Loluphi uhlobo lwebhetri ye-lithium olungcono kugcino lwesibane sesitrato selanga?

Izibane zesitalato zeSolarngoku zibe zezona ndawo ziphambili zokukhanyisa kwiindlela zasedolophini nasezilalini. Zilula ukuzifaka kwaye azidingi i-wiring eninzi. Ngokuguqula amandla okukhanya abe ngamandla ombane, aze ke aguqule amandla ombane abe ngamandla okukhanya, azisa isiqwenga sokukhanya ebusuku. Phakathi kwazo, iibhetri ezinokutsha kunye nezikhutshiweyo zidlala indima ebalulekileyo.

Xa kuthelekiswa nebhetri ye-lead-acid okanye i-gel ibhetri kwixesha elidlulileyo, ibhetri ye-lithium esetyenziswa ngokuqhelekileyo ngoku ingcono ngokumalunga namandla athile kunye namandla athile, kwaye kulula ukuqaphela ukutshaja okukhawulezayo kunye nokukhutshwa okunzulu, kwaye ubomi bayo bude, ngoko ke kusizisela amava angcono wesibane.

Noko ke, kukho umahluko phakathi kokulungileyo nokubiiibhetri ze-lithium. Namhlanje, siza kuqala ngefomu yabo yokupakisha ukubona ukuba zeziphi iimpawu zezi bhetri ze-lithium kwaye yintoni engcono. Ifom yokupakisha ihlala ibandakanya i-cylindrical winding, i-square stacking kunye ne-square winding.

1. Uhlobo lwe-Cylindrical winding

Oko kukuthi, ibhetri yecylindrical, eyisilungiselelo sebhetri yeklasiki. I-monomer ikakhulu iqulunqwe ngee-electrode ezilungileyo kunye ezimbi, i-diaphragms, abaqokeleli abalungileyo nababi, iivalvu zokhuseleko, izixhobo zokukhusela ezidlulayo, iinxalenye zokugquma kunye namaqokobhe. Kwinqanaba lokuqala leqokobhe, kwakukho iigobolondo ezininzi zentsimbi, kwaye ngoku kukho iigobolondo ezininzi ze-aluminium njengezinto eziluhlaza.

Ngokobukhulu, ibhetri yangoku iquka i-18650, 14650, 21700 kunye nezinye iimodeli. Phakathi kwabo, i-18650 yeyona ixhaphakileyo kwaye ikhulile.

2. Uhlobo lwesikwere

Lo mzimba webhetri enye ubukhulu becala uqulunqwe sisigqubuthelo esingaphezulu, iqokobhe, ipleyiti elungileyo, ipleyiti engalunganga, i-diaphragm lamination okanye i-winding, insulation, izinto zokhuseleko, njl., kwaye iyilwe ngesixhobo sokukhusela inaliti (NSD) kunye nesixhobo sokukhusela ukhuseleko olungaphezulu. OSD). Iqokobhe kwakhona ubukhulu becala iqokobhe lentsimbi kwinqanaba lokuqala, kwaye ngoku iqokobhe lealuminiyam iye yaba yeyona nto iphambili.

3. Isikwere sipakishwe

Oko kukuthi, ibhetri yepakethe ethambileyo esihlala sithetha ngayo. Isakhiwo esisisiseko sale bhetri sifana nezi ntlobo zimbini zingasentla zeebhetri, eziqulunqwe ngama-electrode afanelekileyo kunye ne-negative, i-diaphragm, i-insulating material, i-electrode lug kunye negobolondo elibi. Nangona kunjalo, ngokungafaniyo nohlobo olujikelezayo, olusekwe ngokujija iipleyiti ezichanekileyo kunye nezingalunganga, ibhetri yohlobo olulaminethiweyo yenziwa ngokulayita iileyile ezininzi zeepleyiti ze-electrode.

Iqokobhe ikakhulu ifilimu yeplastiki yealuminiyam. Umgangatho ongaphandle wesi sakhiwo se-nayiloni, umaleko ophakathi yifoyile ye-aluminium, umaleko wangaphakathi ngumaleko wetywina lobushushu, kwaye umaleko ngamnye udityaniswe ne-adhesive. Esi sixhobo sine-ductility elungileyo, ukuguquguquka kunye namandla omatshini, kwaye sinomqobo ogqwesileyo kunye nokusebenza kwetywina lobushushu, kwaye sinokumelana kakhulu nesisombululo se-electrolytic kunye ne-asidi eyomeleleyo.

Kufuphi

I-1) Ibhetri ye-cylindrical (uhlobo lwe-cylindrical winding) ngokuqhelekileyo yenziwe ngegobolondo yensimbi kunye ne-aluminium shell. Itekhnoloji evuthiweyo, ubungakanani obuncinci, amaqela aguqukayo, ixabiso eliphantsi, itekhnoloji evuthiweyo kunye nokungaguquguquki okuhle; Ukutshatyalaliswa kobushushu emva kokwahlulahlula kuyilo olulambathayo, ubunzima bobunzima kwaye buphantsi kumandla athile.

I-2) Ibhetri yesikwere (uhlobo lwe-square winding), uninzi lwazo lwaluyi-shell shells kwinqanaba lokuqala, kwaye ngoku iigobolondo ze-aluminium. Ukutshatyalaliswa kobushushu obuhle, ukuyila ngokulula kumaqela, ukuthembeka okulungileyo, ukhuseleko oluphezulu, kuquka ivalve yobungqina bokuqhuma, ubunzima obuphezulu; Yenye yeendlela eziphambili zobugcisa ezineendleko eziphezulu, iimodeli ezininzi kwaye kunzima ukudibanisa inqanaba lobuchwepheshe.

I-3) Ibhetri ye-soft pack (uhlobo lwe-square laminated), kunye nefilimu ye-aluminium-plastiki njengephakheji yangaphandle, iguquguqukayo ekutshintsheni ubungakanani, iphezulu kumandla athile, ukukhanya kwisisindo kunye nokuncinci ekuchaseni kwangaphakathi; Amandla omatshini ambi kakhulu, inkqubo yokutywina inzima, ulwakhiwo lweqela luntsonkothile, ukuchithwa kobushushu akwenziwanga kakuhle, akukho sixhobo sokuthintela uqhushumbo, kulula ukuvuza, ukuhambelana akubi kakuhle, kwaye iindleko zikho. phezulu.
