A typical LIB consists of a positive electrode (cathode), a negative electrode (anode), a separator, and an electrolyte. The positive and negative electrodes usually are made up of current collectors, active materials, conducting additives, and polymer binders. The separator is a porous polymer membrane and an electronic insulator sandwiched between the …
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.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
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.
In this review, porous materials as negative electrode of lithium-ion batteries are highlighted. At first, the challenge of lithium-ion batteries is discussed briefly. Secondly, the advantages and disadvantages of nanoporous materials were elucidated. Future research directions on porous materials as negative electrodes of LIBs were also provided.
In such electrode technology, the negative precharge is set to a higher level than that of the sintered technology to increase the electrode conductivity in the discharged state due to the larger distance between the steel strip and the active material.
For the negative electrode, usually a carbonaceous material capable of reversibly intercalating lithium ions is used. Depending on the technical and process demands, several different carbon materials and configurations (e.g., graphite, hard carbon) may be used.
