Two new fast-charging Li-ion battery papers published

We recently published two papers on fast-charging Li-ion batteries in <15 minutes! The first, published inĀ J. Mater Chem A [link], performs operando video microscopy to study Li plating on the graphite anode surface. We study Li nucleation, growth, re-intercalation, and dead Li formation, identifying electrochemical signatures of plating. In the second, published in Adv. Energy Mater. [link], we introduce a new strategy to avoid Li plating during fast charge, by coating the graphite anode surface with a solid electrolyte material. This eliminates natural SEI formation, reducing SEi impedance by 75%, and enables 500 cycles of 4C (15 minute) fast charging without Li plating.
