Комплексная характеризация положительных электродов свинцово-кислотного аккумулятора с двухсторонним коррозионностойким магнетронным покрытием из титана.</p></sec><sec><title>   Методы</title><p>   Методы. Магнетронное распыление особо чистой мишени из Ti на обе стороны серийных типоразмеров токоотводов положительных электродов 2-вольтовой модельной ячейки свинцово-кислотного аккумулятора (два токоотвода отрицательных и между ними один положительный электрод) осуществлялось при мощности P = 300 Вт в течение t = 10 мин. Характеризация магнетронных пленок проводилась методами рентгенофазового анализа, сканирующей (растровой) электронной микроскопии, энергодисперсионного анализа. Сравнивались коррозионная устойчивость и электрические характеристики 2-вольтовых модельных ячеек с токоотводами положительных электродов с покрытием из Ti и без него.</p></sec><sec><title>   Результаты</title><p>   Результаты. По результатам рентгенофазового анализа в магнетронных титановых покрытиях обнаружено формирование оксидной пленки из диоксида титана, которая не изменяла измеряемые электрические характеристики и играла роль дополнительной химической пассивации. Емкости полностью заряженных 2-вольтовых модельных ячеек, определенные в испытаниях при разряде током 20-часового режима 0,75 А и током холодной прокрутки 50 А при температурах минус 18 ºС и минус 30 ºС, были сопоставимы с серийно выпускаемыми аккумуляторами.</p></sec><sec><title>   Заключение</title><p>   Заключение. Свинцовые токоотводы положительных пластин с магнетронным покрытием титана показали высокую коррозионную стойкость по сравнению с серийно выпускаемыми свинцово-кислотными аккумуляторами после 26-дневного нагрева при 60 °С, в том числе при заряде при постоянном напряжении 2,33 В в течение 13 суток без изменения первоначальных электрических характеристик. После проведенных испытаний модельных ячеек по визуальному сравнению токоотводов положительных электродов с покрытием из Ti и без него отмечено отсутствие разрывов в сегментах решеток и повышенная развитость поверхностей, что свидетельствует о повышении их коррозионной стойкости, что крайне важно при производстве таких аккумуляторов.</p></sec></abstract><trans-abstract xml:lang="en"><p>   Purpose of the research. Comprehensive characterization of lead-acid battery positive electrodes with a double-sided corrosion-resistant Titanium magnetron coating.</p><sec><title>   Methods</title><p>   Methods. Magnetron sputtering of a high-purity Ti target onto both sides of standard-sized positive electrode current leads of a 2-volt model cell of the lead-acid battery (two negative current leads and one positive electrode between them) was performed at a power of P = 300 W for t = 10 min. Magnetron films were characterized using X-ray diffraction analysis, scanning electron microscopy, and energy-dispersive analysis. The corrosion resistance and electrical characteristics of 2-volt model cells with positive electrode current leads coated with and without Ti were compared.</p></sec><sec><title>   Results</title><p>   Results. X-ray diffraction analysis revealed the formation of a titanium dioxide oxide film in the magnetron titanium coatings. This film did not alter the measured electrical characteristics and acted as additional chemical passivation. The capacities of fully charged 2-volt model cells, determined in tests under 20-hour discharge conditions with a 0.75 A current and a 50 A cold cranking current at temperatures of -18ºC and -30ºC, were comparable to those of commercially available batteries.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Lead current leads of positive plates with a titanium magnetron coating demonstrated high corrosion resistance compared to commercially available lead-acid batteries after 26 days of heating at 60°C, including charging at a constant voltage of 2.33 V for 13 days without changing their initial electrical characteristics. Following testing of 2-volt model cells, visual comparison of positive electrode current leads with and without a Ti coating revealed no discontinuities in the grid segments and increased surface development, indicating increased corrosion resistance, which is crucial for the production of such batteries.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>свинцово-кислотный аккумулятор</kwd><kwd>коррозионная стойкость</kwd><kwd>токоотводы</kwd><kwd>положительные электроды</kwd><kwd>магнетронное распыление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lead-acid battery</kwd><kwd>corrosion resistance</kwd><kwd>positive electrode</kwd><kwd>current leads</kwd><kwd>magnetron sputtering</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках государственного задания на 2025 год № 075-03-2025-526</funding-statement><funding-statement xml:lang="en">The article was prepared as part of the state assignment for 2025 No. 075-03-2025-526</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Oxygen-functionalized defect engineering of carbon additives enable lead-carbon batteries with high cycling stability / J.
