Due to their high specific energy, efficiency and long cycle life, lithium-ion batteries are very attractive for energy storage and have been applied in many fields since their commercialization.1 Nevertheless, commercialized batteries are not perfect yet and suffer from safety issues. Moreover, achievable specific capacities are still not high enough to apply these batteries to future application fields like electric vehicles or in conjunction with renewable energy sources.2Thus, the design of new electrode material is necessary: Nano-sized metal chalcogenide particles are promising candidates for anode materials. Due to the low electronic conductivity and surface related structural changes of these particles, a conductive coating on the surface of the particles is needed.3Herein a new approach for the preparation of a homogeneous graphitic coating has been introduced using blockcopolymers, which can be grafted onto the nanoparticle surface followed by pyrolysis of the hybrid material affording graphitic structures on the particle surface.4By electrochemical characterization of the prepared material the positive influence of the graphitic coating could be proved involving enhanced battery performance compared to non-coated reference particles.References (1) Scrosati, B.; Garche, J.
