Susa umyalelo

Ngenhlanhla, ngenxa yomsebenzi wami wangaphambilini, ngisuse amakhulu amabhethri ezandleni zami, okuhlanganisa amabhethri e-lithium-ion iron phosphate, amabhethri e-lithium e-terpolymer, amabhethri ephakethe aguquguqukayo namabhethri angama-cylindrical. Namuhla ngizokuqaqa futhi ngikubonise isimo sephaneli yangaphakathi yebhethri.

Njengoba i-lithium ion ingena, i-graphite anode kancane kancane iphenduka igolide, kodwa kunzima ukubona i-anode ngokushintsha kombala. Sivamise ukwahlulela indlela yokushaja nokukhipha kanye nekhwalithi yebhethri ngokuqaqa ibhethri futhi sibheke isimo sokusebenzisana se-electrode eyinegethivu.

I-SOC = 7%, kwakukhona izinhlayiya phakathi nendawo ye-electrode, futhi i-electrode ayizange ishintshe umbala.

Lapho i-SOC = 14%, izinhlayiya eziphakathi kwe-electrode zingabonakala. Ukushintsha umbala kancane.

I-SOC ingu-26% eluhlaza okwesibhakabhaka kancane.

I-SOC=53.9%, iphenduka ibe luhlaza okwesibhakabhaka, amabhamuza ayabonakala.

Isimo sokushaja =70.0%, ukusuka kokunsomi okumnyama kuya kokubomvu, indawo ebonakalayo engashajiwe emnyama. Ayikho imvula ye-lithium ion etholakele.

Ukushaja okugcwele =81.5%, kuphendukela egolide, indawo emnyama ebonakalayo engashajiwe. Ungabona ukuvela kwe-lithium emhlophe.

Njengoba kungabonakala esithombeni esingenhla, lapho isimo esikhokhisiwe singaphansi kuka-50%, isimo se-electrode asishintshi kakhulu. Izinguquko ku-electrode zingabonwa ngaphezu kwama-50%. Njengoba kukhonjisiwe kuMfanekiso 4, inani elikhulu lamabhamuza lingatholakala cishe ku-3.6V. Kungacatshangwa ukuthi kukhona ushintsho olubalulekile phakathi koMfanekiso 5 kanye noMfanekiso 6. Isimo esikhokhisiwe sishintsha ngo-10% kuphela, kodwa isimo se-electrode sihluke ngokuphelele.

Isimo se-Electrode lapho ibhethri SOC=100%. Ingxenye emhlophe yi-lithium.

Ngemva kokukhipha ingxenye emhlophe, ingaphezulu lesigxobo esingaphansi aliguquki igolide, okubonisa ukuthi i-lithium ion ayifakiwe ku-electrode material positive. Ngamafuphi, izinto ezinhle kule ngxenye yezinto ezibonakalayo zivimbela i-lithium ion ukuthi ingashumeki, ngakho-ke ama-ion e-lithium akhuphukela phezulu. Kucatshangelwa ukuthi izibophezelo (i-CMC ne-SBR) zisakazwa ngokungalingani endaweni ye-electrode futhi zimbozwe ngekhabhoni endaweni ye-anode, okuholela ekufakweni kwe-lithium ion.

Uma isimo esikhokhisiwe singu-100%, iningi lamabala amnyama yizindawo ezingakhokhisiwe. Kunamabala amaningi amnyama ebhethrini, okuyisizathu esibalulekile somthamo ophansi webhethri. Izici ezibalulekile ezibangela amachashazi amnyama ukufana kwe-slurry, ukunemba kokulawula ukuminyana kwendawo enamathelayo, ukulawulwa kokuqina kokusonteka kanye nokwakheka kwegesi.
