Manganese-Doped Titanium Dioxide with Improved Electrochemical Performance for Lithium-Ion Batteries

Within the work, an influence of manganese dopant on electrochemical performance of anatase titanium dioxide (Mn/Ti = 0.05; 0.1; 0.2) had been investigated. It was established that incorporation of Mn3+ into the TiO2 lattice results in the formation of Ti1 − xMnxO2 solid solution and increased anatase unit cell volume from 136.41 Å3 (undoped sample) to 137.25 Å3 (Mn/Ti = 0.05). The conductivity of doped TiO2 rises up to two orders in magnitude.

Elements of electrochemical system lithium-fluorinated carbon for capsular endoscopy and video-capsules of domestic development are developed. Their significant advantages over traditional silver-zinc current sources for these products are shown both in terms of operating time and energy parameters. The discharge characteristics, reliability and trouble-free operation with mock-ups of domestic gastro-capsules are investigated.

Comparison of traditional organic solvents with phosphoric acid esters in lithium-ion and supercapacitor technologies

This work is dedicated to phosphoric acid esters working as solvents for lithium-ion and supercapacitor (SC) electrolyte. The electrical conductivity of electrolytes based on phosphoric acid esters, lithium salts, commonly used in lithium-ion batteries (LIB), and salts used in SC technology was measured. The thermodynamic stability of new electrolytes in comparison with other solvents used in chemical power sources technology was also estimated. It was shown that the thermodynamic stability of phosphoric acid ester increases in a homologous series.

Technological bases of lithium-ion batteries production

It is shown that the performance of lithium-ion battery is significantly affected by the component structure of the electrodes, electrode fabrication technology, forming the battery mode. It is shown that in the production of lithium-ion batteries can be used the following materials: as a binder – polymer dispersion of water-based СНР 500, the negative electrode material – synthetic graphite 131181008–1 brands and 20130905.

Properties of LiFePO4-based cathode material with additions of conducting polymer for Li–ion batteries

In this study, the electrochemical behavior and properties of the novel LiFePO4-based composite cathode material with a water-soluble binder LA-133 and a conductive polymer PEDOT:PSS (poly-3,4-ethylenedioxythiophene: polystyrenesulfonate) as an aqueous dispersion were studied. Using the conductive polymer in combination with a water-soluble binder LA-133 allows to reduce the proportion of electrochemically inactive components (up to 10\%) and thus to increase its specific capacity for a given weight of the active material.
