U Delaware team develops prototype efficient direct ammonia fuel cell for transportation

Green Car Congress

With recent and projected cost declines in wind, solar, and lithium-ion batteries, electrification using batteries has become a viable option for applications compatible with the inherent range limitations and recharging time. Source-to-Tank cost comparison of carbon-neutral transportation fuels. Zhao et al. —Zhao et al.

Researchers virtually ‘unwind’ lithium battery; strategies for improving design of cylindrical cells

Green Car Congress

The cylindrical windings of the battery are difficult to examine quantitatively, and the cell cannot be unwound without inducing further damage that would not be present in an unwound battery.

Fraunhofer ICT Working on New Redox Flow Batteries with Improved Capacity for EV Applications

Green Car Congress

The devices could theoretically be recharged at a station in a few minutes. “ The discharged electrolyte is simply pumped out and replaced with recharged fluid. The pumped-off electrolyte can be recharged at the gas station, for example, using a wind turbine or solar plant ,” says engineer Jens Noack from ICT.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

The rise of renewable solar and wind power is demanding sustainable storage technologies using components that are inexpensive, Earth-abundant and environmental friendly. The researchers focused mainly on the favorable cost-performance comparisons between their sodium-ion battery and lithium.

For comparison, conventional batteries without direct cooling of the cells achieve about half this figure. The electric power can always be called up and frequently reproduced via high recuperation performance and needs-based recharging. Strong battery recharging at low power demand for maximum electrical availability.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. The scientists found the nanofluids could be used in a system with an energy-storing potential approaching that of a lithium-ion battery and with the pumpable recharging of a flow battery.
