Abstract :
6.2.2.3. Other Models.
In addition to Besenhard's model, the other models were mainly 
modifications developed from the original Peled's concept for lithium
electrode passivation, with surface reaction as the major process, and 
emphasis was placed upon the composition and structure of the 
precipitated film or the interaction between the precipitated products 
and the bulk electrolyte components.

6.2.2.4.  The Mystery of Exfoliation.
However, all ofthe above models that recognize surface reactions as the 
film formation path were strongly challenged by the results of the 
comparative studies carried out by Chung et al. To explore the origin of 
graphite exfoliation, they used a series of model carbonates to study 
their cointercalation behavior with graphites and found a correlation 
between the stereo hindrance of the solvent molecules and the behavior 
of the graphite anodes in the electrolytes based on them.
