Novel high capacity anode material for Li-ion batteries: hydroxylamine hydrochloride

Researchers from Ningbo University in China report the first use of hydroxylamine hydrochloride (H3NOHCl) as anode material for lithium-ion batteries in a paper in the Journal of Power Sources. Electrochemical testing shows that H3NOHCl with particle size of 4–12 μm can deliver an initial charge capacity of 1018.6 mAh g−1—much higher than commercial graphite.

After 30 cycles, the reversible capacity of the material can be kept at 676.1 mAh g−1 at 50 mA g−1. Up to 50 cycles, H3NOHCl still maintains a lithium storage capacity of 368.9 mAh g−1. Even cycled at 200 mA g−1, H3NOHCl can deliver a charge capacity of 715.7 mAh g−1.

The team concluded that H3NOHCl has high lithium storage capacity, excellent cycling stability and outstanding rate performance.

By simply looking at its chemical composition, it seems like this new anode material would also be much cheaper than commercial graphite. Wonder how soon this material could be introduced into the market.
