MaTabs muPouch Lithium-Ion Mabhatiri: Pfupiso Yakakwana

MaTab zvinhu zvakakosha mumabhatiri e lithium-ion, anoshanda semabhiriji anofambisa magetsi pakati pema electrode emukati mebhatiri nemaseketi ekunze. Kupfuura kungobatanidza chete, anoita basa rakakosha mukuona kuchengetedzeka kwebhatiri, kushanda kwekuvhara, uye kushanda zvakanaka kwese. Chinyorwa chino chinoongorora mhando, zvinhu, hunhu hwekushanda, uye mashandisirwo ezvikamu izvi zvakakosha, zvichipa ruzivo rwakakosha kune vagadziri nemainjiniya.

Chii Chinonzi Mabhatiri?

Pakati pawo, mabheteri ematabhu imhando yezvivakwa zvine zvikamu zviviri zvakakosha: simbi strip nepurasitiki firimu (tab glue). simbi strip inoshanda semuchina wekufambisa magetsi, ichifambisa magetsi pakati pemaelectrode akanaka/asina kunaka ebhatiri nemidziyo yekunze. Panguva iyi, firimu repurasitiki rinopa chisimbiso chekudzivirira kubuda kwe electrolyte uye rinodzivirira simbi kubva kuma short circuits.

1. Mathebhu akanakadzinowanzogadzirwa nearuminiyamu (Al) nekuda kwekugona kwayo kupinza mvura zvakanaka uye kuramba kwayo ngura.
2. Matebhu asina kunakashandisai nickel (Ni) kana nickel-plated copper (Ni-Cu). Nickel tabs dzakajairika mumidziyo midiki yedhijitari, nepo nickel-plated copper tabs—dzinokosheswa nekuda kwekugona kwadzo kutakura magetsi akawanda—dzinofarirwa pamabhatiri emagetsi uye mashandisirwo adzo epamusoro.

Kupatsanurwa kweTabs

Matabhu anorongwa zvichienderana nezvinhu zvawo, rudzi rwekunamira, uye kurongedza, rimwe nerimwe rinokodzera mashandisirwo chaiwo:

1. Nesimbi Strip Material

1. Matabhu eAruminiyamu (Al): Inonyanya kushandiswa pamaerekitironi akanaka. Anogonawo kushanda seerekitironi asina kunaka mumabhatiri ane lithium titanate anodes.
2. Matabhu eNickel (Ni): Inoshanda chete kune maerekitironi asina simba mumidziyo ine simba shoma senge mafoni, mapiritsi, uye mabhangi emagetsi.
3. Nickel-plated mhangura (Ni-Cu) tabs: Yakagadzirirwa maerekitirodhi asina kunaka mumabhatiri emagetsi (semuenzaniso, mota dzemagetsi) uye mabhatiri ane mwero wepamusoro, ichibatanidza conductivity yemhangura nekudzivirira ngura kwenickel.

2. Nemhando yeTab Adhesive

Misika yemuno inoronga manamatidziro ematabhu neruvara, zvichiratidza kusiyana kwemhando uye mashandisirwo:

1. Matabhu matema anonamira: Inoshandiswa mumabhatiri edhijitari ari pakati nepakati. Maumbirwo awo (musoro wefirimu rePEN une zvikamu zvePP zvakagadziriswa) anogona kukanganisa kucheneruka nekufamba kwenguva.
2. Matabhu ane namatidza eyero: Inowanikwa mumabhatiri emagetsi ari pakati nepakati. Kunyange zvazvo zviri nyore kuvhara, simbi yavo isina kurukwa inogona kunwisa hunyoro, zvichiita kuti bhatiri rizvimbe.
3. Matabhu machena anonamira: Zvinonyanya kushandiswa pamidziyo yedhijitari yepamusoro-soro, mabhatiri emagetsi, uye mabhatiri ane mwero wepamusoro. Zvinowanikwa mumhando imwe chete, nhatu, kana shanu, zvinonamira zvichena zvine mativi matatu (zvine PP cores) zvinopa sealing yepamusoro uye hazvina njodzi yekubvisa dhayi.
4. Matebhu akamonerwa: Zvidimbu zvinoramba zvichimonerwa kuita mipumburu, zvakanakira mitsetse yekugadzira otomatiki.
5. Matabhu epepa: Matabhu akarongwa pakati pemapepa epurasitiki, akakodzera kushandiswa nemaoko kana kuti nemaitiro ekugadzira otomatiki.

