Incamake y'uburyo bwo gukurura electrode nziza n'imbi ya bateri ya lithium ion

Ubwa mbere, ihame ryo kuvanga
Mu gukangura ibyuma n'urukuta ruzunguruka kugira ngo bizunguruke, imiterere y'icyuma irakorwa kandi igakomeza gukoreshwa, kandi uburyo bwo kohereza ibintu hagati y'amazi n'ibice bikomeye burushaho kwiyongera. Gukangura ibintu bikomeye bikunze kugabanywamo ibice bikurikira: (1) guhagarika ibice bikomeye; (2) kongera guhagarika ibice by'ibice by'ibice; (3) kwinjira kw'ibice by'ibice by'ibice mu mazi; (4) gukoresha hagati y'ibice no hagati y'ibice n'ibice by'ibice Imbaraga zituma ibice by'ibice bikwirakwira cyangwa bigategeka ingano y'ibice; (5) uburyo bwo kohereza ibintu bikomeye hagati y'amazi n'ibice bikomeye.

Icya kabiri, ingaruka zo gukangura

Uburyo bwo guhuza ibintu buvanga ibice bitandukanye biri mu gikarabiro mu buryo busanzwe kugira ngo hategurwe igikarabiro kugira ngo byorohereze gusiga neza no kwemeza ko ibice by'inkingi bihora bihuye. Ibikoresho muri rusange bigizwe n'ibikorwa bitanu, aribyo: gutunganya mbere, kuvanga, gutose, gukwirakwiza no gukurura ibikoresho fatizo.

Icya gatatu, ibipimo by'ubushyuhe

1, ubushyuhe:

Ubudahangarwa bw'amazi ku gutemba busobanurwa nk'ingano y'umuvuduko wo gukata ukenewe kuri buri gipimo cya 25 px 2 iyo amazi atemba ku gipimo cya 25 px / s, cyitwa kinematic viscosity, muri Pa.s.
Ubushyuhe ni umwihariko w'amazi. Iyo amazi atemba mu muyoboro, habaho imiterere itatu y'amazi atemba, amazi atemba mu buryo bw'impinduka, n'amazi atemba mu buryo bw'ihindagurika. Iyi imiterere itatu y'amazi nayo iboneka mu bikoresho byo gukangura, kandi kimwe mu bipimo by'ingenzi bigena imiterere y'amazi ni ubushyuhe bw'amazi.
Mu gihe cyo gukangura, muri rusange bifatwa nk'aho ubushyuhe buri munsi ya 5 Pa.s ni amazi afite ubushyuhe buke, nka: amazi, amavuta ya castor, isukari, jam, ubuki, amavuta yo kwisiga, emulsion ifite ubushyuhe buke, nibindi; 5-50 Pas ni amazi afite ubushyuhe buke Urugero: wino, amenyo y'amenyo, nibindi; 50-500 Pas ni amazi afite ubushyuhe buke, nka chewing gum, plastisol, lisansi ikomeye, nibindi; Pas zirenga 500 ni amazi afite ubushyuhe buke cyane nka: uruvange rwa rubber, plastic melts, organic Silicon nibindi.

2, ingano y'uduce D50:

Ingano y'ingano y'uduce duto ni 50% ukurikije ingano y'uduce turi mu gishanga

3, ibikubiye mu nyandiko bifatika:

Ijanisha ry'ibintu bikomeye mu gishanga, igipimo cy'ibikubiye mu gishanga ni gito ugereranyije n'ibikubiye mu gishanga

Icya kane, igipimo cy'ingaruka zivanze

Uburyo bwo kumenya uburyo bwo kuvanga no kuvanga sisitemu yo gufunga ibintu bikomeye n'amazi bungana:

1, gupima mu buryo butaziguye

1) Uburyo bwo gupima ubushyuhe: gupima ubushyuhe bw'ubushyuhe ukoresheje viscometer; uko ubushyuhe bugabanuka, niko kuvanga bingana;

2) Uburyo bw'uduce duto:

A, gupima ibintu uhereye ahantu hatandukanye muri sisitemu, hakoreshejwe agakoresho gapima ingano y'uduce kugira ngo harebwe ingano y'uduce tw'urusenda; uko ingano y'uduce yegereye ingano y'ifu y'ibikoresho fatizo, ni ko kuvanga birushaho kuba bimwe;

