Matrix and Cathode Deterioration

An aim of the evolving matrix recipes directed at 40 000 h operation is to minimise the slow progressive dissolution of cathode NiO by the 

MTU describes a double-layer cathode a first layer of lithium-treated NiO and a second layer of cerium-activated lithium cobaltite. The objectives are reduced polarisation resistance and longer life. No performance details are given. 

From the foregoing it can be seen that the cathode is once again the more difficult electrode structure. Optimisation is proceeding, in parallel with initial operating experience.
