Definitions
- the present invention relates generally to the field of electrical energy storage in rechargeable secondary batteries of the Li-ion type. More specifically, the invention relates to a composition capable of being used as a coating for a separator.
- Lithium-ion batteries also have a separator placed between the cathode and the anode.
- the separators must have low thicknesses, sufficient mechanical and temperature resistance, good electrochemical resistance to the voltages to which they are exposed, optimal affinity for the electrolyte and more generally allow excellent ionic conductivity.
- PVDF Poly(vinylidene fluoride)
- PVDF poly(vinylidene fluoride)
- its derivatives are of interest as a polyolefin separator coating, for their electrochemical stability, and for their high dielectric constant which promotes the dissociation of ions and therefore conductivity.
- separators based on PVDF copolymers onto which side chains including hydrophilic units are grafted.
- the invention therefore aims to remedy at least one of the disadvantages of the prior art.
- the present invention provides a composition
- R is selected from the group consisting of -NHC(CH3)2CH2C(O)CH3 or -OR' with R' selected from the group consisting of H and Ci-Cis alkyl optionally substituted by one or more group(s) -OH or a five- or six-membered heterocycle comprising at least one nitrogen atom in its cyclic chain, characterized in that the difference between the melting temperature and the crystallization temperature of said composition is greater than or equal to 40°C.
- the melting temperature and the crystallization temperature are determined according to ASTM D3418.
- the present invention provides a composition having a good compromise between different properties such as adhesion, conductivity and thermal stability when it is used in the implementation of compositions for separator.
