The present invention relates to a new lithium-doped Pernigraniline-based material, a method for the preparation thereof, its use in various applications, an electrode comprising said lithium-doped Pernigraniline-based material and its preparation method, a membrane comprising said lithium-doped Pernigraniline-based material and its preparation method, and an electrochemical storage system comprising said electrode.

Lithium-doped pernigraniline-based materials

The invention relates to a BA diblock or BAB triblock copolymer, in which the A block is a non-substituted poly-oxyethylene chain having a mean molecular weight that is no higher than 100 kDa, and the B block is an anionic polymer which can be prepared using one or more monomers selected from among the vinyl monomers and derivatives thereof, said monomers being substituted with a (trifluoromethylsulfonyl)imide (TFSI) anion. The invention also relates to the uses of such a copolymer, in particular for preparing an electrolyte composition for lithium metal polymer (LMP) batteries.

A cement suspension includes the following, in relation to the cement material: water (22-35% by weight); acetic acid (1-10% by weight); plasticizer (up to 8% by weight); and dispersant agent (0-2% by weight), having an apparent viscosity of 0.5-2 Pa&#xb7;s for the casting speed gradient. Pieces of cement that are prepared from the suspension and which can be used as electronic components are also disclosed.
