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 (15[1])won the 2019 Nobel Prize in Chemistry for developing one type of these devices (-5[1])where a cation is intercalated into a graphite matrix. (15[1])(*) Sulfuric acid (10[1])is used as an electrolyte in the lead-acid type of (10[1])these devices. (10[1])Nickel and cadmium name (10[1])a common type of, for 10 points, what devices whose “lithium-ion” variant is rechargeable? ■END■
