Izilumkiso zokuSetyenziswa kunye neNdibano yeeSeli zebhethri ze-Polymer Lithium

  Ibhetri yePolymer ikwaluhlobo lwebhetri ye-lithium-ion, kodwa xa kuthelekiswa nebhetri ye-lithium ion (i-Li ion), ineenzuzo ezininzi ezicacileyo, ezinje ngoxinaniso lwamandla aphezulu, i-miniaturization, i-ultra-thin, lightweight, ukhuseleko oluphezulu njalo njalo. Ludidi olutsha lwebhetri. Ngokumalunga nokuma, iibhetri ze-lithium ze-polymer zineempawu ze-ultra-thin, kwaye zingenziwa kwiibhetri zaso nasiphi na isimo kunye namandla okuhlangabezana neemfuno zeemveliso ezahlukeneyo.

  Ibhetri yePolymer luhlobo lwebhetri ye-lithium enegel electrolyte kunye nokupakishwa okuguquguqukayo. Ihlala ibizwa ngokuba yibhetri ye-lithium ethambileyo kwimarike yoluntu, eyenza ibhetri ye-lithium yahluke kwibhetri ye-lithium-ion eqhelekileyo. Ngoko ke, kukho izilumkiso ezithile ezikhethekileyo. Ezi zilumkiso zilandelayo zibekwe phambili malunga nezenzo ezingachanekanga ezinokubakho ngexesha lokusetyenziswa kunye nokudibanisa iseli.

  Ngokumalunga nokusetyenziswa kweentsimbi zombane, kubandakanya ukukhuselwa kwefilimu edibeneyo ye-aluminium-iplastiki, ukutywinwa komphetho ophezulu (ukutywinwa komphetho ekupheleni kwesibambo), ukutywinwa kwecala, isibambo kunye nemilinganiselo yokuphepha impembelelo yomatshini kunye nesiphaluka esifutshane. .

  1. Ifilimu ye-aluminium yeplastiki edibeneyo yokukhusela i-package yangaphandle yokukhusela: ngokukodwa ukuphepha ukonakala ngamalungu abukhali. Ngesi sizathu, indawo engqongileyo yebhetri kufuneka icocwe amaxesha ngamaxesha. Iindawo ezibukhali azivumelekanga ukuba zidibane okanye zingqubane nebhetri. Iiglavu zinokunxitywa xa uzithatha ukuthintela ukukrwela umphezulu weseli yebhetri ngeminwe.

  2. Ukukhuselwa kokutywinwa kwecala eliphezulu kunye necala: ukwenzela ukuba ugweme umonakalo kwiindawo eziphezulu kunye necala kunye nokonakalisa umphumo wokutywinwa, akuvunyelwe ukugoba phezulu kunye necala; Ngelo xesha, ukutyunjwa okuthembekileyo kunye namanyathelo okuzihlukanisa kufuneka kuthathwe ekuyilweni kwesiseko sombane ukuphepha isiphaluka esifutshane phakathi kwe-electrode engalunganga kunye nefilimu edibeneyo ye-aluminium-plastiki.

  3. Ukhuseleko lomqheba wepali: isiphatho sepali se-aluminiyam sisetyenziswa njengetheminali ephumayo yepolymer yelithium yebhetri, kwaye isiphatho sepali yenickel sisetyenziswa njengetheminali ephumayo engalunganga. Njengoko isiphatho sepali sibhityile, akuvumelekanga ukugotywa; Kwangaxeshanye, kunqande unxibelelwano phakathi kwesibambo sepali kunye nefilimu ehlanganisiweyo ye-aluminium-plastiki ngexesha lenkqubo yokuvelisa, kwaye uhlukanise ngokungqongqo kunye nefilimu ye-ferrule.

  4. Kuphephe ukuchaphazeleka ngoomatshini, njengokuwa, ukubetha, ukugoba iseli kunye nokunyathela ngempazamo ibhetri.

  5. Akuvunyelwe ukusebenzisa izinto zetsimbi okanye iingcingo kwisiphaluka esifutshane i-electrodes efanelekileyo kunye ne-negative.

  Emva kokuba iseli igqityiwe, inyathelo elilandelayo kukudibanisa ngokuchanekileyo kunye negobolondo kunye nemodyuli yesekethe yokukhusela iseli ukwenza ibhetri yepolymer. Izilumkiso kule nkqubo ziquka:

1. Uyilo lwezindlu:

(1) Amandla aneleyo omatshini ukunqanda umonakalo wangaphandle kwiseli,

(2) Xa iseli yombane ifakwe kwiqokobhe, thintela imiphetho ebukhali kunye neekona zeqokobhe ukukrwela iseli yombane;

(3) Thintela i-aluminium-iplastiki edibeneyo yefilimu yesangweji ye-aluminium ecocekileyo ukusuka kwisiphaluka esifutshane ngenxa yoqhagamshelwano lwangaphandle.

  2. Isiphaluka sokukhusela iiseli kufuneka siyilwe: kubandakanywa ukusetwa kwenzululwazi yobuninzi / ubuncinci be-voltage, ukukhuselwa kwe-overcurrent, kunye ne-overcharge kunye nokukhuselwa kokukhutshwa kweyunithi yebhetri (iseli enye) yokusetyenziswa ngokudibeneyo kweeseli.

  3. Ukuhanjiswa kwe-electrode ye-aluminium ene-positive nge-nickel strip kunye nokudibanisa phakathi kombane ongundoqo kunye nebhodi yesekethe iya kuphunyezwa nge-ultrasonic welding okanye i-spot welding technology.

  4. Ukuma okuthembekileyo kwiseli yebhetri. Emva kokuhlanganisana, iseli yebhetri iya kuqiniswa ngokuqinileyo kwigobolondo kwaye ayiyi kuhamba, ukwenzela ukuba yonke i-lithium ibhetri yesakhiwo ibe kwimeko edibeneyo.

5. Ibhokisi yebhetri mayihlulwe kwibhetri nge -epoxy sheet ye-3240 ukuthintela i-short circuit kunye nokuvuza. Ukuba uyoyika ukushukuma, ungasebenzisa i-pearl foam (uhlobo oluzisa kwibhokisi yekhompyutha yakho) ukuthintela iinyikima.

  6. ngenxa yokungabi namanzi, i-outlet kunye ne-handle yebhokisi ivalwe nge-rubber ye-silicone ye-704.
