Твърди електролити

тел: (+359 2) 979 2767, ел. поща: tpetkova@iees.bas.bg

Научно-изследователска област

Научните интереси на членовете от секция „Твърди електролити“ са свързани с разработване на песрпективни материали за приложение в електрохимията. Секцията притежава дългогодишен опит в синтеза и охарактеризирането на неорганични материали (халкогенидни и оксидни) и на хибридни материали, получени като масивни, тънки слоеве или нанокомпозитни материали. Използват се традиционни (синтез от стопилка и вакуумно-термично отлагане) и съвременни (зол-гел, хидротермален) методи за получаването им. Работи се по създаване на композитни електролитни материали за литиеви батерии. Изследват се електроди, имобилизирани с фоточувствителни молекули за очистване на води, както и на неорганични и хибридни материали, получени във вид на тънък слой за приложение като оптични сензори и биосензори. Получават се и се изследват нанокристални диамантени слоеве за фотоелектрохимично приложение. Разработват се нови материали за приложение като електролити в нискотемпературни горивни клетки.
