Title: FLEXIBLE SECONDARY BATTERY AND ELECTRONIC DEVICE
Abstract:
Provided is a flexible secondary battery which is capable of achieving flexibility and high capacity at the same time. This flexible secondary battery is composed of a lithium ion secondary battery which has flexibility and is configured to comprise a positive electrode and a negative electrode, at least one of which has an active material layer containing a softening agent, and an Mn-containing active material of the positive electrode. The internal pressure reduction degree of the secondary battery is 100-1,000 Pa.
