Hlela ukwakheka kwebhetri yeeseli zeCoin

Ubomi bemihla ngemihla, imfuno yethu yebhetri yeqhosha nayo inkulu kakhulu, iindidi zeethoyizi, ulawulo olukude lwemoto kunye nezinye iimveliso zombane ziya kusebenzisa le bhetri encinci yeqhosha, nangona ziya kusetyenziswa, kodwa abantu abaninzi baqhelekile kwaye abaqhelananga neebhetri zeqhosha. , namhlanje ndiza kukunika ukuthandwa.
Iqhosha ibhetri intshayelelo esisiseko.
Ibhetri yelithium-ion iqhosha lenziwe ikakhulu liqokobhe elilungileyo, iqokobhe elingalunganga, (elilungileyo / elingalunganga) isiqwenga sepali, i-diaphragm, i-gasket, i-shrapnel, i-electrolyte, njl.
I-CR2032 kwibhetri yesiqhelo esetyenziswa ngokuqhelekileyo iqhosha lempahla yexabiso C ibonisa isibonda esilungileyo uMno2, uchungechunge lweBR, uB lubonisa i-pole fluorocarbon.I-c okanye i-B imele inkqubo ye-buckle, u-R umele ubume bebhetri bungqukuva.Amadijithi amabini okuqala yi-diameter (iyunithi mm), kwaye idijithi ezimbini zokugqibela bubukhulu (iyunithi 0.1mm), ithatha amanani amabini asondeleyo.Umzekelo, ubungakanani obuqikelelwayo be-CR2032 yi-20mm ububanzi kunye ne-3.2mm ngobukhulu.

Ingqekembe yebhetri yeseli

1 iqhosha le cell case

Iqokobhe leseli yeqhosha le-CR2032, iqokobhe eliqinisekileyo likhulu, iqokobhe elingalunganga lesakhiwo somnatha, lincinci, ngoko inkqubo yendibano ngokubanzi iqala ngeqokobhe elingalunganga.

2 Iqhekeza lepali

Inkqubo yokulungiselela i-electrode inempembelelo ebalulekileyo malunga nokuba ukusebenza kwe-electrochemical kunokuphuhliswa ngokupheleleyo.
Inkqubo yokulungiselela i-electrode yebhubhoratri ngokuqhelekileyo ihlukaniswe kwiinkqubo ezimbini: ukuxuba kunye nokugqoka.Inkqubo yokuxuba ibandakanya indlela yokugaya i-manual kunye nendlela yokuxuba i-slurry mechanical, kunye nenkqubo yokugqoka i-manual kunye nokugubungela ngomatshini.
Inkqubo yokuxuba isekelwe kwisixa sezinto ezibonelelweyo ukugqiba ukusetyenziswa kokugaya ngesandla okanye indlela yokucoca i-mechanical slurry, isixa se-slurry esixutywe ngexesha kwi-laboratory silinganiselwe, ngokuqhelekileyo sisebenzisa i-coating manual, xa i-slurry yanele ukusebenzisa i-slurry. umatshini wokugquma omncinci.Yonke inkqubo yokuvelisa kufuneka iqhutywe kwindawo eyomileyo, izixhobo kunye nezixhobo ezisetyenzisiweyo kufuneka zigcinwe zomile, ngoko ukuveliswa kweebhetri akunakusetyenziselwa ixesha elide ukugcina isiqwenga sesibonda.

I-3 diaphragm
I-diaphragm esetyenziswa kwilabhoratri ngokuqhelekileyo yiCelgard 2400 okanye ezinye iimveliso zoluhlu lweCelgard.Emva kokunyathela kwiziqwenga ezincinci ezingqukuva, ububanzi bukhulu kancinci kunee-electrode ezilungileyo nezingalunganga.Iidiaphragms zinokukhethwa ngokweemfuno zokusebenza kwebhetri.

Yintoni injongo yediaphragm?

