Kooxda cilmi-baarista sayniska ee Jaamacadda Les waxay ku salaysan yihiin cajalad, oo lagu daray qaar ka mid ah tignoolajiyada sare ee laysarka, waxayna soo saareen nooc cusub oo ah walxo koronto ah. Qalabkani wuxuu ka adkaan karaa dhibaatooyinka muddada-dheer ee baytariga lithium-ion ee hadda jira waxayna filayaan inay kordhiyaan waxqabadka batteriga. Baytariga birta ah ee Lithium waxaa loola jeedaa batari sida caadiga ah loo isticmaalo garaaf ahaan oo loo isticmaalo anode ahaan (laba electrodes) ilaa baytari bir saafi ah.

Maadaama maadadani leedahay cufnaanta tamar aad u saraysa, lithium bir ah waxay ka dhigi kartaa xawaaraha ku dallaca batteriga si weyn loo dardargeliyo, awooduna waxay gaari kartaa 10 jeer. Si kastaba ha ahaatee, waxaa weli jira qaar ka mid ah cilladaha baytariyada lithium-ion, taas oo aad u dhib badan "dendrites". Inta lagu jiro habka dallacaadda, dendrites-yadan ayaa lagu sameeyay dusha sare ee anode waxayna keeni kartaa wareegga gaaban, fashilka ama dabka, sidaas darteed tiro badan oo daraasado batteriga ah ayaa xoogga saaray.

Kooxda cilmi-baarista sayniska ee Jaamacadda Les ayaa horumar cusub ka sameeyay goobtan, marka hore waa cajalad. Kooxdu waxay cajaladda u gudbisaa ururiyaha hadda jira ee naxaasta ah ee ka kooban lithium anode waxayna ku daweeyeen layssar si ay ugu kululeeyaan heerkul aad u sarreeya oo ah 2300 Kelvin (3680 ¡ã F ama 2026 ¡ã C), si ay u siiso qayb cusub oo faa&39;iido leh. Habkani wuxuu cajaladda u rogaa dahaadh dalool leh, taas oo muhiim u ah silikoon, ogsijiin, iyo qadar yar oo ah graphene walxo sixir ah.

Tijaabooyin horudhac ah oo ku saabsan filimka ayaa muujinaya in loo isticmaali karo sida lakabka ilaalinta ee shirarka ururiyaha hadda jira, kaas oo nuugi kara oo sii deyn kara lithium bir ah, oo aan oggolaan doonin dendrites waxyeello leh. Dahaarka ilaalinta silikoon oksaydhka laysarka ee ay keentay, kooxda Jaamacadda Yar ayaa laga yaabaa inay heleen hab ay uga faa&39;iidaystaan ​​arrimahan togan, ee maaha culayska lithium ee dhowaan kordhay. Tijaabooyinkeedu waxay muujinayaan in batteriga dahaarka cusub uu soo bandhigayo saddex jeer nolosha baytariyada kale ee "eber-ka-dhaafka ah" ee baytariyada lithium-ion, wuxuuna kaydiyaa 70% awoodda 60 wareegyo.

Kooxdu waxay soo bandhigtay in tignoolajiyadan ay dhakhso badan tahay oo badbaado leh, aanay ku lug lahayn dareere, waxaana lagu samayn karaa heerkulka qolka. Sidaa darteed, aad ayaa loo rajeynayaa, waxay u maleyneysaa inay leedahay awood ay ku ballaariso miisaanka.
