Improvements to a class of battery electrolyte first introduced in 2017 — liquefied gas electrolytes – could pave the way to a high-impact and long-sought advance for rechargeable batteries: replacing the graphite anode with a lithium-metal anode.

By: Sam Buteau, and J. R. Dahn Abstract Electrochemical impedance spectra of lithium-ion cells can be collected periodically at various cycle numbers and various state of charges, producing vast amounts of data. Fitting each spectrum to an equivalent circuit can lead to physical insights about the evolution of the lithium-ion cell, yet the fitting problem requires good human initial guesses for the

During the last century, cars fuelled by petrol or diesel became the dominant mode of transport throughout the world. As tightening environmental regulations force automakers to reduce tailpipe emissions, motor vehicles will be increasingly powered by electricity. But the road will not be a straight one. Advances in the capabilities of electric batteries are needed to improve on performance, convenience

Highview Power reported that it developed a modular cryogenic energy storage system, the CRYOBattery™, that is scalable up to multiple gigawatts of energy storage. According to the company, the technology, which can be placed almost anywhere, reaches a new benchmark for a levelized cost of storage (LCOS) of $140/MWh for a 10-hour, 200MW/2GWh system. Highview Power contends that its cryogenic energy

Coating provides extra layer of protection for battery cathodes. Building a better lithium-ion battery involves addressing a myriad of factors simultaneously, from keeping the battery’s cathode electrically and ionically conductive to making sure that the battery stays safe after many cycles. In a new discovery, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed a new

Multi-junction solar cells are both the most efficient type of solar cell on the market today and the most expensive type of solar cell to produce. In a proof-of-concept paper, researchers from North Carolina State University detail a new approach for creating multi-junction solar cells using off-the-shelf components, resulting in lower cost, high-efficiency solar cells for use in multiple applications. Multi-junction, or

The BMW Group is accelerating its electromobility expansion program, with the 25 electrified models to be introduced by 2023, two years earlier than the initial 2025 target. With flexible vehicle architectures for fully-electric, plug-in hybrid and combustion engine drive trains, the company is able to respond quickly to changing conditions. More than half of the 25 models will be fully electric. We

Industry and commodities experts fear that the growth in electric vehicles (EVs) could be much slower than predicted due to bottlenecks in global battery market supply chains. “People seem to think that the switch from the internal combustion engine to electric vehicles just means you plug your car in rather than fill it with petrol,” a battery industry source explains.
