Izinzuzo Zamabhethri Asekelwe Ku-Nanotechnology
Ubuchwepheshe bamandla buthuthuke ngokushesha emashumini eminyaka amuva nje, buqhutshwa yisidingo esikhulayo samadivayisi aphathekayo, izimoto zikagesi, kanye nezinhlelo zokugcina amandla avuselelekayo. Phakathi kwesidingo samabhethri ahlala isikhathi eside, ashaja ngokushesha, aphephile, futhi anobungani nemvelo, enye indlela idonsele ukunaka okukhulu: amabhethri asekelwe kubuchwepheshe be-nano. Kalula nje, ubuchwepheshe be-nano buwubunjiniyela bezinto ezisetshenziswa esikalini se-nanometer (ingxenye eyodwa kweziyizigidigidi zemitha), lapho izakhiwo zikagesi, zamakhemikhali, kanye nezemishini zezinto zingashintsha kakhulu uma kuqhathaniswa nesimo sazo "esikhulu". Ukusetshenziswa kobuchwepheshe be-nano kumabhethri kuvula amathuba okuthuthukiswa kokusebenza okunzima ukukufeza ngezinto ezivamile.
Okulandelayo yizinzuzo eziyinhloko zamabhethri asekelwe ku-nanotechnology, kanye nezizathu zesayensi kanye nomthelela wawo empilweni yansuku zonke.
1. Amandla Aphezulu kanye Nobuningi Bamandla
Enye yezinzuzo ezibaluleke kakhulu ze-nanotechnology yikhono layo lokukhulisa indawo esebenzayo yezinto ze-electrode. Emabhethri, ukugcinwa kwamandla kanye nokusabela kokukhululwa kwenzeka ezindaweni nasezinhlakeni zezinto. Lapho izinto ze-electrode zenziwa isakhiwo se-nano—isibonelo, i-nanoparticle, i-nanowire, noma i-nanosheet—indawo etholakalayo yobuso iyanda kakhulu.
Ngenxa yalokho, amabhethri angagcina ukushaja okwengeziwe ngosayizi ofanayo. Lokhu kusho ukuthi amandla amaningi anamandla, okuvumela amadivayisi afana namaselula, ama-laptop, ama-drone, kanye nezimoto zikagesi ukuthi zisebenze isikhathi eside ngaphandle kokukhulisa usayizi webhethri kakhulu. Uma kukhulunywa ngezimoto zikagesi, amandla aphezulu angabangela ukuthi ibhethri libe nebanga elide noma isisindo esilula.
2. Ukushaja Okusheshayo
Isikhathi sokushaja ibhethri sisalokhu singenye yezikhalazo ezinkulu phakathi kwabasebenzisi bamadivayisi aphathekayo nezimoto zikagesi. I-nanotechnology isiza ukubhekana nale nkinga ngezindlela ezimbili eziyinhloko: ukunciphisa izindlela zokusabalalisa ama-ion kanye nokwandisa ukuhanjiswa kwezinto.
Ku-nanoscale, ama-ion (isb., ama-ion e-lithium) anamabanga amafushane okuhamba ukuze angene futhi aphume ezakhiweni ze-electrode. Ngaphezu kwalokho, izinto ezisekelwe ku-nano zingaklanywa ukuze zibe ne-porosity esebenza kahle kanye nezindlela zokuthutha ama-ion. Umphumela uba ibhethri elingaphatha amaza okushaja aphezulu ngaphandle kokushisa ngokweqile noma ukwehlisa ukusebenza, ngaleyo ndlela linciphise izikhathi zokushaja.
Ukube lobu buchwepheshe bebusetshenziswa kabanzi, cabanga ngebhethri lemoto kagesi elishajwayo elingalinganisa isipiliyoni "sesiteshi sikaphethiloli": ngokushesha, okulula kakhudlwana, futhi nesikhathi sokulinda esincane.
3. Impilo Yomjikelezo Omude
Ibhethri alilinganiswa nje kuphela ngomthamo walo wokuqala, kodwa futhi nokuthi lingalondoloza isikhathi esingakanani ukusebenza kwalo ngemva kwamakhulu noma izinkulungwane zemijikelezo yokushaja. Amabhethri amaningi avamile abhekana nokuwohloka kokusebenza ngoba izinto ze-electrode ziyanda futhi zinciphe njengoba ama-ion engena futhi ephuma (ukuhlangana), okubangela ukuqhekeka okuncane, ukuwohloka kwesakhiwo, noma ukulahlekelwa ukuxhumana kukagesi.
