Mabatire a lithiamu ion omwe amatha kuchangidwa amagwiritsidwa ntchito kupatsa mphamvu zamagetsi zambiri pamoyo wathu watsiku ndi tsiku, kuyambira pa laputopu ndi mafoni am'manja mpaka pamagalimoto amagetsi.Mabatire a lithiamu ion pamsika masiku ano nthawi zambiri amadalira njira yamadzimadzi, yotchedwa electrolyte, pakatikati pa selo.

Pamene batire ikugwiritsa ntchito chipangizo, ma ion a lithiamu amasuntha kuchokera kumapeto komwe kuli koyipa, kapena anode, kudzera mu electrolyte yamadzimadzi, kupita kumapeto kwabwino, kapena cathode.Pamene batire ikuwonjezeredwa, ma ion amayenda mbali ina kuchokera ku cathode, kudzera mu electrolyte, kupita ku anode.

Mabatire a lithiamu ion omwe amadalira ma electrolyte amadzimadzi amakhala ndi vuto lalikulu lachitetezo: amatha kuyaka moto akamangidwa mochulukira kapena kufupikitsidwa.Njira yabwino yopangira ma electrolyte amadzimadzi ndikumanga batire yomwe imagwiritsa ntchito electrolyte yolimba kunyamula ayoni a lithiamu pakati pa anode ndi cathode.

Komabe, kafukufuku wam'mbuyomu adapeza kuti ma electrolyte olimba amatsogolera kukukula kwazitsulo zazing'ono, zotchedwa dendrites, zomwe zimamanga pa anode pomwe batri ikulipira.Ma dendrites awa amafupikitsa mabatire pamafunde otsika, kuwapangitsa kuti asagwiritsidwe ntchito.

Kukula kwa dendrite kumayambira pa zolakwika zazing'ono mu electrolyte pamalire a electrolyte ndi anode.Asayansi ku India posachedwapa apeza njira yochepetsera kukula kwa dendrite.Powonjezera chitsulo chochepa kwambiri pakati pa electrolyte ndi anode, amatha kuletsa ma dendrites kuti asakule kukhala anode.

Asayansiwo anasankha kuphunzira aluminiyamu ndi tungsten ngati zitsulo zomwe zingatheke kuti apange zitsulo zopyapyalazi.Izi zili choncho chifukwa palibe aluminium kapena tungsten mix, kapena alloy, yokhala ndi lithiamu.Asayansi amakhulupirira kuti izi zimachepetsa mwayi wa zolakwika zomwe zingapangidwe mu lithiamu.Ngati chitsulo chosankhidwa chikachita aloyi ndi lithiamu, lithiamu yaing'ono imatha kulowa muzitsulo zachitsulo pakapita nthawi.Izi zitha kusiya mtundu wa cholakwika chotchedwa void mu lithiamu pomwe dendrite imatha kupanga.

Pofuna kuyesa mphamvu ya zitsulo zosanjikiza, mitundu itatu ya mabatire inasonkhanitsidwa: imodzi yokhala ndi aluminium yopyapyala pakati pa lithiamu anode ndi electrolyte yolimba, imodzi yokhala ndi tungsten yopyapyala, ndi imodzi yopanda zitsulo.

Asanayese mabatire, asayansi adagwiritsa ntchito maikulosikopu yamphamvu kwambiri, yotchedwa scanning electron microscope, kuti awone bwino malire apakati pa anode ndi electrolyte.Iwo adawona mipata yaying'ono ndi mabowo pachitsanzo chopanda chitsulo chosanjikiza, ndikuzindikira kuti zolakwika izi ndizoyenera kuti ma dendrites akule.Mabatire onse awiri okhala ndi aluminiyamu ndi zigawo za tungsten ankawoneka bwino komanso mosalekeza.

Pakuyesa koyamba, mphamvu yamagetsi yokhazikika idayendetsedwa pa batire iliyonse kwa maola 24.Batire yopanda chitsulo chosanjikiza chozungulira ndikulephera mkati mwa maola 9 oyambirira, mwina chifukwa cha kukula kwa dendrite.Palibe batire yokhala ndi aluminiyamu kapena tungsten yomwe idalephera pakuyesa koyambiriraku.

Pofuna kudziwa kuti ndi chitsulo chiti chomwe chinali bwino poletsa kukula kwa dendrite, kuyesa kwina kunachitika pa zitsanzo za aluminiyamu ndi tungsten.Pakuyesa uku, mabatire adazunguliridwa kudzera pakuchulukirachulukira kwapano, kuyambira pakalipano omwe adagwiritsidwa ntchito poyesera kale ndikuwonjezeka pang'ono pa sitepe iliyonse.

Kachulukidwe kameneka komwe batire lalifupi limazungulira limakhulupirira kuti ndilofunika kwambiri pakukula kwa dendrite.Batire yokhala ndi aluminium wosanjikiza idalephera katatu poyambira, ndipo batire yokhala ndi tungsten idalephera kupitilira kasanu poyambira.Kuyesera uku kukuwonetsa kuti tungsten imaposa aluminiyamu.

Apanso, asayansi adagwiritsa ntchito makina owonera ma electron kuti awone malire pakati pa anode ndi electrolyte.Iwo adawona kuti voids idayamba kupangika muzitsulo zachitsulo pawiri pazitatu za zovuta zomwe zidayesedwa pakuyesa koyambirira.Komabe, voids sizinalipo pa gawo limodzi mwa magawo atatu a kachulukidwe kameneka.Izi zimatsimikizira kuti kupanga zopanda pake kumapitilira kukula kwa dendrite.

Asayansiwo adathamanga mawerengedwe owerengera kuti amvetsetse momwe lithiamu imagwirira ntchito ndi zitsulo izi, pogwiritsa ntchito zomwe tikudziwa za momwe tungsten ndi aluminiyamu zimayankhira mphamvu ndi kusintha kwa kutentha.Adawonetsa kuti zigawo za aluminiyamu zimakhaladi ndi mwayi wokulirapo wa voids mukalumikizana ndi lithiamu.Kugwiritsa ntchito mawerengedwewa kungapangitse kuti zikhale zosavuta kusankha mtundu wina wazitsulo kuti muyese mtsogolo.

Kafukufukuyu wasonyeza kuti mabatire olimba a electrolyte ndi odalirika kwambiri pamene zitsulo zopyapyala zawonjezeredwa pakati pa electrolyte ndi anode.Asayansi adawonetsanso kuti kusankha chitsulo chimodzi kuposa china, pamenepa tungsten m'malo mwa aluminiyamu, kumapangitsa kuti mabatire azikhala nthawi yayitali.Kuwongolera magwiridwe antchito amtundu wa mabatire awa kudzawabweretsera sitepe imodzi pafupi ndikusintha mabatire a electrolyte amadzimadzi omwe amayaka kwambiri pamsika lero.
