Etsa tlhahlobo ea botsofali

Hona joale lihlahisoa tsohle tse ncha tsa mohopolo oa matla a likoloi tse ncha tsa matla le liroboto tse ncha tsa matla li sebelisa matla a macha a betri ea lithium ho etsa libeteri tsa lithium tse nang le matla a maholo. Joale lintlha tsa tekheniki tsa libeteri tsee tsa lithium ke life? Re utloisisa boholo bo sebelisoang hangata ba li-battery tse arohaneng. 18650 ke mothehi oa libeteri tsa lithium. E le ho boloka litšenyehelo, Sony Corporation ea Japane e ile ea hlahisa betri e tloaelehileng ea lithium e bophara ba 18mm, bolelele ba 65mm, le bolelele.

Libetri tse tloaelehileng tsa 18650 li arotsoe ka libeteri tsa lithium le libeteri tsa lithium iron phosphate. Matla a lebitso la betri ea lithium ke 3.7V, motlakase o khaotsoeng oa ho tjhaja ke 4.2V, motlakase oa lebitso la betri ea lithium iron phosphate ke 3.2V, motlakase o khaotsoeng ke 3.6V, matla a kakaretso ke 1200mah- 3000mah, ‘me matla a kakaretso ke 2200Mah-2600mah.

Libetri tsa lithium li utloisisa hore na ke eng ka har’a karohano ea betri, joale botsofali ke eng?

Botsofali ke mokhoa oo sehlahisoa se kenngoa le ho sebelisoa tlas’a mocheso o itseng le / kapa mojaro. Ka mor’a nako kapa potoloho, lipakane tsa ts’ebetso ea sehlahisoa lia finyelloa.

Botsofali ba betri ea lithium hangata bo bolela ente ea mokelikeli ka mor’a hore betri e behoe le ho kopanngoa, e ka ba botsofali bo tloaelehileng ba mocheso kapa botsofali bo phahameng ba mocheso. Sepheo sa eona ke ho tsitsisa ts’ebetso le sebopeho sa filimi ea SEI e entsoeng ka mor’a ho tjhaja qalong. Mocheso oa kamore ea botsofali ke likhato tse 25, ‘me mocheso o phahameng o tsofala limela tse fapaneng, likhato tse ling tsa 38 kapa likhato tse 45, nako e pakeng tsa lihora tse 48 le 72.

Botsofali le insulation li tiisa botsofali:

Mabapi le botsofali bo bulehileng ba betri, mabapi le botsofali ba mocheso oa kamore, haeba mongobo o lekanyelitsoeng o ka laoloa ka tlase ho 2%, ho molemo ho o tiisa ka mor’a botsofali.

Bakeng sa botsofali bo phahameng ba mocheso, ho tiisa botsofali ho molemo.

Empa ho hlakile hore ho na le liphetoho tse matla tsa electrochemical nakong ea botsofali, e leng thuso e kholo ho botsitso ba SEI mme e ka khothalletsa botsitso ba tsamaiso ea electrochemical.

Molao-motheo le morero oa botsofali ba electrolyte ea betri ea lithium ke ho nosetsa ka ho feletseng, ‘me e’ ngoe ke hore likarolo tse ling tse sebetsang tsa thepa ea cathode li tlameha ho etsoa ka karabelo, e le hore betri ka kakaretso e bolokehe, lik’hamphani tse ngata. e le ho etsa hore ts’ebetso e potlake, botsofali bo phahameng ba mocheso , Empa botsofali bo phahameng ba mocheso bo hloka ho ela hloko nako ea taolo le mocheso. Hobane botsofali bo phahameng ba mocheso bo ka hlahisa lintho tse phelang tse fetang mocheso o tloaelehilengDegree botsofali, phello ea taolo ea ho senyeha e ntle, metsoako e sebetsang e bonahatsa ka botlalo litšobotsi tsa ts’ireletso ea betri, taolo ha e ntle, karabelo e fetelletseng, kahoo mosebetsi oa motlakase ke fokotsehile , Matla a fokotsehile, infrared e ncha, ‘me ho na le monyetla oa ho lutla

Kamora ho tsofala ha mocheso o phahameng, ts’ebetso ea betri e tsitsitse haholoanyane. Boholo ba baetsi ba betri ea lithium ba sebelisa ts’ebetso ea botsofali ba mocheso o phahameng nakong ea tlhahiso. Ho tsofala ho 45 ~ 50C bakeng sa matsatsi a 1 ~ 3, ebe ka mocheso oa kamore. Lintho tse ka ‘nang tsa sa lakatsehe li tla pepesoa ka mor’a botsofali bo phahameng ba mocheso oa betri: phetoho ea motlakase, phetoho ea botenya le phetoho ea ho hanyetsa ka hare ke liteko tse tobileng tsa polokeho ea betri le ts’ebetso ea electrochemical.

Botsofali bo phahameng ba mocheso E le ho khutsufatsa potoloho eohle ea tlhahiso ea betri, ke libapali feela tse kenang betereng mme ke betri feela e potlakisang ts’ebetso ea lik’hemik’hale ka mocheso o phahameng. Betri ha e fete melemo e ka senyang betri. Nako e ntle ka ho fetisisa ea ho kenngoa ha mocheso oa kamore ke libeke tse fetang tse tharo, re na le negative E, ha ho leka-lekana pakeng tsa lekhalo le electrolyte ho kopana le lik’hemik’hale tsa lik’hemik’hale, betri ke ‘nete.
