A　strategy　for　growth　of　porous　Ni2GeO4　nanosheets　on　conductive　nickel　(Ni)　foam　with　robust　adhesion　as　a　high-performance　electrode　for　Li-ion　batteries　is　proposed　and　realized,　through　a　facile　two-step　method.　It　involves　the　low　temperature　hydro-thermal　synthesis　of　bimetallic　(Ni,　Ge)　hydroxide　nanosheets　precursor　on　Ni　foam　substrates　and　subsequent　thermal　transformation　to　porous　Ni2GeO4　nanosheets.　The　as-prepared　Ni2GeO4　nanosheets　possess　many　interparticle　mesopores　with　a　size　range　from　5　to　15　nm.　The　hierarchical　structure　of　porous　Ni2GeO4　nanosheets　supported　by　Ni　foam　promises　fast　electron　and　ion　transport,　large　electroactive　surface　area,　and　excellent　structural　stability.　The　efficacy　of　the　specially　designed　structure　is　demonstrated　by　the　superior　electrochemical　performance　of　the　generated　Ni2GeO4　nanosheets　including　a　high　capacity　of　1.8　m.A.hcm(-2)　at　a　current　density　of　50　mu　Acm(-2),　good　cycle　stability,　and　high　power　capability　at　room　temperature.　Because　of　simple　conditions,　this　fabrication　strategy　may　be　easily　extended　to　other　mixed　metal　oxides　(MxGeOy).
