Maererano nenhamba, kudiwa kwepasi rose kwemabhatiri e-lithium-ion kwasvika mabhiriyoni 1.3, uye nekuenderera mberi kwekuwedzera kwenzvimbo dzekushandisa, nhamba iyi iri kuwedzera gore negore.Nekuda kweizvi, nekukurumidza kukurumidza kwekushandiswa kwemabhatiri e-lithium-ion mumaindasitiri akasiyana-siyana, kuchengetedzwa kwebhatiri kuri kuwedzera kukurumbira, zvisingadi kungochaja kwakanakisa uye kuburitsa mashandiro emabhatiri e-lithium-ion, asi zvinodawo mwero wepamusoro. yekuchengetedzwa kwekuita.Iyo lithiamu mabhatiri pakupedzisira nei moto uye kunyange kuputika, ndeapi matanho anogona kudziviswa uye kubviswa?
Chokutanga pane zvose, ngatinzwisise kuumbwa kwezvinhu zve lithiamu mabhatiri.Kushanda kwemabhatiri e-lithium-ion kunonyanya kuenderana nekugadzirisa uye kushanda kwezvinhu zvemukati zvemabhatiri anoshandiswa.Izvi zvemukati zvebhatiri zvinhu zvinosanganisira negative electrode material, electrolyte, diaphragm uye positive electrode material.Pakati pavo, kusarudzwa uye kunaka kwezvinhu zvakanaka uye zvisina kunaka zvinogadzirisa zvakananga kushanda uye mutengo we lithiamu-ion mabhatiri.Naizvozvo, tsvakiridzo yezvakachipa uye yakakwirira kuita yakanaka uye isina kunaka electrode zvinhu kwave kutarisisa kwekuvandudza kwelithium-ion bhatiri indasitiri.
Iyo yakaipa electrode zvinhu zvinowanzo sarudzwa senge kabhoni zvinhu, uye kusimudzira kwacho kwakakura pari zvino.Kuvandudzwa kwezvinhu zvecathode kwave chinhu chakakosha chinodzikamisa kumwe kuvandudzwa kwe lithium-ion bhatiri kuita uye kuderedzwa kwemutengo.Mukugadzirwa kwemazuva ano kwekutengesa kwemabhatiri e-lithium-ion, mari ye cathode zvinhu inokwana 40% yemutengo webhatiri rose, uye kuderedzwa kwemutengo we cathode zvinhu zvinotarisa kuderedzwa kwemutengo we lithiamu-ion mabhatiri.Izvi ndezvechokwadi kunyanya kune lithium-ion simba mabhatiri.Semuyenzaniso, diki lithium-ion bhatiri mbozha runhare inoda chete anenge 5 magiramu cathode zvinhu, nepo lithium-ion simba bhatiri pakutyaira bhazi angada kusvika 500 makirogiramu cathode zvinhu.
Kunyange zvazvo kune theoretically akawanda marudzi ezvigadzirwa zvinogona kushandiswa seyakanaka electrode yeLi-ion mabhatiri, chikamu chikuru chezvakajairwa zvakanaka electrode zvinhu LiCoO2.Paunenge uchichaja, simba remagetsi rinowedzerwa pamatanda maviri ebhatiri rinomanikidza musanganiswa weiyo yakanaka electrode kuburitsa lithium ions, iyo yakaiswa mucarbon yeiyo negative electrode ine lamellar chimiro.Kana yaburitswa, iyo lithium ions inodonha kubva muchimiro chelamellar yekabhoni uye inosanganiswa nekomboni pane iyo yakanaka electrode.Kufamba kwe lithium ions kunogadzira magetsi.Uyu ndiwo musimboti wekuti lithium mabhatiri anoshanda sei.
Kunyangwe iyo musimboti iri nyore, mukugadzirwa chaiko kwemaindasitiri, kune zvimwe zvakawanda zvinoshanda zvekufunga nezvazvo: zvinhu zveiyo yakanaka electrode inoda zvekuwedzera kuchengetedza chiitiko chekuchaja kwakawanda uye kuburitsa, uye zvinhu zveiyo negative electrode inoda kugadzirwa pa iyo molecular structure level kuti igare yakawanda lithium ions;iyo electrolyte yakazadzwa pakati pezvakanaka uye zvisina kunaka electrode, kunze kwekuchengetedza kugadzikana, inodawo kuva nemagetsi akanaka uye kuderedza kupikisa kwemukati kwebheteri.
Kunyangwe iyo lithium-ion bhatiri ine zvese zvakataurwa pamusoro apa zvakanakira, asi zvinodiwa zvedunhu redziviriro zvakanyanyisa, mukushandiswa kweiyo nzira inofanirwa kuve yakanyatso kunzvenga-kuchaja, pamusoro-kuburitsa chiitiko, iyo yekuburitsa ikozvino haifanirwe. ive yakakura kwazvo, kazhinji, chiyero chekubuda hachifaniri kunge chiri chikuru kupfuura 0.2 C. Nzira yekubhadhara ye lithiamu mabhatiri inoratidzwa mumufananidzo.Mukutenderera kutenderera, mabhatiri e-lithium-ion anoda kuona voltage uye tembiricha yebhatiri isati yachaja yatanga kuona kana inogona kuchajwa.Kana magetsi ebhatiri kana tembiricha iri kunze kwechiyero chinotenderwa nemugadziri, kuchaja kunorambidzwa.Iyo inobvumidzwa yekuchaja voltage renji ndeye: 2.5V ~ 4.2V pabhatiri.
Kana bhatiri riri mukubuda kwakadzika, charger inofanirwa kuve ne pre-charge process kuitira kuti bhatiri isangane nemamiriro ekukurumidza kuchaja;zvino, maererano nekukurumidza kuchaja mwero unokurudzirwa nemugadziri webhatiri, kazhinji 1C, charger inochaja bhatiri nemazuva ese uye simba rebhatiri rinokwira zvishoma nezvishoma;kamwe chete bhatiri mhepo inosvika payakagadziriswa yekumisa voltage (kazhinji 4.1V kana 4.2V), iyo inogara ichichaja ikozvino inogumiswa uye yekuchaja ikozvino Kamwe bhatiri vheji rasvika payakagadziriswa termination voltage (kazhinji 4.1V kana 4.2V), iyo inogara ichichaja inogumisa, iyo yekuchaja ikozvino inoora nekukurumidza uye kubhadharisa kunopinda kuzere kuchaja maitiro;panguva yekuchaja kwakazara, iyo yekuchaja ikozvino inoora zvishoma nezvishoma kusvika iyo yekuchaja yadzikira kusvika pazasi C / 10 kana yakazara yekuchaja nguva yadarika, zvino inoshanduka kuita yekuchaja kwepamusoro-chekuchaja;panguva yekuchaja kwepamusoro, charger inozadza bhatiri nechaji chidiki kwazvo.Mushure menguva yekumusoro cutoff kuchaja, kubhadharisa kunodzimwa.
