Lithium metal battery systems (LMBs) are being sought as an ultimate replacement to lithium ion batteries (LIBs), potentially increasing the cell energy by over fifty percent due to the high capacity and low voltage of the metal anode. Analogous improvement in energy is possible with sodium metal batteries (NMBs) and with potassium metal batteries (KMBs), where existing ion insertion anodes can be replaced by plating/stripping metal. However, in all three cases safety and performance are compromised by an unstable solid electrolyte interphase (SEI) that consumes metal ions and electrolyte, and ultimately leads to dendrites.
This presentation provides a series of case studies derived from the group's LMB, NMB and KMB liquid and solid-state research on the microstructural design principles that provide for long-term cycling and fast-charge stability of metal anodes. The approaches may be categorized as the following:
- design of plating/stripping supports and templates with tuned geometry and functionality;
- design of secondary interlayers placed between the metal anode and the separator; and
- design of multifunctional hybrid separators to replace the conventional polymer separators employed with LIBs.
Hosted by Professor Lee Lynd.
