1.Ibibazo byanduye nyuma yo gutunganya lithium fer fosifate
Isoko ry’ingufu zikoreshwa mu kongera ingufu ni nini, kandi nk’uko bitangazwa n’ibigo by’ubushakashatsi bireba, ingufu z’amashanyarazi z’izabukuru mu Bushinwa ziteganijwe kuzagera kuri 137.4MWh mu 2025.
Gufata litiro ya fer ya fosifatenk'urugero, hari uburyo bubiri bwo gutunganya no gukoresha bateri zikoresha amashanyarazi asezeye: imwe ni ikoreshwa rya casade, indi irasenya kandi ikongera.
Gukoresha Cascade bivuga ikoreshwa rya batiri yumuriro wa lithium fer fosifate ifite ubushobozi busigaye hagati ya 30% kugeza 80% nyuma yo kuyisenya no kuyisubiramo, no kuyishyira mubice bitarangwamo ingufu nke nko kubika ingufu.
Gusenya no gutunganya, nkuko izina ribigaragaza, bivuga gusenya bateri yumuriro wa lithium fer fosifate mugihe ubushobozi busigaye buri munsi ya 30%, hamwe no kugarura ibikoresho byabo bibisi, nka lithium, fosifore, nicyuma muri electrode nziza.
Gusenya no gutunganya bateri ya lithium-ion birashobora kugabanya ubucukuzi bwibikoresho bishya bibungabunga ibidukikije kandi bikagira n’agaciro gakomeye mu bukungu, bikagabanya cyane amafaranga y’ubucukuzi bw’amabuye y'agaciro, amafaranga yo gukora, amafaranga y’umurimo, n’ibiciro by’umurongo.
Ibyibandwaho muri batiri ya lithium-ion gusenya no gutunganya cyane cyane bigizwe nintambwe zikurikira: ubanza, gukusanya no gutondekanya bateri ya lithium yimyanda, hanyuma ugasenya bateri, hanyuma ukarangiza ukanatunganya ibyuma.Nyuma yo gukora, ibyuma byagaruwe hamwe nibikoresho birashobora gukoreshwa mugukora bateri nshya cyangwa ibindi bicuruzwa, bizigama cyane.
Ariko, ubu harimo itsinda ryamasosiyete atunganya ibicuruzwa bya batiri, nka Ningde Times Holding Co., Ltd ishami rya Guangdong Bangpu Circular Technology Co., Ltd., bose bahura nikibazo gikomeye: gutunganya bateri bizatanga uburozi bwibicuruzwa kandi bisohora imyanda yangiza. .Isoko rikeneye byihutirwa tekinolojiya mishya yo kunoza umwanda nuburozi bwa batiri.
2.LBNL yabonye ibikoresho bishya byo gukemura ibibazo by’umwanda nyuma yo gutunganya bateri.
Vuba aha, Lawrence Berkeley Laboratoire y'igihugu (LBNL) muri Amerika yatangaje ko babonye ibikoresho bishya bishobora gutunganya imyanda ya litiro-ion n'amazi gusa.
Laboratoire y'igihugu ya Lawrence Berkeley yashinzwe mu 1931 kandi icungwa na kaminuza ya Californiya ku biro bishinzwe ubumenyi muri Minisiteri ishinzwe ingufu muri Amerika.Yatsindiye ibihembo 16 bya Nobel.
Ibikoresho bishya byavumbuwe na Laboratoire yigihugu ya Lawrence Berkeley yitwa Byihuta-Kurekura Binder.Batteri ya Litiyumu-ion ikozwe muri ibi bikoresho irashobora gukoreshwa mu buryo bworoshye, itangiza ibidukikije, kandi idafite uburozi.Bakeneye gusa gusenywa no gushyirwa mumazi ya alkaline, no kunyeganyezwa buhoro kugirango batandukane ibintu bikenewe.Hanyuma, ibyuma byungururwa mumazi bikuma.
Ugereranije na lithium-ion ikoreshwa muri iki gihe, ikubiyemo gutemagura no gusya bateri, hagakurikiraho gutwikwa no gutandukanya ibyuma nibintu, bifite uburozi bukomeye n’imikorere mibi y’ibidukikije.Ibikoresho bishya ni nk'ijoro n'umunsi ugereranije.
Mu mpera za Nzeri 2022, iryo koranabuhanga ryatoranijwe nka bumwe mu buhanga 100 bw’impinduramatwara bwateye imbere ku isi mu 2022 na R&D 100 Awards.
Nkuko tubizi, bateri ya lithium-ion igizwe na electrode nziza kandi mbi, itandukanya, electrolyte, nibikoresho byubaka, ariko uburyo ibyo bice bihujwe muri bateri ya lithium-ion ntabwo bizwi neza.
Muri bateri ya lithium-ion, ibikoresho bikomeye bikomeza imiterere ya batiri ni ibifatika.
Binder nshya yihuta-yasohotse yavumbuwe nabashakashatsi ba Laboratoire yigihugu ya Lawrence Berkeley ikozwe muri acide polyacrylic (PAA) na polyethylene imine (PEI), ihujwe nubusabane hagati ya atome ya azote yuzuye neza muri PEI hamwe na atome ya ogisijeni yuzuye muri PAA.
Iyo Binder-Release Binder ishyizwe mumazi ya alkaline irimo hydroxide ya sodium (Na + OH-), ion ya sodium yinjira muburyo butunguranye, itandukanya polymers ebyiri.Polimeri yatandukanijwe ishonga mumazi, irekura ibice byose bya electrode.
Kubijyanye nigiciro, iyo bikoreshwa mugukora bateri ya lithium nziza kandi mbi ya electrode, igiciro cyibi bifata ni kimwe cya cumi cyibiri bikunze gukoreshwa
