The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
Lithium metal batteries use metallic lithium (Li) as the negative electrode and a combination of different materials such as iron disulfide (FeS2) or MnO2 as the positive electrode.
The electrodes are the heart of the battery where all the electrochemical reactions occur. Testing of the electrodes prior to battery assembly provides insights into their composition, morphology, and electrochemical performance.