3. Nekurongedza

1. Matebhu akamonerwa: Zvidimbu zvinoramba zvichimonerwa kuita mipumburu, zvakanakira mitsetse yekugadzira otomatiki.
2. Matabhu epepa: Matabhu akarongwa pakati pemapepa epurasitiki, akakodzera kushandiswa nemaoko kana kuti nemaitiro ekugadzira otomatiki.

Zvinhu Zvinokosha uye Mashandiro

Kushanda kwematabhu kunoenderana zvakanyanya nezvinhu zviri mukati mawo:

1. Zvidimbu zvesimbi: Aruminiyamu (AL1050 alloy) uye mhangura (TU1 mhangura isina oxygen) zvinofarirwa nekuda kwekufambisa kwadzo, kugona kwadzo kufamba, uye kuramba ngura. Kuisa nickel plating pamitsetse yemhangura kunodzivirira oxidation uye kunowedzera kugona kwayo kusungirira.
2. Zvinonamira zvetabhu: Zvinonamira zvakawanda zvinotengwa kubva kuJapan, sezvo zvinhu zvePP zvemuno zvichinetseka kusangana nezvinodiwa nehuremu hwemamorekuru. Zvinonamira zvemhando yepamusoro (semuenzaniso, zvinonamira zvichena zvine mativi matatu) zvinodzivirira kupisa (nzvimbo yekunyunguduka ~147°C) uye kuchinjika, zvichiita kuti zvive nechokwadi chekunamira kwakavimbika nemafirimu epurasitiki ealuminium.

Kugadzira uye Kudzora Hunhu

Kugadzira ma tabo ane mashandiro epamusoro kunoda kunyatsorongeka:

1. Maitiro ekuisa jira: Matabhu emhangura akafukidzwa nenickel anoshandisa electroplating (ukobvu hwe1.8±0.3μm) kana electroless plating (ukobvu hwe1.0±0.3μm) kuti ive nechokwadi chekuti yakafukidzwa zvakaenzana.
2. Kucheka mucheto: Zvidimbu zvesimbi zvakakora kupfuura 0.2mm zvinoda kuchekererwa kwemucheto kudzivirira matambudziko ekudzivirira kupisa uye njodzi yekubuda kwemvura.
3. Kuedza kwakasimba:
   1. Kuyedzwa kwekunyudzwa kweElectrolyte: Matabhu anofanira kuchengetedza simba rechisimbiso >15N/15mm mushure memaawa makumi maviri nemana pa85°C.
   2. Miedzo yekukombama: Matabhu anofanira kumira akakombama 5-7 (zvichienderana nekukora) kuti ave nechokwadi chekuti acharamba aripo munzvimbo dzinodedera (semuenzaniso, mota dzemagetsi).

Nzira dzekubatanidza Tab

Kubatanidza ma tabo kuma circuits ekunze kunosanganisira matekiniki akati wandei:

1. Kusunga kwemuchina: Kuboora nekukurura zvinopa kubatana kwakasimba uye kwakachipa asi zvinoda kungwarira pakukora.
2. Kubatanidza: Solder yeM51 inodziya zvishoma inoshanda kune simbi dzakasiyana (semuenzaniso, mhangura nearuminiyamu) asi inodhura.
3. Kushongedza kweultrasonic: Nzira inonyanya kufarirwa yemabhatiri emagetsi, uchishandisa ma "high-frequency vibration" kubatanidza ma "tab foil" matete (0.01mm) pasina kupisa kwakanyanya.

Mhedziso

Matabhu anogona kunge ari madiki, asi dhizaini yawo uye hunhu hwawo zvinokanganisa mashandiro ebhatiri repachikwama. Sezvo kudiwa kwemabhatiri akachengeteka uye anoshanda zviri nani mumotokari dzemagetsi uye kuchengetwa kwesimba kuri kuwedzera, kufambira mberi kwezvinhu zvetabhu (semuenzaniso, maglues ane layer yakawanda) uye kugadzirwa (semuenzaniso, kuputira kwakanyatsojeka) kucharamba kuri kukosha. Kunzwisisa hunhu hwetabhu ndiko kwakakosha pakuvandudza kuvimbika kwebhatiri uye kugara kwenguva refu mumashandisirwo akasiyana-siyana.
