogen oxidation reaction minimize activation losses, while the low cost ($1.39 Credit: Braff et al.

Sodium can serve as an alternative to lithium in rechargeable batteries as the reversible storage mechanisms for sodium ions are very similar (e.g., Hard carbon and Sn-C nanocomposite electrodes were successfully applied as anode materials, yielding highly stable cycling performance and reversible capacities exceeding 110?mAh?g

For the proof-of-concept, the cells were manufactured to be larger than necessary to avoid unnecessary costs and lengthy manufacturing processes at this early stage. The battery for the e-bike has a design energy of 418 Wh, 250 Wh of which has been used in the e-bike proof-of-concept. Click to enlarge. Earlier post.).

In addition, the SSFCs offer simplified low-cost manufacturing of large-scale storage systems compared to conventional lithium-ion batteries.most batteries have designs that have not departed substantially from Volta’s galvanic cell of 1800, and which accept an inherently poor utilization of the active materials. —Duduta et al.

The winning concepts were: A molten air battery that uses a molten salt electrolyte at elevated temperature from Professor Stuart Licht at George Washington University. A novel rechargeable zinc battery from the research group of Professors Paul Wright and James Evans from the University of California, Berkeley.
