In the second episode of "Battery Generation" we talk to Prof. #Stefano #Passerini, an Italian chemist. He has been researching #sodium as a #sustainable #battery #material for more than 10 years now. We asked him to display the possibility of #sodium #ion #batteries (#SIBs) replacing nowadays #lithium-based #energy #storage# systems in #EVs and #stationary #batteries.

Bam! In July 2021 the largest #Chinese #manufacturer of #lithium-#ion batteries #CATL ("#Contemporary #Amperex #Technology Co. Limited") unveiled its latest breakthrough technology by releasing its first generation of sodium-ion batteries (SIBs).

Based on a series of #innovations in the chemistry system, CATL’s first generation of SIBs has the advantages of comparatively high-#energy #density, fast-charging #capability, great low-temperature #performance and high-integration #efficiency, among others.

The #energy #density of CATL’s SIB cell can supposedly achieve up to 160Wh/kg, and the battery can charge in 15 minutes to 80% at room temperature. Moreover, in a low-temperature environment of -20°C, the sodium-ion battery has a #capacity retention rate of more than 90%, and its system integration #efficiency can reach more than 80%. These are impressive results when comparing to nowadays #lithium-ion #battery #performance numbers.

We asked our guest Prof. Dr. #Stefano #Passerini to take a stand regarding the latest #research findings on SIBs. What are the main differences concerning the #abundance of the used #materials, #sustainability, #recycling, #price, #energy #density and #safety #issues.
