Mabhatiri eTernary lithium uyemabhatiri esimbi e-lithium phosphateNdiwo marudzi maviri makuru emabhatiri e lithium anoshandiswa zvakanyanya pari zvino mumotokari dzemagetsi, masisitimu ekuchengetera simba nezvimwe zvishandiso zvemagetsi. Asi wanzwisisa here hunhu hwavo nekusiyana kwavo? Kuumbwa kwavo nemakemikari, hunhu hwekushanda kwavo uye nzvimbo dzekushandisa zvakasiyana zvakanyanya. Ngatidzidzei zvakawanda nezvavo neHeltec.
Kuumbwa kwezvinhu:
Bateri reTernary lithium: Chinhu che positive electrode chinowanzova nickel cobalt manganese oxide (NCM) kana nickel cobalt aluminum oxide (NCA), iyo inoumbwa ne nickel, cobalt, manganese kana nickel, cobalt, aluminum nezvimwe zvinhu zvesimbi oxides, uye negative electrode inowanzova graphite. Pakati pazvo, chiyero che nickel, cobalt, manganese (kana aluminum) chinogona kugadziriswa zvichienderana nezvinodiwa chaizvo.
Bhatiri reLithium iron phosphate: lithium iron phosphate (LiFePO₄) inoshandiswa sechinhu che positive electrode, uye graphite inoshandiswawo kune negative electrode. Kuumbwa kwayo kwemakemikari kwakasimba, uye haina simbi dzinorema nesimbi dzisingawanzoonekwi, izvo zvine hushamwari kune zvakatipoteredza.
Kushanda kwekuchaja nekuburitsa:
Bhatiri reTernary lithium: rinomhanyisa kushaja nekubuda nekukurumidza, rinogona kuchinjika pakushaja nekubuda nekukurumidza, rakakodzera michina nemamiriro ezvinhu ane zvinodiwa zvepamusoro zvekumhanya kwekushaja, senge mota dzemagetsi dzinotsigira kushaja nekukurumidza. Munzvimbo ine tembiricha yakaderera, mashandiro ayo ekushaja nekubuda zvakanakawo, uye kurasikirwa kwesimba kudiki.
Bhatiri reLithium iron phosphate: kushaja zvishoma nezvishoma uye kumhanya kwekuburitsa, asi kushaja kwebhatiri uye kushanda kwaro kwakasimba. Inogona kutsigira kushaja kwepamusoro uye inogona kuchajwa zvizere muawa imwe nekukurumidza, asi kushanda kwaro nekushaja kazhinji kunenge kuri pa80%, izvo zvakaderera zvishoma pane ternary lithium battery. Kana tembiricha yakaderera, kushanda kwayo kunoderera zvakanyanya, uye mwero wekuchengetedza kugona kwebhatiri ungangove 50%-60%.
Kuwanda kwesimba:
Bhatiri reTernary lithium: Simba rayo rakanyanya kuwanda, rinowanzo svika kupfuura 200Wh/kg, uye zvimwe zvigadzirwa zvepamusoro zvinogona kudarika 260Wh/kg. Izvi zvinobvumira mabhatiri eTernary lithium kuchengetedza simba rakawanda pahuwandu kana huremu hwakafanana, zvichipa daro refu rekutyaira rezvishandiso, zvakaita semota dzemagetsi, dzinogona kutsigira mota kufamba daro refu.
Bhatiri reLithium iron phosphate: Simba rayo rakaderera, kazhinji kacho riri pakati pe110-150Wh/kg. Saka, kuti mabhatiri eLithium iron phosphate akwanise kushanda zvakanaka, mabhatiri eLithium iron phosphate anogona kuda vhoriyamu yakakura kana huremu.
Hupenyu hwekufamba kwesero:
Bhatiri reTernary lithium: Hupenyu hwebhatiri hupfupi, uye nhamba yekutenderera kwedata inokwana ka2,000. Pakushandiswa chaiko, simba rayo rinogona kunge rakaora kusvika pa60% mushure memabhatiri chiuru. Kushandiswa zvisina kunaka, sekuchaja zvakanyanya kana kuburitsa, uye kushandiswa munzvimbo dzinopisa zvakanyanya, kuchakurumidzisa kuora kwebhatiri.
Bhatiri reLithium iron phosphate: Rinogara kwenguva refu, rine machaji anodarika 3,500 uye madhiraivha anobuda, uye mamwe mabhatiri emhando yepamusoro anogona kusvika kanopfuura 5,000, izvo zvakaenzana nemakore anopfuura 10 ekushandiswa. Rine lattice stability yakanaka, uye kuiswa nekubvisa maion eLithium hazvina zvazvinobatsira pa lattice, uye rinogona kudzoserwa kumashure zvakanaka.
Kuchengetedzeka:
Bateri yeTernary lithium: kugadzikana kwekupisa kusina kunaka, kuri nyore kukonzera kupisa kutiza kana tembiricha yakakwira, kudzvanya zvakanyanya, short circuit nezvimwe zvinhu, zvichikonzera njodzi yakakura yekutsva kana kutoputika. Zvisinei, nekufambira mberi kwetekinoroji uye kusimbiswa kwematanho ekuchengetedza, akadai sekushandisa masisitimu ekutarisira mabhatiri epamusoro uye kugadzirisa chimiro chebhatiri, kuchengetedzeka kwayo kuri kuramba kuchivandudzwa.
Bhatiri reLithium iron phosphate: kugadzikana kwakanaka kwekupisa, zvinhu zvakanaka zveelectrode hazvibudisi okisijeni nyore pakupisa kwakanyanya, uye hazvizotanga kuora kusvika 700-800℃, uye hazviburitse mamorekuru eokisijeni kana zvasangana nekukandwa, kuboorwa, short circuit nedzimwe mamiriro ezvinhu, uye hazviwanzo kupiswa zvine simba, zvine mashandiro ekuchengetedza akakwirira.
Mutengo:
Bateri reTernary lithium: nekuti electrode yakanaka ine zvinhu zvinodhura zvesimbi zvakaita senickel necobalt, uye zvinodiwa pakugadzira zvinhu zvakakwirira, uye zvinodiwa nezvakatipoteredza zvakare zvakaomesesa, saka mutengo wacho wakakwira.
Bhatiri reLithium iron phosphate: mutengo wezvinhu zvakagadzirwa wakaderera, maitiro ekugadzira ari nyore, uye mutengo wese une zvakanakira. Semuenzaniso, mumotokari itsva dzemagetsi, mhando dzakashongedzerwa nemabhatiri e-lithium iron phosphate dzinowanzo kuve dzakaderera pamutengo.
Mhedziso
Kusarudzwa kwebhatiri kunonyanya kuenderana nezvinodiwa pakushandisa. Kana simba rakawanda uye hupenyu hwebhatiri hurefu zvichidikanwa, mabhatiri e-ternary lithium anogona kunge ari sarudzo iri nani; kana kuchengetedzeka, kugara kwenguva refu uye hupenyu hurefu zviri izvo zvinonyanya kukosheswa, mabhatiri e-lithium iron phosphate ndiwo akakodzera.
Heltec Energy ndiyo kambani yaunovimba nayo mubhatirikugadzira. Nekutarisa kwedu kusingapereri pakutsvaga nekuvandudza, pamwe chete nemidziyo yedu yakawanda yemabhatiri, tinopa mhinduro dzese kuti tisangane nezvinodiwa zviri kuchinja zveindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa, uye hukama hwakasimba nevatengi zvinoita kuti tive sarudzo yakanaka kune vagadziri vemabhatiri nevatengesi pasi rese.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
