Ingabe ukutholwa kwebhethri okungu-100%? Okunamathiselwe endleleni yokuphinda kucutshungulwe izinhlobo ezahlukene zamabhethri

Umbhali :Iflowpower - Umhlinzeki Wesiteshi Samandla Esiphathekayo

Noma yimuphi umkhiqizo wezimboni uzokhiqiza inani lokuvikelwa kwemvelo inqobo nje uma ukukhiqizwa kwenani elikhulu endaweni eyodwa, futhi ukukhiqizwa ngobuningi kuzothuthukisa ukusetshenziswa kwamandla, futhi ukuvikelwa kwemvelo kwemvelo kukaphethiloli nogesi kungenangqondo. Imoto entsha yamandla ingase incike ikakhulukazi kuzwelonke kanye nesifunda kumandla kawoyela ezweni. Ukuthi kuncike kakhulu.

Izimoto ezintsha zamandla ziwuhlelo lokusabela ezinkingeni zamandla, futhi ukuvikelwa kwemvelo kuwungqimba nje lwezingubo zangaphandle. Ingabe ukugaywa kabusha kwebhethri kuyalingana nokuvikelwa kwemvelo? UMask usanda kusho ukuthi ibhethri likaTesla lingalulama i-100%, lihlanganiswe nohlelo lukaTesla lwe-lithium-ion lokubuyisela ibhethri, lolu hlelo luhambisana ngokuphelele nemvelo, futhi imiphumela iyamangalisa. Khona-ke, ochwepheshe bakwamanye amazwe baphuma ekugxekeni, okwamanje alikho ibhethri lesimanje elingatholwa ngo-100% ngoba kunenani elikhulu lezinto ezingezona amalahle.

"Ukuthola kabusha okungu-100%" embikweni we-Tesra kubonakala sengathi "u-100% webhethri likadoti uzotholwa ngandlela thile", hhayi "ukuthola kabusha okungu-100% ngebhethri ngalinye". Eqinisweni, izinsimbi ezisindayo ku-lithium iron phosphate nebhethri ye-lithium ye-ternary zingagaywa kabusha, kodwa izindleko zokutakula ziphezulu. Kukhona idatha, futhi ibhethri ye-lithium iron phosphate yamanje ithoni eli-1 itholwa ngezinqubo eziningi zokuhlanza izinsimbi ezisindayo, ezifinyelela kumayuan angu-8,500, kodwa inani lemakethe lensimbi ewumphumela lingamayuan angu-9,000 kuphela.

Ibhethri elilodwa lebhotela lingangcoliswa ngamanzi angu-600,000, cishe amanzi okuphuza omuntu. Indlela yokubhekana nezindaba zangempela zezemvelo. Isizathu esisodwa sezindleko eziphezulu zokutholwa kwebhethri ukuthi izinkampani ezinkulu ezinsukwini zokuqala zemboni zilangazelela ukuba nazo muva nje, futhi ngeke zikhuthaze izimboni eziphezulu ze-value-added.

Ngokuthuthuka kwemboni, ukugaywa kabusha kuzoba ibhizinisi, futhi indawo yangempela izofika. Ukukhiqizwa, ukugaywa kabusha, ukukhiqizwa kwamandla, ukusetshenziswa, nokugaywa kabusha kwemikhiqizo yamandla emisha eyimpikiswano amaluphu amabili avaliwe, futhi ahlotshaniswa nenye. Izimoto zamandla amasha zinezinzuzo zemvelo ezisetshenziswayo, ezingakwazi ukuphikisa.

Ukushayela ngesivinini esiphezulu ngenxa yezinkinga zokumelana nomoya kubangela ukusetshenziswa kwamandla aphezulu, ngakho ukuphila kwebhethri bekulokhu kuyinkinga. Yehlisa ukusetshenziswa kwamandla futhi uthuthukise izinaliti ezimbili zomsebenzisi, ngakho-ke utshalomali lwemoto yamandla entsha endaweni evumelana nemvelo kufanele lusebenze kanzima kulezi zici ezimbili. I-lightweight, enciphisa imoto yamandla amasha ekwazi ukumelana nomoya ngokuphepha, yinkambiso yesikhathi esizayo.

Izinkinga zemvelo zokukhiqiza amandla ziyizinkundla ezinkulu zezingxabano, futhi isitatimende esingenanhlonipho sikagesi silingana namalahle avuthayo besilokhu sikhona. Empeleni ilawula ngokuqinile ukwakhiwa kwezitshalo zamandla omlilo ngo-2016. Ngo-2017, izinto zikagesi ezintsha zezwe lami ezikhiqizwe zaba ngu-53.

7%, esedlule uhhafu. Ekuvikelweni kwemvelo, izenzo zezwe zishesha kakhulu kunemboni entsha yamandla. Isizathu sokuthi kungani amandla amasha akhuthazwa kabanzi ukuthi uchungechunge lwemboni ye-petrochemical luyinkimbinkimbi futhi lude, abaphakathi nabo baningi, futhi ukuphathwa okuphakathi nendawo kuphezulu, futhi amandla amasha kanye ne-inthanethi ziyakhula ngokuvumelanisa.

