Hello !

I fabricated lithium-ion half cells (silicon anodes and lithium metal) with LP30 +2% FEC as the electrolyte solution and tested galvanostatically at C/10 rate. After 5 cycles, there was a rest for 10 hours and then I took strange curves at delithiation state (C/10 rate). Is there any idea about that ?

P.S

I would like to mention that the temperature of the lab is stable at around 23oC.

I have also noticed that sometimes, high c-rates "recover" the curves to initial behavior.

comments please !

Thank you for your time !
