Yize kunezindaba zamabhethri esimo esiqinile muva nje, kusenezinkinga eziningi ezisazoxazululwa kumabhethri esimo esiqinile. Luselude ukhalo okusamele luhanjwe ngokukhiqizwa kwayo ngobuningi bezentengiselwano nokusebenzisa ezimotweni ezintsha ezisebenza ngamandla. 48VAGV lithium battery.jpg

Imvamisa yamanje yamabhethri amandla kusengamabhethri e-ternary kanye namabhethri e-lithium iron phosphate. Esikhathini esidlule, amabhethri e-lithium iron phosphate abelokhu ekhula ngamandla, futhi ziya ngokuya zikhula izimoto zabagibeli ezinamandla amasha zisuka kumabhethri e-ternary zaya kumabhethri e-lithium iron phosphate.

Lesi sihloko sibheka umehluko phakathi kwamabhethri e-ternary namabhethri e-lithium iron phosphate emibonweni emihlanu: ukuphepha, ukuminyana kwamandla, ukukhishwa kwezinga lokushisa eliphansi, ukusebenza kahle kokushaja, nempilo yomjikelezo.

1. Security

Ibhethri ye-blade ibhethri ye-lithium iron phosphate. Ibhethri le-blade lifakazele ukuthi lingakwazi ukuphumelela ukuhlolwa kwe-acupuncture, kuyilapho ibhethri ye-ternary ayikwazi. Ngakho-ke, ibhethri ye-lithium iron phosphate iyibhethri eliphephile kunebhethri le-ternary.

Ngaphezu kwalokho, ukuzinza okushisayo kwe-lithium iron phosphate cathode impahla ngokwayo kungcono kakhulu kune-ternary lithium. Inokuqina okuphezulu kakhulu phakathi kwama-degrees Celsius angama-500. Ukushisa okushisayo kwenzeka uma kudlula ama-degree Celsius angama-800. Ngaphezu kwalokho, ngisho noma kwenzeka ukubaleka okushisayo, Ukukhishwa kokushisa kwebhethri ye-lithium iron phosphate nakho kuhamba kancane, futhi ngeke kukhulule umoya-mpilo lapho kubola, kunciphisa ingozi yomlilo.

Ngokuphambene, amabhethri e-lithium e-ternary aqala ukuncibilika cishe ku-300 degrees Celsius. Ekushiseni okuzenzakalelayo kwezimoto zamandla amasha, amamodeli ebhethri ye-lithium athatha ingxenye enkulu.

2. Amandla kagesi

Ngokolwazi olusesidlangalaleni oluvela ezinkampanini zasekhaya, kuvamile ukuthi amabhethri e-ternary asezingeni eliphezulu abe nokuminyana kwamandla okukodwa okungu-250Wh/kg noma ngaphezulu, kuyilapho ibhethri lasekhaya le-lithium iron phosphate linamandla okuminyana okungaba ngu-180Wh/kg.

Kusukela kuleli phuzu lokubuka, ibhethri le-ternary linomthamo wamandla ongcono kunebhethri ye-lithium iron phosphate.

Nakuba ibhethri ye-blade ethuthukiswe yi-BYD ithuthukise ukusebenza kahle kokuhlanganiswa kabusha kweseli yebhethri, futhi ukuminyana kwamandla evolumu kukhuphuke ngamaphesenti angama-50, lolu wushintsho lwesakhiwo. Ukuminyana kwamandla ngamanye ebhethri ye-lithium iron phosphate akukhulanga.

3. Ukukhishwa kwezinga lokushisa eliphansi

Uma kuqhathaniswa, ku-minus 20 degrees Celsius, amabhethri e-lithium e-ternary anezinzuzo ezisobala ngaphezu kwamabhethri e-lithium iron phosphate.

4. Ukushaja kahle

Njengamanje, indlela yokushaja ejwayeleke kakhulu emakethe ukushaja kwamanje kanye nokushaja okungaguquki. Ngokuvamile isetshenziswa ekuqaleni kokushaja. Ukushaja okuqhubekayo kwamanje kusetshenziswa kuqala. Ngalesi sikhathi, yamanje inkulu futhi ukusebenza kahle kokushaja kuphakeme kakhulu. Lapho i-voltage ifinyelela inani elithile, izokwehla. I-current ishintshwa ibe ukushajwa kwe-voltage njalo, ukuze ibhethri likwazi ukushajwa ngokugcwele.

Kule nqubo, isilinganiso somthamo wokushaja wamanje ongashintshi kumthamo webhethri eliphelele libizwa ngokuthi isilinganiso samanje esingaguquki, okuyinani eliyinhloko lokulinganisa ukusebenza kahle kokushaja kweqembu lamabhethri ngesikhathi sokushaja. Imvamisa, lapho iphesenti lilikhulu, kulapho ugesi ushajwa kakhulu esigabeni samanje esingaguquki. Uma iphezulu, kulapho izinga lokushaja kwebhethri libonakala liphezulu khona.

Isilinganiso senani lokushajwa kanye nokuphumayo kwamanje nenani lebhethri inani lokushajwa nokukhipha. Kungabonakala kudatha yokuthi lapho ibhethri ye-lithium ye-ternary kanye nebhethri ye-lithium iron phosphate ishajwa ngenani elingaphansi kwezikhathi eziyishumi, awukho umehluko obalulekile esilinganisweni samanje esiqhubekayo. Isilinganiso samanje esiqhubekayo sebhethri ye-iron-lithium sincishiswa ngokushesha, futhi ukusebenza kahle kokushaja kuncipha ngokushesha. Kuyabonakala ukuthi ibhethri le-ternary lithium linenzuzo enkulu ngokusebenza kahle kokushaja.

5. Impilo yomjikelezo

Uma umthamo osele ungama-80% womthamo wokuqala njengokuphela kokuhlolwa, ukuhlolwa kwelabhorethri yamanje yebhethri ye-lithium iron phosphate inokuphila komjikelezo izikhathi ezingaphezu kuka-3,500, kanti ezinye zifinyelele izikhathi ezingu-5,000.

Impilo yomjikelezo wokuhlola webhethri le-ternary lithium cishe izikhathi ezingama-2500. Ephuzwini lempilo yomjikelezo, ibhethri ye-lithium iron phosphate inempilo yangempela ende kakhulu kunebhethri ye-ternary lithium.

Ngaphansi kwenani elifanayo lemijikelezo, umthamo osele webhethri le-lithium iron phosphate ungaphezu nje kwebhethri le-ternary lithium. I-ternary lithium battery ijikeleziswa izikhathi ezingu-3900 kanti umthamo osele ungama-66%. Ibhethri ye-lithium iron phosphate ijikeleziswa izikhathi ezingu-5000 kanti umthamo osele ungama-84%. Ibhethri ye-lithium iron phosphate inezinzuzo ezisobala.

Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi i-lithium iron phosphate inezinzuzo ezisobala mayelana nokuphepha nokuphila komjikelezo; amabhethri e-ternary aphakeme ngobuningi bamandla, akhipha izinga lokushisa eliphansi, nokusebenza kahle kokushaja.

Yiqiniso, akusho ukuthi yimaphi amabhethri amabili angcono, ngoba wonke anezimo zawo zokusebenza ezinhle kakhulu.
