RPI researchers develop safe, long-cycling Li-metal rechargeable battery electrode; demonstrate Li-carbon battery

Green Car Congress

Capacity and coulombic efficiency versus cycle index of Li-PGN cathodes at a rate of ~1C. O 2 and Li 3 V 1.98 Researchers at Rensselaer Polytechnic Institute have developed a safe, extended cycling lithium-metal electrode for rechargeable Li-ion batteries by entrapping lithium metal within a porous graphene network (Li-PGN).

New cathode design and understanding of electrolyte delivers greater efficiency in magnesium-ion batteries

Green Car Congress

Researchers have achieved a significant boost in the storage capacity of magnesium-ion batteries through a new design for the cathode and a new understanding of the electrolyte. Magnesium ion is known to be hard to insert into a host. More than that, magnesium ions produced in that way move extremely slowly in the host.

MIT-led team devises new approach to designing solid ion conductors; implications for high-energy solid-state batteries

Green Car Congress

Researchers led by a team from MIT, with colleagues from Oak Ridge National Laboratory (ORNL), BMW Group, and Tokyo Institute of Technology have developed a fundamentally new approach to alter ion mobility and stability against oxidation of lithium ion conductors—a key component of rechargeable batteries—using lattice dynamics.

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

A team at the Ohio State University has developed a membrane that regulates bi-directional ion transport across it as a function of its redox state and that could be used as a programmable smart membrane separator in future supercapacitors and redox flow batteries. plugin EVs to Tesla’s 85 kWh battery pack). —Herya and Sundaresan.

How Long Do Electric Car Batteries Last?

Blink Charging

Part of the answer to this question lies in the efficiency of EV batteries. Learn more about these batteries in this article, where we discuss the lifespan of different batteries and how to recycle them when the time comes. There were no recharging stations, so batteries needed to be replaced much more often. Moving Forward.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

Researchers at The Ohio State University have developed a novel strategy to improve the efficiency and performance of non-aqueous lithium-oxygen (Li-air) batteries. O 2 systems require an open system to obtain oxygen from the air; Li metal must also be used as the metal electrode to provide the lithium source. Earlier post.).
