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.

Researchers exploring Li-Tellurium for high energy density batteries

Green Car Congress

The researchers suggested that their Te/C nanocomposite electrodes were suitable for use as either the cathode in Li-Te secondary batteries or as a high-potential anode in rechargeable Li-ion batteries. —Seo et al. Used as a cathode material, Se (Selenium) has shown a high capacity close to its theoretical capacity (Li 2 Se: 679?mAh

Researchers find synergy between lithium polysulfide and lithium nitrate as electrolyte additives prevent dendrite growth on Li metal anodes

Green Car Congress

However, practical applications of rechargeable lithium metal-based batteries have been hindered by the formation of dendritic and mossy lithium and associated electrolyte decomposition, resulting in safety concerns and low Coulombic efficiency.

NYC Goes EV

Revenge of the Electric Car

From the article: ‘The New York study anticipates that by 2015, electric vehicle prices should decline because of reduced battery costs, that there will be a sufficient supply of electric vehicles to purchase, and that consumers will take advantage of the existing federal tax credit of $7,500 for new electric cars. If by 2015, 2.5

MIT/Tsinghua high-rate aluminum yolk-shell nanoparticle anode for Li-ion battery with long cycle life and high capacity

Green Car Congress

Aluminium should be an attractive anode material for rechargeable Li-ion batteries for many reasons, such as low cost (~$2,000 ton −1 ), high theoretical capacity (2,235 mAh g −1 if Li 9 Al 4 , low potential plateau (~0.19–0.45 V V against Li + /Li 3 ), high electrical conductivity and so on.
