- I-silicon-carbon ithatha indawo ye-graphite ku-anode ukuze igcine ama-ion e-lithium afinyelela ku-10.
- Ivumela ukudalwa kwamadivayisi amancane kakhulu noma ukwanda kwamandla aphakathi kuka-20% no-40%.
- Zimelana nemithwalo esheshayo kakhulu futhi azinawo umswakama ngenxa yokuqina okuhlinzekwa yi-carbon matrix.
Sekuyisikhathi eside sijwayele iqiniso lokuthi uma sifuna amafoni ethu ahlale isikhathi eside, kufanele sibekezelele idivayisi ebanzi futhi esindayo. Amabhethri e-lithium-ion abelokhu eyindinganiso ephelele cishe iminyaka engamashumi amathathu, kodwa iqiniso liwukuthi asevele efinyelela imikhawulo yawo yamakhemikhali , okusiphoqa ukuthi sikhethe njalo phakathi komklamo omuhle kanye nokuphila kwebhethri langempela.
Ngenhlanhla, imithetho yomdlalo iyashintsha ngenxa yokwanda kwe-silicon-carbon. Akuyona isimangaliso esenzekile, kodwa kunalokho ushintsho ekwakhiweni kwe-anode, okuvumela amadivayisi amancane ngokumangazayo, njengamanye amafoni akamuva asongekayo, ukuthi afake amakhono ayengacatshangwa ngaphambili ngaphandle kokuguqula ifoni ibe yizitini.
Buyini ngempela lobu buchwepheshe be-silicon-carbon?
Ukuze siqonde lokhu ngaphandle kokuba yinkimbinkimbi kakhulu, sidinga ukubheka i-anode, okuyi-terminal engemihle yebhethri. Ngenkathi amaseli e-lithium endabuko esebenzisa i-graphite (i-carbon emsulwa), lawa mabhethri amasha asebenzisa ingxube ye-silicon ne-carbon eyakhiwe ngendlela encane . I-Silicon iyinkanyezi yangempela lapha, njengoba isebenza njenge-supermaterial ekwazi ukugcina inani elikhulu lamandla.
Eqinisweni, i-silicon ingagcina ama-ion e-lithium aphindwe kayishumi ngegremu kune-graphite evamile. Ngokwezibalo, lokhu kusho ukusuka cishe ku-370 mAh/g nge-graphite kuya ku-4.200 mAh/g emangalisayo. Lokhu kusho ukugcina amandla amaningi kakhulu endaweni efanayo ebonakalayo, okuholela ekukhuleni kwebhethri ngo-20% kuya ku-40% ngaphandle kokushintsha usayizi wengxenye.
Inkinga yokwanda kanye nesixazululo sekhabhoni
Uma i-silicon inhle kangaka, kungani singayisebenzisanga njalo? Nokho, ngoba inephutha elikhulu: "iyanwebeka kakhulu." Uma ishajwa, i-silicon ivame ukwanda futhi inciphe ngo-300% noma u-400%, okungenza isakhiwo siqhekeke futhi idivayisi iyeke ukusebenza ngemva kwemijikelezo embalwa kakhulu.
Yilapho ikhabhoni ingena khona. Esikhundleni sokusebenzisa i-silicon emsulwa, ama-carbon nanocages adalwa ukuze ahlanganise izinhlayiya ze-silicon. Ikhabhoni isebenza njenge- buffer yesakhiwo , ivumela i-silicon ukuthi yande futhi inciphe ngaphakathi ngaphandle kokulimaza ibhethri. Ngenxa yalokhu bunjiniyela, ukuzinza nokuqina okufana ne-graphite kuye kwafinyelelwa, kumelana nemijikelezo yokushaja ephakathi kuka-800 no-1.000 ngenkathi kugcinwa iningi lamandla ayo.
Izinzuzo zangempela kune-lithium evamile
Umthelela walolu shintsho mkhulu kakhulu, ikakhulukazi ezindaweni ezintathu ezibalulekile:
- Ukuminyana kwamandla: Manje kungenzeka ukufaka amabhethri angu-6.000 mAh lapho ngaphambili kwakungena khona ama-4.500 mAh kuphela. Lokhu kuvumela ukwenziwa kwamafoni amancane kakhulu (cishe ama-7 mm noma ngaphansi) angafi phakathi nosuku.
- Ukushaja okushesha kakhulu: I-Silicon yenza kube lula ukunyakaza kwama-ion ukungena nokuphuma kalula. Lokhu kuyivumela ukuthi imelane ubuningi bamanje obuphezuluukufeza ukushaja okugcwele ngemizuzu embalwa ngokunciphisa ukuwohloka kwesikhathi eside.
- Ukusimama: I-silicon iyinto eningi futhi engenabo ubuthi, enciphisa umonakalo wemvelo wokukhiqiza futhi ikhuthaze ukuvuselelwa kwamaseli esikhathini esizayo
Izicelo emakethe yamanje
Nakuba kungakabi yinto evamile eNtshonalanga, abakhiqizi baseShayina sebevele besebenzisa lobu buchwepheshe kabanzi. Amamodeli afana ne-Xiaomi 17 noma i-Honor Magic V3 ayizibonelo ezicacile zendlela yokufeza umklamo omncane kakhulu ngenkathi ugcina ibhethri elikhulu. Ngisho nemikhiqizo efana ne-Oppo yethule amadivayisi anamandla angu-7.000 mAh ngemizimba emincane kakhulu.
Kodwa lokhu akukhona nje ngemali. Imboni yezimoto zikagesi inentshisekelo enkulu, nezinkampani ezifana neTesla, iPorsche, neMercedes-Benz ezihlanganisa lawa maseli ukuze zifinyelele ibanga elikhulu emgwaqweni ngaphandle kokwengeza isisindo ku-chassis, into ebalulekile ekusebenzeni kahle kwezimoto.
Amathiphu okwandisa impilo yebhethri lakho
Khumbula ukuthi, ngisho nangentuthuko yezobuchwepheshe, i-chemistry yebhethri isalokhu ibucayi. Ukuze noma yiliphi ibhethri le-lithium noma le-silicon-carbon lihlale isikhathi eside, kungcono ukugcina ishaja iphakathi kuka- 20% no-80% , ukugwema ukuphelelwa ngokuphelele noma ukushaja okungaguquki okungu-100%. Kubalulekile futhi ukugwema amazinga okushisa aphezulu, njengoba ukushisa okukhulu kuyisitha esikhulu sebhethri .
Amanye amaqhinga awusizo afaka phakathi ukwehlisa ukukhanya kwesikrini, ukuvala izinhlelo zokusebenza ezisebenzisa izinsiza ngemuva, kanye nokusebenzisa njalo ishaja yokuqala yomenzi ukuze ugweme ukukhuphuka kwamandla kagesi okungadingekile okungacindezela ibhethri.
