Qhov zoo electrode yog lub luag haujlwm tseem ceeb rau kev muab cov lithium ions thiab electrons xav tau rau kev tso tawm. Nws feem ntau yog ua los ntawm lithium composite oxides (xws li cov ntaub ntawv ternary, lithium hlau phosphate). Qhov kev xaiv ntawm cov khoom siv ncaj qha txiav txim siab lub zog ceev thiab qib voltage ntawm lub roj teeb. Piv txwv li, lub zog siab ceev ntawm ternary lithium roj teeb yog ntaus nqi rau cov yam ntxwv ntawm cov khoom siv electrode zoo; thaum muaj kev nyab xeeb siab ntawm lithium hlau phosphate roj teeb muaj feem xyuam nrog cov qauv ruaj khov ntawm cov khoom siv electrode zoo.
Qhov tsis zoo electrode yog lub luag haujlwm rau kev txais thiab khaws cia lithium ions. Cov khoom siv tsis zoo electrode feem ntau yog graphite, thiab qee qhov siab - cov roj teeb kawg yuav suav nrog silicon- cov ntaub ntawv raws li cov khoom siv kom muaj peev xwm. Thaum lub sij hawm them nyiaj, lithium ions raug tso tawm los ntawm qhov zoo electrode, dhau los ntawm cov electrolyte thiab cov khoom sib cais, thiab muab tso rau hauv lub qhov hws ntawm cov khoom tsis zoo electrode; Thaum lub sij hawm tso tawm, cov lithium ions rov qab tso tawm los ntawm qhov tsis zoo electrode, rov qab mus rau qhov zoo electrode thiab tso cov hluav taws xob los tsim hluav taws xob tam sim no.
Lub electrolyte yog lub luag hauj lwm rau tso cai rau lithium ions kom dawb do txav ntawm qhov zoo thiab tsis zoo electrodes. Nws feem ntau muab faib ua kua electrolytes thiab khoom electrolytes. Tam sim no, kua electrolytes tseem yog lub hauv paus hauv cov roj teeb, muaj lithium ntsev, organic solvents, thiab additives. Lub ionic conductivity thiab stability ntawm cov electrolyte ncaj qha cuam tshuam rau lub charger ceev thiab lub voj voog lub neej ntawm lub roj teeb - siab- zoo electrolytes pab kom ceev kis ntawm lithium ions thaum tsis txhob muaj kev phiv los ntawm qhov zoo thiab tsis zoo electrodes.
Cov khoom sib cais yog ib daim nyias nyias, feem ntau yog ua los ntawm polyethylene lossis polypropylene. Nws lub cev cais tawm qhov zoo thiab tsis zoo electrodes, tiv thaiv kev sib cuag ncaj qha ntawm lawv thiab zam kev luv luv. Nyob rau tib lub sijhawm, cov qauv ntxeem tau ntawm cov khoom sib cais tso cai rau lithium ions kom dhau los ntawm kev sib luag yam tsis muaj kev cuam tshuam rau lub zog xa mus. Thaum lub roj teeb kub siab dhau lawm, qee qhov sib cais yuav ua rau lawv qhov pore diameters los ntawm "thermal kaw pore" cov cuab yeej los tiv thaiv kev txav ntawm lithium ions, yog li tiv thaiv thermal runaway thiab ntxiv "ob daim ntawv pov hwm" rau roj teeb kev nyab xeeb.
Cov plaub yam no zoo li lub qhov dej -kev sib koom tes "pab": cov electrode zoo muab lub zog, cov electrode tsis zoo khaws lub zog, cov electrolyte thauj lub zog, thiab cov khoom sib cais tiv thaiv kev nyab xeeb. Nws yog lawv txoj haujlwm sib koom tes uas ua rau lub roj teeb ruaj khov thiab tsis tu ncua muab lub zog rau lub xov tooj ntawm tes, tsheb, lub zog cia khoom, thiab lwm yam, dhau los ua lub zog tseem ceeb hauv lub neej niaj hnub no.
