Abstract
A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode, a porous insulating layer, and nonaqueous electrolyte. The porous insulating layer is interposed between the positive electrode and the negative electrode. The nonaqueous electrolyte is contained at least in the porous insulating layer. The mixture layer of the positive electrode and the porous insulating layer each include a structure retainer.
Claims8
A nonaqueous electrolyte secondary battery, comprising:
- a positive electrode having a mixture layer which contains an active material in which lithium ions are electrochemically intercalatable and deintercalatable;
- a negative electrode having a layer which contains an active material in which lithium ions are electrochemically intercalatable and deintercalatable;
- a porous insulating layer interposed between the positive electrode and the negative electrode;
- and
- nonaqueous electrolyte contained at least in the porous insulating layer,
- wherein the mixture layer of the positive electrode includes a structure retainer, and
- the porous insulating layer includes a structure retainer or is formed by a structure retainer.
