Kukonzeresa kuongororwa uye mhinduro dzezvakajairwa matambudziko e lithium ion bhatiri

Nekukurumidza kukura kwesainzi uye tekinoroji, chiyero uye basa relithium mabhatirizvagara zvichizviratidza, asi muhupenyu hwedu hwezuva nezuva, njodzi dze lithium bhatiri dzinogara dzichibuda mukusingaperi, izvo zvinogara zvichititambudza.Nekuda kweizvi, mupepeti anonyatso kuronga lithium Kuongorora kwezvakakonzera matambudziko akajairika eiyoni uye mhinduro, ndinovimba kukupa iwe nyore.

1. Mhepo haipindirani, uye dzimwe dzakaderera

1. Kuzvibvisa kukuru kunokonzera low voltage

Kuzviburitsa kwesero kwakakura, zvekuti voltage yaro inodonha nekukurumidza kupfuura mamwe.Iyo yakaderera voltage inogona kubviswa nekutarisa voltage mushure mekuchengetedza.

2. Kusaenzana kuchaja kunokonzera kuderera kwemagetsi

Apo bhatiri rinobhadharwa mushure mekuedzwa, bhatiri sero harina kubhadharwa zvakaenzana nekuda kwekusagadzikana kwekubatana kwekupikisa kana kutengesa ikozvino kwekambani yekuongorora.Musiyano wevoltage wakayerwa idiki panguva yekuchengetera kwenguva pfupi (maawa gumi nemaviri), asi mutsauko wevoltage wakakura panguva yekuchengetedza kwenguva refu.Iyi low voltage haina matambudziko emhando uye inogona kugadziriswa nekuchaja.Kuchengetwa kweanopfuura maawa makumi maviri nemana kuyera voltage mushure mekuchajwa panguva yekugadzira.

Chechipiri, kupikisa kwemukati kwakanyanya

1. Misiyano yekuona michina yakakonzerwa

Kana kurongeka kwekuona kusina kukwana kana boka rekubatana harigone kubviswa, kupikisa kwemukati kwekuratidzira kuchave kwakakura.Iyo AC bhiriji nzira musimboti unofanirwa kushandiswa kuyedza kupikisa kwemukati kwechiridzwa.

2. Nguva yekuchengeta yakarebesa

Lithium mabhatiri anochengeterwa kwenguva yakareba, zvichikonzera kurasikirwa kwesimba rakawandisa, kufambisa kwemukati, uye kupikisa kukuru kwemukati, izvo zvinogona kugadziriswa nekuchaja uye kuburitsa activation.

3. Kupisa kusina kujairika kunokonzera kurwisana kukuru kwemukati

Bhatiri rinopisa zvisingaite panguva yekugadzira (spot welding, ultrasonic, etc.), zvichiita kuti diaphragm ibudise kuvhara kwemafuta, uye kupikisa kwemukati kunowedzera zvakanyanya.

3. Lithium bhatiri kuwedzera

1. Lithium bhatiri inoputika kana ichichaja

Kana iyo lithium bhatiri ichichajwa, iyo lithium bhatiri inongowedzera kuwedzera, asi kazhinji isingapfuuri 0.1mm, asi kuwandisa kuchaita kuti iyo electrolyte iparare, kumanikidza kwemukati kunowedzera, uye lithium bhatiri richawedzera.

2. Kuwedzera panguva yekugadzirisa

Kazhinji, kushandiswa kusina kujairika (sekupfupika, kupisa kupisa, nezvimwewo) kunoita kuti electrolyte iparadze nekuda kwekupisa kwakanyanya, uye lithium bhatiri rinoputika.

3. Wedzera paunenge uchichovha bhasikoro

Kana bhatiri richitenderedzwa, ukobvu huchawedzera nekuwedzera kwenhamba yematenderedzwa, asi haizowedzeri mushure meanopfuura makumi mashanu.Kazhinji, kuwedzera kwakajairika ndeye 0.3 ~ 0.6 mm.Iyo aluminium shell yakanyanya kuoma.Chiitiko ichi chinokonzerwa nemaitiro ebhatiri akajairika.Nekudaro, kana kukora kwegomba kuchiwedzerwa kana zvinhu zvemukati zvakaderedzwa, chiitiko chekuwedzera chinogona kuderedzwa zvakakodzera.

Chechina, bhatiri rine simba pasi mushure mekugadzira nzvimbo

Voltage yealuminium shell cell mushure mewelding yespot yakadzikira pane 3.7V, kazhinji nekuti nzvimbo yewelding ikozvino inopwanya diaphragm yemukati mesero uye mapfupi-circuits, zvichiita kuti voltage idonhe nekukurumidza.

