Devices for testing chemical power sources based on various electrochemical systems

The paper presents a series of universal multifunctional computer-aided devices designed and manufactured at Buster-SPb Ltd. for testing of power sources in various modes. As a rule, testing stands have a module structure with the capability to reprogram charge-discharge modes by the user.

Neva-Reglament (ROSS RU.0001.21SZ27) with enhanced capabilities of testing chemical power sources based on various electrochemical systems for military and civil purposes

The capabilities of a Neva-Reglament testing laboratory designed for evaluation of the compliance of serial and novel power sources with a number of official requirements are shown, including safety requirements, resistance to external exposure, and non-specified attacks.

Experience and problems of small enterprises at the design and production of chemical power sources

The experience of R&D Center AEK Ltd. of the design and production of nickel-cadmium batteries for medium and long discharge (M and L types) at reserve service is presented.

Volume Change When Melting Halides of s'-Elements and their Double Mixes: Analytical Description, Calculation and Interrelation

An important feature when using low-melting mixtures of halides of s-elements as a refiner of electrolytes for chemical power sources and thermal storage materials in thermal batteries is the amount of volume increase in the melting process which can be calculated by the formula [1]:
?V = ((Vк – Vж) / Vк)·100% = (?V/Vк)·100%,(1)

Optimisation of electrode pasting technology

The production of pasted electrodes has been analysed. The equation which connects paste rheology, porous matrix and technologic parameters has been obtained. The approach optimises pasted electrode technology.

Development of material obtained by extraction-pyrolytic technique for electrodes of lithium-ionic cells

Thin film materials LiCoO2, LiCoNixO2, LiCoBixO2, LiCoFexO2 was prepared by extraction-pyralytic technique. Their properties were studied by DTA, electron microscopy, X-ray diffraction, Atomic absorption spectroscopy, IR-spectroscopy an cyclic time-voltage measurements. We established that receiving materials have well electrochemical characteristics. Extraction-pyralytic technique can be recommended as a perspective technique for thin film lithium batteries production.

The analysis of the empirical relationships describing the discharge of alkaline accumulators

It is shown that at small discharging currents for any nickel-cadmium (NC) accumulator the empirical relationship by Khaskina- Danilenko is true and at large discharging currents the relationship by Shepherd is correct. These two relationships don't contradict each other but supplement each other, as they are true for any NC accumulator, each in its interval of discharging currents.

The investigation of the process of heat acceleration in nickel-cadmium accumulators

It has been established experimentally that during the heat acceleration a great amount of hydrogen is given off from nickel-cadmium accumulators.

Effect of sulfur electrode composition on cycling life of Li-S cells

Effect of positive electrodes composition of lithium-sulfur cells on them cycling life was studied. It is shown that the sulfur content in electrodes does not essential influence on the charge-discharge performance, decrease of capacity during cycling life and cycling efficiency of sulfur electrodes, but strongly influences on the internal resistance of lithium- sulfur cells.
