New article published in Journal of Materials Chemistry A on high performance Mo(C,N,O)x Li-ion battery anodes

New article published in Journal of Materials Chemistry A on high performance Mo(C,N,O)x Li-ion battery anodes. Using a continuous wet-chemical process process called a microjet reactor, we combined ammonium heptamolybdate with para-phenylenediamine, tweaking the mix to get just the right results. After applying thermal annealing, we obtained Mo(C,N,O)x with stacking defects embedded in a carbonaceous […]
