3. Tilmaamaha Alaabta
Nadiif sare iyo wasakh hoose: Waxa ku jira kaarboonka go'an guud ahaan waa inta u dhaxaysa 94% iyo 99.9%, iyo qaar sare - qeexida dhamaadka waxay gaadhi karaan in ka badan 99.95%; Waxa ku jira dambasku waa hooseeyaa (sida caadiga ah in ka yar ama la mid ah 0.1% -6%, lagu hagaajiyo rogaal celiska kaarboonka go'an), iyo wasakhda waxyeelada leh sida silikoon, aluminium, birta, iyo baaruudda si adag ayaa loo xakameeyaa heerar aad u hooseeya (sida macdanta birta In ka yar ama la mid ah 0.02%, sulfur content in ka yar ama la mid ah, wax soo saarka oo hoos u dhigaya 0.05%).
Qaab dhismeedka miisaanka oo dhamaystiranQaab-dhismeedka cabbirku waa mid joogto ah, dhexroorkiisu inta badan wuxuu u dhexeeyaa 0.1-1.5mm iyo dhumucdiisuna tahay 2-10μm. Qaab dhismeedka lakabka ah waa mid sugan; Muuqaalku waa dhalaal bir cawlan qalin ah, oo cufnaanta cufnaanta ah 1.0-1.6g/cm³. Qaab dhismeedkeeda miisaanka gaarka ah waxa ay siinaysaa simbiriirixan dhexda oo aad u wanaagsan iyo hawlkarnimo.
Sifooyin jidheed iyo kiimiko oo aad u wanaagsan: Sababtoo ah crystallinity sare iyo daahirsanaanta, waxa ay leedahay conductivity aad u fiican (casistance mugga In ka yar ama la mid ah 10μΩ · m) iyo conductivity kaamerada (thermal conductivity ka weyn ama la mid ah 150W / (m · K)); Iska caabin heerkul sare oo xoog leh, awood u leh inuu u adkeysto heerkulka ka sarreeya 3000 ee jawi aan firfircoonayn, iyo xasilloonida kiimikada aadka u fiican ee deegaanka acidic iyo alkaline (marka laga reebo asiidhyada oksida ee xooggan), taas oo ka dhigaysa mid aad u yar oo u nugul daxalka.
La qabsiga habaynta wanaagsan: Qaab dhismeedka miisaanku waa sahlan tahay in la burburiyo laakiin aan si fudud loo jebin budada ganaaxa, taas oo ka dhigaysa mid ku habboon ka-hortagga soo socda sida spheroidization, naqshadeynta, daboolka, iwm; Waxaan u habeyn karnaa cabbirka cabbirka iyo heerka daahirsanaanta iyadoo loo eegayo baahidayada, waxaanan la qabsan karnaa hababka hoose ee kala duwan. Tusaale ahaan, electrodes-ka lithium-ka taban waxay u baahan yihiin miisaanno ganaax ah (0.1-0.5mm), halka walxaha refractory ay u baahan yihiin miisaan qotodheer (0.8-1.5mm).
4. Isticmaalka Alaabta
Alaabooyinka ceeriin ee asaasiga ah ee lithium{0}}iyooyinka walxaha korantada taban: Sida alaabta aasaasiga ah ee sare -awood lithium{1} ion negative electrodes, graphite spherical waxaa lagu sameeyaa habab sida burburinta, spheroidization, iyo daahan, waxaana loo isticmaalaa baytariyada korontada (gaadiidka tamarta cusub), baytariyada kaydinta tamarta (saldhigyada tamarta kaydinta tamarta), iyo sare{2}} dhamaadka baytariyada macaamiisha, drones; Nadiifinta sare waxay kor u qaadi kartaa awoodda gaarka ah ee batteriga (Ka weyn ama la mid ah 360mAh/g) iyo nolosha wareegga (Ka weyn ama la mid ah wareegyada 2000).
Sare -dhamaadka wax buuxinaya: Lagu daray balaastiig, caag, iyo dahaarro si loo sameeyo walxo isku dhafan, oo loo isticmaalo daasadaha qalabka elegtarooniga ah (anti{0}static), shabbaadaha dhegaha baytariga lithium ( xidhidhiyaha wax qabad), iyo moduleka sawir-qaadka ah; Dhaqdhaqaaqa sare wuxuu yarayn karaa iska caabbinta walxaha, wanaajin kartaa isku mid ahaanshaha conductivity, oo dabooli kara baahiyaha elektaroonigga sare{1}.
Qaybaha maaddooyinka ee gaarka ah: Sare -Kaarbon Flake Graphite waxa loo isticmaalaa soo saarista lebenka refractory sare{1} Nadiifinta sare iyo iska caabinta heerkulka sare waxay kor u qaadi kartaa caabbinta nabaad-guurka slag ee alaabada refractory waxayna kordhisaa noloshooda adeeg (30% -50% ka sarreeya qalabka caadiga ah ee garaafyada).
Saliidaha saxda ah iyo agabka wax lagu xidhoWaxaa lagu sameeyay saliidaha garaafyada (oo loo isticmaalo saliidaynta matoorada duulista iyo qaybaha qalabka mashiinka saxda ah), iyadoo la adeegsanayo is-dhex-galka is-dhex-galka si loo yareeyo isku-dhafka isku-dhafka (In ka yar ama la mid ah 0.15); Ama loo habeeyey shaabado garaafyo dabacsan (oo loogu talagalay dhuumaha iyo shaabadda valve), oo leh caabbinta heerkulka sare iyo hooseeya labadaba (-200 ° ~ 600 digrii) iyo caabbinta cadaadiska sare (In ka yar ama la mid ah 30MPa) sifooyinka.
Garoomada kale ee sare-: Waxaa loo isticmaalaa qaybaha garaafyada warshadaha nukliyeerka ( wasakhda hoose waxay yareyn kartaa nuugista shucaaca), horudhaca diyaarinta graphene (nadiifinta sare waxay yaraynaysaa dhibka nadiifinta graphene), sare {{0}dhammaadka hogaaminta qalin-qoritaan ( dhalaal badan iyo faseexatin qoraal ) iyo meelo kale, ku tiirsanaanta nadiifinta iyo faa'iidooyinka qaabdhismeedka si loo ballaariyo xuduudaha codsiga.