B, gupima ibintu uhereye ahantu hatandukanye muri sisitemu, hakoreshejwe icyuma gipima ingano y'uduce tw'ururenda cya laser kugira ngo harebwe ingano y'uduce tw'ururenda; uko ingano y'uduce ikwirakwira neza, ni ko uduce duto turushaho kuba duto, ni ko uruvange rurushaho kuba rumwe;

3) Uburyo bwihariye bwo gukuramo imbaraga: gupima ibintu uhereye mu myanya itandukanye y'uburyo, gupima ubucucike bw'urusobe rw'amazi, uko ihindagurika rito, niko kuvanga bingana.

2. Gupima mu buryo butaziguye

1) Uburyo bw'ibipimo bikomeye (macroscopike): Gutoranya ibintu bitandukanye mu buryo, nyuma y'ubushyuhe bukwiye n'igihe gikwiye cyo guteka, gupima uburemere bw'igice gikomeye, uko ihinduka rito, niko kuvanga bingana;

2) SEM/EPMA (mikorosikope): icyitegererezo giturutse ahantu hatandukanye muri sisitemu, gishyire ku gice cy'ubutaka, wumishe, kandi urebe uduce cyangwa ibintu biri muri firime nyuma yo kumisha ururenda ukoresheje SEM (mikorosikope ya elegitoroniki) / EPMA (probe ya elegitoroniki) Ikwirakwizwa; (ibintu bikomeye bya sisitemu akenshi ni ibikoresho by'umuyoboro)

Gatanu, inzira yo gukurura anode

Umukara wa karuboni itwara amashanyarazi: Ikoreshwa nk'igikoresho gitwara amashanyarazi. Imikorere: Guhuza uduce duto tw'ibikoresho bikora kugira ngo amashanyarazi abe meza.

Latex ya Copolymer — SBR (styrene butadiene rubber): ikoreshwa nk'icyuma gifunga. Izina ry'imiti: Styrene-Butadiene copolymer latex (polystyrene butadiene latex), latex ishongera mu mazi, ifite ingano ikomeye 48 ~ 50%, PH 4 ~ 7, aho ubukonje bugera kuri -5 ~ 0 °C, aho ubushyuhe bushyuha hafi 100 °C, ubushyuhe bwo kubika 5 ~ 35 ° C. SBR ni polymer ikwirakwira mu buryo bwa anionic ifite ubushobozi bwo kudahinduka no gukora neza, kandi ifite imbaraga zo gufatanya cyane.

Selulosi ya sodium carboxymethyl (CMC) – (carboxymethyl cellulose sodium): ikoreshwa nk'ingufu zikomeza no gushimangira. Ishusho ni ifu y'umweru cyangwa umuhondo ya floc fibre cyangwa ifu yera, nta mpumuro, nta buryohe, ntabwo ari uburozi; ishongesha mu mazi akonje cyangwa mu mazi ashyushye, ikora jeli, umuti ni ntarengwa cyangwa ufite alkaline gato, ntushongesha muri ethanol, ether, Umushongi w'ibinyabuzima nka isopropyl alcohol cyangwa acetone ushongesha mu gisubizo cy'amazi cya 60% cya ethanol cyangwa acetone. Ni hygroscopic, ihamye ku mucyo n'ubushyuhe, viscosity iragabanuka uko ubushyuhe bwiyongera, umuti uba uhamye kuri pH 2 kugeza 10, PH iri munsi ya 2, ibintu bikomeye birahinduka, na pH iri hejuru ya 10. Ubushyuhe bw'ibara bwari 227 ° C, ubushyuhe bwa karubone bwari 252 ° C, kandi imbaraga z'ubuso bw'umushongi w'amazi wa 2% zari 71 nm/n.

Uburyo bwo gukurura no gusiga anode ni ubu bukurikira:

 
Icya gatandatu, inzira yo gukurura cathode

Umukara wa karuboni itwara amashanyarazi: Ikoreshwa nk'igikoresho gitwara amashanyarazi. Imikorere: Guhuza uduce duto tw'ibikoresho bikora kugira ngo amashanyarazi abe meza.

