[EN] Mixing of aqueous suspensions of delaminated NiMn layered double hydroxide (LDH) and graphene oxide leads to the instantaneous precipitation of a hybrid material that after calcination under inert atmosphere at 450 degrees C leads to Ni6MnO8 nanoparticles deposited on larger reconstituted graphene sheets. This material exhibits electrical conductivity similar to graphite, superparamagnetism and can be used as an anode for Li-ion batteries. A maximum capacity value of 1030 mAh g(-1) was found during the first discharge, and capacity values higher than 400 mAh g(-1) were still achieved after 10 cycles. The methodology used here should allow the preparation of a large variety of hybrid graphene-metal oxide materials starting from other LDHs in which the properties derived from both constituents coexist.This work has been supported by the EU (ERC SPINMOL Advanced Grant), the Spanish MCINN with FEDER cofinancing (Project Consolider-Ingenio in Molecular Nanoscience CSD2007-00010, CTQ-2008-06720, and CTQ 2009-15896) and the Generalitat Valenciana (PROMETEO program).
