Indlela yokubiza iibhetri ezintsha? Yeyiphi indlela yokutshaja ukwenza ibhetri yomelele ngakumbi?

● Ukuhlawula ngokuchanekileyo ibhetri entsha ihlala inephutha elinjalo, kwaye isithuthi sombane esandula kuthengwa kufuneka siphuphume kwiiyure ze-12, kwaye ibhetri ye-lithium-ion ingasebenza ngamaxesha e-3. Enyanisweni, oku akuyi kwenza kuphela ukusebenza kwebhetri ye-lithium ion ngcono, kodwa kwakhona kukhawulezisa umonakalo weebhetri ze-lithium-ion. Ngokuphathelele ibhetri entsha ye-lithium-ion, musa iindlela ezikhethekileyo, nje ngokuba i-3-5 intlawulo eqhelekileyo kunye nokukhutshwa, ibhetri ye-lithium-ion ingasebenza, kwaye umthamo webhetri oqhelekileyo ubuyiselwe.

● Amandla aphantsi kakhulu, kwaye abasebenzisi be-intanethi abaninzi bahlawuliswa ngexesha. Enyanisweni, oku kwakhona kuyimpazamo. Ukuba ngexesha lokuqhuba, isithuthi sombane sibonise ukuba ukusetyenziswa kombane kuphantsi kakhulu.

Ukuba ayikahlawuliswa, ibhetri ye-lithium-ion inokubangela ukuba i-voltage iphantsi kakhulu ngenxa yokukhutshwa ngokugqithiseleyo, ngoko ke yonakalise ibhetri ye-lithium-ion. Ubomi, ngoko ke ukutshaja kufuneka kuhlawulwe ngexesha xa ucelwa. Khetha iprosesa eqhelekileyo, kukho uphawu lwemveliso yokuthotyelwa, nikela ingqalelo kumhla wokucubungula ibhetri ye-lithium-ion.

Uninzi lweebhetri ze-lithium-ion zamahhala ezintathu, ukwenzela ukugcina iindleko, kukho ingxaki ngomgangatho. Thintela iindleko ezingenanto ekugcinweni ixesha elide, kodwa kwakhona uthintele i-overcharge. Thintela ukuba sesichengeni kunye nemvula.

Zama ukugcina izithuthi zombane kwindawo ekhethekileyo yokupaka ukwenzela ukuthutha i-lithium ion, i-interface ayinayo kuphela iqondo eliphezulu lokufakelwa kwe-electron, kodwa kunye ne-ionic conductivity, ebaluleke kakhulu. Ukongeza, i-interface ayikho i-ultra-thin ukukhusela ubuninzi bamandla ebhetri. Ukuze kuhlangatyezwane nale mingeni, iqela lisebenzisana neBrookhaven National Laboratory (BrookhavennationalLab) kunye nabalingane baseCityUniversityofnewyork.

I-boron nam boron nam boron nam boron namide (BN) ifilimu ye-nano ediphozithiweyo ifakwe njengomaleko okhuselayo, kwaye uqhagamshelwano lombane phakathi kwentsimbi ye-lithium kunye ne-ionic conductor (i-electrolyte eqinile) yahlulwe, kwaye ixabiso elincinci le-polymer okanye i-electrolyte engamanzi ingena kwi-electrode / electrolytic interface. Khetha i-BN njengoluhlu olukhuselayo ngenxa yokuba izinzile nge-lithium yensimbi kwi-chemistry kunye noomatshini, ukubonelela ngezinga eliphezulu lokufakelwa kwe-elektroniki. Ukuyila i-boron nitride layer ineziphene zangaphakathi, kwaye i-lithium ion inokudlula kuyo, iyenze ibe ngumahluli obalaseleyo.
