Articles

Dr. Schmuch, Dr. Siozios, Professor Dr. Winter, and Dr. Placke review the challenges and opportunities of nickelrich layered oxide cathode materials. They discuss production processes for the layered oxide cathode materials as well as their chemistry and morphology.

Li-ion batteries are currently the focus of numerous research efforts with applications designed to reduce carbon-based emissions and improve energy storage capabilities.

Lithium-ion batteries (LIBs) have been widely adopted as the most promising portable energy source in electronic devices because of their high working voltage, high energy density, and good cyclic performance.

The critical technical challenges associated with the commercialization of electric vehicle batteries include cost, performance, abuse tolerance, and lifespan.
