Yini Enquma Ngempela Ikhwalithi Yokumboza Ekukhiqizweni Kwebhethri Le-Lithium?

Ekukhiqizweni kwebhethri le-lithium-ion, ukugqoka kungaphezu nje kwesinyathelo senqubo - kuyisici esinqumayo esibumba ukusebenza kwebhethri, ukuhambisana, kanye nokusebenza kahle kokukhiqiza. Kusukela kumabhethri kagesi e-EV kuya ezinhlelweni zokugcina amandla ezinkulu, abakhiqizi bangaphansi kwengcindezi ekhulayo yokufinyelela ukunemba okuphezulu, ukukhishwa okusheshayo, kanye namazinga aphansi okukhubazeka.

Noma kunjalo, izinselele ezivamile zisalokhu kunzima ukuzinqoba:

• Ukumbozwa okungalingani kuholela ekungazinzileni kwamandla kanye nokuphila komjikelezo okuncishisiwe

• Ukuvuza kwe-slurry kanye nokungalingani kobuningi kuthinta ikhwalithi ye-electrode

• Isivinini sokumboza sendabuko 80–100 m/min ukunciphisa ukukhiqizwa okukhulu

• Ukungazinzile komile kubangela ukukhubazeka okufana nokugoba komphetho kanye nokuqhekeka

Njengoba ukukhiqizwa kufinyelela emazingeni amakhulu ezimboni, lezi zinkinga azisezona izinkinga ezizimele - zithinta ngqo isivuno, izindleko, kanye nokuncintisana.

Ukuze kuxazululwe lezi zinselele, ubuchwepheshe obuthuthukisiwe bokumboza buyaba yinto ebalulekile. Ikakhulukazi, izinhlelo zokumboza isivinini esikhulu ezinezingqimba ezimbili ziya ngokuya zamukelwa emigqeni yokukhiqiza amabhethri yesimanje.

Uma kuqhathaniswa nezinqubo ezivamile, lezi zinhlelo zingenza okulandelayo:

• Thuthukisa ukusebenza kahle kokukhiqiza jikelele ngo 60–80%

• Finyelela isivinini sokumboza kufika ku 160 m/min

• Gcina ukunemba okuphezulu ngokulawula ukuphambuka ngaphakathi ±1.0%

• Qinisekisa ukuthi ukulawulwa kokuxineka okuzinzile ngaphakathi ±2N

• Ukunikeza ukusebenza komile okuqhubekayo ngokushintshashintsha komoya ≤ ±2%

Okubaluleke kakhulu, izinhlelo zokumboza ezihlanganisiwe zihlanganisa ukumboza, ukomisa, kanye nokugoqa zibe yinqubo eqhubekayo, ezenzakalelayo - enciphisa kakhulu ukungenelela ngesandla futhi ithuthukisa ukuzinza kokukhiqiza.

Ezinhlelweni zokusebenza zangempela, abakhiqizi abathuthukela ezinhlelweni zokumboza ezisezingeni eliphezulu babike ukuthuthuka kokusebenza kahle okungaphezu kwe- 30%, kanye nokwehla kwamazinga okukhubazeka kanye nokuchithwa kwezinto ezibonakalayo. Lokhu kuthuthukiswa kubaluleke kakhulu ezindaweni zokukhiqiza ezinomthamo omkhulu lapho ngisho nokwehluka okuncane kungaholela ekulahlekelweni okukhulu.

Kubakhiqizi abafuna izixazululo ezinokwethenjelwa, ubuchwepheshe bokumboza obuhlanganisiwe obuthuthukiswe abahlinzeki bemishini abanolwazi olufana nalokhu I-Pengjin zisetshenziswa kabanzi kokubili kumaphrojekthi okugcina amabhethri kagesi kanye nokugcina amandla. Lezi zinhlelo zenzelwe ukuphatha izinto ezincane kakhulu (isb., Ifoyili yethusi engu-4μm kanye nefoyili ye-aluminium engu-6μm) ngenkathi igcina ukusebenza kwesivinini esiphezulu kanye nokunemba okuphezulu.

Ngaphandle kwemishini ezimele, imishini yokumboza yesimanje ihlanganiswa kakhulu emigqeni yokukhiqiza egcwele, isebenza kanye nezinhlelo zokubuyisa ze-NMP, ukugoqa, kanye nezinqubo zokusika ukuze kwakhiwe uhlelo lokukhiqiza oluphelele oluhlakaniphile.

Njengoba imboni yamabhethri e-lithium iqhubeka nokukhula, ubuchwepheshe bokumboza abusaseyona nje into yokusebenzisa izinto - bumayelana nokuvumela ukukhiqizwa okukhuliswayo, kwekhwalithi ephezulu, futhi okonga izindleko.

Uma uhlela umugqa omusha wokukhiqiza ibhethri noma ulungisa osuvele ukhona, ukuqonda ukuthi izinhlelo zokumboza ezithuthukisiwe zithuthukisa kanjani ukusebenza kahle kanye nokungaguquguquki kungenza umehluko olinganiswayo emiphumeleni yakho.
