Flexible, solid polymer electrolytes based upon high molecular weight poly(ethylene oxide) incorporating triethyl sulfonium bis(trifluoro sulfonyl) imide have demonstrated lithium conductivity at physiological temperatures. Cycling tests on a Li/electrolyte/LiFePO4 have been conducted showing stability for the charge and discharge capacity after the initial decay. Slipping has been observed, whereby the charge and discharge capacity are continuously mismatched by a constant amount over extended cycling. Work is underway to perfect the cell set-up as intra-electrode diffusion kinetics dominates the observed phenomena.
