Ita bvunzo yekuchembera

Iye zvino ese matsva emagetsi emagetsi emagetsi emagetsi matsva uye marobhoti emagetsi matsva anoshandisa simba nyowani lithium mabhatiri kuumba yakakura-inokwana mabhatiri e lithium. Saka ndedzipi tekinoroji zvirevo zveaya mabhatiri e lithium? Isu tinonzwisisa masaizi anowanzo shandiswa emabhatiri ekuparadzanisa. 18650 ndiye muvambi we lithium mabhatiri. Kuitira kuchengetedza mari, Sony Corporation yekuJapan yakaunza bhatiri re lithium rine dhayamita 18mm, kureba kwe65mm, uye kureba.

Zvakajairwa 18650 mabhatiri akakamurwa kuita lithium mabhatiri uye lithium iron phosphate mabhatiri. Iro zita remagetsi re lithium bhatiri i3.7V, iyo yekuchaja yakachekwa-kubvisa voltage ndeye 4.2V, iyo inonzi nominal voltage yelithium iron phosphate bhatiri ndeye 3.2V, iyo yekuchaja yekucheka-kubvisa voltage i3.6V, iyo general capacity i1200mah- 3000mah, uye huwandu hwese huri 2200Mah-2600mah.

Lithium mabhatiri anonzwisisa kuti chii chiri mubhatiri separator, saka chii kuchembera?

Kuchembera inzira iyo chigadzirwa chinotakurwa uye kushanda pasi peimwe tembiricha uye/kana mutoro. Mushure menguva yenguva kana kutenderera, zvinangwa zvinoshanda zvechigadzirwa zvinosangana.

Lithium bhatiri kuchembera kunowanzo reva jekiseni remvura mushure mekunge bhatiri ratanga kuiswa uye kuunganidzwa, izvo zvinogona kunge zviri tembiricha kuchembera kana kuchembera kwakanyanya. Chinangwa chayo ndechekudzikamisa kuita uye kuumbwa kweiyo SEI firimu yakaumbwa mushure mekutanga kuchaja. Mukamuri tembiricha kuchembera tembiricha iri 25 madhigirii, uye tembiricha kuchembera zvirimwa zvakasiyana, mamwe 38 madhigirii kana 45 madhigirii, nguva iri pakati 48 uye 72 maawa.

Kuchembera uye kuisa chisimbiso kuchembera:

Nezve kuchembera kwakavhurika kwebhatiri, maererano nekuchembera kwekamuri yekuchembera, kana hunyoro hwehukama hunogona kudzorwa pasi pe2%, zviri nani kuisimbisa mushure mekuchembera.

Kuchembera kwekushisa kwepamusoro, kuvhara kuchembera kwekuita kuri nani.

Asi ndezvechokwadi kuti kune electrochemical dynamic shanduko panguva yekukwegura, iyo inobatsira zvikuru kugadzikana kweSEI uye inogona kukurudzira kugadzikana kwe electrochemical system.

Nheyo uye chinangwa chekuchembera kwe electrolyte ye lithium bhatiri ndeyekunyorovesa zvakakwana, uye imwe yacho ndeyekuti zvimwe zvinoshanda zvecathode zvinhu zvinofanirwa kuvharwa nemhinduro, kuitira kuti bhatiri sebasa rese rive rakachengeteka, makambani mazhinji. kuitira kuti hurongwa huve nekukurumidza, kuchembera kwakanyanya, Asi kuchembera kwakanyanya kunoda kutarisisa nguva yekudzora uye tembiricha. Nekuti tembiricha yakanyanya kuchembera inogona kuburitsa zvinhu zvipenyu zvinodarika tembiricha yakajairwaDegree kuchembera, iyo degradation control mhedzisiro yakanaka, izvo zvinoshanda zvinongedzo zvinoratidzira hunhu hwekuchengetedza bhatiri, kutonga hakuna kunaka, maitiro akawandisa, saka basa remagetsi riripo. yakaderedzwa , Kuwanda kwakaderedzwa, iyo infrared inyowani, uye pane kunyange mukana wekudonha

Mushure mekuchembera kwekushisa kwepamusoro, basa rebhatiri rinonyanya kugadzikana. Vazhinji vagadziri ve lithium bhatiri vanoshandisa tembiricha yekuchembera mashandiro mukugadzira. Kuchembera pa45 ~ 50C kwemazuva 1 ~ 3, uyezve pane tembiricha. Zvingangoitika zvisingadiwe zvichaburitswa mushure mekuchembera kwakanyanya kwebhatiri: shanduko yemagetsi, shanduko yehukobvu uye shanduko yemukati yekuramba ndeye bvunzo dzakananga dzekuchengetedza bhatiri uye kuita kwe electrochemical.

Kuchembera kwekushisa kwepamusoro Kuti upfupise kutenderera kwese kwebhatiri, vatambi chete ndivo vanopinda mubhatiri uye chete bhatiri rinomhanyisa kuita kwemakemikari pakupisa kwakanyanya. Bhatiri harina kudarika mabhenefiti anogona kukanganisa bhatiri. Iyo yakanakisa tembiricha yekamuri yekuisa nguva inopfuura mavhiki matatu, isu tiri negative Hongu, kana chiyero chiri pakati pegap ne electrolyte chinosangana nemakemikari reaction, bhatiri ichokwadi.
