Researchers propose new VO2 cathode material for aluminum-ion rechargeable battery

Green Car Congress

Sodium-ion and magnesium-ion batteries, as new energy storage systems in portable devices, have attracted much attention of the investigators. However, the concerns regarding the high cost and the limited lithium reserves in the earth’s crust have driven the researchers to search more sustainable alternative energy storage solutions.

New high-performance Na-ion battery with SO2-based catholyte; potential for other non-Li-metal-based battery systems

Green Car Congress

Researchers in South Korea have demonstrated new type of room-temperature and high-energy density sodium rechargeable battery using a sulfur dioxide (SO 2 )-based inorganic molten complex catholyte that serves as both a Na + -conducting medium and cathode material (i.e. catholyte). mA cm −2 ). The cutoff voltage for charge is 4.05 V.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. Sodium-ion based rechargeable batteries (SIBs, e.g., earlier post ) are of interest due to sodium’s abundance, far lower prices, and a greener synthesis while maintaining a similarity in ion-insertion chemistry.

Sulfur–TiO2 yolk-shell cathode for Li-sulfur battery shows best long-cycle performance so far

Green Car Congress

However, many challenges remain in developing a practical lithium–sulphur battery for commercialization. The sulfur cathode stored up to five times more energy per sulfur weight than today’s commercial materials. Even without optimizing the design, this cathode cycle life is already on par with commercial performance.

Sadoway and MIT team demonstrate calcium-metal-based liquid metal battery

Green Car Congress

MIT professor Donald Sadoway and his team have demonstrated a long-cycle-life calcium-metal-based liquid-metal rechargeable battery for grid-scale energy storage, overcoming the problems that have precluded the use of the element: its high melting temperature, high reactivity and unfavorably high solubility in molten salts.
