Abstract:
An electrochemically active material includes an active phase that includes silicon, and at least one inactive phase having a Scherrer Grain Size of greater than 5 nanometers. Each inactive phase of the material having a Scherrer Grain Size of greater than 5 nanometers has a lattice mismatch to Li15Si4 of greater than 5%.
