The　search　of　low-cost,　earth-abundant　and　high　electro-capacitive　electrode　materials　is　significant　for　the　practical　application　of　supercapacitors.　Here　we　introduce　a　simple　and　cost-effective　strategy　for　one-step　synthesis　of　self-supported　NixP　nanowires/Ni　hybrid　foam　electrodes　from　commercially　available　Ni　foams　via　low-temperature　thermal　phosphorization.　This　electrode　exhibits　superior　electrochemical　capacitive　performance　featured　by　an　ultrahigh-rate　performance　(0.36　C　cm(-2)　at　100　mA　cm(-2))　and　long　cycling　stability　(a　stable　capacitance　of　0.74　C　cm(-2)　at　20　mA　cm(-2)　for　5000　cycles),　which　benefits　from　the　good　electrical　conductivity　of　NixP　nanowires　active　materials　on　Ni　foam　and　one-dimensional　structure　for　NixP.　This　work　demonstrates　a　facile　and　effective　avenue　to　prepare　a　cheap　and　efficient　super-capacitive　electrode　for　the　practical　application　of　supercapacitors.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
