Round 3: Tossup 4

The capacity of these devices is proportional to an expression raised to the dimensionless constant k according to one formulation of Peukert’s (“POY-kert's”) Law. S•S•Es such as L•L•Z•O are gaining traction to be utilized in one form of these devices, but remain challenged by dendrite formation. (15[1])John (15[1])Goodenough won the 2019 Nobel Prize in Chemistry for developing one type of these devices where a cation is intercalated into a graphite matrix. (15[1])(*) Sulfuric acid is used as an electrolyte in the lead-acid type of these (10[1])devices. Nickel and cadmium name a common (10[1])type of, for 10 points, what devices whose “lithium-ion” variant is rechargeable? ■END■
