Ikhono lento yokudlulisa amandla kagesi libizwa ngokuthi ukuqhutshwa. Izinsimbi ezihlukene zinemigubho ehlukene, ngokuvamile isiliva ine-conductivity engcono kakhulu, ilandelwa ithusi negolide. I-Solid-state conduction ibhekisela ekufudukeni kwebanga elide kwama-electron noma ama-ion endaweni eqinile ngaphansi kwesenzo senkundla kagesi, ngokuvamile isithwali sokushaja, njengalokhu: i-electron conductor, eqhuba ugesi ikakhulukazi ngabathwali be-electron; Conductivity of the host; nama-conductor axubile, anakho kokubili ama-electron enkampani yenethiwekhi nama-ion. Ngaphezu kwalokho, ezinye izenzakalo zikagesi azibangelwa ukufuduka kwenkampani yenethiwekhi, kodwa i-polarization eqinile ebangelwa inkambu kagesi, njenge-dielectric phenomena kanye nezinto ze-dielectric.
Ngokuvamile, izinsimbi, ama-semiconductors, ama-electrolyte, ama-electrolyte ancibilika futhi amanye angewona ama-metal angaqhuba ugesi. I-conductivity kagesi yezinto ezingezona i-electrolyte incike enanini lama-electron amahhala egobolondweni layo langaphandle le-athomu kanye nesakhiwo sayo sekristalu. Isibonelo, izinsimbi ziqukethe inani elikhulu lama-electron amahhala, futhi eziningi ezingezona izinsimbi akulula ukuqhuba ugesi ngenxa yenani lazo elincane kakhulu lama-electron amahhala. Idayimane ine-conductivity kagesi, ehlobene nomehluko wesakhiwo sayo se-crystal. Ama-electrolyte aqhuba ugesi ngoba ama-anion akhiwa lapho ama-ionic compounds encibilika noma encibilika, futhi ngaleyo ndlela aqhube ugesi.
Njengensimbi ye-conductive ngaphandle kwesiliva, ithusi ngokuvamile lisetshenziselwa izintambo ezibalulekile namapuleti e-conductive. Ukuphakama kokuhlanzeka, ngcono i-conductivity.
Njengempahla yesakhiwo esinezimbobo ze-3D eyenziwe ngethusi njengempahla eluhlaza, ikhwalithi yegwebu lethusi ingcono futhi iphakame ubuchwepheshe bokukhiqiza, iphakamisa ukuhlanzeka kwethusi, futhi kuba ngcono ukuqhutshwa kukagesi ngokufanele.
I-conductivity kagesi ye-foam yensimbi ihlobene ne-conductivity kagesi yensimbi yobuningi. Ezimweni eziningi, kukhona ama-oxides ane-conductivity engalungile ebusweni bensimbi eyisisekelo, futhi kukhona ama-conductor amaningi amabi kagesi esakhiweni esinezimbotshana zensimbi enegwebu, ngakho-ke ukuqhutshwa kwensimbi enegwebu akukuhle njengalokho. yensimbi ngobuningi.
Ebhalansini ye-conductivity kagesi kanye nesakhiwo se-porous se-3D, kuye kwasungulwa amamodeli amaningana acabangela kokubili. Ekusetshenzisweni, nakuba i-conductivity kagesi ingekho kahle njengaleyo yezintambo zethusi ezihlanzekile eziqinile namashidi, izinzuzo zesakhiwo se-3D se-porous sisetshenziswa ngokugcwele. Uma kuqhathaniswa nezinto zethusi ezihlanzekile ezingaqinile, ukuqhutshwa kukagesi kwegwebu lethusi kungcono.
