1. A dynamic battery comprising:
- a positive electrode, a negative electrode, and a separator separating the positive electrode from the negative electrode, at least one of the positive electrode or the negative electrode including a primary electrode material and a dynamic electrode material different from the primary electrode material, the dynamic electrode material being activatable to change a power state of the dynamic battery,the dynamic battery configured to operate in a standard operating mode during which the dynamic battery supplies power to an external circuit and ion exchange for the dynamic battery occurs primarily across the primary electrode material relative to the dynamic electrode material, and configured to operate in an activated operating mode in response to an external stimulus being applied to activate the dynamic electrode material while the dynamic battery supplies power to the external circuit, the activated operating mode causing an increase in discharge capacity of the dynamic battery relative to the standard operating state.

Abstract
Techniques for dynamically changing internal state of a battery are described herein. Generally, different battery configurations are described that enable transitions between different battery power states, such as to accommodate different battery charge and/or discharge scenarios.
