The positive electrode or cathode is typically made from lithium-cobalt oxide or lithium iron phosphate, while the negative electrode or anode is generally made from graphite [180]. The performance of lithium-ion batteries strongly depends on the insertion electrode materials.
These experiments were successful, and by 1983 Thackeray was building batteries with lithium manganese oxide cathodes. There were now two possible cathodes for a practical lithium-ion battery: Goodenough''s lithium cobalt oxide (LCO) and Thackeray''s lithium manganese oxide (LMO). But a material that could replace the hazardous lithium metal
Types of Lithium-ion Batteries. Lithium-ion uses a cathode (positive electrode), an anode (negative electrode) and electrolyte as conductor. (The anode of a discharging battery is negative and the cathode positive (see BU-104b: Battery Building Blocks). The cathode is metal oxide and the anode consists of porous carbon. During discharge, the

In Li-ion batteries, cobalt is available in the +3 oxidation state. Cobalt leaching has been studied in MFCs using a cathode with LiCoO 2 particles adsorbed onto it. Reduction of Co (III) to Co (II) in LiCoO 2 particles caused by electron flow from the electroactive biofilm-anode led to the release of Co (II) into the catholyte .
Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid, and is commonly used in the positive electrodes of lithium-ion batteries. 2 has been studied with numerous techniques including x-ray diffraction, electron microscopy, neutron powder diffraction, and EXAFS.

Mitchell et al. developed the carbon nanofibers electrode for lithium–oxygen batteries and achieved a discharge capacity of 7200 mAh g −1 and of higher gravimetric energy density, which is almost four times higher compared with LiCoO 2 cathode for LIBs.

Cobalt is present as Co (III) in these batteries in the form of lithium cobalt oxide (LiCoO2). When LiCoO 2 particles were coated on MFC cathode, Co (III) was reduced to Co (II), which caused the leaching of Co (II) into the catholyte (Huang et al., 2013).
