I-lithium iron phosphate battery nayo ibhethri ye-lithium, empeleni iyigatsha lebhethri le-lithium ion, iqukethe i-lithium manganese oxide, i-lithium cobalt oxide ne-ternary lithium battery. Ukusebenza kwayo kufanelekile ikakhulukazi kuzicelo zamandla. Ibizwa nangokuthi ibhethri lamandla e-lithium iron phosphate, elibizwa nangokuthi i-lithium iron battery. Ngakho-ke, inzuzo yamabhethri e-lithium iron phosphate ikakhulukazi ibhekisa ekuphepheni kwabo nasekuzinzileni uma kuqhathaniswa namanye amabhethri kuzicelo zamandla. Kokunye, kuzoba nezinzuzo ngaphezu kwamabhethri e-lithium we-ternary namabhethri e-lead-acid.

Okokuqala, amabhethri e-lithium iron phosphate anokusebenza okungcono kwezinga lokushisa eliphezulu futhi angamelana namazinga okushisa asuka ku-350 ° C kuye ku-500 ° C, kuyilapho i-lithium manganate / cobalt oxide imvamisa icishe ibe ngu-200 ° C. Okokusebenza kwebhethri le-lithium elithuthukisiwe nakho kuzoba ku-200 ° C.

Okwesibili, amabhethri e-lithium iron phosphate anempilo yomjikelezo omude kunamabhethri e-lead-acid namabhethri e-lithium we-ternary. “Impilo yomjikelezo” yebhethri ye-lead-acid icishe ibe izikhathi ezingama-300 kuphela, futhi ubukhulu bube izikhathi ezingama-500; ngenkathi impilo yemfundiso yebhethri ye-lithium yebhethri ingafinyelela izikhathi ezingama-2000, kepha uma isetshenziswa cishe izikhathi eziyi-1000, umthamo uzokwehla uye kuma-60%. Futhi impilo yangempela yebhethri ye-lithium iron phosphate lithium ibhekene nezikhathi ezingama-2000. Ngalesi sikhathi, kusekhona amandla angama-95%, futhi impilo yomjikelezo wayo ongafinyelela ngaphezu kwezikhathi ezingama-3000.

Okwesithathu, kunezinzuzo eziningi uma ziqhathaniswa namabhethri e-lead-acid:

1. Umthamo omkhulu. Iseli le-3.2V lingenziwa i-5Ah ~ 1000 Ah (1 Ah = 1000m Ah), futhi iseli le-2V yebhethri elihola-acid livame ukuba yi-100Ah ~ 150 Ah.

2. Isisindo esincane. Umthamo webhethri le-lithium iron phosphate lomthamo ofanayo ngu-2/3 wevolumu yebhethri yomthofu-asidi, futhi isisindo singu-1/3 walokugcina.

3. Amandla okushaja okusheshayo. Ukuqala kwamanje kwebhethri yensimbi ye-lithium phosphate kungafinyelela ku-2C, engabona ukushaja okuphezulu; ukufunwa kwamanje kwebhethri ye-lead-acid imvamisa iphakathi kuka-0.1C no-0.2C, futhi ukushaja okusheshayo akunakufinyelelwa.

4. Ukuvikelwa kwemvelo. Amabhethri e-lead-acid aqukethe izinsimbi eziningi ezisindayo, ezizokhiqiza uketshezi lwemfucuza. Amabhethri e-lithium iron phosphate aqukethe izinsimbi ezisindayo, futhi akukho ukungcola ekukhiqizeni nasekusetshenzisweni.

5. Ukusebenza kwezindleko eziphezulu. Yize amabhethri e-lead-acid eshibhile kunezinto zokwakha, izindleko zokuthenga ziphansi kunamabhethri e-lithium iron phosphate, kepha maqondana nempilo yesevisi nokugcinwa njalo, awabizi njengamabhethri e-lithium iron phosphate. Imiphumela esebenzayo yesicelo ikhombisa ukuthi ukusebenza kwezindleko zamabhethri e-lithium iron phosphate kungaphezu kwezikhathi ezi-4 zamabhethri e-lead-acid.

Yize uhla lwesicelo samabhethri e-lithium iron phosphate lubonakala kakhulu esiqondisweni samandla, ngombono lingabuye linwetshelwe emikhakheni engaphezulu, kungenzeka ukuthi lenyuse izinga lokukhishwa nezinye izici, futhi lifake izinkambu zokufaka zendabuko zezinye izinhlobo Amabhethri e-lithium-ion.
