Basa reHollow Silicon Structures muLithium-Ion Mabhatiri
Silicon yave ichitaurwa nezvayo kwemakore semutambo-kuchinja zvinhu zve lithium-ion bhatiri anodes. Pabepa, inogona kuchengeta simba rakawanda kudarika rekare regirafu. Muchokwadi, zvakadaro, silicon inouya neyakakomba drawback: haina kuchembera zvakanaka. Mushure mekudzokororwa kubhadharisa uye kuburitsa mabhatiri, mazhinji mabhatiri esilicon anorasikirwa nekukasira nekukurumidza kupfuura zvaitarisirwa. Apa ndipo hollow silicon zvimiro vari kutanga kuita mutsauko chaiwo.
Why Cycle Life Inokosha Zvakawanda
Cycle life inoreva kuti kangani bhatiri rinogona kuchajwa nekuburitswa kushanda kwaro kusati kwadonha zvinooneka. Kumotokari dzemagetsi, masisitimu ekuchengetedza simba, uye kunyange zvemagetsi zvevatengi, hupenyu hupfupi hunoreva kudhura kwakanyanya, kuraswa kwakawanda, uye ruzivo rwevashandisi husina kunaka.
Yechinyakare yakasimba silicon masisitimu anowanzo kuwedzera zvakanyanya kana atora lithium. Nokufamba kwenguva, kuwedzera uku kunokonzera kuputika, kubviswa kwemagetsi, uye kusagadzikana kwebhatiri kushanda. Kunyangwe silicon ichipa huwandu hwepamusoro, kushaya simba kwayo kwechimiro kune kushoma-hombe yekugamuchirwa.
Sei Hollow Silicon Inochinja Mutambo
Hollow silicon zvimiro-kunyanya nano-scale hollow spheres-gadzirisa dambudziko iri padanho rekuumbwa. Panzvimbo pekusimba kwese, zvimedu izvi zvine goko rekunze rakatetepa uye nzvimbo isina chinhu mukati.
Iyo nzvimbo isina chinhu yakakosha. Kana lithium ichipinda musilicon panguva yekuchaja, zvinhu zvinowedzera mukati pamwe nekunze. Iyo hollow core inoita senge buffer, ichibvumira iyo particle kubata kushushikana pasina kutsemuka. Izvi zvinoderedza zvakanyanya kukuvadzwa kwemuchina pane inodzokororwa kutenderera.
Zvirinani Kugadzikana, Hurefu Hupenyu
Nokuti hollow silicon particles kashoma kutsemuka, vanochengeta zviri nani kusangana nezvinhu zvinoitisa mukati mebhatiri. Izvi zvinotungamirira kune dzimwe nzira dzakagadzikana dzemagetsi uye kuderera kwekuita zvishoma nezvishoma.
Mune mazwi anoshanda, mabhatiri anoshandisa hollow silicon zvimiro anowanzo ratidza:
· Kuderera kwesimba kunononoka
· Kuvandudzwa kwechimiro chekuvimbika nekufamba kwenguva
· Kuwedzera kuenderana kuita pabvunzo refu dzebhasikoro
Nepo iwo chaiwo mhedzisiro zvichienderana nekugadzira uye kugadzirisa, maitiro akajeka: chimiro chiri nani chinotungamira kune hupenyu huri nani hwekutenderera.
Nzvimbo Yepamusoro uye Kuita Kubudirira
Imwe mukana we hollow silicon zvimiro ndiyo nzvimbo yavo yepamusoro inoshanda yepamusoro. Izvi zvinobvumira lithium ions kuti ifambe ichipinda nekubuda zvakaenzana, ichideredza kushushikana kwenzvimbo uye kupisa kuvaka. Kuwedzera kuita kwakafanana kunoreva mashoma asina kusimba, izvo zvinowedzera kuwedzera hupenyu hwebhatiri.
Panguva imwecheteyo, mashefu esilicon akaonda anopfupisa nzira dzekuparadzira, zvichibatsira kuvandudza kuchaja uye kuburitsa kunyatsoshanda pasina kupa kusimba.
Kuenzanisa Kuita uye Mutengo
Hollow silicon zvinhu zvakanyanya kuomarara kugadzira kupfuura zvimedu zvakasimba, izvo zvinogona kukwidza mutengo. Nekudaro, hupenyu hurefu hwekutenderera hunoreva kutsiva kushoma uye kukosha kwenguva refu-kunyanya kune yakakwirira-yekupedzisira maapplication senge mota dzemagetsi uye grid kuchengetedza.
Sezvo matekiniki ekugadzira achiramba achivandudza, masimbi esilicon zvimiro zviri kuwedzera kuita zvekushandisa mukutengesa.
Kutsigira Advanced Battery Materials neHuazhong Gasi
Panguva Huazhong gasi, tinoshanda padhuze nevagadziri vezvinhu zvebhatiri uye vagadziri nekupa yakakwirira-kuchena yakakosha magasi akakosha pakugadziriswa kwesilicon, kukoira, uye nanomaterial kugadzirwa. Yedu yakagadzikana yekugovera cheni, yakasimba mhando zviyero, uye inopindura tekinoroji rutsigiro inobatsira vatengi kusundira kuvandudza bhatiri mberi-pasina kukanganisa kuvimbika.
Kana kutsvagisa kwako kwebhatiri kana kugadzirwa kuchitsamira pane zvepamberi silicon zvinhu, Huazhong Gasi riripo kutsigira kutenderera kwese kumberi.