Kazhinji, inokonzerwa nenzvimbo isina kururama welding.Nzvimbo chaiyo yewelding panofanira kunge paine ma spot welding pazasi kana padivi paine chiratidzo chekuti “A” kana “—”.Spot welding haibvumirwi padivi nerutivi rwakakura pasina kutara.Mukuwedzera, mamwe matepi echikasha-welded nickel ane urombo weldability, saka anofanira kunge ane mavara-welded nehombe yemazuva ano, kuitira kuti tepi yemukati inodzivirira tepi haigoni kushanda, zvichiita kuti mukati pfupi-kati yebhatiri yepakati.

Chikamu chekurasikirwa kwesimba rebhatiri mushure mekugadzira nzvimbo kunokonzerwa nekuzviburitsa kwebhatiri pachayo.

shanu, bhatiri rinoputika

Kazhinji, pane anotevera mamiriro kana kuputika kwebhatiri kuchiitika:

1. Kuputika kwepamusoro

Kana dunhu redziviriro risingachadzoreki kana kabhineti yekuona isiri kutonga, magetsi ekuchaja akakura kupfuura 5V, zvichiita kuti electrolyte iparare, kuita kwechisimba kunoitika mukati mebhatiri, kudzvanywa kwemukati kwebhatiri kunowedzera nekukurumidza, uye bhatiri rinoputika.

2. Overcurrent kuputika

Dunhu redziviriro harichadzoreki kana kabhineti yekuona haichadzoreki, kuitira kuti yekuchaja ikozvino yakakura uye lithium ions yakanonoka kuiswa, uye lithium simbi inoumbwa pamusoro pechigamba, inopinda mukati. diaphragm, uye iyo yakanaka uye yakaipa electrodes yakananga pfupi-inotenderera uye inokonzera kuputika (kashoma).

3. Kuputika kana ultrasonic welding plastic shell

Kana ultrasonic welding yepurasitiki shell, iyo ultrasonic simba inoendeswa kune yebhatiri musimboti nekuda kwemidziyo.Iyo ultrasonic simba rakakura zvekuti diaphragm yemukati yebhatiri inonyunguduka, uye iyo yakanaka uye isina kunaka electrode yakananga pfupi-inotenderera, zvichikonzera kuputika.

4. Kuputika panguva yekugadzira nzvimbo

Kuwedzeredza ikozvino panguva yekushongedza nzvimbo kwakakonzera kukomba kwemukati pfupi seketi kukonzera kuputika.Mukuwedzera, panguva yekugadzira nzvimbo, iyo yakanaka electrode yekubatanidza chidimbu yakabatana zvakananga kune iyo yakaipa electrode, zvichiita kuti matanda akanaka uye asina kunaka aende zvakananga kupfupi-circuit uye kuputika.

5. Pamusoro pekuputika kwekuputika

Kuwedzera-kubuda kana kupfuura-ikozvino kubuda (pamusoro pe3C) yebhatiri inonyungudika nyore nyore uye kuisa iyo yakaipa electrode yemhangura foil pane inoparadzanisa, zvichiita kuti iyo yakanaka uye yakaipa electrode iite yakananga pfupi-circuit uye kukonzera kuputika (kashoma kuitika).

6. Kuputika kana kudengenyeka kunowira

Iyo yemukati pole chidimbu chebhatiri inobviswa kana bhatiri ichizununguka zvine chisimba kana kudonhedzwa, uye yakananga pfupi-inotenderera uye inoputika (kashoma).

Yechitanhatu, bhatiri 3.6V papuratifomu yakaderera

1. Sampling isina kururama yekabhineti yekuona kana kuti isina kugadzikana yekuona kabhineti yakaita kuti nzvimbo yekuedza ive yakaderera.

2. Kudzika kwakadzika tembiricha kunokonzera yakaderera chikuva (discharge platform inokanganiswa zvakanyanya neambient tembiricha)

Zvinomwe, zvinokonzerwa nekugadzirisa kusina kunaka

(1) Fambisa electrode yakanaka yekubatanidza chidimbu chenzvimbo welding zvine simba kuti ikonzere kusabatana kweiyo positive electrode yebhatiri cell, izvo zvinoita kuti kupikisa kwemukati kwebhatiri core kukuru.

(2) Iyo nzvimbo welding yekubatanidza chidimbu haina kusimba, uye iyo yekubata kuramba yakakura, izvo zvinoita kuti bhatiri remukati rirambe rakakura.
