The formation of lithium dendrites represents one of the main issues in the use of lithium anode for rechargeable batteries. To block their growth a possible solution is to increase the Young’s modulus of the electrolytes by creating hybrid ceramic-polymer systems [1]. Our approach is the realization of small polymer-chain-grafted nanoparticles (NP) as a branched structure filler which gives a better chemistry affinity with the polymer matrix and increases its mechanical resistance [2]. In particular, here we investigate PEO5K-grafted TiO2 NP as a filler for PEO4M/ LiTFSI-based Solid Polymer Electrolyte.
