Phapano ke efe lipakeng tsa libeteri tsa lithium-ion tsa polymer le libeteri tsa lithium-ion?

1.Raw thepa

Battery ea polymer e bolela tšebeliso ea lisebelisoa tsa polymer bonyane ho e ‘ngoe ea likarolo tse tharo tse kholo: electrode e ntle, electrode e mpe kapa electrolyte. Polymer e bolela boima ba limolek’hule tse kholo, ‘me khopolo ea eona e lumellanang ke limolek’hule tse nyenyane, polymer e na le matla a phahameng, boima bo phahameng le elasticity e phahameng. Lisebelisoa tsa cathode tsa betri ea polymer ho phaella ho sebelisoa ha metsoako ea inorganic bakeng sa libeteri tsa lithium-ion, empa hape le polymer conductive; li-electrolyte tsa betri ea polymer ke li-electrolyte tsa polymer (li-solid kapa gel state) le organic electrolyte, libeteri tsa lithium-ion li sebelisa electrolyte.

2.Shaping diphapano

Libetri tsa lithium-ion tsa polymer li ka ba tšesaane, sebaka leha e le sefe le sebopeho leha e le sefe, lebaka ke hore electrolyte ea eona e ka ba e tiileng kapa boemo ba gel ho e-na le ho ba metsi, ha libeteri tsa lithium-ion li sebelisa electrolyte, ho khetla e matla e le sephutheloana sa bobeli ho amohela electrolyte. . Ka hona, sena se boetse se etsa hore betri ea lithium-ion e eketsoe karolo ea boima.

3.Polokeho

The polymer hona joale boholo ba bonolo pakete betri, ho sebelisa aluminium-polasetiki filimi e le khetla, ha ka hare organic electrolyte, esita le haeba mokelikeli ke chesa haholo, ha e phatloha, hobane aluminium-polasetiki filimi polymer betri e sebelisa boemo bo tiileng kapa gel. ntle le ho dutla, ho phatloha ha tlhaho feela. Empa ntho e ‘ngoe le e’ ngoe ha e phethehe, haeba nako ea nakoana e phahame ka ho lekaneng, potoloho e khutšoanyane, ho tuka ha betri ka tšohanyetso kapa ho phatloha ha ho khonehe, liselefouno le likotsi tsa ts’ireletso ea PC li bakoa ke boemo bona. ‘Me libeteri tsa lithium iron phosphate e bile liteko tse matla tsa polokeho, leha ho ka thulana le likhohlano tse matla li ke ke tsa phatloha.

4.cell voltage

Joalokaha libeteri tsa polymer li sebelisa lisebelisoa tsa polymer, li ka etsoa ka seleng ea li-multi-layer motsoako ho finyella matla a phahameng, ‘me lisele tsa lithium-ion betri ea matla ke 3.6V, ho finyella matla a phahameng ka ho sebetsa, hoa hlokahala ho hokahanya lisele tse ngata ka letoto. ho theha sethala se loketseng sa motlakase o phahameng.

5.Boitšoaro

The ionic conductivity ea elektrolyte e tiileng ea betri ea lithium-ion polymer e tlase. Hajoale, li-additives tse ling li eketsoa haholo ho e etsa gel electrolyte ho ntlafatsa conductivity. Sena se boetse se eketsa conductivity e ncha ea ionic, ho fapana le libeteri tsa lithium-ion, tse bolokang boleng bo tsitsitseng ba conductivity ntle le ho angoa ke boleng ba lisebelisoa tse thusang.


libeteri tsa setulo sa likooa tsa motlakase, li-betri tse kenyellelitsoeng, li-monitor voltage ea betri, betri ea mochini oa B-ultrasound, polokelo ea betri ea matla a letsatsi, k’hamphani ea betri ea lithium, leihlo la betri, lisebelisoa tsa matla a betri holim’a baesekele, libeteri bakeng sa mabone a manyane, lekola laptop ea betri.
