1.1 I-Quantum Confinement kanye ne-Electronic Framework Change
(I-Nano-Silicon Powder)
I-Nano-silicon powder, eyenziwe ngezingcezu ze-silicon ezinobukhulu obuthile obalwe ngezansi 100 ama-nanometers, imele ukuguqulwa okujwayelekile ukusuka ku-silicon yenqwaba kukho kokubili izenzo ezingokoqobo kanye nensizakalo esebenzayo.
Ngenkathi i-silicon eyinqwaba iyisemiconductor ye-bandgap engaqondile ene-bandgap cishe 1.12 eV, i-nano-sizing idala imiphumela yokuboshwa kwe-quantum eshintsha ngokuyisisekelo izindawo zayo zokuhlala ze-elekthronikhi nezamehlo.
Lapho usayizi kancane izindlela noma lehla ngezansi exciton Bohr ibanga Silicon (~ 5 nm), abahlinzeki bezinsizakalo ezikhokhwayo bagcina benobunzima bendawo, okuholela ekwandeni kwe-bandgap kanye nokwethulwa kwe-photoluminescence ebonakalayo– umuzwa ontula ku-silicon enkulu.
Lokhu kuvumelana okuncike kusayizi kwenza kube nokwenzeka ukuthi i-nano-silicon ikhiphe ukukhanya kulo lonke ibanga elibonakalayo, okwenza kube yithemba elikhangayo le-silicon-based optoelectronics, lapho i-silicon evamile iyeka ukusebenza ngenxa yokungasebenzi kahle kwayo kokuhlanganisa kabusha kwemisebe.
Ngaphezu kwalokho, isilinganiso esithuthukisiwe ukusuka phezulu kuye kuvolumu ku-nanoscale sithuthukisa ukuzwela okuhlobene nendawo, ehlanganisa ukuzwela kwamakhemikhali, umsebenzi we-catalytic, kanye nokuxhumana nezinkambu ze-electromagnetic.
Le miphumela ye-quantum ayizona nje ilukuluku lezemfundo kodwa idala isisekelo sezinhlelo zokusebenza zesizukulwane esilandelayo emandleni., eqaphela, kanye ne-biomedicine.
1.2 I-Morphological Diversity kanye ne-Surface Area Chemistry
I-nano-silicon powder ingahlanganiswa kuma-morphology amaningi, kufaka phakathi ama-nanoparticles ayindilinga, ama-nanowires, nanostructures permeable, kanye namachashazi e-quantum ayikristalu, ngasinye sinikeza izinzuzo ezihlukile kuye ngohlelo oluqondiwe.
I-Crystalline nano-silicon ngokuvamile igcina uhlaka lwe-ruby cubic lwe-silicon enkulu kodwa ibonisa ukushuba okukhulu kwezinkinga ezingaphezulu kanye namabhondi alengayo., okufanele kudluliswe ukuze kusimamise ukwaziswa.
Ukusebenza kwendawo engaphezulu– ngokuvamile kutholakala nge-oxidation, i-hydrosilylation, noma i-ligand add-on– idlala indima ebalulekile ekuhlonzeni ukuphepha kwe-colloidal, ukuhlakazeka, kanye nokuhambisana no-matrics kumakhomponi noma emkhathini webhayoloji.
Njengesibonelo, I-hydrogen-terinated nano-silicon yembula ukuzwela okuphezulu futhi ijwayele ukuhlangana ne-oxidation emoyeni, kanti alkyl- noma i-polyethylene glycol (I-PEG)-izinhlayiya ezimboziwe zibonisa ukuzinza okuthuthukisiwe kanye nokuvumelana kwezinto eziphilayo ukuze kusetshenziswe i-biomedical.

Ukuba khona kongqimba lwe-oxide yomdabu (SiOₓ) endaweni eyizinhlayiyana, ngisho nangenani elincane kakhulu, kuthinta kakhulu ukuhanjiswa kukagesi, I-lithium-ion diffusion kinetics, kanye nokusabela kobuso, ikakhulukazi ezinhlelweni zebhethri.
Ukuqonda nokulawula amakhemikhali angaphezulu kuwumphumela obalulekile ekusebenziseni umthamo ogcwele we-nano-silicon ezinhlelweni ezinengqondo..
2. Izindlela Zokuhlanganisa kanye Namasu Okukhiqiza Awohlokayo
2.1 Amasu aphezulu-Phansi: Ukugaya, Etching, kanye ne-Laser Ablation
Ukwenziwa kwe-nano-silicon powder kungahlukaniswa kabanzi ngamasu aphezulu phansi naphansi phezulu, ngalinye line-scalability ehlukile, ubumsulwa, kanye nezimfanelo zokulawula i-morphological.
Amasu okuya phezulu abandakanya ukwehla ngokomzimba noma kwamakhemikhali kwe-silicon eyinqwaba ibe yizingcezu ze-nanoscale.
Ukugaya okuzungeza amandla aphezulu kuyindlela yokuhweba esetshenziswa kakhulu, lapho izingxenye ze-silicon zidlula ekugayeni okukhulu kwemishini emkhathini we-inert, kubangela micron- kuma-nano-size powders.
Ngenkathi ithengeka futhi ingakaleka, le ndlela ivame ukwethula amaphutha ekristalu, ukungcola okuvela kumithombo yezokuxhumana, kanye nokujikeleza kwe-particle dimension ebanzi, ukubiza ukuhlanzwa ngemuva kokucubungula.
Ukwehla kwe-Magnesiothermic ye-silica (SIO LESIBILI) okulandelwa ukucwiliswa kwe-asidi kuyindlela eyengeziwe enokucutshungulwa, ikakhulukazi lapho kusetshenziswa izinsiza ze-silica ezitholakala kudoti nje kuphela njengamakhoba erayisi noma ama-diatom, usebenzisa indlela ehlala njalo eya ku-nano-silicon.
Ukukhishwa kwe-laser kanye ne-plasma etching esabelayo kuyindlela enembe kakhulu yokuya phansi, esebenza kahle ekukhiqizeni i-nano-silicon ehlanzekile ene-crystallinity elawulwayo, kodwa ngentengo ephezulu kanye nokuncishiswa kokusebenza.

I-silicon inikeza ikhono elithile lezemfundo lika-~ 3579 mAh/g esekelwe ekwakhekeni kwe-Li ₁₅ Si Four, okucishe kube 10 izikhathi eziphakeme kunalezo ze-graphite evamile (372 mAh/g).
Nokho, ukwanda kwevolumu enkulu (~ 300%) ngesikhathi i-lithiation ibangela ukubola kwezinhlayiyana, ukulahlekelwa ukuthintana kukagesi, kanye ne-interphase eqinile ye-electrolyte eqhubekayo (BE) ukwakheka, okuholela ekushintsheni kombala okusheshayo.
Nanostructuring reduces these problems by shortening lithium diffusion courses, suiting strain more effectively, and decreasing crack probability.
Nano-silicon in the kind of nanoparticles, permeable frameworks, or yolk-shell structures makes it possible for relatively easy to fix cycling with boosted Coulombic efficiency and cycle life.
Commercial battery modern technologies now integrate nano-silicon blends (isib., silicon-carbon composites) in anodes to enhance power thickness in customer electronic devices, electric automobiles, and grid storage systems.
3.2 Possible in Sodium-Ion, Potassium-Ion, and Solid-State Batteries
