Hababka tijaabada ah ee diyaarinta isku-dhafka Silicon-carbon

Halabuurka isku-dhafka silikoon-cb ayaa la tijaabiyay iyadoo la isticmaalayo xalinta plasma processing (SPP). Natiijooyinku waxay muujinayaan in habka SPP uu yahay hab aad u fiican oo loogu diyaariyo kaarboon madow oo leh mugga daloolka sare, dhexdhexaad ah iyo qaab dhismeedka daloolada yaryar. 0-22

“Daraasadahan, kaliya dareerayaasha organic sida benzene ayaa loo isticmaalay in lagu soo saaro CB. Si kastaba ha ahaatee, daraasaddan, waxaan ku baarnay ka kooban walxaha isku dhafan anagoo nanoparticles silicon nanoparticles ee dareeraha organic ka hor inta aan la saarin balaasmaha.

Tijaabada ayaa lagu sameeyay heerkulka qolka iyo cadaadiska. Isticmaalka labo ka mid ah qalin qorida makaanikada ah sida korantada ee soo ifbaxa balasmaha, maadaama inta badan fiilooyinka ay yihiin balaasmaha sputtering ama uumiga, waxaa loo qaadan karaa inay wasakh ku jiraan walxaha isku dhafan.

Electrode kasta waxa lagu daboolaa tuubo dhoobo ah oo la geliyo fur silikoon ah. Lamaanaha elektiroonigga ah ayaa lagu baakadeeyay tuubo dhoobo ah waxaana laga buuxiyaa baloogyo silikoon ah, ka dibna korantada waxaa lagu dhejiyaa berkad dhexroorkeedu yahay 50 mm dhererkiisuna yahay 100 mm (Jaantuska 1). Fogaanta u dhaxaysa electrodes-ka waxaa lagu hayaa 1 mm. Kaarboonka horudhaca ah waa xylene saafi ah (darajada reagent, sigma-aldrich), iyo silicon nanopowder (xajmiga qayb ka mid ah = 100nm, AlfaAesar) waxaa lagu qasaa xylene. Korontada garaaca wadnaha laba-cirifoodka waxaa loo isticmaalaa in lagu dhaliyo dareeraha. Inta jeer ee awoodda iyo ballaca garaaca garaaca waxaa lagu hagaajiyay 25khz iyo 0.5s siday u kala horreeyaan. Ka dib marka la sii daayo, dareeraha dheecaanka ayaa lagu sifeeyaa cellophane si loo helo wax kasta oo isku dhafan oo adag oo ku jira xalka. Ka dib shaandhayso, 80 darajo Celsius, waa monotonous, oo ka tagaya walxo budada ah.

Xylene transpiration. Si loo helo conductivity togan, waxaa lagu daaweeyay at 700 ℃ 1h in foornada korontada hoos N2 jawi. Si loo sameeyo qiimeynta korantada ee walxaha isku dhafan ee silikoon-CB, walxo isku dhafan oo silikoon-CB ah oo leh jajab tiro badan oo ah 80wt% ayaa loo isticmaalay sida walxaha firfircoon ee kaarboon madow si loogu diyaariyo anode.

(10 qayb%; Superp) sida kaari ahaan, polyacrylic acid (PAA; 10%) sida xidhe biyo diirran

Unugyada qadaadiicda CR2032 waxaa lagu soo ururiyaa sanduuqa galoofyada oo ay ka buuxaan gaaska argon, 2400 Celgard separator, lithium foil sida korantada korantada iyo electrode tixraaca, 1MLiPF6 sida polycarbonate vinyl = diethyl carbonate (EC = DEC) (1: 1 mugga). Isticmaal 10% fluorinated ethylene carbonate (FEC) sidii elektrolyt ahaan. Dhammaan unugyada waxaa lagu tijaabiyay cufnaanta hadda ee 0.05 ~ 3V at 1°C (Li=Li+).

[372 mah = g; Isticmaalka nadaamka ogaanshaha baytariga BCS805 bayooloji, ku dallaca (saarista lithium) iyo ku shubista (tuurka lithium) heerkulka qolka.
