Iyo inonzi inonzi polymer lithium battery inoreva lithium ion bhatiri inoshandisa polymer se electrolyte, uye yakakamurwa kuva marudzi maviri: "semi-polymer" uye "all-polymer".“Semi-polymer” inoreva kufukidza chidimbu chepolymer (kazhinji PVDF) pabhairi firimu kuita kuti kunamatira kwesero kusimbe, bhatiri rinogona kuomeswa, uye electrolyte ichiri mvura ye electrolyte.Iyo "polymer yose" inoreva kushandiswa kwepolymer kuumba gel network mukati mesero, uye ipapo jekiseni electrolyte kuti iite electrolyte.Kunyange zvazvo mabhatiri e "all-polymer" achiri kushandisa electrolyte yemvura, mari yacho iduku zvikuru, iyo inovandudza zvikuru kushanda kwekuchengetedza kwe lithium-ion mabhatiri.Sekuziva kwangu, SONY chete parizvino iri kugadzira "all-polymer"lithium-ion mabhatiri.Kubva pane chimwe chidimbu, bhatiri repolymer rinoreva kushandiswa kwealuminium-plastiki yekurongedza firimu seyekunze yekurongedza yelithium-ion mabhatiri, anozivikanwawo semabhatiri e-soft-pack.Iri rudzi rwekurongedza firimu rinoumbwa nezvikamu zvitatu, zvinoti PP layer, Al layer uye nylon layer.Nekuti PP nenaironi mapolymer, rudzi urwu rwebhatiri rwunodaidzwa kuti polymer bhatiri.

Musiyano uripo pakati pe lithium ion bhatiri uye polymer lithium bhatiri

1. The raw materials akasiyana.Iyo mbishi ye lithium ion mabhatiri ndeye electrolyte (mvura kana gel);iyo mbishi yepolymer lithium bhatiri maelectrolyte anosanganisira polymer electrolyte (yakasimba kana colloidal) uye organic electrolyte.

2. Panyaya yekuchengeteka, lithiamu-ion mabhatiri anongoputika munzvimbo yakakwirira-yekushisa uye yakakwirira-kudzvinyirira;polymer lithium mabhatiri anoshandisa aluminium epurasitiki firimu seganda rekunze, uye kana organic electrolytes ikashandiswa mukati, haizoputika kunyangwe mvura ichipisa.

3. Maumbirwo akasiyana, mabhatiri epolymer anogona kutetepa, akaumbwa zvisina tsarukano, uye akaumbwa zvisina tsarukano.Chikonzero ndechekuti electrolyte inogona kuva yakasimba kana colloidal kwete mvura.Lithium mabhatiri anoshandisa electrolyte, iyo inoda goko rakasimba.Iyo yechipiri packaging ine electrolyte.

4. Bhatiri cell voltage yakasiyana.Nekuda kwekuti mabhatiri epolymer anoshandisa zvinhu zvepolymer, anogona kugadzirwa kuita musanganiswa we-multi-layer kuti awane high voltage, ukuwo simba rezita relithium bhatiri masero ari 3.6V.Kana iwe uchida kuwana yakakwira voltage mukuita, Voltage, unofanirwa kubatanidza maseru akawanda munhevedzano kuti aumbe yakanakira yakakwirira-voltage yebasa chikuva.

5. Nzira yekugadzira yakasiyana.Iyo yakatetepa bhatiri repolymer, zvirinani kugadzirwa, uye kukora kwebhatiri re lithium, zviri nani kugadzirwa.Izvi zvinobvumira kushandiswa kwemabhatiri e-lithium kuwedzera mamwe minda.

6. Kugona.Kugona kwemabhatiri epolymer hakuna kunyatso kuvandudzwa.Kuenzaniswa neyakajairwa simba lithium mabhatiri, kuchine kudzikiswa.

Zvakanakira zvepolymer lithium bhatiri

1. Kuita kwakanaka kwekuchengetedza.Iyo polymer lithium bhatiri inoshandisa aluminium-plastiki yakapfava yekurongedza muchimiro, iyo yakasiyana nesimbi shell yemvura bhatiri.Kamwe njodzi yekuchengetedza ikaitika, bhatiri re lithium ion rinongoputika, nepo bhatiri repolymer rinongoputika, uye rinonyanya kupiswa.

2. Ukobvu hudiki hunogona kuitwa hutete, hutete-tete, ukobvu hunogona kunge husingasviki 1mm, hunogona kuunganidzwa mumakadhi echikwereti.Iko kune tekinoroji bhodhoro rehukobvu hweakajairwa mvura lithium bhatiri pazasi 3.6mm, uye bhatiri re18650 rine vhoriyamu yakajairwa.

3. Chiedza chechiedza uye simba guru.Iyo polymer electrolyte bhatiri haidi simbi seganda rekunze rekudzivirira, saka kana simba rakafanana, rinoreruka ne40% pane simbi shell lithium bhatiri uye 20% yakareruka pane aluminium shell bhatiri.Kana vhoriyamu ichiwanzokura, huwandu hwebhatiri repolymer hwakakura, hunosvika makumi matatu muzana.

4. Chimiro chinogona kugadziriswa.Iyo polymer bhatiri inogona kuwedzera kana kuderedza ukobvu hwebhatiri sero zvinoenderana nezvinodiwa zvinoshanda.Semuyenzaniso, kabhuku katsva kechinyorwa chakakurumbira chinoshandisa trapezoidal polymer bhatiri kushandisa zvizere nzvimbo yemukati.

Kukanganisa kwepolymer lithium bhatiri

(1) Chikonzero chikuru ndechekuti mutengo wakakwira, nekuti unogona kurongwa zvinoenderana nezvinodiwa nemutengi, uye mutengo weR&D pano unofanirwa kuverengerwa.Uye zvakare, iwo akasiyana maumbirwo uye marudzi akatungamira kune kwakaringana uye kwakashata kutaurwa kweakasiyana maturusi uye zvigadziriso mukuita kwekugadzira, uye zvakawedzera mutengo.

(2) Iyo bhatiri yepolymer pachayo ine hurombo hwakasiyana-siyana, hunounzwawo nekuronga kwakadzama.Zvinowanzodikanwa kuronga imwe yevatengi kubva pakutanga kune musiyano we1mm.

(3) Kana ikavhuniwa, icharaswa zvachose, uye kuchengetedzwa kwedunhu kunodiwa.Kuwedzeresa kana kuwandisa kunokuvadza kudzoreredzwa kwemukati wemakemikari zvinhu zvebhatiri, izvo zvinokanganisa zvakanyanya hupenyu hwebhatiri.

(4) Hupenyu hupfupi pane 18650 nekuda kwekushandiswa kwezvirongwa zvakasiyana uye zvinhu, mamwe ane mvura mukati, mamwe akaoma kana colloidal, uye kuita hakuna kunaka se18650 cylindrical mabhatiri kana aburitswa pakakwirira ikozvino.
