Limiting global warming requires paradigm-shift discoveries in energy storage, leading to rechargeable batteries that give electric cars the desired 800-km range. The complementary use of synthesis and advanced characterization techniques in synergy with modelling have enabled the discovery of materials by design, which we apply here. We will discover nanomaterials and nanocomposites for long-lasting and inexpensive Sodium-ion batteries. We will combine computation with experiments to develop novel, inexpensive, NA-Super-Ionic-CONductor (NASICON) solid-electrolytes, NazZr2-yMySixP3-xO12, for safe solid-state batteries (SSB). By optimizing the composition and nanostructure of NaSICONs, we will decrease the operation temperatures of existing SSB from 200°C to ambient temperature. This synergistic approach is possible by bringing together the expertise of the PIs : NUS : high-throughput density functional theory; Softbond potentials for screening ion-transport, solid-state NMR. LRCS : synthesis, crystallography and electrochemistry; impedance spectroscopy and SSB manufacturing.
