Estimation of kinetic activity of the NiOOH/Ni(OH)2 solid-state couple

The results of protons diffusion mathematical modeling in the crystalline lattice of NiOOH/ Ni(OH)2 are caparisoned with data of experiments on thin (100 μm) porous electrodes. The criterion of nickel hydroxide activity is offered as product of proton diffusion coefficient in the crystalline lattice of NiOOH on the square of specific surface area. It was founded existence of protons migration mechanism in a crystalline lattice under action electric field.

Mathematical model of the electrochemical battery with physical constraints of available capacity

The article presents a universal combined model of the electrochemical battery, built on the basis of the modified Shepherd equation and the kinetic model. The proposed model provides the adequate mapping of the basic characteristics of the battery in operating mode, taking into account the physical constraints of the capacity available. The results of verification of the developed mathematical model using lead-acid and lithium-iron-phosphate batteries are presented.


В статье представлена универсальная комбинированная модель аккумуляторной батареи, построенная на основе модифицированного уравнения Шеферда и кинетической модели. Предложенная модель обеспечивает адекватное отображение основных характеристик аккумуляторной батареи в эксплуатационных режимах с учетом физических ограничений на доступную мощность.

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.

Automation of Data Processing of Electrochemical Studies of Battery Cells

The paper considers the problem of increasing the information content of studies of electrochemical battery cells due to in-depth processing of the obtained experimental data. The necessity of developing software with a wider functionality compared to the standard software of battery testers and allowing the processing of experimental data obtained from different types of battery testers in a single interface is substantiated.