Ukubeka ngokulula, ukuba akukho diaphragm, i-electrode ekhangayo kunye nengalunganga inxibelelana ngokuthe ngqo, oko kukuthi i-short-circuiting, yiyo loo nto ezinye iiseli zeqhosha zithintelwa ekuveliseni iikristale ze-lithium dendritic, ukuze zibathintele ekugqobhozeni i-diaphragm, kubangele a isiphaluka esifutshane sengingqi kunye nesiphumo sengozi yokhuseleko.I-diaphragm isetyenziswa ngokubanzi i-polyethylene kunye nezinye izinto ze-polymer, ezingenayo i-conductive, isakhiwo sayo sinezinto ezininzi ze-microporous, ezivumela i-lithium ion ngokusebenzisa, nangona i-insulator, kodwa ayivumeli i-electron ngokusebenzisa inkcazo ayichanekanga.

Iphepha le-lithium eli-4 (okt ishidi elibi)
Idayamitha yeshidi eNegative incinci kancinane kunedayamitha yeqokobhe elibi, CR2032 lithium sheet ububanzi be-15.8mm, ilabhoratri idla ngokusebenzisa ububanzi be-14mm ehambelana neqhosha leseli ye-CR2032) stamping die stamping positive sheet.Kuyaphawuleka ukuba i-lithium sheet ithambile kwaye ikhubazekile ngokulula, ngoko ke ngaphambi kokufaka ibhetri, ungasebenzisa iqokobhe elilungileyo (kuba likhulu ngokwentelekiso) ukuthambisa i-lithium sheet.Ukongezelela, isinyithi se-lithium kulula u-oxidize kwaye siwohloke emoyeni kwaye siqhume ngokulula emanzini, ngoko ke i-lithium metal sheet ethengiweyo kufuneka ivulwe kwibhokisi yeglavu.Qaphela ukuba ungonakalisi iglavu xa uvula.

5 iGasket
I-gasket yiphepha elijikelezayo le-aluminium kunye nobukhulu obufanayo nobukhulu bephepha le-lithium.Kuvavanyo, iinkcukacha ezahlukeneyo kunye nobukhulu bunokuthengwa njengoko kufuneka.
Qaphela: I-gasket, iigobolondo ezintle kunye nezibi kunye nezinye izinto kufuneka zihlambuluke ngotywala ngokuphindaphindiweyo nge-ultrasonic ngaphambi kokusetyenziswa, kwaye zomiswe nge-oven yokumisa.

I-6 Shrapnel (iqhekeza lenkxaso)
ISrapnel isetyenziswa ikakhulu ukuxhasa ibhetri.Ngaphandle kwe-shrapnel, ibhetri iya kuba tyaba kakhulu kwisinyathelo seseli yoxinzelelo kwaye izinto zangaphakathi zinokutyunyuzwa.I-shrapnel yongezwa kwicala elibi kuphela, kodwa ukuba i-shrapnel yongezwa kwicala elilungileyo nelibi, i-buckling ayikwazi ukuvalwa ngexesha lesinyathelo seseli yoxinzelelo, okubangela ukuba i-electrolyte idibane nomoya kunye novavanyo olungaphumeleli.

7 Electrolyte.
Izinto ezahlukeneyo ngokubanzi zihambelana nee-electrolyte ezahlukeneyo, ungazami ukugcina ingxaki kuvavanyo, amanani amancinci e-electrolyte angacelwa kwinkampani, kwaye aya kunikwa ngokubanzi.I-electrolyte ekhethekileyo yomntu ngamnye, njenge-electrolyte ephantsi yobushushu, inokufuna ukuthengwa, kwaye ixabiso alikho phantsi.

Kutshanje, ixabiso lemarike lezinto ezahlukeneyo liye landa kakhulu, kodwa alichaphazeli ukuveliswa kwebhetri yethu, ukuba ufuna iseli yeqhosha, wamkelekile ukudibana neLiyuan Battery Technology.
