Batteries Determining their own State

 Was of interest to us when we were making batteries.

Commercial battery cells that can monitor their own chemical and thermal state  by Ingrid Fadelli , in TechExplore

Battery technology can sometimes be unstable and volatile, two characteristics that impair its safety and reliability. Actively monitoring the chemical and thermal state of battery cells over time could help to detect changes that may cause incidents or malfunctions, giving users the chance to intervene before a problem arises.

Researchers at Collège de France and Hong Kong Polytechnic University have recently designed a Na(Li)-ion battery that can monitor its own chemical and thermal state via a series of optical sensors integrated in its cells. This unique self-monitoring battery, presented in a paper published in Nature Energy, could provide greater safety and a more sustained efficiency compared to conventional battery technologies. ....
