Worked Solution & Example Answer:Which one of the following statements about lithium ion batteries is correct? A - VCE - SSCE Chemistry - Question 23 - 2022 - Paper 1
Step 1
B. During discharge, Li+ ions move towards the positive electrode.
Answer
This statement is correct. During the discharge phase of a lithium-ion battery, lithium ions ( ext{Li}^+) migrate from the negative electrode (anode) through the electrolyte towards the positive electrode (cathode). This movement of ions is crucial for the generation of electrical energy as the stored chemical energy is converted.
