Poly(vinyl imidazolium) based-binders for high performance lithium-ion battery |
초록 |
A series of poly(ionic liquid)s (PILs) were used as binders for lithium-ion battery (LIB) with a cathode to explore their role and benefits in a model electrochemical energy storage system. The PILs are imidazolium-based and bear different main chain structures and alkyl substituents. The results nicely show that PILs both improve the cycling stability and specific capacity. When carefully designed, they especially exhibited a usually high electrochemical stability against oxidative conditions (=4.0 vs. Li/Li+). It is found that the PIL binders together with carbon additive form very effective Li+ and electron conducting pathways in the electrode. These finding illustrate that binder with carefully designed chemical structures can have a high potential to improve the electrochemical performance even of current rechargeable battery systems. A better Li+ and electron conduction is however of general importance for a wide spectrum of electrochemical devices. |