NMP (N-methylpyrrolidone): ikoreshwa nk'umusemburo uvangavanga. Izina ry'ikinyabutabire: N-Methyl-2-polyrrolidone, formula ya molekile: C5H9NO. N-methylpyrrolidone ni amazi ahumura gato ya ammonia avanganywa n'amazi mu buryo ubwo aribwo bwose kandi hafi ya yose avanze n'ibintu byose biyungurura (ethanol, acetaldehyde, ketone, aromatic hydrocarbon, nibindi). Aho ubushyuhe bushyuha ni 204 ° C, aho ubushyuhe bushyuha ni 95 ° C. NMP ni umusemburo wa polar aprotic ufite uburozi buke, aho ubushyuhe bushyuha cyane, aho ubushyuhe bushyuha neza, aho gushonga neza, aho guhitamo no kudahungabana. Ikoreshwa cyane mu gukuramo aromatike; gutunganya acetylene, olefins, diolefins. Umusemburo ukoreshwa muri polymer n'uburyo bwo gushonga ubu ukoreshwa muri sosiyete yacu kuri NMP-002-02, ufite ubuziranenge bwa >99.8%, uburemere bwihariye bwa 1.025 ~ 1.040, n'amazi angana na <0.005% (500ppm).

PVDF (polivinilidene fluoride): ikoreshwa nk'imashini ikomeza ubushyuhe n'ubukonje. Polymeri y'umweru ifite ifu ya crystalline ifite ubucucike buri hagati ya 1.75 na 1.78. Ifite ubudahangarwa bwiza cyane bwa UV no guhangana n'imihindagurikire y'ikirere, kandi firime yayo ntabwo ikomeye cyangwa ngo ivunike nyuma yo gushyirwa hanze mu gihe cy'imyaka igera kuri makumyabiri. Imiterere ya dielectric ya polyvinylidene fluoride ni yihariye, dielectric constant iri hejuru ya 6-8 (MHz ~ 60Hz), kandi dielectric loss tangent nayo ni nini, hafi 0.02 ~ 0.2, kandi ingano yayo ni ntoya gato, ari yo 2 × 1014ΩNaN. Ubushyuhe bwayo bukoreshwa igihe kirekire ni -40 ° C ~ +150 ° C, muri ubu bushyuhe, polymer ifite imiterere myiza ya mekanike. Ifite ubushyuhe bw'impinduka mu kirahure bwa -39 ° C, ubushyuhe bwa embrittlement bwa -62 ° C cyangwa munsi yayo, crystal ishonga ya 170 ° C, n'ubushyuhe bwa 316 ° C cyangwa irenga.

Uburyo bwo gukurura no gusiga cathode:

7. Ibiranga ubukana bw'urutare

1. Ingano y'ubushyuhe bw'ibinure hamwe n'igihe cyo kubivanga

Uko igihe cyo gukangura kigenda cyongerwa, ubushyuhe bw'urusenda bukunda kuba agaciro gahamye kadahinduka (bishobora kuvugwa ko urusenda rwatatanijwe neza).

2. Ingano y'ubushyuhe bw'urubura hamwe n'ubushyuhe

Uko ubushyuhe burushaho kuba bwinshi, ni ko ubushyuhe bw'ibinure bugabanuka, kandi ubushyuhe burushaho kuba bwiza iyo bugeze ku bushyuhe runaka.

3. Ingano y'ibikubiye mu gikoresho cyo kohereza amazi mu buryo bufatika uko igihe kigenda gihita

Nyuma y'uko urusenda rumaze gukangwa, rushyirwa mu cyuma cyo koherezamo ibintu kugira ngo rutwikirirwe na Coater. Ikigega cyo koherezamo ibintu kirakangwa kugira ngo kizunguruke: 25Hz (740RPM), revolution: 35Hz (35RPM) kugira ngo ibipimo by'urusenda bihamye kandi bitazahinduka, harimo n'ibinure. Ubushyuhe bw'ibikoresho, ubushyuhe n'ibipimo bikomeye kugira ngo habeho ingano y'urusenda.

4, ubukana bw'urutare hamwe n'igihe
