Kev nkag siab ua ntej ntawm lithium roj teeb
Txais tos rau lub official Heltec Energy blog! Cov roj teeb lithium-ion tau dhau los ua ib feem tseem ceeb ntawm peb lub neej niaj hnub, cov khoom siv hluav taws xob uas peb tso siab, xws li smartphones thiab laptops, thiab txawm tias lub tsheb. Tus qauv ntawm lub roj teeb tau tsim nyob rau hauv lub xyoo pua 18th, thiab nws tau muaj ntau tshaj li ob puas xyoo txij thaum ntawd los. Cov roj teeb lithium-ion yog ib yam tshiab ntawm cov roj teeb uas tau yug los hauv cov txheej txheem ntawm kev txhim kho roj teeb.
Cov roj teeb tau muab faib ua cov roj teeb qhuav uas siv tau ib zaug xwb, "cov roj teeb tseem ceeb", thiab cov roj teeb uas tuaj yeem siv tau thiab siv ntau zaus, "cov roj teeb thib ob". Cov roj teeb lithium-ion yog cov roj teeb thib ob uas tuaj yeem them rov qab. Piv nrog rau lwm hom roj teeb, cov roj teeb lithium-ion yog qhov tshwj xeeb hauv lawv qhov loj me thiab lub teeb yuag, ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob portable. Tsis tas li ntawd, lawv muaj peev xwm khaws cov khoom siv hluav taws xob ntau, ua rau lawv muaj peev xwm ua tau zoo.
Yuav ua li cas cov roj teeb lithium-ion tsim hluav taws xob
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov roj teeb zoo sib xws, suav nrog cov electrode zoo (cathode), tsis zoo electrode (tsis zoo electrode), thiab electrolyte. Nyob rau hauv lub roj teeb, cov electrolyte tso cai rau ions dhau mus, thaum electrons ntws los ntawm qhov tsis zoo electrode mus rau qhov zoo electrode, yog li tsim hluav taws xob tam sim no. Rau cov roj teeb theem nrab, xws li lithium-ion roj teeb, lawv tuaj yeem khaws cov hluav taws xob hauv qhov tsis zoo electrode ua ntej los ntawm kev them nyiaj, thiab thaum lub roj teeb tawm, cov electrons ntws mus rau qhov zoo electrode, yog li tsim hluav taws xob.
Tom ntej no, cia saib cov yam ntxwv thiab qhov zoo ntawm lithium-ion roj teeb. Yog vim li cas vim li cas cov roj teeb lithium-ion sawv ntawm ntau lub roj teeb feem ntau yog vim lawv cov qauv tshwj xeeb thiab xaiv cov khoom siv. Ua ntej, cov roj teeb lithium-ion siv lithium-muaj hlau sib txuas ntawm qhov zoo electrode thiab carbon (xws li graphite) uas tuaj yeem nqus tau thiab khaws cia lithium ntawm qhov tsis zoo electrode. Qhov kev tsim no tso cai rau cov roj teeb lithium-ion los tsim hluav taws xob yam tsis tas yuav decompose cov electrodes los ntawm melting cov electrolyte zoo li cov roj teeb ib txwm muaj, yog li ua kom qeeb ntawm kev laus ntawm lub roj teeb. Qhov thib ob, lithium yog ib qho me me thiab lub teeb, uas ua rau cov roj teeb lithium-ion ntau dua thiab sib zog ntawm tib lub peev xwm. Tsis tas li ntawd, cov roj teeb lithium-ion kuj muaj qhov zoo ntawm lub zog ceev, lub neej ntev ntawm lub voj voog, thiab tsis muaj kev nco, tag nrho cov no tau ua cov roj teeb lithium-ion dav siv hauv cov khoom siv hluav taws xob portable, hluav taws xob tsheb thiab lwm yam haujlwm.
Classification ntawm lithium roj teeb
Cov roj teeb lithium-ion tau muab faib ua ntau pawg raws li cov khoom siv hlau siv hauv qhov zoo electrode. Thaum pib, cov khoom siv hlau siv nyob rau hauv qhov zoo electrode ntawm lithium-ion roj teeb yog cobalt. Txawm li cas los xij, kev tsim cov cobalt yuav luag tsawg li ntawm lithium, thiab nws kuj yog cov hlau tsis tshua muaj, yog li tus nqi tsim khoom yog siab. Yog li ntawd, cov khoom pheej yig thiab zoo ib puag ncig xws li manganese, nickel, thiab hlau pib siv. Cov roj teeb lithium-ion raug cais raws li cov khoom siv uas lawv siv. Cia peb saib cov yam ntxwv ntawm txhua pawg.
| Hom ntawm Lithium-ion roj teeb | Qhov hluav taws xob | Lub sijhawm tso tawm | Pros thiab Cons |
| Cobalt-based lithium-ion roj teeb | 3.7v ua | 500 ~ 1000 zaug |
|
| Manganese-based lithium-ion | 3.7v ua | 300-700 zaug |
|
| Hlau phosphate-based lithium-ion roj teeb | 3.2v ua | 1000 ~ 2000 zaug |
|
| Ternary-based lithium-ion roj teeb | 3.6v ua | 1000 ~ 2000 zaug |
