Abstract (en)
[origin: WO2018145747A1] The invention relates to methods for producing redispersible particles based on silicon particles and polymers, characterised in that a) mixtures containing silicon particles with average particle diameters d50 of > 600 nm, one ore more polymers containing functional groups selected from the group comprising carboxyl-, ester-, alkoxy-, amide-, imide- und hydroxy-groups, as well as one or more solvents are dried; and subsequently b) a thermal treatment is carried out at a temperature of 80°C until below the decomposition temperature of the polymers.
