Electrode materials for lithium-ion batteries
The negative electrode is one of the key components in a lead-acid battery. The electrochemical two-electron transfer reactions at the negative electrode are the lead oxidation from Pb to PbSO4 when charging the battery, and the lead sulfate reduction from PbSO4 to Pb when discharging the battery, respectively.
Initially PVDF was the main binder employed for negative electrodes1 but now the use of SBR has become more popular.2 SBR is now used in almost 70% of all batteries. Compared to PVDF, SBR provides better battery properties. For example: more flexible electrode; higher binding ability with a small amount; larger battery capacity; and higher cyclability.
Usually commercial cells do not have a reference electrode, so the real-time negative electrode voltage control method cannot be applied directly to such cells.
