Abstract
The electrode–electrolyte contact issue within the composite electrode layer is a grand challenge for all-solid-state Li batteries. In order to achieve cycling performances comparable to Li-ion batteries based on liquid electrolyte, the aforementioned solid–solid contact not only needs to be sufficiently thorough but also must tolerate repeated cycling. Simultaneously meeting both requirements is rather challenging. Here, we discover that epitaxy may effectively overcome such bottlenecks even when the electrode undergoes repeated phase transitions during cycling. Through epitaxial growth, the perovskite Li0.33La0.56TiO3 solid electrolyte was found capable of forming atomically intimate contact with both the spinel Li4Ti5O12 and rock-salt Li7Ti5O12. In contrast to conventional expectations, such epitaxial interfaces can also survive repeated spinel-to-rock-salt phase transitions. Consequently, the Li4Ti5O12–Li0.33La0.56TiO3 composite electrode based on epitaxial solid–solid contact delivers not only a rate capability comparable to that of the surry-cast one with solid–liquid contact but also an excellent long-term cycling stability.
