Ibhethri ye-lipo eguquguqukayo

Lokhu kutholakala kwenze abanye abacwaningi basungula izinhlobo ezintsha zamabhethri e-Li-ion aguquguqukayo asebenzisa izinto ezingajwayelekile njengama-polymer anwebekayo noketshezi oluphilayo esikhundleni sama-electrolyte anguketshezi oluvuthayo (into evumela ama-ion ukuthi ahambe phakathi kwama-electrode amabili).Izinkampani eziningi zenze imikhiqizo esekelwe kulezi zinsiza ezintsha, futhi lesi sihloko sizohlola izinhlobo ezimbili zamabhethri ashintshekayo aphinde ashajwe atholakalela ukusetshenziselwa ukuthengisa.

Uhlobo lokuqala lusebenzisa i-electrolyte evamile kodwa enesihlukanisi esiyinhlanganisela ye-polymer esikhundleni se-polyethylene enezimbobo evamile noma impahla ye-polypropylene. Lokhu kuvumela ukuthi igotshwe noma ibunjwe ibe amafomu ahlukene ngaphandle kokuphuka. Isibonelo, abakwaSamsung basanda kumemezela ukuthi sebethuthukise ibhethri elikwazi ukugcina ukuma kwalo noma ligoqwe phakathi. Lawa mabhethri abiza kakhulu kunawavamile kodwa angahlala isikhathi eside ngenxa yokuthi kukhona ukumelana okuncane kwangaphakathi okuvela kuma-electrode aminyene nezihlukanisi. Kodwa-ke, enye into ebuyisela emuva ukuminyana kwamandla aphansi uma kuqhathaniswa: Angagcina kuphela amandla amaningi njengebhethri ye-Li-ion enosayizi ofanayo futhi awakwazi ukushajwa kabusha ngokushesha.

Lolu hlobo lwebhethri ye-Li-ion okwamanje lusetshenziswa Kuzinzwa Ezigqokekayo ukuze kuqashwe izimpawu ezibalulekile zomzimba, kodwa lungaphinda luhlanganiswe nempahla ehlakaniphile. Isibonelo, i-Cute Circuit yenza ingubo elandelela amazinga okungcoliswa komoya futhi ixwayise abasebenzisi ngesibonisi se-LED ngemuva uma kunamaleveli aphezulu endaweni eseduze yomuntu oyifakile. Ukusebenzisa lolu hlobo lwebhethri eliguquguqukayo kungenza kube lula ukuhlanganisa izinzwa ngokuqondile ezingutsheni ngaphandle kokwengeza inqwaba noma ukungakhululeki.

Amabhethri e-lithium asetshenziswa kakhulu emikhiqizweni yabathengi efana nomakhalekhukhwini namalaptop, kodwa ukuthuthukiswa kwamandla ayo (amandla, isisindo) kungaholela ekusetshenzisweni okunenzuzo okufana nemishini yezokwelapha nezimoto zikagesi. Njengoba amabhethri amaningi esebenzisa ikesi eqinile enama-electrode afakwe ngaphakathi, kube nocwaningo olubanzi lokuthi ingabe ibhethri eliguquguqukayo lingathuthukiswa elingavumela izimo ezihlukene kanye namadivayisi angaba namandla kakhulu.

Izimoto zikagesi ezitholakalayo njengamanje zinebanga elilinganiselwe ngenxa yokuminyana kwamandla amancane amabhethri abangelwa ukusebenzisa amakhaseji aqinile. Amabhethri aguqukayo angabuye agqokwe ezingutsheni noma asongwe endaweni engajwayelekile, okuvula amathuba amasha obuchwepheshe obugqokekayo. Ukwengeza, ukuguquguquka okukhulu kusho ukuthi amabhethri angagcinwa ezindaweni eziqinile futhi ahambisane nokuma okungajwayelekile; lokhu kungase kubangele amabhethri anosayizi omncane kunalawo anesilinganiso esifanayo esivamile.

Ezenye:

Ibhethri eliguquguqukayo elisebenzisa ucwecwe lwensimbi esikhundleni sama-electrode aqinile lakhiwe abacwaningi baseYunivesithi yaseCalifornia, eBerkeley. Idizayini inesithembiso sokusebenza okungcono kakhulu kunamadivayisi amanje ngenxa yokuthi yenziwe ngamashidi amancane amancane anqwabelene, okuphumela ekuminyaneni okukhulu kwamandla kuyilapho ehlala eguquguquka ngokuphelele. Imizamo yangaphambilini yokusebenzisa ezinye izinto ezifana ne-graphene ayiphumelelanga ngenxa yokuba ntekenteke kwalezi zakhiwo kanye nokuntuleka kwazo kokukaleka. Kodwa-ke, umklamo omusha we-foil wensimbi ulandela isakhiwo esifanayo kumabhethri e-lithium-ion ezentengiselwano futhi uvumela la mayunithi ukuthi akhiqizwe esikalini sezimboni ngaphandle kobunzima.

Izicelo:

Amabhethri e-lipo aguquguqukayo angaholela ezinsizakalweni zezokwelapha ezigqokwa kalula emzimbeni, izimoto zikagesi ezinebanga elikhulu lokushayela, ubuchwepheshe obugqokekayo obungaphazamisi ukunyakaza, nezinye izinhlelo zokusebenza ezisebenzisa ngokunenzuzo lokhu kuguquguquka okukhulayo.

Isiphetho:

Ucwaningo eNyuvesi yaseCalifornia Berkeley lukhiqize ibhethri eliguquguqukayo elakhiwe ngamashidi ensimbi apakishiwe ngaphandle kokusebenzisa izinto ezintekenteke zegraphene. Lo mklamo unikeza ukuminyana kwamandla okukhuphukile kunamadivayisi amanje kuyilapho ehlala eguquguquka ngokuphelele. Amabhethri e-lipo aguqukayo nawo anokusebenza okungenzeka ezimotweni zikagesi, ubuchwepheshe obugqokekayo, nezinye izindawo lapho ukuguquguquka okuthuthukisiwe kunenzuzo.
