The lithium quantity can also be optimized to increase the capacity. The theoretical capacity of NMF is calculated with the assumption that Li and NMF are precent at a 1:1 ratio. The capacity could increase considerably if even 10% more lithium could be stored in the structure in a stabile manner. Several articles highlight such work, owing to higher observed specific capacities
. Nonetheless, NMF requires still considerable research before it could become a competitive material on the market. Mainly its stability under repeated cycles needs to be improved, along with the ability to deliver high amounts of current rapidly.
