Correlation between conductivity the components of electrodes mass of Li batteries and electrochemical properties of these electrodes and Li batteries based on these electrodes have been investigation. The various types of the graphene and the graphite have been used as conductive additives for cathodes (positive electrodes). Various types of sulfide, manganese dioxide, lithium manganese spinel, and sulfides have been used as active materials of electrodes of Li batteries. The conductivity of powder materials have been investigated using the innovating non-contact non-destructive electromagnetic method. Impedance, galvanic cycling and current-voltage characteristics of the electrodes have been investigated.
Melanin is a biological organic polymer and has semiconductor properties. The structure of organic semiconductors, including melanin, determines the mechanism of their conductivity, electrical, and catalytic properties. Research the properties of melanin, which are synthesized on the basis of innovative technologies developed by Sunoil-Agro, confirms the innovating prospects for using melanin with goal to modify electrodes of Li-ion batteries. Results of investigation and developed the method modification the cathode materials of Li-ion batteries are presented in this article. The goal is to increasing the energy and power characteristics of LiMn2O4-based cathodes as a result of their modification with melanin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