Isihluthulelo ukusebenza kahle, ukuvikelwa kwemvelo Imikhiqizo etholakalayo. Inqubo yokutakula amabhethri ahlukene iqukethe i-lithium iron phosphate ibhethri imfucuza ye-phosphate positive electrode izinto eziqukethe insimbi ecebile, i-lithium, njll. Inani elitholwe kakhulu yi-lithium, futhi insimbi inenani elithile lokutakula, kanti enye ingxenye iphansi.

Ngenxa yenani eliphakeme lensimbi efana ne-waste phosphate ayiyona i-cobalt, i-nickel iyinsimbi enenani eliphakeme, inani lokubuyisela liphansi kunezinye izinhlobo zamabhethri e-lithium ion angcolile njengezinto ze-NCM ternary. Ngakho-ke, izidingo ezisezingeni eliphezulu kanye nezindleko eziphansi zebhethri lemfucuza ye-phosphate enqubweni yokubuyisela ziphezulu. Njengamanje, isihloli se-phosphate sikadoti sisetshenziselwa ukubuyisela izakhi zensimbi ezibalulekile ezintweni ezinhle zamaseli e-phosphate emvula ngokusansimbi okumanzi.

I-phosphithium iron phosphithoxia edoti ikhishwa, i-lithium, insimbi ne-phosphorus, njll., uketshezi lwe-leaching lungaphansi kwesisombululo ngendlela ye-ionic, futhi uketshezi oluphumayo luhlukaniswa futhi lubuyiselwe nge-lithium, izakhi zensimbi. I-lithium ivame ukutholwa isesimweni se-lithium carbonate ne-lithium phosphate, futhi insimbi ngokuvamile itholwa njenge-iron phosphate ne-iron hydroxide.

I-leaching agent ikakhulukazi i-inorganic acid, njenge-sulfuric acid, i-nitric acid ne-hydrochloric acid, njll. futhi isebenzisa i-asidi ephilayo ukuvuza; i-oxidant ngokuvamile isebenzisa i-hydrogen peroxide. Insimbi ewusizo ye-phosphate imfucuza ingatholwa kusetshenziswa inqubo emanzi.

Ibhethri le-lead-acid linebhethri enkulukazi yezimboni yamabhethri okugcina umthofu. Umthofu wenze ngaphezu kuka-50% yenani eliphelele lebhethri, ikakhulukazi kusetshenziswa umlilo, ubuchwepheshe bensimbi obumanzi, kanye nobuchwepheshe bokunciphisa i-electrolysis yesigaba esiqinile. I-casing yangaphandle iyipulasitiki, engavuselelwa kabusha.

Amabhethri e-lead-acid ngokuvamile anezindlela ezintathu zokutakula: a. Ubuchwepheshe bokubuyisela kabusha obuhlelwa mathupha ngokuvamile buhlukaniswa ngamabhethri omile, ahlukaniswe kalula nesikhumba se-zinc, isembozo sepulasitiki, induku yekhabhoni, njll., insalela, itshe lamanzi-manganese, njll.

Le ndlela ilula futhi ilula, kodwa idinga abasebenzi abaningi, futhi izinzuzo zezomnotho azinkulu. b. Ngemva kobuchwepheshe bokuvuselela umlilo, ibhethri elomile lihlukaniswa, liphukile, futhi i-rotary kiln ithunyelwa kuhhavini elijikelezayo.

Emazingeni okushisa aphezulu angu- ~ degrees Celsius, i-zinc ne-zinc chloride ifakwa i-oxid ku-zinc oxide njengegesi yentuthu, futhi i-zinc oxide itholwa ngomqoqi wothuli lwe-cyclone. I-manganese dioxide eyinsalela kanye ne-hydromestone ingena endaweni esele, iphinde ibuyise izinto ezifana ne-manganese, le ndlela ilula, futhi isincibilikisi esivamile asikho isidingo sokwandisa izisetshenziswa zokubuyisela i-zinc. C.

Ubuchwepheshe bokubuyisela kabusha obumanzi, ngokusho kwesimiso se-zinc kanye ne-manganese dioxide ingancibilika kumgomo we-asidi, ngemva kokuchotshozwa, ibekwe endaweni ye-leaching slot, enezela i-dilute sulfuric acid (~ L) ye-leaching, okuholela kusisombululo se-zinc sulfate, i-electrolysis etholakalayo Indlela yenziwe nge-zinc yensimbi. Izinsalela zokuhlunga zihlukaniswa nekepisi yethusi. Ngemva kwe-carbon rod, insalela, kanye netshe le-manganese yamanzi liyabalwa.

Indlela esetshenziswayo inendlela yokuleaching exakile kanye nendlela yokuleaching eqondile. Ukugaywa kabusha kwebhethri lama-yuan amathathu amoshayo anobukhulu obuthathu bungenzeka ngokwezomnotho okuphezulu, ubuchwepheshe bokwenza kabusha kokuhlukaniswa komzimba bufaneleka kakhulu ezinhlelweni ezisebenza ekugayweni kabusha kwamabhethri e-ternary, kanye nendlela yokutakula eyinhloko esetshenziswa kubuchwepheshe basekhaya nabangaphandle obuhola amabhizinisi okugaya kabusha.
