| titleOfInvention |
Composition for porous membrane for lithium ion secondary batteries, porous membrane for lithium ion secondary batteries, and lithium ion secondary battery |
| abstract |
An object of the present invention is to provide a technique for trapping transition metal ions such as cobalt ions eluted from a positive electrode active material in a secondary battery to prevent precipitation of transition metals from a negative electrode. According to the present invention, a non-conductive particle and a binder are included, wherein the binder contains a polymer A containing an aliphatic conjugated diene monomer unit in a ratio of more than 85 mass% and a (meth)acrylic acid ester monomer unit in an amount of 60 mass% The composition for a porous film of a lithium ion secondary battery is provided which contains the polymer B contained in the above ratio, and ratio of the content of the said polymer A with respect to content of the said polymer B is 0.2 or more and 9.0 or less on a mass basis. |
