Researchers at the U.S. Department of Energy's Argonne National Laboratory have discovered that a nanometer-thin magnesium oxide coating can significantly improve the stability of sulfide-based solid-state electrolytes. This breakthrough could be crucial for advancing next-generation solid-state batteries, which promise greater energy density and safety for electric vehicles.
The electric bicycle industry is keenly eyeing sodium-ion batteries as a potential game-changer. These next-generation power cells promise substantial cost reductions, improved safety profiles, and a decreased reliance on scarce materials such as lithium, cobalt, and nickel, addressing key pain points in current battery technology.
The electric vehicle industry is increasingly exploring sodium-ion battery technology as a compelling alternative to traditional lithium-ion cells. These batteries, which avoid critical materials like lithium, nickel, and cobalt, offer a promising pathway to reduce costs and dependence on scarce resources, accelerating the adoption of more affordable EVs globally.
Integrals Power, a UK-based company, has announced successful external validation of its lithium iron phosphate (LFP) cathode active material. Cell tests at the University of St Andrews confirmed a specific capacity exceeding 153 mAh/g, positioning their UK-produced LFP favorably against existing Chinese market leaders. This advancement could bolster the Western supply chain for crucial EV battery components.
The chairman of CATL, the world's leading EV battery manufacturer, has tempered expectations for solid-state batteries, stating the technology is currently only at "level four" on a nine-step readiness scale. He predicts that widespread adoption and commercial viability for solid-state batteries are not expected until at least 2030, suggesting the technology is still far from ready for mass production.
GM Energy is enhancing its offerings with new vehicle-to-grid (V2G) support, allowing compatible GM EVs to send power back to the home or grid. Alongside this, the company announced advancements in energy storage battery chemistry, aiming for more efficient and sustainable power solutions.
