A: There are iron, magnesium, calcium, silicon and so on.
2. In the potassium hydroxide solution, what is the effect on the battery performance when the lithium hydroxide content is too much?
Answer: When the content of lithium hydroxide is too high, lithium ions can enter the lattice of the positive active material to form an inert compound called lithium nickelate, which affects the progress of the electrochemical reaction and deteriorates the performance of the electrode.
