Learn MoreIn conventional liquid cells, single-crystal cathode materials have shown substantial advantages over polycrystalline counterparts, such as particle integrity, thermal and high-voltage stability, and better safety . However, single-crystal cathode materials have not been investigated yet in the solid-state battery system.
Researchers from Dalhousie University, working with the Canadian Light Source (CLS) at the University of Saskatchewan, have analyzed a promising new lithium-ion battery material: single-crystal electrodes. The results are remarkable.
Traditional batteries use electrodes composed of tiny particles made up of smaller crystal clusters. In contrast, the single-crystal electrode is a single, continuous crystal, making it far more resistant to mechanical stress and strain. Bond likened the difference to that between a snowball and an ice cube – the latter being much harder to crush.
Over time, these cracks lead to the material's gradual pulverisation, ultimately reducing the battery's performance and capacity. By contrast, single-crystal electrodes demonstrated remarkable resilience. Even after prolonged use, these electrodes exhibited minimal mechanical stress and appeared nearly identical to new cells.
Unlike traditional lithium-ion batteries, which develop extensive microscopic cracking in their electrode material due to repeated charging and discharging, the single-crystal battery exhibited minimal mechanical stress. The electrode material remained structurally intact, appearing nearly as pristine as a brand-new cell.
All-solid-state lithium-ion batteries (ASSLIBs) are receiving significant attention owing to their improved safety and energy density over liquid counterparts. However, single-crystal cathodes have never been investigated in ASSLIBs.
