PME Distinguished Colloquium Series Seminar - Dr. Lynden Archer

Electrodeposition is a more than two centuries old process for creating coatings of metals and particles on electrically conducting substrates. The presentation addresses a long-standing technical problem associated with the propensity of all metals to form non-uniform, rough/dendritic electrodeposits with crystal structures that can be completely different from those observed in the bulk. The search for solutions has re-emerged in recent years as a priority research direction because it is understood that poor control of metal crystallization and plating at rechargeable battery anodes is an impediment to practical low-cost batteries. The presentation will summarize results from studies over the last decade, which have shown that recharge of any metal anode requires reversible nucleation and growth of crystalline structures with symmetries that are rarely, if ever, consistent with those dictated by the fields inside a closed battery cell. This means that the interfacial products from spontaneous electrode growth reactions in a battery cell are, in most cases, fundamentally incompatible with Requirements for achieving the very high levels of reversibility required for achieving cost-effective and long-duration storage.
