a Severe structural collapse of a conventional SiO electrode during lithiation and delithiation. The huge volume changes of SiO particles lead to the cracking at the particle level and electrode level. The blue lines represent the electrode binder. b The integrated structure of a SiO electrode during cycling enabled by a supremely elastic GPE, which serves as an intra-electrode cushion (orange) to reduce the thickness increase and cracking during lithiation and to help retrieve the electrode structure during delithiation.
