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.