Izakhiwo ezincane zingasiza ekunciphiseni le miphumela. Isibonelo, ama-electrode e-nanowire noma ama-electrode anezimbobo ezincane angabekezelela kakhulu izinguquko zevolumu, anciphise umonakalo womshini. Ngaphezu kwalokho, i-nano-coatings ingavimbela ukusabela okungekuhle okulimaza izinto ze-electrode. Le nhlanganisela inamandla okukhiqiza amabhethri anesikhathi eside sokuphila, okusho izindleko zobunikazi eziphansi kanye nokulahlekelwa yibhethri okuncishisiwe.
4. Ukuvikeleka Okungcono
Ukuphepha kubalulekile, ikakhulukazi ngemuva kwezigameko eziningi zokushisa ngokweqile, ukwanda, ngisho nokubamba umlilo. Kumabhethri e-lithium-ion, ingozi eyodwa ukwakheka kwama-dendrites (izakhiwo ezifana nenaliti) ku-anode, engangena esihlukanisi futhi ibangele i-internal short circuit.
I-nanotechnology ingasiza ekwakheni izinto ezivimbela ukwakheka kwe-dendrite noma zenze izakhiwo ze-electrode ziqine kakhudlwana. Ngaphezu kwalokho, ukuthuthukiswa kwama-electrolyte asekelwe ku-nanocomposite noma abahlukanisi abaqiniswe yi-nanomaterial kungathuthukisa ukumelana nokushisa futhi kunciphise amathuba okuvuza kanye nokusabela okungalawuleki.
Nakuba lokhu kungasho ukuthi wonke ama-nanobatteries aphephile ngokuzenzakalelayo, ucwaningo lusikisela ukuthi i-nanotechnology inikeza amathuluzi amasha okulawula izici ezibangela ukwehluleka kwebhethri.
5. Ukusebenza Okuzinzile Kakhulu Ezimweni Ezimbi Kakhulu
Amabhethri avame ukubhekana nokusebenza okunciphile emazingeni okushisa abandayo noma ashisa kakhulu. Emazingeni okushisa aphansi, ukunyakaza kwama-ion kuyehla; emazingeni okushisa aphezulu, ukusabela okuseceleni kuyanda futhi kusheshise ukuwohloka. Izinto ezisetshenziswayo zingaklanywa ukuze kwandiswe ukuhanjiswa kwama-ion futhi kube lula ukuthuthwa kwawo, okuvumela amabhethri ukuthi agcine ukusebenza kwawo ebangeni elibanzi lokushisa.
Le nzuzo ibalulekile ekusetshenzisweni kwangaphandle, ekusetshenzisweni kwezimboni, ezimotweni ezisebenza ezindaweni ezihlukene zezulu, kanye namadivayisi ezindaweni ezikude ezibhekene nezimo zemvelo ezingaphansi kwezinga elifanele.
6. Amathuba Okusebenzisa Izinto Ezingashintshi Ezingaguquki
I-nanotechnology ayigcini nje ngokwenza amabhethri "abe namandla kakhulu," kodwa futhi ivula amathuba okufaka esikhundleni sezinto ezibizayo noma eziyinkinga kuchungechunge lokuhlinzeka. Isibonelo, ucwaningo lwe-nanotechnology luvumela ubunjiniyela bezinto ze-electrode ezivela emithonjeni eminingi noma elula ukuyicubungula, ngenkathi kugcinwa ukusebenza.
Ngaphezu kwalokho, ukusetshenziswa kwezinto ezithile ze-nanomaterial kungandisa ukusebenza kahle kokusetshenziswa kwezinto ezisebenzayo, ngaleyo ndlela kuncishiswe isidingo sezinto zokusetshenziswa ngomthamo webhethri ngalinye. Ezingeni lezimboni, lokhu kunganciphisa ingcindezi ekukhishweni kwezinsiza futhi kufake isandla ekusimeni.
7. Usayizi Omncane Kakhulu kanye Nomklamo Oguquguqukayo Kakhulu
Ngenxa yokuthi izakhiwo zezinto eziku-nanoscale zingalawulwa, abakhiqizi banamandla okudala amabhethri anezinhlobo eziningi zezimo nezakhiwo. I-nanotechnology isekela ukuthuthukiswa kwama-electrode amancane, amabhethri aguquguqukayo, ngisho namabhethri angahlanganiswa nezakhiwo zedivayisi (isibonelo, kumadivayisi agqokwayo noma izinzwa ze-Internet of Things).
Lo mklamo oguquguqukayo uzoba usizo olukhulu kumadivayisi esikhathi esizayo adinga imithombo yamandla elula, emincane, nevumelana nesimo.
