I. Ihe sistemu ihe eji arụ ọrụ pụtara na nkọwapụta mpaghara elu (m2 / g): na-ezo aka n&39;akụkụ elu nke akụkụ ihe dị iche iche. (Ule ule: ịgbakọ argon olu adsorbed site na ihe nke unit arọ).

Oke urughuru (μm): Nkọwa nke irighiri ihe, na-ezo aka na dayameta nke ihe. D50 na-akọwa nkezi urughuru dayameta nke ihe. Njupụta efu (G / CM3): Ihe a na-ama jijiji n&39;oke oke nke unit nke nrụgharị igwe.

Tụkwasị na nke ahụ, e nwekwara ihe onwunwe n&39;onwe ya, ụdị ọdịdị ọdịdị, ikike ịwepu, ikike ịrụ ọrụ, ọdịnaya adịghị ọcha, na ihe ndị yiri ya bụkwa ihe mgbochi arụmọrụ nke ihe dị iche iche. Nke abụọ, dị iche iche ihe na electrode na isi ojiji e ji mara 1, conductive gị n&39;ụlọnga carbon ink conductive elekọta mmadụ, erughị ala carbon, ezi conductive Njirimara, ike adsorption, nnukwu kpọmkwem n&39;elu ebe, banyere 60-100 m2 / g, Ya onwe ya enweghị ikike. Onye na-eduzi graphite artificial, conductivity bụ obere ogbenye karịa ink carbon, mana mpaghara elu dị ntakịrị, 10-30 mAh / g, nke bụ ikike, ihe dịka 290 mAh / g, nke ka mma.

Enwekwara graphite eke, dabere na conductivity nke ya, enwere ike iji ya dị ka onye na-eduzi ihe, kamakwa dị ka ihe na-adịghị mma electrode n&39;ihi ikike dị elu. Na nano-ọnụ ọgụgụ carbon eriri, ezi conductivity, ezi nhazi arụmọrụ, ma price bụ oké ọnụ. 2, ihe electrode na-abụkarị batrị lithium ion nke abụọ, yana lithium cobaltate, ikike gram nke ya 135-150 mAh / g, njupụta kọmpat bụ 3.

65-4.00 g / cc, LiCoO2 bụ a lithium ion batrị nwere a nti electrode nwere oghere sekit voltaji elu. Elu karịa ike (usoro iwu karịa ike 1068Wh / kg, ikike ikike 274mAh / g), ogologo ndụ okirikiri, mwepu ngwa ngwa, mana ọnụahịa dị oke ọnụ.

Ihe elektrọd na-adịghị mma: graphite artificial, etiti oge carbon microsphere, mgbanwe graphite eke, wdg. Grafite wuruwuru nkịtị: ike gram 290-310mAh / g, kọmpat 1.45-1.

55g / cc. Microspheres nke etiti oge carbon: ikike gram 310-320mAh / g, compaction 1.55-1.

65g / cc. Mgbanwe graphite eke: ikike gram 320-340mAh / g, kọmpat 1.55-1.

65g / cc. 3, gluu bụ nke a ma ama maka PVDF, aha kemịkalụ bụ polyvinylidene fluoride, na nha nke viscosity ya na-emetụta ịdị arọ molekụla, ọnọdụ otu ọrụ na usoro nhazi. N&39;ozuzu, banyere otu usoro nhazi ahụ, otu ọnọdụ ọrụ na-arụ ọrụ, na-ebuwanye ibu nke molecular, otú ahụ ka viscosity ya dị elu, ma na-abawanye na viscosity, nkwụsị ya nke slurry na-apụtawanye ìhè.

CMC na SBR bụ gluu na-eji na usoro mmiri. CMC (carboxymethylcellulose): ọcha ma ọ bụ micro-edo edo ntụ ntụ, onwe ya nwere bonding Njirimara, ma na aqueous usoro, ya kasị isi ojiji ma ọ bụ dispersion ihe onwunwe na SBR. SBR (mmiri mmiri butadous-blene-blewell): eriri ọcha na-acha anụnụ anụnụ emulsion mmiri mmiri, ngwakọta polymer, agwakọta ya na CMC, yana ọrụ njikọta ya ka mma.

