Initiated Chemical Vapor Deposition of Ultrathin Polymer Coatings at Graphite Electrodes for Enhanced Performance in Li-Ion Batteries

The solid-electrolyte interphases (SEIs) that form in situ at Li-ion battery electrodes play a critical role in determining cell- and system-level characteristics, but may not contribute optimized performance. Power, cycle life, and safety are improved when the electrodes are deliberately modified w...

Description
Summary:The solid-electrolyte interphases (SEIs) that form in situ at Li-ion battery electrodes play a critical role in determining cell- and system-level characteristics, but may not contribute optimized performance. Power, cycle life, and safety are improved when the electrodes are deliberately modified with nanoscale, Li+-conducting coatings. Herein, we use initiated chemical vapor deposition (iCVD) to apply ultrathin (
