Uhlalutyo lwezinto zeCathode

Kwi-2012, iibhetri ze-lithium zibalelwa kwi-41% yemfuno ye-terminal ye-lithium yehlabathi. Igalelo kunye nokusebenza kwemveliso yebhetri ye-lithium kuxhomekeke kwisakhiwo kunye nokusebenza kwedatha yangaphakathi yebhetri. Ulwazi lwangaphakathi lwebhetri lubandakanya ulwazi olubi, i-electrolyte, i-membrane kunye nolwazi oluhle. Idatha echanekileyo yinkcazelo engundoqo engundoqo, i-akhawunti ye-30-40% yeendleko zebhetri ze-lithium. Ukwandiswa ngokukhawuleza kweevenkile ze-electronics zabathengi (ii-laptops, iipilisi, ii-smart phones, njl.njl.) kukhokelele ekunyukeni kwemfuno yeebhetri ze-lithium. Kwixesha elizayo, izithuthi zombane kunye nezityalo zokugcina amandla kwicandelo elitsha lamandla nazo ziya kuxhomekeka kwiibhetri ze-lithium. Ngo-2013, ishishini lebhetri ye-lithium yehlabathi kulindeleke ukuba lifikelele kwi-27.81 yeebhiliyoni zeedola zaseMelika. Kwi-2015, ukusetyenziswa kwemizi-mveliso yezithuthi zamandla amatsha kuya kuqhuba ishishini lebhetri ye-lithium yehlabathi ukufikelela kwi-US $ 52.22 billion. Ngokwandiswa kwesicwangciso soshishino lwebhetri ye-lithium, isicwangciso soshishino lwebhetri ye-Positive Data ikwinqanaba lokwandiswa ngokukhawuleza, kwaye ukusetyenziswa kwe-lithium cobalt oxide yeyona nto ivuthiweyo.

Sebenzisa ukubola kwecandelo ngedatha elungileyo

Idatha efanelekileyo yeebhetri ze-lithium ezisetyenziswayo ngoku kwaye ziphuhliswa ikakhulu zenziwe ngedatha ye-ternary ye-lithium cobalt acid, i-lithium nickel cobalt acid, i-nickel manganese cobalt, i-spinel lithium manganese acid kunye ne-olivine lithium iron phosphate. Kwilizwe lam, idatha ye-cathode ikakhulu ibandakanya i-lithium cobalt oxide, idatha ye-ternary, i-lithium manganate kunye ne-lithium iron phosphate. Udidi lwesicelo sokubola kwedatha efanelekileyo lubaluleke kakhulu. I-Lithium cobalt oxide isengumthombo obalulekileyo wedatha efanelekileyo kwiibhetri ze-lithium ezincinci, kwaye ibaluleke kakhulu kwiibhetri ze-lithium zendabuko ze-3C. Idatha ye-ternary kunye ne-lithium manganese oxide zizinto ezibalulekileyo zeebhetri ze-lithium ezincinci. EJapan naseMzantsi Korea, iteknoloji yebhetri ikhulile kwaye ibalulekile kwizixhobo zombane, iibhayisikili zombane kunye neenqwelo zombane. I-lithium iron phosphate isetyenziswa kakhulu kwilizwe lam kwaye isikhokelo sophuhliso lwexesha elizayo. Inexabiso elibalulekileyo lesicelo kwiinkalo zesikhululo sesiseko kunye neziko ledatha yokugcina amandla, ukugcinwa kwamandla ekhaya, kunye nokugcinwa kwamandla elanga.

I-lithium cobalt oxide iya kutshintshwa ngokuthe ngcembe

Inkqubo yokuvelisa i-lithium cobalt oxide ilula, ukusebenza kwe-electrochemical kuzinzile, kwaye yenye yeenzuzo zokuqala zokuthengisa ngokupheleleyo. Ineenzuzo zombane wokukhupha okuphezulu, intlawulo ezinzileyo kunye nombane wokukhupha, kunye nomlinganiselo ophezulu wamandla. Inezicelo ezibalulekileyo kwiimveliso zabathengi bebhetri encinci. Imakethi ye-elektroniki yabathengi ikhula ngokukhawuleza, kwaye ukuthengiswa kwe-lithium cobalt oxide yebhetri yecathode izinto ze-akhawunti yeyona nxalenye inkulu, kodwa inkunzi ephezulu ayihambisani nokhuseleko lokusingqongileyo, izinga elithile lokusetyenziswa kwamandla liphantsi, ubomi bebhetri bufutshane, kwaye ukhuseleko lumbi. Idatha ye-Ternary idibanisa iingenelo ze-lithium cobalt, i-lithium nickel kunye ne-lithium manganese kwaye inenzuzo yexabiso, kodwa ukusetyenziswa kwayo kuchaphazelekayo ngexabiso le-cobalt. Xa ixabiso le-cobalt liphezulu, ixabiso ledatha ye-ternary liphantsi kune-cobalt lithium, enokhuphiswano oluqinileyo lwemarike. Kodwa xa ixabiso le-cobalt liphantsi, inzuzo yedatha yetriad ehambelana ne-cobalt kunye ne-lithium incinci kakhulu. Okwangoku, ukutshintshwa kwedatha ye-lithium oxide ngedatha ye-ternary yindlela eqhelekileyo.

Idatha ye-ternary inenzuzo yeendleko eziphantsi

Idatha ye-ternary ilungiswa ngokuzisa i-nickel, i-cobalt, kunye ne-manganese kwinqanaba elithile, kwaye emva koko wazisa umthombo we-lithium. Imoto yokuqala yezemidlalo yeTesla yasebenzisa iibhetri ze-18650 ze-lithium cobalt oxide, ngelixa imodeli yayo yesibini yokuvelisa i-Model-s isebenzisa i-Panasonic ye-customized Ternary-Data ibhetri, eyibhetri ye-nickel-cobalt-aluminium. Ibhetri ye-Ternary-PositiveData. Iibhetri zeLithium cobalt oxide zibiza kakhulu, ngoko kunengqiqo ukuthelekisa ukusebenza kweemodeli ezimbini ngaphambi nangemva kweTesla. Imodeli s isebenzisa ngaphezu kweebhetri ze-8,000, ezingaphezulu kwe-1,000 ngaphezu kwe-Roadster. Nangona kunjalo, ngenxa yolawulo olungcono lweendleko zebhetri ye-3, ixabiso liye lancitshiswa nge-30%. Okwangoku, kusekho umsantsa omkhulu phakathi kwelizwe lam ibhetri ye-lithium yedatha ye-NCM ternary kunye nemarike yamazwe ngamazwe, kwaye kukho imiqobo emibini enkulu kwizixhobo kunye neteknoloji yokulawula uzinzo, kwaye uphuhliso lusemva ngokucacileyo. Isetyenziswe ngokubanzi kumazwe angaphandle, kodwa inkampani yethu ayinayo imveliso okwangoku.
