Ibhethri ye-graphene + lithium ≠ ibhethri legraphene

Abantu abalokhu bekhuluma ngamabhethri e-graphene empeleni abalungile.

Njenge-carbon nanomaterial, indima ye-graphene kumabhethri e-lithium aweqeli ububanzi bezinto zekhabhoni ezisetshenziswa kakhulu njengamanje.

Ibhethri ye-graphene + lithium ≠ ibhethri legraphene

Njengoba sazi, amabhethri e-lithium akhiwe ngezinto ezine ezinkulu: i-electrode ekhayo, i-electrode engemihle, i-diaphragm, ne-electrolyte. Into eyinhloko ye-electrode engalungile esetshenziswayo okwamanje i-graphite. I-graphene iyikristalu enezinhlangothi ezimbili enogqinsi olulodwa lwe-athomu (ama-nanometer angu-0.35) ehlutshiwe ku-graphite futhi yakhiwe ama-athomu ekhabhoni. Isebenza kangcono kune-graphite, futhi inokuguquguquka okuqine kakhulu, amandla aphakeme kakhulu, ukuqina okuphezulu, kanye ne-thermal conductivity ephezulu. Kuyaziwa ngokuthi "inkosi yezinto ezintsha." Abantu banethemba lokuthi izothatha indawo ye-graphite njenge-electrode engalungile yebhethri, noma isetshenziswe kwezinye izinto ezibalulekile zamabhethri e-lithium, ukuze kwandiswe kakhulu ukuminyana kwamandla kanye nokuqina kwamandla amabhethri e-lithium.

Njengamanje, abantu abaningi babiza amabhethri aqukethe izinto ze-graphene "amabhethri e-graphene." "Eqinisweni, ukubiza lawa mabhethri ngamabhethri e-graphene akuyona isayensi kakhulu futhi kuqinile, futhi lo mqondo awuhambisani nemigomo yokuqamba imboni futhi awukona ukuvumelana kwemboni." U-Yang Quanhong, isazi soMfula iYangtze soMnyango wezeMfundo, owawina iSikhwama Sikazwelonke Sezesayensi Yentsha Esivelele, kanye noprofesa eSikoleni Sobunjiniyela Bamakhemikhali eNyuvesi yaseTianjin, uveze engxoxweni abenayo neScience and Technology Daily ukuthi i-graphene ikhombisile. amandla amakhulu okusebenza kumabhethri e-lithium ngenxa yezakhiwo zayo eziyingqayizivele zomzimba namakhemikhali.Nokho, njenge-carbon nanomaterial, i-graphene ayidluli ububanzi bezinto zekhabhoni ezisetshenziswa njengamanje kumabhethri e-lithium. Nakuba kunemibiko eminingi emaphepheni esayensi nemikhiqizo yezinkampani mayelana ne-graphene ethuthukisa ukusebenza kwamabhethri e-lithium, indlela yayo yokugcina amandla eyinhloko ayizange ishintshe ngenxa yokwengezwa kwe-graphene, ngakho-ke akufaneleki ukubiza amabhethri e-lithium anezelwe amabhethri e-graphene graphene.
