Self-healing batteries - Do they exist? Prof. Berecibar | Battery Podcast

#everlasting #batteries #sensors

#Self-#healing #materials have the ability to automatically #repair damages to themselves without any external diagnosis or #intervention. Soon, they could be used in #battery #electrodes as well! This would impact the entire #battery world - since everlasting #cells definitely change the business for nearly every #manufacturer.

Prof. Dr. #Maitane #Berecibar is an expert for self-healing cell #properties and battery sensors. She is the head of the Battery #Innovation Center in the #MOBI research group at #Vrije #Universiteit #Brussel (#VUB). Her expertise of the Battery Innovation Center includes emerging battery #technologies, battery manufacturing, self-healing properties, sensor #integration, #modeling activities (#electrochemical, #thermal, #electrical, #lifetime), #cooling #system development, #second #life and safety. And that is what she is talking about.

The advantages of self-healing batteries and sensors are obvious: Very #stable, #sustainable, long-living, #smart and #safe batteries that provide valuable data for a secondary life. Sounds wonderful! But, Prof. Berecibar is not afraid of hiding the technology's downsides: Right now, scientists are still developing concept lab cells, that are yet quite #expensive, #complex to build and #difficult to understand.

One of the most significant questions for the battery industry remains unclear, though Is it possible to #scale up self-healing battery #production while implementing life-time prolonging properties to each and every existing cell chemistry, even individually? And, why would a #battery manufacturer actually consider selling "#forever batteries" in the first place (serious question!)?
