Vanderbilt researchers find iron pyrite quantum dots boost performance of sodium-ion and Li-ion batteries

Green Car Congress

nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In the paper, they reported reversible capacities of more than 500 and 600 mAh/g for sodium and lithium storage for ultrafine nanoparticles, along with improved cycling and rate capability.

PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. Nickel offers relatively low cost, wide availability and low toxicity compared to other key battery materials, such as cobalt. Nickel-rich cathode materials have real potential to store more energy.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Molten-salt batteries , as the name implies, use a liquid, molten-salt electrolyte, which freezes at room temperature, allowing the batteries to be stored in an inactive state. For future research, we are geared towards low-cost materials as well as relatively low operating temperature but still above the ambient temperature,” Li says. “We

Total Signs Research Agreement with MIT to Develop New Stationary Batteries for Solar Power; Smaller-Scale Version of All-Liquid Metal Battery Work Supported by ARPA-E

Green Car Congress

This agreement valued at $4 million over five years is part of the MIT Energy Initiative (MITEI), which Total joined as a member in November 2008. The ARPA-E award is supported the development of the liquid metal grid-scale battery for low-cost, large scale storage of electrical energy. The researchers have since switched.

European automotive and automotive battery industries call for extension of the exemption of lead-based batteries from the EU ELV Directive

Green Car Congress

The comments are part of the formal submission made by the industry group to EU regulators who concluded the public consultation phase of the review of the End of Life Vehicle (ELV) Directive this week. In full-hybrid vehicles, the stored energy is also used for a certain range of electric driving.
