Kulezi zinsuku lapho siphula amarekhodi okushisa aphansi, khumbula ukuthi ibhethri kusuka kuselula yakho kunganyamalala cishe ku-jiffy ngenxa yobuchwepheshe babo. Lokho kusho ukuthi, njengoba idlula ama-degree angama-15 ngaphansi kuka-zero, qaphela uma udinga ukusebenzisa iselula yakho.
Ngeke ube owokuqala ukushaja ifoni yakho ngo-100% ukuya ohambweni ngethempelesha ephansi kakhulu, futhi lapho udinga ukusebenzisa i-GPS ukufinyelela indawo okuyo, ngokuzumayo uzithola ucingo luvaliwe ngaphandle kwebhethri futhi ngaphandle kokukwazi ukuyishaja uze ume egalaji elilandelayo likaphethiloli noma esiteshini sesevisi.
Kungani ibhethri idonsa ngokushesha okungaka?
Ukuze sizwane ngokushesha, i Ubuchwepheshe bamanje be-lithium-ion bathembele ochungechungeni lwezinto ezenzeka ngamakhemikhali ukuze zisebenze. Yilawo mazinga okushisa aphansi kakhulu anciphisa ijubane noma avele "afrize" lokhu kusabela.
Eqinisweni, amanye amafoni afana ne-Samsung, ngisho ne-Galaxy Note10 +, okukhulunywe ngakho embikweni wesondlo, futhi kuhlobene nesikhathi sokushaja, ukuthi isebenza kahle kakhulu lapho izinga lokushisa liphakathi kuka-10 no-40 degrees.
Uma singena ngokuningiliziwe kumakhemikhali ahlala kumabhethri e-lithium-ion sonke esiwasebenzisayo kuma-mobiles ethu, Ukukhishwa kwebhethri kuyaqhubeka njengoba i-lithium ions ihamba ngesixazululo kusuka kolunye uhlangothi lokuphela kwebhethri, okungaba yi-anode, kolunye uhlangothi lwayo nokuthi kwaziwa njenge-cathode. Lapho ibhethri selikhishwe ngokuphelele, wonke lawo ma-ion ashumeka ku-anode.
Into ehlekisayo ngakho konke lokhu ukuthi isizathu sokuthi kungani amakhaza ayingozi asikaziwa ibhethri. Kakade ngo-2011 iqembu lonjiniyela bamabhethri labika kwi-Journal of The Electrochemical Society (iphephabhuku elikhethekile emkhakheni we-electrochemical science and technologies), ukuthi izindlela ezinomthelela ekusebenzeni okuphansi kwalolu hlobo lwebhethri azikaziwa.
Musa ukushaja ifoni yakho ngamazinga okushisa aphansi kakhulu noma usuvele "umisiwe"
Manje, uma sisesimweni sichazwe ngokuningiliziwe mayelana nokuthi wonke lawo ma-ion atholakala kanjani ohlangothini lwebhethri esilibiza ngokuthi yi-cathode, ungaze ucabange ngokuzama ukuyilayishanjengoba inqubo yokulayisha ingahle yehluleke ngokungalindelekile.
Lapha okumele sikwenze ukuthi sibe nokubekezela okuncane futhi thatha ifoni uyise endaweni noma esakhiweni lapho sinamazinga okushisa amancane kakhulu. Ngomlingo, ibhethri leselula lethu belizobuyela esimweni salo semvelo linamaphesenti afanayo enkokhiso.
UStephen J. Harris, usokhemisi eLawrence Berkeley National Laboratory, ngaphansi kwezimo ezijwayelekile zokushisa, ngokusebenzisa amandla kagesi noma ukushaja ibhethri "kungathwala" ama-ion abuyele kuma-pores ku-graphite ye-anode. Kepha uma ibhethri lithi "yiqhwa", lawo ma-ion awakwazi ukungena ku-graphite futhi aphume esixazululweni ukumboza ubuso be-graphite njenge-lithium eqinile.
Manje, uma sizama ukushaja ifoni ephathekayo ngawo lowo mzuzu, nebhethri "iqandisiwe", i- inqubo ingonakalisa ukusebenza nempilo ibhethri.
Lokho, nokuqondana kalula, lapho ibhethri le- ifoni yethu ibuyela ekushiseni okujwayelekile, "ama-ion" azobuyela endaweni yawo futhi iphesenti lomthwalo libuyela esimeni salo.
Ngakho, uma udinga iselula yakho ukuhamba ngaleyo ndlela ofuna ukuhamba ngayo ngayo yonke leyo mikhakha eneqhwa, futhi uyayidinga ukuze ukwazi ukuzibeka, cabanga kabili; Ikakhulukazi uma uhamba ezindaweni ezingaphezulu kwe-15 degrees Celsius ngaphansi kuka-zero; Ungaphuthelwa yilokhu okokufundisa ngokuthi ungayihlanza kanjani iselula yakho.
