Batteries are now used in very high volumes of everyday applications such as powering mobile phones, laptops and other portable electronic devices. These batteries are promising candidates for sustainable energy storage, although their use in high energy density applications, like powering electric vehicles, is still a challenge. A key limitation of the battery performance is the structural instability of battery materials with continuous usage and increased energy density requirements. Our central aim is to crystallographically and microstructurally engineer battery materials, such as electrodes, solid-electrolytes, in order to enhance energy storage capacity and lifespan. In our group, we use martensite crystallographic theory, phase-field and phase-field crystal methods, to design a new generation of battery electrodes—which offers minimum volume changes, enhanced conductivity and longer lifespans.
