In Figure 8 we can see that the half-cell measurement of the cycled alloy straight out of the spent battery lost about 5% of the initial capacity, showing that most of the alloy capacity remains even if the battery has passed the end-of-life criteria caused by electrolyte dry-out. The balled-milled and washed alloys showed the best performance.
