Ukuhlaziywa kwempahla ye-Cathode

Ngo-2012, amabhethri e-lithium abalelwa ku-41% wesidingo se-lithium terminal. Ukusebenza kokufakwayo nokuphumayo kwebhethri le-lithium kuncike esakhiweni nasekusebenzeni kwedatha yangaphakathi yebhethri. Ulwazi lwangaphakathi lwebhethri luhlanganisa ulwazi olungalungile, i-electrolyte, ulwelwesi nolwazi oluhle. Idatha eqondile iwukhiye wolwazi oluyisisekelo, olubalelwa ku-30-40% wezindleko zamabhethri e-lithium. Ukwanda okusheshayo kwezitolo zama-electronics abathengi (amakhompyutha aphathekayo, amaphilisi, amafoni ahlakaniphile, njll.) kuholele ekwenyukeni kwesidingo samabhethri e-lithium. Esikhathini esizayo, izimoto zikagesi nezitshalo zokugcina amandla emkhakheni omusha wamandla nazo zizothembela kumabhethri e-lithium. Ngo-2013, imboni yomhlaba wonke yebhethri ye-lithium kulindeleke ukuthi ifinyelele kumadola ayizigidi eziyizinkulungwane ezingama-27.81. Ngo-2015, ukusetshenziswa kwezimboni kwezimoto zamandla amasha kuzoshayela imboni yebhethri ye-lithium emhlabeni wonke ukuze ifinyelele ku-US $ 52.22 billion. Ngokunwetshwa kohlelo lwemboni yebhethri ye-lithium, uhlelo lwemboni yebhethri ye-lithium ye-Positive Data nalo lisesigabeni sokunwetshwa ngokushesha, futhi ukusetshenziswa kwe-lithium cobalt oxide yikona okuvuthwe kakhulu.

Sebenzisa ukubola kwesigaba ngedatha evumayo

Idatha enhle yamabhethri e-lithium asetshenziswayo futhi athuthukiswayo njengamanje ahlanganiswe ikakhulukazi idatha ye-ternary ye-lithium cobalt acid, i-lithium nickel cobalt acid, i-nickel manganese cobalt, i-spinel lithium manganese acid ne-olivine lithium iron phosphate. Ezweni lami, idatha ye-cathode ikakhulukazi ihlanganisa i-lithium cobalt oxide, idatha ye-ternary, i-lithium manganate ne-lithium iron phosphate. Ukuhlukaniswa kwesigaba sohlelo lokusebenza kwedatha evumayo kubaluleke kakhulu. I-Lithium cobalt oxide isewumthombo obalulekile wedatha evumayo yamabhethri amancane e-lithium, futhi ibaluleke kakhulu kumabhethri e-lithium endabuko angu-3C. Idatha ye-ternary kanye ne-lithium manganese oxide yizingxenye ezibalulekile zamabhethri amancane e-lithium. E-Japan naseNingizimu Korea, ubuchwepheshe bebhethri sebuvuthiwe futhi bubalulekile kumathuluzi kagesi, amabhayisikili kagesi kanye nezimoto zikagesi. I-Lithium iron phosphate isetshenziswa kabanzi ezweni lami futhi iyisiqondiso sentuthuko yesikhathi esizayo. Inenani elibalulekile lohlelo lokusebenza emikhakheni yesiteshi esiyisisekelo kanye nendawo yokugcina amandla kagesi, isitoreji samandla sasekhaya, nesitoreji samandla elanga.

I-lithium cobalt oxide izoshintshwa kancane kancane

Inqubo yokukhiqiza ye-lithium cobalt oxide ilula, ukusebenza kwe-electrochemical kuzinzile, futhi kungenye yezinzuzo zokuqala zokuthengisa okugcwele. Inezinzuzo ze-voltage ephezulu yokukhipha, ukushaja okuzinzile kanye ne-voltage yokukhipha, kanye nesilinganiso samandla aphezulu. Inezinhlelo zokusebenza ezibalulekile emikhiqizweni yabathengi bebhethri encane. Imakethe ye-elekthronikhi yabathengi ikhula ngokushesha, futhi ukuthengiswa kwe-lithium cobalt oxide battery cathode materials akhawunti ingxenye enkulu, kodwa imali ephezulu ayihambisani nokuvikelwa kwemvelo, izinga elithile lokusebenzisa amandla liphansi, impilo yebhethri ifushane, futhi ukuphepha kubi. Idatha ye-Ternary ihlanganisa izinzuzo ze-lithium cobalt, i-lithium nickel ne-lithium manganese futhi inenzuzo yentengo, kodwa ukusetshenziswa kwayo kuthinteka ngentengo ye-cobalt. Lapho intengo ye-cobalt iphezulu, intengo yedatha ye-ternary iphansi kunaleyo ye-cobalt lithium, enokuncintisana okuqinile kwemakethe. Kodwa lapho intengo ye-cobalt iphansi, inzuzo yedatha ye-triad ehlobene ne-cobalt ne-lithium incane kakhulu. Njengamanje, ukushintshwa kwedatha ye-lithium oxide ngedatha ye-ternary kuwumkhuba ojwayelekile.

Idatha ye-Ternary inenzuzo yezindleko eziphansi

Idatha ye-ternary ilungiswa ngokwethula i-nickel, i-cobalt, ne-manganese engxenyeni ethile, bese kwethulwa umthombo we-lithium. Imoto yokuqala yezemidlalo kaTesla yasebenzisa amabhethri e-lithium cobalt oxide angu-18650, kuyilapho imodeli yayo yesibili yokukhiqiza i-Model-s isebenzisa ibhethri le-Panasonic elenziwe ngokwezifiso le-Ternary-Data, okuyibhethri le-nickel-cobalt-aluminium. Ibhethri le-Ternary-PositiveData. Amabhethri e-lithium cobalt oxide ayabiza, ngakho-ke kunengqondo ukuqhathanisa ukusebenza kwamamodeli amabili ngaphambi nangemuva kweTesla. Imodeli s isebenzisa amabhethri angaphezu kuka-8,000, angaphezu kuka-1,000 ngaphezu kwe-Roadster. Nokho, ngenxa yokulawulwa kwezindleko ezingcono zebhethri lezindlela ezi-3, izindleko zehliswe ngo-30%. Okwamanje, kusekhona igebe elikhulu phakathi kwedatha yezwe lami ye-lithium yebhethri ye-NCM ternary kanye nemakethe yamazwe ngamazwe, futhi kunezithiyo ezimbili ezinkulu kumishini nobuchwepheshe bokulawula ukuzinza, futhi intuthuko ngokusobala isalele emuva. Isetshenziswe kabanzi phesheya, kodwa inkampani yethu ayinayo imikhiqizo okwamanje.