Nke atọ, batrị na-arụ ọrụ dị mma iji zute ọtụtụ ọnọdụ maka ihe, iji mee ka ọ dị mma, ọ bụghị iji ruo ọnọdụ ndị a: 1, ihe ahụ n&39;onwe ya Ọdịdị, nha nke urughuru size, granules Smoothness nke ọdịdị; mwepu otu nke ụmụ irighiri ihe na-arụ ọrụ na electrode; 3, molekul na-arụ ọrụ na onye na-eduzi ihe na-ahụ maka kọntaktị dị mma; 4, na-eduzi netwọkụ ahụ nke ọma; 5, na electrolyte mma infiltration ogo; 6, maka onye ọ bụla Ezi usoro ọnọdụ maka ihe onwunwe. Nke anọ, usoro mkpali na usoro 1, kpalie gluu PVDF: Dị ka ntinye uche ga-ahazi, a na-ezo aka ọnụ ọgụgụ PVDF akọrọ ntụ ntụ, tinye n&39;ime oven akọrọ, akpọọ nkụ 60-120 min na 70-80 degrees, wee na-ezo aka dị ka NMP N&39;ime ihe nrapado, a na-edozi akpa ahụ, na PVDF akọrọ ntụ ntụ na-agbanye ruo mgbe a na-etinye ntụ ntụ na PVDF. agbakwunyere, a na-emechi akpa ahụ dị ka o kwere mee, na-akpali 3-4h, ruo mgbe agbazere ya kpamkpam, jiri nwayọọ nwayọọ kpalie Seal ruo oge ụfọdụ iji wepụ ihe ndị dị na roba ma ọ bụ wụsa ngwọta ha n&39;ime akpa edozi. Nke a rọba dị mma, itinye uche ya bụ n&39;ozuzu 12%.

CMC: Usoro usoro bụ otu ihe ahụ, ma usoro ngwọta bụ mmiri dabeere na mmiri, ihe mgbaze bụ mmiri deionized karịa NMP, na ntinye nke ngwọta bụ n&39;ozuzu 2-3.5%. 2, Calcouting ihe na-a ihe onwunwe na agụụ oven maka 4 h na 160 ogo agụụ oven, na mgbe ahụ kpalite, na mgbe ahụ, kpalite, izugbe nzọụkwụ bụ ndị a: 2.

4 Na-agbakwunye SBR zuru oke na ọkwa elu, a na-agbaze kpamkpam na SBR, ihe dịka 30 min. (Achọrọ obere okpomọkụ na ngwa ngwa ngwa mgbe ị na-agbakwunye SBR) 3.5 Tinye ọdịnaya mmiri slurry 10-15% NMP (nwere NMP gbakwunyere na nzọụkwụ 1), jiri nwayọọ nwayọọ kpalie afụ ahụ, nkeji 30.

3.6 Wepu slurry, iyo. V.

Nsogbu nkịtị na nnwale ahụ, dozie nsogbu ahụ ma na-emetụta 1, nzube, oge na okpomọkụ nke ime achịcha. Ihe Electrode: iji wepu mmiri, mmanụ na uzuzu, ọnọdụ ime achịcha n&39;ozuzu 160 degrees 4h. Glue: Deflash dị mkpa, ọnọdụ ime achịcha n&39;ozuzu ogo 70-80 akpọọ nkụ 60-120min.

Oxic acid: na mgbakwunye na mmiri na mmiri kristal, ọnọdụ ime achịcha n&39;ozuzu 70-80 degrees maka 30-60 min. 2, ụkpụrụ nke ojiji nke conductive agents. A na-agwakọta ndị nduzi n&39;ozuzu, na-eji usoro mmịpụta.

