Sumary of An atomic look at lithium-rich batteries:
- A team of researchers believes a paradigm shift is necessary to make a significant impact in battery technology for these industries..
- Findings published in Nature mark the first time direct observation of this anionic redox reaction has been observed in a lithium-rich battery material..
- Scientists need a clear understanding of how these oxides work at the atomic level, and how their underlying electrochemical mechanisms play a role, to address this..
- Normal Li-ion batteries work by cationic redox, when a metal ion changes its oxidation state as lithium is inserted or removed..
- This is the mechanism credited with the high capacity of the materials, nearly doubling the energy storage compared to conventional cathodes..
- Although this redox mechanism has emerged as the leading contender among battery technologies, it signifies a pivot in materials chemistry research..
- The team set out to provide conclusive evidence for the redox mechanism utilizing Compton scattering, the phenomenon by which a photon deviates from a straight trajectory after interacting with a particle (usually an electron)..
- The researchers performed sophisticated theoretical and experimental studies at SPring-8, the world’s largest third-generation synchrotron radiation facility which is operated by JASRI….
