6 FAQs about [How to test the positive electrode material of lithium battery]

How does a lithium ion battery work?

The lithium-ion battery generates a voltage of more than 3.5 V by a combination of a cathode material and carbonaceous anode material, in which the lithium ion reversibly inserts and extracts. Such electrochemical reaction proceeds at a potential of 4 V vs. Li/Li + electrode for cathode and ca. 0 V for anode.

Why do lithium batteries have a strong oxidative power?

The cathode materials of lithium batteries have a strong oxidative power in the charged state as expected from their electrode potential. Then, charged cathode materials may be able to cause the oxidation of solvent or self-decomposition with the oxygen evolution. Finally, these properties highly relate to the battery safety.

How does a lithium ion battery stabilize a negatively charged cathode?
