Kev nkag siab ua ntej txog cov roj teeb lithium
Txais tos rau hauv lub blog Heltec Energy official! Cov roj teeb lithium-ion tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub, muab hluav taws xob rau cov khoom siv uas peb vam khom, xws li cov xov tooj ntse thiab cov laptops, thiab txawm tias cov tsheb. Tus qauv ntawm lub roj teeb tau tsim nyob rau hauv xyoo pua 18th lig, thiab nws tau ntau tshaj ob puas xyoo txij li thaum ntawd los. Cov roj teeb Lithium-ion yog ib hom roj teeb tshiab tshaj plaws uas tau yug los hauv cov txheej txheem ntawm kev tsim roj teeb.
Cov roj teeb raug muab faib ua cov roj teeb qhuav uas tsuas yog siv tau ib zaug xwb, "cov roj teeb tseem ceeb", thiab cov roj teeb uas tuaj yeem rov them dua thiab siv ntau zaus, "cov roj teeb thib ob". Cov roj teeb Lithium-ion yog cov roj teeb thib ob uas tuaj yeem rov them dua. Piv nrog rau lwm hom roj teeb, cov roj teeb lithium-ion tshwj xeeb hauv lawv qhov me me thiab lub teeb yuag, ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob nqa tau. Tsis tas li ntawd, lawv muaj peev xwm khaws cia ntau lub zog hluav taws xob, ua rau lawv yog qhov chaw siv hluav taws xob zoo.
Cov roj teeb lithium-ion tsim hluav taws xob li cas
Lub hauv paus ntsiab lus ua haujlwm yooj yim ntawm cov roj teeb zoo sib xws, suav nrog lub electrode zoo (cathode), lub electrode tsis zoo (electrode tsis zoo), thiab electrolyte. Sab hauv lub roj teeb, cov electrolyte tso cai rau cov ions hla dhau, thaum cov electrons ntws los ntawm lub electrode tsis zoo mus rau lub electrode zoo, yog li tsim cov hluav taws xob tam sim no. Rau cov roj teeb theem nrab, xws li cov roj teeb lithium-ion, lawv tuaj yeem khaws cov electrons hauv lub electrode tsis zoo ua ntej los ntawm kev them, thiab thaum lub roj teeb raug tso tawm, cov electrons no ntws mus rau lub electrode zoo, yog li tsim hluav taws xob.
Tom ntej no, cia peb saib cov yam ntxwv thiab qhov zoo ntawm cov roj teeb lithium-ion. Qhov laj thawj uas ua rau cov roj teeb lithium-ion sawv tawm ntawm ntau lub roj teeb feem ntau yog vim lawv cov qauv tshwj xeeb thiab kev xaiv cov khoom siv. Ua ntej, cov roj teeb lithium-ion siv cov hlau sib xyaw ua ke uas muaj lithium ntawm qhov hluav taws xob zoo thiab cov pa roj carbon (xws li graphite) uas tuaj yeem nqus thiab khaws cia lithium ntawm qhov hluav taws xob tsis zoo. Qhov kev tsim no tso cai rau cov roj teeb lithium-ion tsim hluav taws xob yam tsis tas yuav rhuav tshem cov electrodes los ntawm kev yaj cov electrolyte zoo li cov roj teeb ib txwm muaj, yog li ua rau qeeb qeeb ntawm lub roj teeb laus. Qhov thib ob, lithium yog ib qho khoom me me thiab sib dua, uas ua rau cov roj teeb lithium-ion me dua thiab sib dua ntawm tib lub peev xwm. Tsis tas li ntawd, cov roj teeb lithium-ion kuj muaj qhov zoo ntawm lub zog ceev ceev, lub neej ntev, thiab tsis muaj kev cuam tshuam nco, tag nrho cov no tau ua rau cov roj teeb lithium-ion siv dav hauv cov khoom siv hluav taws xob nqa tau, tsheb fais fab thiab lwm yam teb.
Kev faib tawm ntawm cov roj teeb lithium
Cov roj teeb lithium-ion raug muab faib ua ntau pawg raws li cov khoom siv hlau siv rau hauv lub electrode zoo. Thaum xub thawj, cov khoom siv hlau siv rau hauv lub electrode zoo ntawm cov roj teeb lithium-ion yog cobalt. Txawm li cas los xij, kev tsim cov cobalt yuav luag qis npaum li lithium, thiab nws kuj yog ib qho hlau tsis tshua muaj, yog li tus nqi tsim khoom siab. Yog li ntawd, cov khoom pheej yig thiab zoo rau ib puag ncig xws li manganese, nickel, thiab hlau pib siv. Cov roj teeb lithium-ion raug faib raws li cov khoom siv uas lawv siv. Cia peb saib cov yam ntxwv ntawm txhua pawg.
| Hom roj teeb Lithium-ion | Hluav taws xob | Lub sijhawm tso tawm | Cov Zoo thiab Cov Tsis Zoo |
| Cov roj teeb lithium-ion uas siv cobalt | 3.7V | 500 ~ 1000 zaug |
|
| Cov lithium-ion uas muaj manganese | 3.7V | 300 ~ 700 zaug |
|
| Cov roj teeb lithium-ion uas ua los ntawm hlau phosphate | 3.2V | 1000 ~ 2000 zaug |
|
| Cov roj teeb lithium-ion uas siv tau 3 hom | 3.6V | 1000 ~ 2000 zaug |
