Innovative Non-Destructive Electromagnetic Method for Testing and Investigation: The Basis of New Technologies for Production High-Energy Batteries

The goal of this investigation is connected with wishes to use the melanin for formulating the solid polymer electrolyte without the binder for Li batteries. Nature and properties of solid polymer electrolyte of the Li batteries is an important factor for ensuring the properties of Li batteries. For successful optimization the properties of Li batteries the following list includes the important requirements for the polymer electrolyte: high conductivity in wide operating temperature, chemical stability and no ignition at under high temperature - even more than 1000C, low impedance of interface between electrode and solid polymer electrolyte, special design of system - the solid polymer electrolyte in porous structure of electrode. For developing the solid polymer electrolyte without the binder we fulfill this goal includes the melanin in the solid polymer electrolyte.

Dynamics of change in impedance spectra and electrochemical parameters of the Li-S rechargeable batteries with non-aqueous liquid electrolyte 0.7 M LiIm, 0.25 M LiNO3, DME: DOL (2:1) during storage after assembly and cycling have been shown. For modification of the Sulfur cathode, we used the different types of melanin. Our results confirm that melanin can be used as a promising component of sulfur-based electrodes

“…The electromagnetic non-contact non-destructive testing (3,4) has been used for investigation the conductivities and densities of: 1) powders of carbon materials that included in electrode mass based on sulfur, and 2) powder of cathode mass based on mixture of sulfur and carbon. The porosity and density of the sulfur-based electrode have been also tested.…”
