Yintoni eQinisekisa ngokwenene umgangatho wokugquma kwimveliso yeebhetri zeLithium?

Kwimveliso yebhetri ye-lithium-ion, ukugquma akuyonto nje yenkqubo - yinto ebalulekileyo ebumba ukusebenza kwebhetri, ukuhambelana, kunye nokusebenza kakuhle kwemveliso. Ukusuka kwiibhetri zamandla e-EV ukuya kwiinkqubo zokugcina amandla ezinkulu, abavelisi baphantsi koxinzelelo olukhulu lokufikelela ngokuchanekileyo okuphezulu, ukuveliswa ngokukhawuleza, kunye namazinga aphantsi eziphene.

Nangona kunjalo, imingeni eqhelekileyo isenzima ukuyisombulula:

• Ukwaleka okungalinganiyo kukhokelela kumandla angazinzile kunye nobomi bomjikelo obunciphileyo

• Ukuvuza kwe-slurry kunye nokungahambelani koxinano kuchaphazela umgangatho we-electrode

• Isantya sokwaleka semveli 80–100 m/ngomzuzu ukunciphisa imveliso enkulu

• Ukungazinzi kokomisa kubangela iziphene ezifana nokugoba komphetho kunye nokuqhekeka

Njengoko imveliso ifikelela kumanqanaba amakhulu emveliso, le micimbi ayiseyiyo ingxaki ezimeleyo - ichaphazela ngokuthe ngqo isivuno, iindleko, kunye nokukhuphisana.

Ukujongana nale mingeni, ubuchwepheshe obuphambili bokugquma buya bufuneka. Ngokukodwa, iinkqubo zokugquma ezikhawulezayo eziphindwe kabini ziyasetyenziswa ngakumbi kwiindlela zanamhlanje zokuvelisa iibhetri.

Xa kuthelekiswa neenkqubo eziqhelekileyo, ezi nkqubo zinokwenza oku kulandelayo:

• Ukuphucula ukusebenza kakuhle kwemveliso ngokubanzi 60–80%

• Fumana isantya sokugquma ukuya kuthi ga kwi 160 m/ngomzuzu

• Gcina ukuchaneka okuphezulu ngolawulo lokuphambuka ngaphakathi ±1.0%

• Qinisekisa ulawulo oluzinzileyo loxinzelelo ngaphakathi ±2N

• Ukubonelela ngokusebenza okomileyo rhoqo ngokuguquguquka komoya ≤ ±2%

Okubaluleke ngakumbi, iinkqubo zokugquma ezidityanisiweyo zidibanisa ukugquma, ukomisa, kunye nokujika zibe yinkqubo eqhubekayo, ezenzekelayo - kunciphisa kakhulu ukungenelela ngesandla kunye nokuphucula uzinzo lwemveliso.

Kwizicelo zokwenyani, abavelisi abaphucula ukuya kwiinkqubo zokugquma ezikumgangatho wesibini baxele ukuba ukusebenza kakuhle kuphucukile ngaphezu 30%, kunye nokunciphisa amazinga eziphene kunye nenkunkuma yezinto eziphathekayo. Olu phuculo lubaluleke kakhulu kwiindawo zemveliso ezinomthamo omkhulu apho notshintsho oluncinci lunokukhokelela kwilahleko enkulu.

Kwabavelisi abafuna izisombululo ezithembekileyo, iitekhnoloji zokugquma ezidityanisiweyo zenziwe ngababoneleli bezixhobo abanamava ezifana Pengjin zisetyenziswa kakhulu kwiiprojekthi zokugcina iibhetri zamandla kunye nezokugcina amandla. Ezi nkqubo zenzelwe ukuphatha izinto ezibhityileyo kakhulu (umz., Ifoyile yobhedu eyi-4μm kunye nefoyile ye-aluminiyam eyi-6μm) ngelixa igcina ukusebenza okukhawulezayo nokuchaneka okuphezulu.

Ngaphaya kwezixhobo ezizimeleyo, oomatshini bokugquma banamhlanje badityaniswa ngakumbi kwimigca yemveliso epheleleyo, besebenza kunye neenkqubo zokubuyisela i-NMP, ukuqengqeleka, kunye neenkqubo zokuqhawula ukwenza inkqubo epheleleyo yokuvelisa ekrelekrele.

Njengoko ishishini leebhetri ze-lithium liqhubeka nokutshintsha, iteknoloji yokugquma ayisekho nje malunga nokusebenzisa izixhobo - imalunga nokwenza imveliso ibe nokukhula, ikumgangatho ophezulu, kwaye ingabizi kakhulu.

Ukuba uceba umgca omtsha wokuvelisa ibhetri okanye ulungisa osele ukho, ukuqonda indlela iinkqubo zokugquma eziphambili eziphucula ngayo ukusebenza kakuhle kunye nokuhambelana kunokwenza umahluko olinganisekayo kwiziphumo zakho.
