Exothermic peaks in DSC

Make a list of the types of changes that can give exothermic peaks in DSC and DTA. Make a list of the types of changes that can give endothermic peaks in DSC and DTA. 

A silicon/disordered-carbon powder was applied as the negative electrode material in Li-ion batteries. The thermal characteristics of the Si/C electrode (with or without the electrolyte) were investigated by DSC [9]. Both lithiated (with capacity of 1120 mAh/g) and delithiated Si/C electrode powders showed exothermic peaks in DSC curves due to the reactions between the Li in the electrode and the SEI. The lithiated electrode caused much larger exothermic heat them the delithiated one, especitilly when they were mixed with the electrolyte.
