Ike njigide dị elu: CMC na-egosipụta ihe nrapado siri ike, na-enyere ya aka ijikọta ihe ndị na-arụ ọrụ nke ọma na elu onye nchịkọta ugbu a, si otú ahụ na-eme ka nkwụsi ike electrode dịkwuo mma.
Ikike imepụta ihe nkiri dị mma: CMC nwere ike mepụta otu ihe nkiri na nnukwu ihe nkiri na mbara elektrọd, na-eme ka ntinye nke ihe ndị na-arụ ọrụ na-eme ka mmekọrịta electrode-electrolyte dịkwuo mma.
Ndakọrịta gburugburu ebe obibi: Dị ka polymer na-adịghị egbu egbu na-esi na isi mmalite emeghari, CMC na-enye uru gburugburu ebe obibi karịa ihe ndị na-emepụta sịntetik dị ka PVDF.

(1) Nrụpụta Electrode:

A na-ejikarị CMC eme ihe dị ka ihe nchikota n'ichepụta electrodes maka kemịkalụ batrị dị iche iche, gụnyere batrị lithium-ion (LIBs), batrị sodium-ion (SIBs), na supercapacitors.
Na LIBs, CMC na-eme ka njikọ dị n'etiti ihe na-arụ ọrụ (dịka ọmụmaatụ, lithium cobalt oxide, graphite) na onye na-anakọta ugbu a (dịka ọmụmaatụ, foil ọla kọpa), na-eduga n'iguzosi ike n'ezi ihe electrode na mbelata delamination n'oge ịgba ígwè.
N'otu aka ahụ, na SIBs, electrodes dabeere na CMC na-egosipụta nkwụsi ike dị mma na ịrụ ọrụ ịgba ígwè ma e jiri ya tụnyere electrodes nwere ihe eji eme ihe.
The film-akpụ ike nkeCMCna-eme ka mkpuchi otu nke ihe na-arụ ọrụ na onye na-achịkọta ugbu a, na-ebelata porosity electrode ma na-emeziwanye ion transport kinetics.

Ọ bụ ezie na CMC n'onwe ya adịghị eduzi, ntinye ya n'ime usoro electrode nwere ike ime ka njikwa ọkụ eletrik zuru ezu nke electrode.
A na-eji usoro dị ka mgbakwunye nke ihe mgbakwunye na-eduzi (dịka ọmụmaatụ, carbon ojii, graphene) n'akụkụ CMC iji belata ihe mgbochi jikọtara na electrodes dabeere na CMC.
Sistemụ ihe nkwekọ ngwakọ na-ejikọta CMC na polymers conductive ma ọ bụ carbon nanomaterials egosila nsonaazụ na-ekwe nkwa na imeziwanye conductivity electrode na-achụghị ihe eji arụ ọrụ.

3.Electrode Stability na Ịgba Ịrụ Ọrụ:

CMC na-arụ ọrụ dị oke mkpa n'ịkwado nkwụsi ike electrode yana igbochi mwepu ihe ma ọ bụ agglomeration n'oge ịgba ígwè.
Mgbanwe na nrapagide siri ike nke CMC na-enye na-enye aka na nrụpụta ọrụ nke electrodes, karịsịa n'okpuru ọnọdụ nrụgide siri ike n'oge usoro ịgbasa ụgwọ.
