Chemistry & Technology · Part 3 of 4
3 exam-style questions with model answers, plus 4 quick multi-choice questions — every question on this part of the standard, grouped by the 1 page of notes they come from.
Write a full answer before you reveal the model one. That comparison is where the learning happens.
Describe the three properties of lithium that make it suitable for use in batteries, and give the half equations occurring at each electrode during discharge.
Explain why lithium-ion batteries use a graphite electrode rather than lithium metal, and link this to the rechargeability of the battery.
Evaluate how chemistry has influenced the development of the lithium-ion battery, and discuss the constraints the chemistry continues to impose on its use in New Zealand.
