Improving the stability of an organic battery with an ionic liquid-based plymer electrolyte

Artikel i vetenskaplig tidskrift, 2012

A gel polymer electrolyte based on the ionic liquid {N-butyl-N-methyl-pyrrolidiniumbis(trifluoromethanesulfonyl) imide (Py14TFSI) and lithium bis(trifluoromethanesulfony)imide (LiTFSI)} is shown to prevent the dissolution from an organic electrode. The composite cell shows high energy efficiency although poor cycle stability is exhibited at very high current density (10 C-rate).
