Structural and Electrochemical Characteristics of Porous Lead Electrodes with Additive Nanostructured Carbon

The effect of carbon materials of two types was studied: multi-walled carbon nanotubes (“Art-nano” of the NSU “S” brand (TU BU 690654933.001.-2011)) and multilayer graphene (“Art-nano GT” (TU BU 691460594.004–2017), and modifications by treatment with ozone and dimethylformamide (manufacturer LLC Advanced Research and Technology, Belarus) on the structural characteristics, capacity and utilization of the active mass of the negative electrode of a lead-acid battery.

Features of Lead-Acid Battery Modelling

One of the key steps to improve environmental situation is reducing pollutants released by automobiles. As of now, electric cars are the most commonly used type of eco-friendly vehicles. However, having a limited travel range they require an infrastructure system of charging stations to operate. Moreover, while electric vehicles don’t produce negative emissions directly they can still contribute to pollution if their energy is generated using fossil fuels. To further improve environmental benefits of electric cars charging stations on renewable energy sources should be developed.

УДК 541.135


The review deals with studies of the properties of lead alloys used to fabricate electrode grids of sealed lead-acid batteries.

Positive electrode for reserve chemical current source

We studied the electrochemical deposition of lead dioxide on titanium coated with colloidal graphite. It is showing that under optimal process conditions possible to obtain high quality coatings with good adhesion to the base and high-bit characteristics. Received bit characteristics of the layout of the backup power source.

/The effect of modified absorbtive glass mat separators on the efficiency of hydrogen ionization in lead-acid battery mock-ups

The influence of porous structure of the absorptive glass mats manufactured by «Hollingsworth&Vose» (thickness 2.8 mm) and BernardDumas» (thickness 3.0 mm), modified by impregnation with polymeric emulsions on the basis of polyvinylidene fluoride (KYNAR), polyvinylpyrrolidone copolymer with styrene (PVS) and polytetrafluoroethylene (Tf), on the efficiency of ionization of hydrogen in lead-acid battery mock-ups. The use of polymer modified emulsions separators from absorbtive glass mat allows to increase the ionization rate of hydrogen on lead-dioxide electrode.

Measurement of lead-acid battery internalresistance in charging mode

Method and the resultsof measurementof the internalresistance ofbattery duringitschargeanddischarge are described.It was establishedthat the internal resistance ofthe batteryin operatingvoltage range is almost equallywhencharging and dischargingand does not dependon the current.

Estimation of lead-acid batteries exploitation possibility in high-rate charge and partial state of charge mode

Lead-acid batteries exploitation possibility in pfrtial state of charge mode is demonstrated. Influence of this mode on chfracteristics of lead-acid batteries is studied.

Anodic behavior of electrolytically deposited lead and zinc in perchloric acid solutions and their possible use as anodes in backup power sources

The behavior of electrolytically deposited Pb and Zn in 40% perchloric acid at temperatures ranging from 30°C – +55°C. It is established that the electrochemical system Zn/HClO4/PbO2 has a higher discharge voltage and specific capacity compared to the system РЬ/НClO4/РЬO2. It is shown that in the temperature range from 0°C to +55°C the specific capacitance of the investigated electrochemical systems vary slightly.
