LITHIUM ION SECONDARY BATTERY AND METHOD FOR PRODUCING SAME |
摘要 |
A lithium ion secondary battery includes: a positive electrode including a positive electrode substrate, and a positive electrode material mixture layer carried on the positive electrode substrate; a negative electrode including a negative electrode substrate, and a negative electrode material mixture layer carried on the negative electrode substrate; a separator; a non-aqueous electrolyte including a non-aqueous solvent that contains a carbonic ester, and a solute dissolved in the non-aqueous solvent; and a porous film bonded to a surface of at least one of the positive electrode and the negative electrode. The porous film includes an inorganic filler and a film binder, and the solubility parameter of the film binder is different from the solubility parameter of the non-aqueous solvent by 1 or more. |
