Heat treatment of highly crystalline graphite TIMREX® SLX50 at temperatures above 1200 °C in an inert gas atmosphere resulted in a significant increase of the irreversible capacity, which is observed during the first electrochemical lithium inserti

This paper discusses the interrelated phenomena of solid electrolyte interphase (SEI) formation and the irreversible charge consumption which occurs during the first cycle of a graphite electrode, as well as their relevance to the cycling stability o

Cycling of graphite in lithium-ion batteries is reversible except for the first-cycle, where some charge is “lost” due to irreversible side reactions. The irreversible charge loss of different TIMREX ® graphites was found to be a linear function
