How are negative electrodes made?
The manufacturing of negative electrodes for lithium-ion cells is similar to what has been described for the positive electrode. Anode powder and binder materials are mixed with an organic liquid to form a slurry, which is used to coat a thin metal foil. For the negative polarity, a thin copper foil serves as substrate and collector material.
Can a negative electrode be used as a lithium-ion battery material?
To be used as a lithium-ion battery material, it is, however, not enough that the material has a high electronic conductivity and a high surface area. A good negative electrode material also needs to undergo a reduction during the lithiation step and an oxidation during the subsequent delithiation step.
