Final answer:
The events that impacted the demand, supply, and price of lithium and nickel include the appearance of NiMH batteries, the passage of the Mercury Containing and Rechargeable Battery Act, the exports of scrap metal, improvements in PAL processing technology, the American Recovery and Reinvestment Act, and the introduction of plug-in electric vehicles.
Step-by-step explanation:
The events listed have impacted the demand, supply, and price of lithium and nickel. The first appearance of NiMH batteries in consumer goods in 1989 increased the demand for nickel, as these batteries contain nickel.
The passage of the Mercury Containing and Rechargeable Battery Act in 1996 facilitated the recycling of NiCd batteries, which impacted the supply of nickel. Large exports of scrap metal from Russia between 1996-1998 also influenced the supply of nickel.
The improvements in PAL processing technology in 2000 affected the supply of nickel, as this technology is used in the processing of nickel.
The American Recovery and Reinvestment Act in 2009, which included spending on rechargeable battery technology, impacted the demand for lithium as it encouraged the development of electric vehicles.
The introduction of the first plug-in electric vehicles in 2010, such as the Nissan LEAF and Volt, which use Li-ion batteries, further affected the demand for lithium.
