Lithium battery ke mofuta oa betri e sebelisang lithium tšepe kapa lithium alloy e le lisebelisoa tse mpe tsa electrode 'me e sebelisa tharollo ea electrolyte e se nang metsi.Matla a eona a khethehileng a phahame haholo, empa a na le likotsi tse ka bang teng tsa polokeho.Lintho tse ntle tsa electrode tsa betri ea lithium ke manganese dioxide kapa thionyl chloride, 'me thepa e mpe ea electrode ke lithium.Ka mor'a hore betri e kopane, betri e na le motlakase 'me ha e hloke ho tjhajoa.Mofuta ona oa betri o ka tjhaja, empa ts'ebetso ea potoloho ha e ntle.Nakong ea potoloho ea ho tjhaja le ho tjhaja, ho bonolo ho etsa lithium dendrites, ho fella ka potoloho e khuts'oane ea ka hare ea betri, kahoo ka kakaretso mofuta ona oa betri o thibetsoe ho qosoa.
Betri ea lithium Ion
Lithium Ion Battery (Lion) e bua ka betri e ka nchafatsoang hape e sebelisang li-ion tsa lithium joalo ka lisebelisoa tse sebetsang.Ha betri e tsoa ho motlakase oa ho emisa, e ka tjhajoa hape ho khutlisetsa boemo pele e tsoa.Libetri tsa lithium-ion li boloka le ho lokolla li-ion tsa lithium ka lisebelisoa tse sebetsang tse koahetsoeng holim'a li-electrode, ke hore, ho boloka matla a motlakase ka ho arohana ha li-ion tsa lithium ho lisebelisoa tse sebetsang tsa electrode.Ntho ea bohlokoa ea libeteri tsa lithium ion ha e le hantle ke ho sebelisa phapang ea lithium ion bakeng sa polokelo ea matla le ho e ntša.Ha ho na lithium ea tšepe ka har'a betri, kahoo polokeho ea eona e molemo ho feta ea libeteri tsa lithium, 'me matla a khethehileng a li-betri tsa lithium ion a tlase ho feta a lithium.matla.
3 Phapang pakeng tsa betri ea lithium le betri ea lithium ion
Ka khopolo, libeteri tsa lithium le libeteri tsa lithium-ion ke likhopolo tse fapaneng.Betri e sebelisang tšepe ea lithium e le lisebelisoa tsa electrode e bitsoa lithium battery, e leng ea betri ea mantlha.E ka lahloa ka mor'a ho sebelisoa 'me e ke ke ea sebelisoa hape.Lintho tse ntle tsa electrode tsa betri ea lithium ion ke lithium cobalt oxide (kapa tse ling tsa lithium metal oxide), 'me thepa e mpe ea electrode ke thepa ea carbon.E le ho e khetholla ho betri ea setso ea lithium, e bitsoa lithium ion battery.Libetri tsa Lithium-ion ke libeteri tsa bobeli tse ka nchafatsoang le ho sebelisoa hape, ke hore, libeteri tsa rona tse tloaelehileng tse tjhajoang hape.Bophelong ba letsatsi le letsatsi, batho ba bangata ba ferekanya tse peli mme ba bitsa libeteri tsa lithium-ion tse khutsufalitsoeng joalo ka libeteri tsa lithium, tse lebisang pherekanong ea mehopolo.
Ho boetse ho na le phapang e kholo haholo lipakeng tsa libeteri tsa lithium le libeteri tsa lithium ion electrochemically, ke hore, matla a ho ntša motlakase.Hangata, sethala sa ho ntša betri ea lithium ke 3.0 V, kahoo motlakase oa motlakase oa lithium betri ea lik'hamera tse ngata ke 3.0 V, 'me betri ea lithium ea selefouno e boetse e le 3.0 V. Sethala se tloaelehileng sa ho ntša lithium-ion. Libetri li pakeng tsa 3.6 le 3.8 V. Hona joale, boholo ba liselefouno tsa lithium-ion li na le motlakase oa 3.7 V, 'me tse ling li se li ntse li le 3.8 V. Lebelo lena la motlakase le ka boela la sebelisoa ho khetholla libeteri tsa lithium-ion ho tloha lithium. dibetri.Bophelong, ha ho thata ho bitsa libeteri tse sebelisoang lik'hamera, lilaptop le liselefouno e le libeteri tsa lithium tse nchafalitsoeng kapa libeteri tsa lithium.E bitsoa libeteri tsa lithium ion 'me e khutsufatsoe e le Li-ion kapa Li+.Kgutsufatso ya betri ya lithium ke Li, ntle le + (letshwao le letle la ion).
