Tehnika areng on suurendanud elektrienergia salvestamist vajavate seadmete kasutamise
võimalusi, mistõttu selle kasutamine on muutunud järjest olulisemaks. Üheks
elektrienergia salvestamise võimaluseks on ülikondensaatorid. Antud bakalaureusetöö
eesmärk on analüüsida ülikondensaatorite kasutusvõimalusi ning tuua välja erinevaid
lahendusi.
Ülikondensaatoreid jagatakse kahte kategooriasse: elektrilised kahekihilised
kondensaatorid ja pseudokondensaatorid. Elektrilised kahekihilised kondensaatorid
salvestavad ioonide adsorptsiooni kaudu elektroodimaterjali pinnale laengu ning
pseudokondensaatorid salvestavad laengut kiirete redoksreaktsioonide kaudu.
Ülikondensaatori tähtsaim omadus on mahtuvus, mida mõõdetakse faradites.
Elektriskeemides kasutatakse ülikondensaatoreid nii akuga koos kui ilma. Akuga
elektriskeemis on ülikondensaator aku abistaja, mis parandab aku eluiga. Tulevikus on
võimalik tekitada aku-superkondesaator seade, millel on nii suur energia- ja
võimsustihedus kui ka pikk eluiga.
With the development of technology, more and more devices are needed that require electricity storage, which is why electricity storage is important in today’s society. One way to store electricity is with supercapacitors. The aim of this bachelor’s thesis is to analyze the possibilities of using supercapacitors and to point out different solutions. Supercapacitors are divided into two categories: electric double-layer capacitors and pseudocapacitors. Electric double-layer capacitors store ions by adsorption on the surface of the electrode material, and pseudocapacitors store charges through rapid redox reactions. The most important feature of the supercapacitor is the capacitance, which is measured in farads. Different technology companies produce capacitors with different capacities. The wiring diagram uses supercapacitor both with and without a battery. In a wiring diagram with battery, a capacitor is a battery assistant that improves battery life. In the future, it will be possible to create a battery-supercapacitor device with a high energy and a high power density as well as a long service life.
