Cima umyalelo

Ngethamsanqa, ngenxa yomsebenzi wam wangaphambili, ndisuse amakhulu eebhetri ezandleni zam, kuquka iibhetri ze-lithium-ion iron phosphate, iibhetri ze-terpolymer lithium, iibhetri eziguquguqukayo zokupakisha kunye neebhetri zecylindrical. Namhlanje ndiza kuqhaqha kwaye ndikubonise isimo sepaneli yangaphakathi yebhetri.

Njengoko i-lithium ion ingena, i-graphite anode ngokuthe ngcembe ijika ibe yigolide, kodwa kunzima ukubona i-anode ngokutshintsha kombala. Sidla ngokugweba indlela yokutshaja kunye nokukhupha kunye nomgangatho webhetri ngokuqhawula ibhetri kunye nokujonga imeko yojongano lwe-electrode engalunganga.

I-SOC = 7%, kwakukho amaqhekeza phakathi kwe-electrode, kwaye i-electrode ayizange itshintshe umbala.

Xa i-SOC = 14%, amasuntswana aphakathi kwe-electrode angabonwa. Ukutshintsha kwebala kancinci.

I-SOC yi-26% encinci eluhlaza okwesibhakabhaka.

I-SOC=53.9%, ijika ibe luhlaza, amaqamza ayabonakala.

Ubume bokuhlawulisa = 70.0%, ukusuka kwimfusa emnyama ukuya ebomvu, indawo ebonakalayo engahlawulwanga emnyama. Akukho mvula ye-lithium ion yafunyanwa.

Intlawulo epheleleyo = 81.5%, ijika kwigolide, indawo ebonakalayo emnyama engahlawulwanga. Unokubona ukuvela kwe-lithium emhlophe.

Njengoko kunokubonwa kumfanekiso ongentla, xa imeko ehlawulisiweyo ingaphantsi kwama-50%, i-electrode state ayitshintshi kakhulu. Utshintsho kwi-electrode lunokubonwa ngaphezu kwe-50%. Njengoko kubonisiwe kuMfanekiso 4, inani elikhulu lamaqamza linokufumaneka malunga ne-3.6V. Inokuthi ithathelwe ingqalelo ukuba kukho utshintsho oluphawulekayo phakathi koMfanekiso 5 kunye noMfanekiso 6. Ilizwe elihlawulisiweyo litshintsha kuphela nge-10%, kodwa i-electrode state ihluke ngokupheleleyo.

Imeko ye-Electrode xa ibhetri SOC=100%. Inxalenye emhlophe yi-lithium.

Emva kokususa inxalenye emhlophe, umphezulu wepali esezantsi ayiguquli igolide, ebonisa ukuba i-lithium ion ayifakwanga kwizinto eziphathekayo ze-electrode. Ngamafutshane, izinto ezintle kule nxalenye yezinto eziphathekayo zivimbela i-lithium ion ukuba ifake, ngoko ke i-lithium ion iyancipha ukuya phezulu. Kucingelwa ukuba i-binders (i-CMC kunye ne-SBR) isasazwa ngokungalingani kwi-electrode surface kwaye ifakwe ngekhabhoni kwizinto ze-anode, ezikhokelela ekufakweni kwe-lithium ion.

Xa i-state ehlawuliswayo i-100%, amaninzi amabala amnyama ayindawo engahlawulwanga. Kukho amabala amaninzi amnyama kwibhetri, isizathu esibalulekileyo somthamo ophantsi webhetri. Izinto ezibalulekileyo ezibangela amabala amnyama kukufana kwe-slurry, ukuchaneka kokulawula ukuxinana kwendawo yokugubungela, ukulawulwa koxinzelelo lokujikeleza kunye nokusekwa kwegesi.
