What is it about?

The objective of this study is to propose a complete reliability model that predicts the cycle life of all-solid-state thin film microbatteries in application conditions, integrating a large number of operational parameters as input data, including the expected failure rate as a statistical feature. These microbatteries are intended to a wide range of new markets and applications: smart cards, battery-assisted RFID tags, wireless sensor networks, and multiple advanced healthcare applications

Why is it important?

Because of their recent development, all-solid-state microbattery technologies have been the topic of only few reliability studies, which mostly deal with operating characteristics, failure mechanisms,and capacity loss after a reduced number of cycles

Perspectives

This study was very interesting because it led to the development of a predictive cycle life calculation tool, integrating the possibility for the user to consider different operating conditions, as well as a statistical dimension through the failure rate determination
