Tare da ƙarin haɗari da batirin lithium-ion ke haifarwa ya faru, mutane sun fi damuwa da yanayin zafin baturi yana gudu, saboda gudun zafin zafi da ke faruwa a cikin tantanin halitta na iya yada zafi zuwa wasu sel, wanda ke haifar da rufe dukkan tsarin baturi.

A al'ada za mu haifar da zafin zafi ta hanyar dumama, pinning ko fiye da caji yayin gwaji. Koyaya, waɗannan hanyoyin ba za su iya sarrafa guduwar zafi a cikin takamaiman tantanin halitta ba, kuma ba za a iya aiwatar da su cikin sauƙi yayin gwaje-gwajen na'urorin baturi ba. Kwanan nan mutane suna haɓaka sabuwar hanya don haifar da guduwar zafi. Gwajin Yadawa a cikin sabon IEC 62619: 2022 misali ne, kuma an kiyasta cewa wannan hanyar za ta kasance mai fa'ida a nan gaba. Wannan labarin shine don gabatar da wasu sababbin hanyoyin da ake bincike.

Radiation Laser:

Laser radiation shine don dumama ƙaramin yanki tare da bugun bugun laser mai ƙarfi. Za a gudanar da zafi a cikin kayan. Laser radiation ana amfani da ko'ina a wuraren sarrafa kayan, kamar walda, haɗawa da yanke. Yawanci akwai nau'ikan Laser kamar haka:

• CO₂Laser: carbon dioxide kwayoyin gas Laser
• Laser Semiconductor: Laser Diode wanda aka yi da GaAs ko CdS
• YAG Laser: Laser sodium da aka yi da yttrium aluminum garnet
• Fiber na gani: Laser da aka yi da fiber gilashi tare da ƙarancin ƙasa

Wasu masu bincike suna amfani da Laser na 40W, tsayin igiyoyin 1000nm da diamita 1mm don gwadawa akan sel daban-daban.

Samun CT scan akan tantanin da ba a kunna ba, ana iya gano cewa babu wani tasiri na tsari sai ga rami a saman. Yana nufin Laser ne shugabanci, kuma high-power, da dumama yankin ne daidai. Saboda haka Laser hanya ce mai kyau don gwaji. Za mu iya sarrafa ma'auni, kuma mu lissafta shigarwar da makamashin fitarwa daidai. A halin yanzu Laser yana da abũbuwan amfãni na dumama da pinning, kamar sauri dumama, kuma mafi controllable. Laser yana da ƙarin fa'idodi kamar:

• Yana iya haifar da guduwar zafi kuma ba zai dumama sel makwabta ba. Wannan yana da kyau don aikin sadarwar thermal

• Yana iya tayar da ƙarancin ciki

• Yana iya shigar da ƙarancin kuzari da zafi cikin ɗan gajeren lokaci don haifar da guduwar zafi, wanda ke sa gwajin ya kasance ƙarƙashin iko sosai.

Ra'ayin Thermite:

Halin zafin jiki shine yin Aluminum don amsawa tare da oxide ƙarfe a cikin babban zafin jiki, kuma aluminum zai canza zuwa cikin aluminum oxide. Kamar yadda enthalpy na samuwar aluminum oxide yana da ƙasa sosai (-1645kJ / mol), saboda haka zai haifar da zafi mai yawa. Abun thermite yana samuwa sosai, kuma tsari daban-daban na iya haifar da adadin zafi daban-daban. Don haka masu bincike sun fara gwaji tare da jakar 10Ah tare da thermite.

Thermite na iya jawo guduwar zafi cikin sauƙi, amma shigarwar thermal ba ta da sauƙin sarrafawa. Masu bincike suna neman su ƙirƙira na'urar sarrafa zafin jiki wanda aka rufe kuma yana iya tattara zafi.

Fitilar Quartz mai ƙarfi:

Ka'idar: Sanya fitilar quartz mai ƙarfi a ƙarƙashin tantanin halitta, kuma raba tantanin halitta da fitilar tare da faranti. Dole ne a haƙa farantin tare da rami, don tabbatar da tafiyar da makamashi.

Gwajin ya nuna cewa yana buƙatar ƙarfi mai ƙarfi da kuma dogon lokaci don haifar da guduwar thermal, kuma thermal ba shi da iyaka. Dalili na iya kasancewa hasken quartz ba haske ne na jagora ba, kuma yawan asarar zafi yana sa shi da wuya ya haifar da guduwar thermal daidai. A halin yanzu shigar da makamashi ba daidai ba ne. Madaidaicin gwajin gudu na thermal shine don sarrafa kuzarin da ke jawowa da ƙananan ƙimar shigar da ragi, don rage tasirin tasirin sakamako. Don haka zamu iya zana ƙarshe cewa fitilar quartz ba ta da amfani a yanzu.

Ƙarshe:

Idan aka kwatanta da hanyar gargajiya na haifar da runaway cell thermal (kamar dumama, cajin da yawa da shiga ciki), yaduwar Laser hanya ce mafi inganci, tare da ƙaramin yanki mai dumama, ƙarancin shigar da kuzari da ɗan gajeren lokacin faɗakarwa. Wannan yana ba da gudummawa ga ingantaccen shigarwar makamashi mai inganci akan iyakataccen yanki. IEC ce ta gabatar da wannan hanyar. Muna iya tsammanin kasashe da yawa za su yi la'akari da wannan hanyar. Duk da haka yana haɓaka babban buƙatu akan na'urorin laser. Yana buƙatar tushen Laser da ya dace da na'urori masu kariya daga radiation. A halin yanzu babu isassun lokuta don gwajin gudu na thermal, wannan hanyar har yanzu ana buƙatar tabbatarwa.
