Isishwankathelo

Ngengozi engaphezulu ebangelwa yibhetri ye-lithium-ion iyenzeka, Abantu banenkxalabo malunga nokubaleka kwebhetri ye-thermal, njengoko i-thermal run away eyenzeka kwiseli enye inokusasaza ubushushu kwezinye iiseli, ezikhokelela ekuvaleni kwayo yonke inkqubo yebhetri.

Ngokwemveli siya kubangela ukubaleka kwe-thermal ngokufudumeza, ukukhonkotha okanye ukutshaja ngexesha lovavanyo. Nangona kunjalo, ezi ndlela azinakulawula ukubaleka kwe-thermal kwiseli echaziweyo, kwaye azinakuphunyezwa ngokulula ngexesha lovavanyo lweenkqubo zebhetri. Kutshanje abantu baphuhlisa indlela entsha yokuqalisa ukubaleka kwe-thermal. Uvavanyo lokusasaza kwi-IEC 62619 entsha: 2022 ngumzekelo, kwaye kuqikelelwa ukuba le ndlela iya kusetyenziswa ngokubanzi kwixesha elizayo. Eli nqaku lenzelwe ukwazisa ezinye iindlela ezintsha eziphantsi kophando.

Imitha yeLaser:

Imitha yeLaser kukufudumeza indawo encinci ene-laser yamandla aphezulu. Ubushushu buya kuqhutywa ngaphakathi kwizinto eziphathekayo. Imitha yeLaser isetyenziswa kakhulu kwiindawo zokulungisa izinto, njengokuwelda, ukudibanisa kunye nokusika. Ngokuqhelekileyo kukho iintlobo ze-laser ngolu hlobo lulandelayo:

• CO₂laser: carbon dioxide molecular gas laser
• I-laser ye-semiconductor: I-laser ye-Diode eyenziwe nge-GaAs okanye i-CdS
• I-laser ye-YAG: I-sodium laser eyenziwe ngegarnet ye-yttrium aluminiyam
• I-Optical fiber: i-laser eyenziwe ngefiber yeglasi enento enqabileyo yomhlaba

Abanye abaphandi basebenzisa i-laser ye-40W, ubude be-wave ye-1000nm kunye ne-1mm ye-diameter ukuvavanya kwiiseli ezahlukeneyo.

Ukuba ne-CT scan kwiseli engavuswanga, kunokufunyanwa ukuba akukho mpembelelo yesakhiwo ngaphandle komngxuma ongaphezulu. Kuthetha ukuba i-laser iyalathisa, kwaye inamandla amakhulu, kwaye indawo yokufudumeza ichanekile. Ngoko i-laser yindlela efanelekileyo yokuvavanya. Sinokulawula ukuguquguquka, kwaye sibale igalelo kunye nemveliso yamandla ngokuchanekileyo. Ngeli xesha i-laser ineenzuzo zokufudumeza kunye ne-pinning, njengokufudumeza okukhawulezayo, kunye nokulawulwa ngakumbi. I-Laser ineenzuzo ezininzi ezifana:

• Inokubangela ukubaleka kwe-thermal kwaye ayizi shushu kwiiseli zabamelwane. Oku kulungile ekusebenzeni koqhagamshelwano lwe-thermal

• Inokuvuselela ukunqongophala kwangaphakathi

• Ingafaka amandla amancinci kunye nobushushu ngexesha elifutshane ukwenza ukubaleka kwe-thermal, okwenza uvavanyo lube phantsi kolawulo.

Impendulo ye-Thermite:

Ukusabela kwe-Thermite kukwenza i-Aluminiyam ukuba isabele nge-oxide yentsimbi kwiqondo lobushushu eliphezulu, kwaye i-aluminiyam iya kutshintshela kwi-aluminiyam oxide. Njengoko i-enthalpy yokwenziwa kwe-aluminium oxide iphantsi kakhulu (-1645kJ / mol), ngoko iya kuvelisa ubushushu obuninzi. Isixhobo se-thermite siyafumaneka, kwaye ifomula eyahlukileyo inokuvelisa inani elahlukileyo lobushushu. Abaphandi ke ngoko baqala ukuvavanya nge-10Ah pouch ene-thermite.

I-Thermite inokwenza ngokulula ukubaleka kwe-thermal, kodwa igalelo le-thermal akulula ukulawula. Abaphandi bafuna ukuyila i-thermal reactor evaliweyo kwaye ikwazi ukubukisa ubushushu.

Isibane seQuartz esinamandla aphezulu:

Ithiyori: Beka isibane se-quartz samandla aphezulu phantsi kweseli, kwaye uhlukanise iseli kunye nesibane ngepleyiti. Ipleyiti kufuneka igrunjwe ngomngxuma, ukuze kuqinisekiswe ukuziphatha kwamandla.

Uvavanyo lubonisa ukuba ludinga amandla aphezulu kakhulu kunye nexesha elide ukuqalisa ukubaleka kwe-thermal, kwaye i-thermal ihlelwe ngokulinganayo. Isizathu sinokuba isibane sequartz asikokukhanya okuya ngqo, kwaye ilahleko enkulu yobushushu ibangela ukuba kungabi lula ukubaleka ubushushu ngokuchanekileyo. Okwangoku igalelo lamandla alichanekanga. Olona vavanyo lufanelekileyo lokubaleka kwe-thermal kukulawula amandla axhokonxayo kunye nexabiso elisezantsi lentsalela yegalelo, ukunciphisa impembelelo kwiziphumo zovavanyo. Ke ngoko sinokufikelela kwisigqibo sokuba isibane sequartz asiloncedo okwangoku.

Isiphelo:

Ukuthelekisa indlela yendabuko yokubangela ukubaleka kwe-thermal cell (njengokufudumala, ukutshaja ngokugqithiseleyo kunye nokungena), ukusabalalisa kwe-laser yindlela esebenzayo, kunye nommandla omncinci wokufudumeza, amandla aphantsi okufakwayo kunye nexesha elifutshane lokukhupha. Oku kugalelwe kwigalelo eliphezulu elisebenzayo lamandla kwindawo enyiniweyo. Le ndlela iye yaziswa yi-IEC. Sinokulindela ukuba amazwe amaninzi aya kuyithathela ingqalelo le ndlela. Nangona kunjalo iphakamisa imfuneko ephezulu kwizixhobo ze-laser. Ifuna umthombo welaser ofanelekileyo kunye nezixhobo zobungqina bemitha. Okwangoku akukho matyala aneleyo ovavanyo lokubaleka kwe-thermal, le ndlela isafuneka ukuqinisekiswa.
