Polymer separator coated with organic-inorganic hybrid based lithium secondary battery manufacturing and performance evaluation |
| 초록 |
Polyethylene is used as LIB separator. But the ‘shutdown’ characteristic occurs due to the high current with the rise of temperature then the separator is torn. This creates a fire hazard. So separator must have thermal, mechanical strength and it has to well wetted by electrolyte. In this study, use organic material's flexibility and inorganic material's thermal, mechanical stability. So durability of the separator was given by organic-inorganic hybrid coating agent. That was used with LPSQ which is silane-based polymer and together with catechol functional group, that is coated with chemical bond at PE separator. It was confirmed that LIB using CA-LPSQ coated PE separator shows the performance and durability was improved. *This work was supported by Korea Institute for Advancement of Technology (KIAT) grant funded by the Korea Government (MOTIE) (P00008500, The Competency Development Program for Industry Specialist) *2021년 한국교통대학교 지원을 받아 수행하였음. |
