An over view of Tin-polypyrrole structured anode for lithium-ionbatteries

lithium-ion batteries are one of most important type of energy storage systems that have been investigated extensively, owing to their advantages of environmental friendliness, high energy density and long cycle life. Tin (Sn) based materials as anode for LIBs has attracted most of attentions due to its high specific capacity; however pulverization and poor cycling hinders its vast application. Conductive polymers can buffer the strain resulting from volume change in lithium ion insertion and extraction process. polypyrrole as one of the conductive binder not only can improve electrons transportation but also acts as a dispersant and prevent agglomeration Tin-polypyrrole based anodes has been prepared by both chemical and electrochemical pathways with different kind of morphologies. This composites are able to reduce above mentioned problems.to cater rapid development in Sn-based anodes, here the structural design principles and overall compare of similar compositions will be presented; to facilitate future practical implementations in next generation of Tin-polypyrrole anodes.
