Novel advance for smart batteries testing and monitoring

The aim of this thesis work is to contribute to the technological advancementof energy storage systems, especially batteries, in terms of efficiency and safety. The thesis to be demonstrated argues that on the one hand, the possibility of testing electrode materials with a more performing and versatile system than those present in the state of the art allows to reach a level of characterization and understanding of the working behaviour of these materials higher than the current state. On the other hand, the use of economic and at the same time effective sensors makes it possible to improve the production process of electrochemical cells and to monitor their state of health during their useful life, ultimately achieving the desired high level of reliability. The main activity of this work consists of three different experimental phases aimed at improving the performance of an instrument for testing the electrodes in rechargeable batteries, as well as the search for an economic and high-performance sensor to detect electrolyte losses in the production process of lithium-ion batteries and the study of an innovative sensor that can be integrated into the electrochemical cell that can closely monitor its stability by intercepting any malfunctions.
