Paunenge uchichaja kutanga, iyo voltage ichachajwa inofanirwa kuongororwa. Mushure mekunge voltage yakwira kusvika ku3V, pinda iyo yakajairwa yekuchaja maitiro. Iyo yakajairwa yekuchaja maitiro ndeiyi: Kana yazvino inomira inogara ichichaja, iyo lithium ion bhatiri voltage inokwira kusvika ku4.

20V, chinja kune kugara uchimanikidza kuchaja, simbirira pamhepo yekuchaja ye4.20V. Panguva ino, iyo yekuchaja inoderera zvishoma nezvishoma, kana ikozvino inodonha kusvika 1/10 yekuchaja ikozvino, kuchaja kunopedzwa.

Kazhinji, iyo lithium bhatiri yekuchaja ikozvino inoiswa pakati pe 0.2c kusvika 1c, iyo yakakura ikozvino, iyo inokurumidza kuchaja, iyo yakakura kupisa kwebhatiri chizvarwa. Uye, yakawandisa ikozvino kuchaja, huwandu hauna kuzara, nekuda kwe electrochemical reaction zvinodiwa zvebhatiri.

Ini ndichatevera doro, uye furo richaonekwa mumashoko. 1. Iyo yekuburitsa ikozvino haigone kuve yakakurisa.

Mvura yakawandisa inokonzera kupisa mukati me lithium-ion bhatiri, iyo inogona kuita dendere kukuvara kwepabonde; 2, haigoni kuwedzera-kubvisa, iyo lithium-ion bhatiri inonyanya kutya kubuda-kudarika, kana simba rekubuda riri pasi pe2.7V, Zvingave zvichibvira kuunganidza bhatiri; 3, kudzivirira kakawanda kudzika kubhadharisa uye kubudiswa: lithium-ion bhatiri haina chiyeuchidzo, vanhu vazhinji vari kushandisa lithium telecoms kana lithium-electric digital products, vanoda kushandisa simba rekutora zvishoma zvishoma pane zvakasara (kuchengetedza bhodhi rekuchengetedza) uye ipapo Kuchaja, mumaziso evanhu vakawanda, iyi inzirawo yekuisa bhatiri; Internal short circuit mubhatiri, nokudaro kuparadza lithium ions, kukonzera kuchengetedzwa kwedunhu; 5. Kana nguva yakareba ichiiswa munzvimbo yakanyanyisa, ichaderedza zvakanyanya hupenyu hwebhatiri.

Kuoma kunowedzera nekumanikidzwa kwemukati, kunyange kana pasina kuputika, bhatiri ichakurumidza kuvharwa mukupisa kukuru. Kudzingirira uye kubudiswa kwemabhatiri e-lithium ion: kubhadharisa mabhatiri e-lithium ion: maererano nemaitiro emagetsi e-lithium magetsi, iyo yepamusoro-soro yekumisa voltage inofanira kuva 4.2V, haigoni kubhadharwa, kana zvisina kudaro, inotora yakawandisa lithium ion mu electrode yakanaka, asi ita bhatiri.

Kuchajisa kwayo uye kubuda kwayo kwakakwira seyakakosha inogara iripo, uye iyo inogara ichivharika charger inovhiringwa. Kazhinji, kugara uchichaja kusvika ku4.2V / mutambo, kuendesa kune inogara ichichaja voltage, apo iyo inogara ichichaja yemagetsi inoderedzwa kusvika 100mA,.

Kuchaja ikozvino (mA) = 0.1 ~ 1.5 nguva bhatiri huwandu (senge 1350mAh bhatiri, yayo yekuchaja ikozvino inogona kudzorwa pakati pe135 kusvika 2025mA).

Yakajairika kuchaja ikozvino inogona kusarudzwa pachiyero che 0.5 times bhatiri huwandu, uye kuchaja kunenge maawa maviri kusvika matatu. Kubuda kwe lithium ion bhatiri: Nekuda kwechimiro chemukati che lithium-ion bhatiri, iyo lithium ion haigone kutamirwa kune yakanaka electrode panguva yekubuda, uye inofanirwa kuchengetedza yemuno lithium ion muiyo negative electrode kuti ive nechokwadi chekuti lithium ion inogona kuiswa mugero kana ichichaja ichitevera.

Zvikasadaro, hupenyu hwebhatiri hunopfupikiswa. Kuti uone kuti ion lithium yemunharaunda yasara mushure mekubuda mu graphite layer, zvakakosha kudzikamisa zvakanyanya yakaderera voltage yekubuda, kureva, lithium ion bhatiri haigone kuburitswa. Iyo discharge stop voltage inowanzoita 3.

0V / chikamu, zvishoma hazvigone kuve zvisingasviki 2.5V / chikamu. Battery discharge nguva inoenderana ne lithium ion bhatiri huwandu, kuburitsa saizi yazvino.

Battery discharge time (awa) = bhatiri simba / discharge ikozvino. Lithium-ion battery discharge current (mA) haifanire kudarika 3 times the battery capacity. (Senge bhatiri re1000mAh, iyo yekuburitsa ikozvino inofanirwa kudzorwa zvakanyanya mukati me3A), zvikasadaro ichakuvadza bhatiri.

Nzira yekubvisa sei lithium-ion bhatiri? Lithium-ion bhatiri yakaenzana mukushanda, mune dzidziso, iyo lithium-ion bhatiri kubuda kunofanirwa kunge kuri kutarisisa chiyero chekubuda uye kudzika kwekubuda. Kudzika kudzika ndiyo chiyero chehuwandu hwekubuda uye huwandu hwezita, iyo yakanakisa referensi index inoshanda ndeye voltage. Iyo yakajairika chiyero ndechekuti lithium-ion bhatiri inoburitswa pakati pe2.

75V uye 3V, inogona kuchajwa kubhatiri. Sezvo iri pasi pe 2.75V, inowanzoitika kune rechargeable bhatiri taboo, uye kana iri mukati mechimiro chemukati, Iri kuwedzeredza volatilization ye electrolyte.

Chechipiri ndechekuti kuita kwakashata kweiyo lithium ion bhatiri kunoita kuti dielectric firimu richinje rinoita kuderera kwegwenga, uye rinoumba kugona kwekurasikirwa nekusingaperi.
