The performance of a battery depends on many factors amongst which the most critical are the electrode materials and their structural evolution upon cycling while in contact with the electrolyte. That is to say, whether the electrode material reversibly ''breathes'' or not upon each cycle without losing its structural integrity.

reference electrode and a large counter electrode of Li xMn 2O 4.We believe that the use of this counter electrode, with a mass some 20 times that of the working electrode, and an initial composition about Li 0.5Mn 2O 4, rather than an inert material, was quite impor-tant. It allows the cell to cycle reversibly, whereas the use of some
