Nhanganyaya:
Ternary lithium mabhatiri uyelithium iron phosphate mabhatirindiyo miviri mikuru yemabhatiri e-lithium parizvino anoshandiswa zvakanyanya mumotokari dzemagetsi, masisitimu ekuchengetedza simba uye zvimwe zvigadzirwa zvemagetsi. Asi wakanzwisisa here maitiro avo uye kusiyana kwavo? Kuumbwa kwavo kwemakemikari, maitiro ekuita uye minda yekushandisa zvakasiyana zvakanyanya. Ngatidzidze zvakawanda nezvavo neHeltec.
Kuumbwa kwezvinhu:
Ternary lithium bhatiri: Iyo yakanaka electrode zvinhu zvinowanzoita nickel cobalt manganese oxide (NCM) kana nickel cobalt aluminium oxide (NCA), iyo inoumbwa nickel, cobalt, manganese kana nickel, cobalt, aruminiyamu uye zvimwe simbi zvinhu oxides, uye iyo yakaipa. electrode inowanzoita graphite. Pakati pavo, chiyero che nickel, cobalt, manganese (kana aluminium) inogona kugadziriswa maererano nezvinodiwa chaizvo.
Lithium iron phosphate bhatiri: lithium iron phosphate (LiFePO₄) inoshandiswa seyakanaka electrode zvinhu, uye graphite inoshandiswawo kune iyo yakaipa electrode. Kemikari yaro yakagadzikana, uye haina simbi inorema uye isingawanzo simbi, iyo inonyanya kushamwaridzana nenharaunda.
Charge uye discharge performance:
Ternary lithium bhatiri: kukurumidza kubhadharisa uye kuburitsa kumhanya, inogona kuenderana neyakakwira ikozvino kuchaja uye kuburitsa, inokodzera midziyo uye mamiriro ane zvakakwirira zvinodikanwa zvekuchaja kumhanya, senge mota dzemagetsi dzinotsigira kukurumidza kuchaja. Munzvimbo yakadzika tembiricha, kubhadharisa kwayo uye kuburitsa kuita kwayo kunenge kwakanaka, uye kurasikirwa kwesimba kudiki.
Lithium iron phosphate bhatiri: inononoka kuchaja uye yekumhanyisa kumhanya, asi yakagadzika kutenderera kubhadharisa uye kuita kwekuburitsa. Inogona kutsigira kubhadharisa kwakakwira uye inogona kubhadhariswa zvizere muawa ye1 nekukurumidza, asi kubhadharisa uye kuburitsa kunyatsoita kunowanzo kutenderera 80%, iyo yakadzikira zvishoma pane iyo yeternary lithium bhatiri. Pasi pemamiriro ekunze ekupisa, kushanda kwayo kunoderera zvakanyanya, uye chiyero chekuchengetedza bhatiri chinogona kunge chiri 50% -60%.
Energy density:
Ternary lithium bhatiri: Iyo simba density yakakwira, kazhinji inosvika kupfuura 200Wh/kg, uye zvimwe zvigadzirwa zvepamberi zvinogona kudarika 260Wh/kg. Izvi zvinobvumira ternary lithium mabhatiri kuchengetedza simba rakawanda pavhoriyamu imwechete kana huremu, ichipa kureba kwekutyaira kwemidziyo, senge mumotokari dzemagetsi, dzinogona kutsigira mota kufamba nzendo refu.
Lithium iron phosphate bhatiri: Iyo simba density yakadzikira, kazhinji kutenderera 110-150Wh/kg. Naizvozvo, kuti uwane iyo yakafanana yekutyaira senge ternary lithium mabhatiri, lithium iron phosphate mabhatiri angangoda vhoriyamu yakakura kana huremu.
