Packet 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 (15[1])in one form of these devices, but remain challenged by dendrite formation. (15[4])John (15[3])Goodenough (15[1]-5[1])won the 2019 (15[1])Nobel (15[1])Prize (15[1])in Chemistry (15[2])for developing one type of these devices (15[2]-5[1])where a cation is intercalated (15[1])into a graphite matrix. (15[2]-5[2])(*) Sulfuric acid (10[2])is used as an electrolyte in the (10[1])lead-acid (10[2])type (10[1])of (10[1])these (10[2])devices. (10[7])Nickel and (10[1])cadmium (10[1])name (10[2])a common (10[1])type (10[2])of, for 10 points, what devices (10[1])whose “lithium-ion” (10[1])variant is rechargeable? ■END■ (10[1])
