Intshayelelo:
Ibhetri yeLithiumibhetri esebenzisa intsimbi ye-lithium okanye i-lithium compound njengento ye-electrode. Ngenxa yeqonga eliphezulu lombane, ubunzima bokukhanya kunye nobomi benkonzo ende ye-lithium, ibhetri ye-lithium iye yaba luhlobo oluphambili lwebhetri esetyenziswa kakhulu kwi-electronics yabathengi, iinkqubo zokugcina amandla, izithuthi zombane kunye nezinye iindawo. Namhlanje, makhe siphonononge amanyathelo ambalwa okugqibela okwenziwa kwebhetri ye-lithium, i-Formation-OCV testcapacity-Separation.
Ulwakhiwo
Ukwenziwa kwebhetri yeLithium yinkqubo yokuqala yokutshaja ibhetri emva kokuba ibhetri ye-lithium izaliswe ngamanzi.
Le nkqubo inokuvula izinto ezisebenzayo kwibhetri kwaye isebenzeibhetri ye-lithium. Ngelo xesha, ityuwa ye-lithium isabela kunye ne-electrolyte ukwenza ifilimu eqinileyo ye-electrolyte interface (SEI) kwicala elibi le-electrode yebhetri ye-lithium. Le filimu inokuthintela ukwenzeka okuqhubekayo kweempendulo zecala, ngaloo ndlela inciphisa ukulahlekelwa kwe-lithium esebenzayo kwibhetri ye-lithium. Umgangatho we-SEI unempembelelo enkulu kubomi bomjikelezo, ukulahleka kwamandla okuqala, kunye nokusebenza kwezinga leebhetri ze-lithium.
Uvavanyo lwe-OCV
Uvavanyo lwe-OCV luvavanyo lwe-voltage yesekethe evulekileyo, ukuchasana kwangaphakathi kwe-AC kunye nombane wegobolondo weseli enye. Iyinxalenye ebaluleke kakhulu yenkqubo yokuvelisa ibhetri. Kufuneka ihlangabezane nokuchaneka kwe-OCV ye-0.1mv kunye nokuchaneka kombane wegobolondo we-1mv. Uvavanyo lwe-OCV lusetyenziselwa ukuhlela iiseli.
Inkqubo yokuvelisa uvavanyo lwe-OCV
Uvavanyo lwe-OCV ikakhulu lulinganisa iimpawu zebhetri ngokucinezela iiprobe eziqhagamshelwe kwisivavanyi sombane kunye nesivavanyi sangaphakathi sokuxhathisa kwiindlebe ezilungileyo nezingalunganga zebhetri yepakethe ethambileyo.
Uvavanyo lwe-OCV lwangoku luvavanyo lwe-semi-automatic. Umsebenzi ubeka ibhetri ngesandla kwisixhobo sovavanyo, kwaye i-probe yesixhobo sovavanyo inxibelelana neendlebe zebhetri ezilungileyo nezingalunganga ukwenza uvavanyo lwe-OCV kwibhetri, kwaye emva koko wothula ngesandla kwaye uhlele ibhetri.
Ukwahlulwa kwamandla ebhetri yeLithium
Emva kwebhetshi yeiibhetri ze-lithiumzenziwe, nangona ubukhulu bufana, umthamo weebhetri uya kwahluka. Ngoko ke, kufuneka bahlawulwe ngokupheleleyo kwisixhobo ngokweenkcukacha, baze bakhululwe (bakhutshwe ngokupheleleyo) ngokwexesha elichaziweyo. Ixesha elithathiweyo ukukhupha ibhetri liphindaphindwe ngokupheleleyo ngumthamo webhetri.
Ngethuba nje umthamo ovavanyiweyo udibana okanye udlula umthamo owenziweyo, ibhetri ye-lithium ifanelekile, kwaye ibhetri engaphantsi komthamo owenziweyo ayikwazi ukuthathwa njengebhetri efanelekileyo. Le nkqubo yokukhetha iibhetri ezifanelekileyo ngokuvavanywa komthamo ibizwa ngokuba kukwahlulwahlulwa kwamandla.
Indima yeibhetri ye-lithiumukwahlula amandla akuncedi kuphela ukuzinza kwefilimu ye-SEI, kodwa kunokunciphisa ixesha elichithwa yinkqubo yokwahlula amandla, ukunciphisa ukusetyenziswa kwamandla kunye nokwandisa umthamo wokuvelisa.
Enye injongo yolwahlulo lwamandla kukuhlela kunye neqela leebhetri, oko kukuthi, ukukhetha ii-monomers ezinokumelana okufanayo kwangaphakathi kunye nomthamo wokudibanisa. Xa kudityaniswa, kuphela abo banentsebenzo efanayo kakhulu abanokwenza ipakethi yebhetri.
Ukuqukumbela
Ekugqibeleni, iibhetri ye-lithiumigqibezele zonke iinkqubo zeseli yebhetri emva kokuhlolwa kwenkangeleko epheleleyo, ukutshiza kwekhowudi yebakala, ukuphononongwa komgangatho wokuskena, kunye nokupakishwa, ilindele ukuhlanganiswa kwipakethi yebhetri.
Ngokuphathelele iipakethi zebhetri, ukuba unombono weepakethi zebhetri ye-DIY, i-Heltec ibonelelaabavavanyi umthamo webhetriukukuvumela ukuba uqonde iiparamitha zebhetri yakho kwaye ucinge ukuba ifanelekile na ukudibanisa ipakethi yebhetri oyifunayo. Sikwabonelelaisilinganisi sebhetriukugcina iibhetri zakho ezindala kunye nokulinganisela iibhetri ngentlawulo engalinganiyo kunye nokukhupha ukuphucula ukusebenza kwebhetri kunye nobomi.
I-Heltec Energy liqabane lakho elithembekileyo kwimveliso yeebhetri. Ngokujolisa kwethu okungapheliyo kuphando kunye nophuhliso, kunye noluhlu lwethu olubanzi lwezincedisi zebhetri, sinikezela ngezisombululo zokuphela konyaka ukuhlangabezana neemfuno eziguqukayo zeshishini. Ukuzibophelela kwethu ekugqweseni, izisombululo ezilungiselelweyo, kunye nentsebenziswano eyomeleleyo yabathengi kusenza ukuba sikhethe ukukhetha abavelisi beebhetri kunye nababoneleli kwihlabathi liphela.
