Imibuzo Evame Ukubuzwa

Ibhethri ye-lithium-ion ibhethri elishajekayo, elisebenza ngokuhamba kwama-ion e-lithium phakathi kwama-electrode aqondile noma angalungile. Ngesikhathi sokushaja, i-Li + ifakwe ku-electrode enhle, ishumeke ku-electrode engalungile ngokusebenzisa i-electrolyte, futhi i-electrode engalungile isesimweni esicebile i-lithium; ngesikhathi sokukhishwa, okuphambene kuyiqiniso.

Ibhethri ye-lithium-ion isebenzisa i-lithium iron phosphate njengento esebenzayo ye-electrode, siyibiza ngokuthi ibhethri ye-lithium iron phosphate.

Ibhethri le-lithium iron phosphate(LiFePO4/LFP) linikeza izinzuzo eziningi uma liqhathaniswa nelinye ibhethri le-lithium nebhethri le-asidi eholayo.Isikhathi eside sokuphila,ukugcinwa kweqanda,kuphephe ngokwedlulele,okungasindi,ukushaja okusheshayo,njll.Ibhethri le-lithium iron phosphate libiza kakhulu imakethe.

1. IPHEPHILE:Ibhondi ye-PO ku-lithium iron phosphate crystal izinzile kakhulu futhi kunzima ukubola. Ngisho nasezingeni eliphezulu lokushisa noma ukushajwa ngokweqile, ngeke liwe futhi likhiqize ukushisa noma lenze izinto eziqinile ze-oxidizing, ngakho linokuphepha okuhle.
2. Isikhathi sokuphila eside: Umjikelezo wokuphila wamabhethri e-lead-acid cishe izikhathi ezingu-300, kuyilapho umjikelezo wempilo wamabhethri wamandla we-lithium iron phosphate ungaphezu kwezikhathi ezingu-3,500, impilo yasetiyetha cishe iminyaka eyi-10.
3. Ukusebenza kahle ekushiseni okuphezulu: Ububanzi bokushisa obusebenzayo bungu-20 ℃ kuya ku-+75 ℃, nokumelana nokushisa okuphezulu, ukuphakama kokushisa kagesi kwe-lithium iron phosphate kungafinyelela ku-350 ℃-500 ℃, ephakeme kakhulu kune-lithium manganate noma i-lithium cobaltate. 200℃.
4. Umthamo omkhulu Iqhathaniswa nebhethri le-lead acid, i-LifePO4 inomthamo omkhulu kunamabhethri ajwayelekile.
5. Ayikho inkumbulo: Kungakhathaliseki ukuthi ibhethri ye-lithium iron phosphate ikusiphi isimo, ingasetshenziswa nganoma yisiphi isikhathi, akukho nkumbulo, okungadingekile ukuyikhipha ngaphambi kokushaja.
6. Isisindo esilula :Uma kuqhathaniswa nebhethri le-asidi yomthofu elinomthamo ofanayo, IVOLUME yebhethri le-lithium iron phosphate ingu-2/3 webhethri le-lead-asidi, futhi isisindo singu-1/3 webhethri le-asidi yomthofu.
7. Imvelo enobungani: Azikho izinsimbi ezisindayo nezinsimbi ezingavamile ngaphakathi, ezingenabo ubuthi, akukho ukungcola, nemithetho ye-European ROHS, ibhethri le-lithium iron phosphate ngokuvamile libhekwa njengelilungele imvelo.
8. Ukukhishwa okusheshayo kwamanje: Ibhethri le-lithium iron phosphate lingashajwa ngokushesha futhi likhishwe ngamandla aphezulu angu-2C. Ngaphansi kweshaja ekhethekile, ibhethri ingashajwa ngokugcwele phakathi kwemizuzu engu-40 yokushajwa okungu-1.5C, futhi isimanjemanje esiqalayo singafinyelela ku-2C, kuyilapho ibhethri le-asidi yomthofu ingenakho lokhu kusebenza manje.

Ibhethri ye-LiFePO4 iwuhlobo oluphephe kunazo zonke lwebhethri ye-lithium. Ubuchwepheshe obusekelwe ku-Phosphate bunokuqina okushisayo namakhemikhali aphezulu okunikeza izici ezingcono zokuphepha kunalezo zobuchwepheshe be-Lithium-ion ezenziwe ngezinye izinto ze-cathode. Amaseli e-lithium phosphate awashi uma kwenzeka ephathwa kabi ngesikhathi eshajwa noma ekhishwa, azinzile ngaphansi kwezimo zokushajwa ngokweqile noma zokujikeleza okufushane futhi angakwazi ukumelana namazinga okushisa aphezulu. I-LifePO4 inezinga lokushisa eliphakeme kakhulu le-thermal elibalekayo uma liqhathaniswa nezinye izinhlobo cishe elingama-270℃ njengoba liqhathaniswa neliphansi njenge-150℃. I-LiFePO4 iphinde ibe namandla amakhemikhali uma iqhathaniswa nezinye izinhlobo.

I-BMS imfushane kokuthi Uhlelo Lokuphatha Ibhethri. I-BMS ingakwazi ukuqapha isimo sebhethri ngesikhathi sangempela, ilawule amabhethri angaphakathi ebhodini, ithuthukise ukusebenza kahle kwebhethri, ivikele ukushajwa kwebhethri nokuphuma ngokweqile, ithuthukise impilo yebhethri.

Umsebenzi oyinhloko we-BMS ukuqoqa idatha efana ne-voltage, izinga lokushisa, amandla amanje, kanye nokumelana nesistimu yebhethri lamandla, bese uhlaziya isimo sedatha nendawo yokusetshenziswa kwebhethri, futhi uqaphe futhi ulawule inqubo yokushaja nokukhipha yesistimu yebhethri. Ngokomsebenzi, singahlukanisa imisebenzi eyinhloko ye-BMS ekuhlaziyeni isimo sebhethri, ukuvikelwa kokuphepha kwebhethri, ukuphathwa kwamandla ebhethri, ukuxhumana nokuxilongwa kwephutha, njll.

Ingabe ibhethri ye-Lithium ingafakwa kunoma iyiphi indawo?
Yebo. Njengoba kungekho uketshezi kubhethri ye-lithium, futhi ikhemistri iqinile, ibhethri lingafakwa kunoma iyiphi indlela.
