Gukora ibikoresho byiza kandi bibi

Mugutegura ibikoresho bya elegitoroniki ya electrode ya bateri ya lithium ion, ubushyuhe bwo hejuru bukomeye leta reaction niyo ikoreshwa cyane.Ubushyuhe bwo hejuru cyane-reaction reaction: bivuga inzira reaction zirimo ibintu bya fase-fonction reaction mugihe runaka mubushyuhe runaka kandi bigatanga imiti yimiti ikwirakwizwa hagati yibintu bitandukanye kugirango itange ibice bihamye mubushyuhe runaka , harimo reaction ikomeye, reaction ya gaze na reaction-ikomeye.

Nubwo uburyo bwa sol-gel, uburyo bwa coprecipitation, uburyo bwa hydrothermal nuburyo bwa solvothermal bwakoreshejwe, reaction ya fonctionnement cyangwa fonctionnement ya fonctionnement yubushyuhe bwo hejuru.Ni ukubera ko ihame ryakazi rya batiri ya lithium-ion risaba ko ibikoresho bya electrode bishobora kwinjiza inshuro nyinshi no kuvanaho li +, bityo imiterere ya lattice yayo igomba kuba ifite ituze rihagije, bisaba ko kristu yibikoresho bigomba kuba hejuru kandi imiterere ya kristu igomba kuba isanzwe .Ibi biragoye kubigeraho mubihe byubushyuhe buke, kubwibyo ibikoresho bya electrode ya bateri ya lithium-ion ikoreshwa muri iki gihe iboneka ahanini binyuze mu bushyuhe bwo hejuru cyane-reaction.

Umurongo wo gutunganya ibikoresho bya cathode urimo cyane cyane kuvanga sisitemu, sisitemu yo gucumura, sisitemu yo kumenagura, sisitemu yo gukaraba amazi (nikel gusa), sisitemu yo gupakira, sisitemu yo gutanga ifu hamwe na sisitemu yo kugenzura ubwenge.

Iyo kuvanga amazi bitose bikoreshwa mugukora ibikoresho bya cathode ya bateri ya lithium-ion, ibibazo byo kumisha bikunze guhura nabyo.Umuti utandukanye ukoreshwa muburyo bwo kuvanga amazi bizaganisha kumyuma n'ibikoresho bitandukanye.Kugeza ubu, hari ubwoko bubiri bwumuti ukoreshwa muburyo bwo kuvanga amazi: ibishishwa bidafite amazi, aribyo bimera nka Ethanol, acetone, nibindi;Amashanyarazi.Ibikoresho byo kumisha kuvanga amazi ya batiri ya lithium-ion ya cathode yibikoresho ahanini birimo: vacuum rotary dryer, vacuum rake dryer, spray yumye, vacuum umukandara.

Inganda zikora inganda za cathode ya bateri ya lithium-ion mubisanzwe ikoresha ubushyuhe bwo hejuru-bukomeye bwa sintezime ya synthesis, kandi ibikoresho byibanze nibikoresho byingenzi ni gucana itanura.Ibikoresho fatizo byo gukora ibikoresho bya cathode ya lithium-ion bivangwa kimwe kandi byumye, hanyuma bishyirwa mu itanura kugirango bicumure, hanyuma bipakururwe mu itanura muburyo bwo kumenagura no gushyira mubikorwa.Kugirango habeho ibikoresho bya cathode, ibipimo bya tekiniki nubukungu nkubushyuhe bwo kugenzura ubushyuhe, uburinganire bwubushyuhe, kugenzura ikirere nuburinganire, gukomeza, ubushobozi bwo gukora, gukoresha ingufu hamwe n’ikigereranyo cy’itanura ni ngombwa cyane.Kugeza ubu, ibikoresho nyamukuru byo gucumura bikoreshwa mugukora ibikoresho bya cathode ni itanura rya pusher, itanura rya roller hamwe nitanura rya jar.

Itanura rya Roller ni itanura rinini rinini rifite itara rihoraho hamwe no gushyushya.

◼ Ukurikije ikirere cy'itanura, nk'itanura rya pusher, itanura rya roller naryo rigabanyijemo itanura ry'ikirere hamwe n'itanura ry'ikirere.

• Itanura ryo mu kirere: rikoreshwa cyane cyane mu gucumura bisaba umwuka wa okiside, nk'ibikoresho bya lithium manganate, ibikoresho bya okiside ya lithium cobalt, ibikoresho bya ternary, n'ibindi;
• Itanura rya Atmosifike: rikoreshwa cyane cyane mubikoresho bya NCA, ibikoresho bya lithium fer fosifate (LFP), ibikoresho bya grafite anode nibindi bikoresho byangiza bikenera ikirere (nka N2 cyangwa O2) kurinda gaze.

Itanura rya roller ryemera uburyo bwo guterana amagambo, bityo uburebure bw'itanura ntibuzagerwaho n'ingufu zo gusunika.Mubyukuri, birashobora kutagira iherezo.Ibiranga imiterere ya cavit yubatswe, guhuzagurika neza mugihe cyo kurasa ibicuruzwa, hamwe nubunini bunini bwamatara bifasha cyane kugendagenda kwumwuka mwuka mu itanura no kuvoma no gusohora ibicuruzwa.Nibikoresho byatoranijwe gusimbuza itanura rya pusher kugirango tumenye neza umusaruro munini.

Present Kugeza ubu, lisiyumu ya cobalt oxyde, ternary, lithium manganate hamwe nibindi bikoresho bya cathode ya bateri ya lithium-ion byacuzwe mu itanura ry’ikirere, mu gihe fosifate ya lithiyumu icungwa mu itanura ryakingiwe na azote, naho NCA ikayungurura muri roller itanura ririnzwe na ogisijeni.
