Abstract
In a secondary battery wherein a positive electrode active material layer 2 and a negative electrode active material layer 3 are allowed to face each other via an electrolyte solution 1, there is used, as the electrolyte solution 1, a basic solvent containing a halogenated polyolefin dissolved therein.
Claims22
An electrolyte solution consisting of a basic solvent containing an alkali metal salt and a halogenated polyolefin both dissolved therein.
A secondary battery using an alkali metal ion as a charge carrier and having a structure in which a positive electrode and a negative electrode are adjacent to each other via an electrolyte solution, in which secondary battery the electrolyte solution consists of a basic solvent containing an alkali metal salt and a halogenated polyolefin both dissolved therein.
A secondary battery having a structure in which a positive electrode layer and a negative electrode layer are laminated via a separator and a liquid electrolyte is allowed to be present between the positive electrode layer and the negative electrode layer, in which secondary battery the liquid electrolyte is a plastisol containing an electrolyte salt.
A process for producing a secondary battery, which comprises:
- a step of laminating a positive electrode layer and a negative electrode layer via a separator,
- a step of introducing a plastisol containing an electrolyte salt, between the positive electrode layer and the negative electrode layer,
- a step of applying a voltage between the positive electrode layer and the negative electrode layer to heat part of the plastisol, and
- a step of cooling the plastisol.