Cycle life:
Ternary lithium bhatiri: Hupenyu hwekutenderera ipfupi, ine theoretical kutenderera nhamba yenguva dzinenge zviuru zviviri. Mukushandisa chaiko, huwandu hwacho hunogona kunge hwakaora kusvika pamakumi matanhatu muzana mushure me1,000 kutenderera. Kusashandisa zvisina kunaka, sekunge kuwandisa kana kuburitsa, uye kushandiswa munzvimbo dzakanyanya tembiricha, kunomhanyisa kuora kwebhatiri.
Lithium iron phosphate bhatiri: Hupenyu hurefu hwekutenderera, huine anopfuura zviuru zvitatu nemazana mashanu ekuchajisa uye kuburitsa mabhatiri, uye mamwe mabhatiri emhando yepamusoro anogona kutosvika kanopfuura ka5,000, izvo zvakaenzana nemakore anopfuura gumi ekushandiswa. Iyo ine yakanaka lattice kugadzikana, uye kuiswa uye kubviswa kwelithium ion hakuna mhedzisiro pane lattice, uye ine yakanaka reversibility.
Safety:
Ternary lithium bhatiri: kuderera kwekushisa kwekushisa, nyore kukonzera kupisa kwekushisa pasi pekushisa kwepamusoro, kuwandisa, pfupi pfupi uye mamwe mamiriro ezvinhu, zvichiita kuti pave nengozi yakawanda yekupisa kana kunyange kuputika. Nekudaro, nekufambira mberi kwetekinoroji uye kusimbiswa kwemaitiro ekuchengetedza, sekushandiswa kweakanyanya bhatiri manejimendi masisitimu uye optimization yebhatiri chimiro, kuchengetedzeka kwayo kunogara kuchivandudza.
Lithium iron phosphate bhatiri: yakanaka yekupisa kugadzikana, iyo yakanaka electrode zvinhu hazvisi nyore kuburitsa okisijeni pakupisa kwakanyanya, uye haizotanga kuora kusvika 700-800 ℃, uye haizobudise mamorekuru eokisijeni kana yakatarisana nemhedzisiro, puncture, pfupi dunhu uye mamwe mamiriro ezvinhu, uye haawanzo kupiswa nechisimba, nepamusoro pekuchengetedza kushanda.
Mutengo:
Ternary lithium bhatiri: nekuti iyo yakanaka electrode zvinhu ine inodhura simbi zvinhu senge nickel necobalt, uye zvinodiwa zvekugadzira zvakakwirira, uye zvinodiwa kwezvakatipoteredza zvakare zvakaomarara, saka mutengo wakakwira.
Lithium iron phosphate bhatiri: mutengo wezvakagadzirwa wakaderera, maitiro ekugadzira ari nyore, uye mutengo wakazara une zvimwe zvakanakira. Semuenzaniso, mumotokari itsva dzemagetsi, mhando dzakashongedzerwa ne lithium iron phosphate mabhatiri anowanzo kuderera mumutengo.
Mhedziso
Kusarudzwa kwebhatiri kunoenderana zvakanyanya nezvinodiwa zvekushandisa. Kana yakakwira simba density uye hurefu hwebhatiri hupenyu hunodiwa, ternary lithium mabhatiri anogona kunge ari sarudzo iri nani; kana kuchengetedzwa, kusimba uye hupenyu hurefu zviri izvo zvinonyanya kukosha, lithium iron phosphate mabhatiri anonyanya kukodzera.
Heltec Energy ndiye shamwari yako yaunovimba nayobhatiri packkugadzira. Nekutarisa kwedu kusingagumi pakutsvaga nekusimudzira, pamwe nehupamhi hwemabhatiri ezvishandiso zvedu, tinopa mhinduro imwe chete yekusangana nezvinodiwa neindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa, uye kudyidzana kwakasimba kwevatengi kunotiita isu kuenda-kune sarudzo yevagadziri vebhatiri pack uye vatengesi pasi rese.
Kana uine chero mibvunzo kana uchida kudzidza zvakawanda, ndapota usazezasvika kwatiri.
