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. John Goodenough won the 2019 Nobel Prize in Chemistry for developing one type of these devices where a cation is intercalated into a graphite matrix. (*) Sulfuric acid is used as an electrolyte in the lead-acid type of these (10[1])devices. (10[1])Nickel and cadmium (10[1])name a common type of, for 10 points, what devices whose “lithium-ion” variant is rechargeable? ■END■
