Abstract
Embodiments described herein relate generally to electrochemical cells having semi-solid electrodes that have damage tolerance, and in particular, are tolerant to physical damage due to short circuit, crushing, or overheating. In some embodiments, an electrochemical cell includes a positive electrode, a negative electrode and an ion-permeable membrane separating the positive electrode and the negative electrode. At least one of the positive electrode and the negative electrode can include a semi-solid ion-storing redox composition which has a thickness of at least about 250 μm. The electrochemical cell can have a first operating voltage in a first planar configuration and a second operating voltage in a second non-planar configuration such that the first operating voltage and the second operating voltage are substantially similar. In some embodiments, the electrochemical cell has a bend axis such that the electrochemical cell is bent about the bend axis in the second non-planar configuration.
