Nanoscale oxide-based negative electrodes are of great interest for lithium ion batteries due to their high energy density, power density and enhanced safety.
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 performance of the synthesized composite as an active negative electrode material in Li ion battery has been studied. It has been shown through SEM as well as impedance analyses that the enhancement of charge transfer resistance, after 100 cycles, becomes limited due to the presence of CNT network in the Si-decorated CNT composite.
Analysis of the electrochemical properties of the synthesized Cu-Si nanocomposite reveals great promise for use as a lithium-ion battery anode. Table 3 summarizes recent advancements in the preparation of nano-silicon and its composites using molten salt electrolysis and various established technologies.
Electrode materials consisting of Fe oxides are a possible solution because Fe has the fourth highest Clark number and low toxicity. Since the commercialization of lithium-ion batteries (LIBs), various Fe oxides such as FeOOH, (1−11) LiFeO 2, (12−15) Fe 2 O 3, (6,16−22) and Fe 3 O 4 (6,18,23−25) have been proposed.
