Searohanyi ke karolo ea bohlokoa ea libeteri tsa lithium-ion. Ke lera la microporous le sebelisetsoang ho arola li-electrode tse ntle le tse mpe, 'me ke ntho e sebetsang ea polymer e nang le sebopeho sa nanoscale microporous, joalokaha ho bontšitsoe setšoantšong sa 7{4}}9. Ts'ebetso ea karohano e etsa qeto ea sebopeho sa sebopeho sa betri, khanyetso ea kahare, le litšobotsi tse ling, tse amang ka kotloloho bokhoni ba eona, bophelo ba potoloho le polokeho. Karohano e phahameng-e bapala karolo ea bohlokoa ho ntlafatseng tšebetso eohle ea betri. Mosebetsi oa eona o ka sehloohong ke ho thibela lipotoloho tse khutšoane tse bakoang ke ho kopana le electrode ha li ntse li lumella li-ion tsa electrolyte hore li fete. Bakeng sa libeteri tsa li-ion tsa lithium{9}, kaha electrolyte ke sistimi ea mokelikeli oa lintho tse phelang, ho hlokahala lisebelisoa tsa karohano tse hananang le lihlapolli tsa tlhaho. Ka kakaretso, ho sebelisoa li-membrane tsa porous{10} tse phahameng, tse tšesaane tsa polyolefin.
Ts'ebetso ea searohanyi sa betri ea lithium-ion e etsa qeto ea sebopeho sa sebopeho sa betri le khanyetso ea kahare, e amang bokhoni ba eona ka kotloloho, bophelo ba potoloho le polokeho. Litlhoko tsa tekheniki bakeng sa ho arola betri ea lithium{2}}ion ke:
1) Ts'ebetso ea insulation: Karohano ke sesebelisoa sa motlakase se tsamaisang motlakase, se netefatsang ho itšehla thajana ha mochini pakeng tsa li-electrode tse ntle le tse mpe.
2) Ionic conductivity e phahameng: E tlameha ho fokotsa ho hanyetsa motsamao oa li-ion tsa electrolyte, ho ba le boholo bo itseng ba pore le porosity ho netefatsa hore ho na le khanyetso e tlase le conductivity e phahameng ea ionic, e leng ho lumellang hore lithium{1}}e khone ho kenella hantle.
3) Ho tsitsa ha lik'hemik'hale le ho se sebetse ha electrochemical: E tlameha ho tsitsa ka ho lekaneng khahlanong le electrolyte, litšila tse ka 'nang tsa e-ba teng, li-electrode reactants, le lihlahisoa tsa electrode reaction, ho thibela ho qhibiliha kapa ho senyeha. Kaha motsoako oa electrolyte ke motsoako o matla oa polar organic, karohano e tlameha ho hanana le ho bola ha electrolyte mme e be le botsitso bo lekaneng ba lik'hemik'hale le electrochemical.
4) Ho fokotseha ho fokolang ho tloha ho electrolyte: E tlameha ho ba le metsi a matle ho electrolyte le ho monya metsi a lekaneng le matla a ho boloka mongobo.
5) Matla a phahameng a mochini a hlokahala ho thibela ho taboha le ho senyeha nakong ea ts'ebetso. Thepa e lekaneng ea mochini, ho kenyelletsa matla a ho phunya le matla a ho tsitsa, a bohlokoa, ha a ntse a fokotsa botenya.
6) Botsitso bo boholo bo bohlokoa. Minimal dimensional phetoho e ka tlase ho ntlha ea ho qhibiliha hoa hlokahala ho thibela lipotoloho tse khutšoanyane pakeng tsa li-electrode tse ntle le tse mpe. Botsitso bo botle ba sebaka le ho batalla, hammoho le ho tšoana ho phahameng ka botenya le boholo ba pore, le tsona ke tsa bohlokoa.
7) Botsitso bo botle ba mocheso le ts'ireletso e ikemetseng ea ho koala li bohlokoa. Libetri tsa motlakase li beha litlhoko tse phahameng le ho feta holim'a karohano, hangata li sebelisa li-membrane tse kopaneng.
8) Ho fokotseha ho fokolang ha mocheso hoa hlokahala ho thibela ka katleho ho falla ha likaroloana, li-colloid, kapa lintho tse ling tse qhibilihang pakeng tsa li-electrode tse ntle le tse mpe. Ho seng joalo, lipotoloho tse khutšoane li ka etsahala, tse lebisang ho baleheng ha mocheso oa betri.
Litsamaiso tse fapaneng tsa libeteri tsa lithium{0}ion le lits'ebetso li na le litlhoko tse fapaneng bakeng sa ba arohaneng.
