Ethylene open-circuit potential

Kawaietal. [42] investigated poly (rra 5 -l,2-di(2-thienyl)ethylene), a P(T) derivative, as a cathode material for a secondary Li battery, although they did not actually construct a battery. An open circuit potential and a coulombic efficiency as high as 3.8 V and 99% (over 100 cycles) respectively were claimed in liquid, PC- or nitrobenzene-based electrolytes.

Figure 18 depicts a galvanostatic transient experiment, showing the rate response to an applied current step (+300 aA for 120 min) during ethylene oxidation on an Ir02 catalyst/ The evolution of the catalyst film potential with respect to the reference electrode, Kwr, is also given. Initially the circuit is open (/ = 0) and the unpromoted catalytic rate is very slow. At f = 0 a constant current (/ = +300 tA) is applied between...
