UCR team finds adding even small amounts of tin to Si-based anode greatly improves charge capacity and cycling stability

Green Car Congress

Researchers at the University of California, Riverside have found that adding tin nanoparticles—even in small amounts—to a silicon-based anode provides significant improvements in performance in terms of both charge capacity and cycling stability. In this latest work, the UCR team is tackling the conductivity issue.

Yissum offering novel high-performance anode for sodium-ion batteries; antimony sulphide nanoparticle-coated graphene

Green Car Congress

The material provides more than two times the capacity of hard carbon, retains its charge capacity even at high current rates, and exhibits a charge and discharge time of 10 minutes. This would allow fast charging of NIBs in the future, which could enable utilization in applications such as electric vehicles. Yu, Petr V.

Sandia researchers developing new family of metal-based ionic liquids for low-cost, efficient flow batteries

Green Car Congress

The US and the world need significant breakthroughs in battery technology for renewable energy sources to replace today’s carbon-based energy systems. Liquid electrolytes are pumped from storage tanks to flow-through electrodes where chemical energy is converted to electrical energy (discharge) or vice versa (charge).

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Typical ultracapacitors are characterized by high power density compared to batteries (but poor energy density), as well as quick charge and discharge. Ioxus says that the power density of its 100F carbon-carbon ultracapacitor solutions is 2x over that of competitive comparable 100F cells. Earlier post.).
