Editors’ Choice—Quantification of the Impact of Chemo-Mechanical Degradation on the Performance and Cycling Stability of NCM-Based Cathodes in Solid-State Li-Ion Batteries
The use of solid electrolytes in lithium batteries promises to increase their power and energy density, but several challenges still need to be overcome. One critical issue is capacity-fading, commonly ascribed to various degradation reactions in the composite cathode. Chemical,…
The hidden culprit killing lithium-metal batteries from the inside
The first nanoscale images ever taken inside intact, lithium-metal coin batteries (also called button cells or watch batteries) challenge prevailing theories and could help make future high-performance batteries, such as for electric vehicles, safer, more powerful and longer lasting.
Is battery recycling environmentally friendly?
In a new study, researchers at Aalto University have investigated the environmental effects of a hydrometallurgical recycling process for electric car batteries. The carbon footprint of the raw material obtained by the recycling process studied is 38% smaller than that of the virgin raw material. The difference is even greater if copper and aluminium recovered during mechanical pre-treatment are included.
A new approach boosts lithium-ion battery efficiency and puts out fires, too
This new technology addresses two major goals of battery research: extending the driving range of electric vehicles and reducing the danger that laptops, cell phones and other devices will burst into flames.

Dr. Arumugam “Ram” Manthiram on a Pandemic Wake-up Call
In ECS series, The ECS Community Adapts and Advances, Dr. Arumugam “Ram” Manthiram shares how he is in awe of his research team’s ability to remain creative and productive amidst to COVID-19 pandemic. He also urges the science community to be proactive in confronting the pandemic and climate change challenges threatening the global community.
Fluorine recycling for lithium-ion batteries
Lithium-ion batteries contain salts rich in fluorine, which decompose in humid air to toxic, highly corrosive hydrogen fluoride. The hazardous nature of this substance makes recycling more difficult and more expensive. A research project entitled “Fluoribat” is now being launched at Empa to solve this problem. This could help to make the life cycle of a rechargeable battery less expensive and at the same time safer.