3. Mmetụta onye na-eduzi ihe agbakwunyere na batrị. Ndị na-eduzi nwere obere emetụta ikike, okirikiri, ikpo okwu, elu na ala okpomọkụ Njirimara na elu ugbu a mwepu, nchekwa arụmọrụ, esịtidem iguzogide, wdg.

4, ihe dị iche n&39;usoro nke mgbakwunye nke ihe na uru na ọghọm. Onye na-eduzi na nrapado tinye usoro, oxalic acid tinye usoro, NMP tinye usoro n&39;ime ihe mmiri mmiri, wdg. 5, gluu gbakwunyere obere mmetụta na arụmọrụ batrị.

6. Gịnị bụ mmetụta nke ngwa ngwa jụrụ n&39;oge ihe. 7.

Otu esi aga n&39;ihu na mgbakwunye na ọnụọgụ oxalic acid na nhazi mmanu mmanu na oxalic acid. E nwere ihe abụọ nzube nke gaseous kpo oku: wepụ elu oxide oyi akwa nke ọla kọpa foil na-etolite a corrosive uzo n&39;elu nke ọla kọpa foil, na ifesa nke slurry na ọla kọpa foil. Ojiji ya na-abụkarị 2% nke PVDF.

8, CMC, SBR ojiji na akpachapụ anya na mmiri mmiri. Ma CMC na SBR nwere nrapado, eji na slurry, ebe CMC dị mkpa n&39;oge a, na SBR dị mkpa na bonding. 9.

Otu esi etinye NMP ma jiri mgbe nkesa mmiri adịghị mma. Ịgbakwunye NMP na electrode na-adịghị mma dị mkpa iji mee ka esemokwu dị elu nke foil na-adịghị mma, na-eme ka okpokoro slurry dịkwuo mma, na igbochi eriri nke pulp. Otú ọ dị, mgbe ị na-eri nri, ekwesịrị iburu n&39;uche na SBR na NMP bụ organic organics dị elu, ngwa ngwa ma ọ bụ okpomọkụ dị elu nwere ike imeghachi na ihe abụọ, na jelii na-ejikọta ya na gas.

10, mmekọrịta dị n&39;etiti ụdị siri ike, viscosity na gel. 11. Kedu ka oven dị ọkụ mgbe a na-adọta.

The pulp dị oke ala iji wetuo ntụ ntụ dị ala, ọnọdụ okpomọkụ dị oke elu, ntụ ntụ polar bụ ntụ ntụ, ma ọ bụ mgbawa dị ịrịba ama, ma enwere njem. 12, njupụta nke puls ewepụtara bụ nke na-ezighi ezi ma ọ bụ buru ibu. The slurry elu njupụta na-adịghị uniformly kewara n&39;ime ọtụtụ akụkụ: n&39;ihu na n&39;azụ njupụta nke polar mpempe akwụkwọ bụ ekwekọghị, abụọ n&39;akụkụ elu njupụta bụ ekwekọghị, na polar Ịgwakọta bụ unevenly mere diamonding oge na-ekwekọghị ekwekọ, ihe n&39;onwe ya bụ ejighị n&39;aka, na mulch njupụta njupụta bụ ejighị n&39;aka- Na e nwekwara a nnukwu njupụta ma ọ bụ a nnukwu njupụta.

13, na-emezigharị nrụgide rola. N&39;ụzọ abụọ, otu sitere na microstructure nke ihe ndị ahụ, nke abụọ sitere na ọdịdị nke electrode (gum, ntụ ọka, wrinkles). 14, n&39;oge mmepụta usoro na mgbe mmepụta ihe nkiri mgbe mmepụta.

Ebumnuche nke bred pole bụ iji wepụ mmiri mmiri, ma a na-achịkwa okpomọkụ na oge, na okpomọkụ na-ekpo ọkụ na-ekpo ọkụ bụ 130 degrees n&39;oge mmepụta, na okpomọkụ nke ihe nkiri ahụ bụ 90 degrees. 15, ọnọdụ nchekwa nke okporo osisi. Mgbe emechara ihe nkiri ahụ, a na-echekwa okporo osisi ahụ na ebe a na-emechi emechi.
