Lithium-ion bhatirikuputika kunokonzera:
1. Kukura kwemukati polarization;
2. Chidimbu chinotora mvura uye chinopindirana ne electrolyte gas drum;
3. Hunhu uye kushanda kwe electrolyte pachayo;
4. Kuwanda kwejekiseni remvura hakusviki zvinodiwa nemaitiro;
5. Kusaisa chisimbiso kushanda kwelaser welding mugadziriro yegungano uye kubuda kwemhepo pakuyera kubuda kwemhepo;
6. Dust, pole piece dust iri nyore kutungamirira kune micro-short circuit pakutanga;
7. Positive and negative pole zvidimbu zvakakora kudarika maitiro ekugadzirisa, uye zvakaoma kupinda mugoko;
8. Dambudziko rekuvhara jekiseni remvura, simbi yesimbi yekuisa chisimbiso kuita haina kunaka inotungamira kune gasi dhiramu;
9. Shell inopinda shell wall ukobvu, shell deformation inokanganisa ukobvu;
10. Kunze kwekushisa kwepamusoro ambient zvakare chikonzero chakakosha chekuputika.
Matanho ekudzivirira anotorwa nebhatiri:
Lithium-ion bhatirimaseru akachajirwa kuvoltage yakakwira kupfuura 4.2V uye anozotanga kuratidza maside effects.Kukwira kwevoltage ye overcharge, ndiko kuwedzera kwengozi.Kana simba re lithium cell rakakwirira kudarika 4.2V, isingasviki hafu yeatomu ye lithiamu inoramba iri mumagetsi akanaka e electrode, uye nzvimbo yekuchengetedza inowanzoputsika, zvichiita kuti kudonha kusingagumi kwebheteri.Kana kuchaja kuchienderera mberi, sezvo nzvimbo yekuchengetera ye electrode isina kunaka yakatozara neatomu yelithium, iyo inotevera lithium simbi ichaungana pamusoro peiyo negative electrode zvinhu.Aya maatomu e-lithium anozokura dendritic makristasi kubva kune anode pamusoro akananga kune lithium ion.Aya makristasi e-lithium simbi achapfuura nepakati pediaphragm bepa uye pfupi-circuit iyo yakanaka uye yakaipa electrodes.Dzimwe nguva bhatiri rinoputika kusati kwaitika nguva pfupi, izvi imhaka yekuti mukuwedzera kwekuchajisa, electrolyte nezvimwe zvinhu zvichatsemuka kuti zvionekwe gasi, zvichiita kuti bhatiri ganda kana kumanikidza vharavha kuputika kuputika, kuitira kuti okisijeni ipinde muchiitiko nekuunganidza. ye lithiamu maatomu pamusoro peiyo negative electrode, yobva yaputika.
Naizvozvo, pakuchajalithium-ion mabhatiri, muganho wepamusoro wemagetsi unofanirwa kuiswa kuitira kuti utarise hupenyu, huwandu, uye kuchengetedzeka kwebhatiri panguva imwe chete.Iyo yakakodzera yepamusoro yepamusoro yekuchaja voltage ndeye 4.2 V. Panofanirawo kunge paine yakaderera voltage muganho pakuburitsa lithium masero.Kana sero voltage inowira pasi pe2.4V, zvimwe zvezvinhu zvinotanga kuparadzwa.Uye nekuti bhatiri richazviburitsa rega, kana iwe ukaisa yakaderera voltage ichava, saka, zvakanakisa kusaburitsa ku2.4V usati wamira.Simba rakaburitswa mukati menguva kubva pa3.0V kusvika 2.4V rinongotora chikamu che3% chesimba rebhatiri re lithium-ion.Naizvozvo, 3.0V ndiyo yakanaka yekucheka-off voltage yekuburitsa.Paunenge uchichaja uye uchiburitsa, mukuwedzera kune voltage kudzikisira, ikozvino kudzikiswa kunodiwa zvakare.Kana ikozvino yakanyanyisa, iyo lithium ions haina nguva yekupinda mukamuri yekuchengetedza uye ichaunganidza pamusoro pezvinhu.
Izvilithium ionskuwana maerekitironi uye kupenya maatomu e-lithium pamusoro pezvinhu, izvo zvakafanana nekuchajisa uye zvinogona kuva nengozi.Muchiitiko chekuputika kwebheteri kesi, ichaputika.Naizvozvo, kuchengetedzwa kwemabhatiri e-lithium-ion kunofanirwa kusanganisira zvinhu zvitatu: muganho wepamusoro wekuchaja voltage, muganho wakaderera wekuburitsa voltage, uye muganho wepamusoro wezvino.General lithium-ion battery packs, kuwedzera kune lithium-ion bhatiri masero, pachava neplate yekudzivirira, iyi ndiro yekudzivirira inokosha kupa izvi zvitatu zvekudzivirira.
