Bateri bita polymer lithium yerekana bateri ya lithium ion ikoresha polymer nka electrolyte, kandi igabanijwemo ubwoko bubiri: "semi-polymer" na "all-polymer".“Semi-polymer” bivuga gutwikira urwego rwa polymer (ubusanzwe PVDF) kuri firime ya bariyeri kugirango ingirabuzimafatizo ikomeze, bateri irashobora gukomera, kandi electrolyte iracyari electrolyte y'amazi."Polimeri zose" bivuga gukoresha polymer kugirango ube umuyoboro wa gel imbere muri selire, hanyuma utere electrolyte kugirango ube electrolyte.Nubwo bateri "all-polymer" iracyakoresha electrolyte yamazi, umubare ni muto cyane, utezimbere cyane imikorere yumutekano wa bateri ya lithium-ion.Nkuko mbizi, gusa SONY arimo gukora byinshi "byose-polymer"bateri ya lithium-ion.Uhereye kubindi bice, bateri ya polymer bivuga ikoreshwa rya firime ya aluminium-plastike nkibipfunyika hanze ya bateri ya lithium-ion, bizwi kandi nka bateri yoroshye.Ubu bwoko bwo gupakira bugizwe nibice bitatu, aribyo PP layer, Al layer na nylon.Kuberako PP na nylon ari polymers, ubu bwoko bwa bateri bwitwa polymer bateri.

Itandukaniro riri hagati ya batiri ya lithium na bateri ya polymer

1. Ibikoresho fatizo biratandukanye.Ibikoresho fatizo bya batiri ya lithium ion ni electrolyte (amazi cyangwa gel);ibikoresho fatizo bya batiri ya polymer lithium ni electrolytike harimo polymer electrolyte (ikomeye cyangwa colloidal) na electrolyte organic.

2. Kubijyanye numutekano, bateri ya lithium-ion iraturika gusa mubushyuhe bwo hejuru kandi bwumuvuduko mwinshi;bateri ya polymer lithium ikoresha firime ya plastike ya aluminium nkigikonoshwa cyo hanze, kandi iyo amashanyarazi akoreshwa imbere, ntashobora guturika nubwo amazi yaba ashyushye.

3. Imiterere itandukanye, bateri ya polymer irashobora kuba yoroheje, ikozwe uko bishakiye, kandi uko bishakiye.Impamvu nuko electrolyte ishobora kuba ikomeye cyangwa colloidal aho kuba amazi.Batteri ya Litiyumu ikoresha electrolyte, isaba igikonoshwa gikomeye.Ipaki ya kabiri irimo electrolyte.

4. Umuvuduko wa bateri ya selile iratandukanye.Kuberako bateri ya polymer ikoresha ibikoresho bya polymer, birashobora gukorwa mubice byinshi kugirango bigere kuri voltage ndende, mugihe ubushobozi bwizina bwa selile ya litiro ni 3.6V.Niba ushaka kugera kuri voltage ndende mubikorwa, Voltage, ugomba guhuza selile nyinshi murukurikirane kugirango ukore urubuga rwiza rwumuriro.

5. Uburyo bwo kubyaza umusaruro buratandukanye.Batiyeri ya polymer yoroheje, nibyiza kubyara umusaruro, hamwe na batiri ya lithium, niko umusaruro uba mwiza.Ibi bituma porogaramu ya batiri ya lithium yagura imirima myinshi.

6. Ubushobozi.Ubushobozi bwa bateri ya polymer ntabwo bwatejwe imbere neza.Ugereranije nubushobozi busanzwe bwa batiri ya lithium, haracyari kugabanuka.

Ibyiza byabateri ya polymer

1. Imikorere myiza yumutekano.Bateri ya polymer lithium ikoresha aluminiyumu-plastike yoroheje ipakira muburyo, itandukanye nicyuma cya batiri yamazi.Iyo ikibazo kibangamiye umutekano kibaye, batiri ya lithium ion iraturika gusa, mugihe bateri ya polymer izaturika gusa, kandi byinshi bizatwikwa.

2. Umubyimba muto urashobora gukorwa muburyo bworoshye, ultra-thin, umubyimba urashobora kuba munsi ya 1mm, urashobora guteranyirizwa mumakarita yinguzanyo.Hano hari tekinike ya tekinike yubunini bwa bateri isanzwe ya litiro iri munsi ya 3.6mm, naho bateri ya 18650 ifite amajwi asanzwe.

3. Uburemere bworoshye nubushobozi bunini.Bateri ya polymer electrolyte ntabwo ikenera igikonoshwa nkicyuma gikingira hanze, iyo rero ubushobozi buringaniye, iba yoroshye 40% kuruta batiri ya lithium yicyuma na 20% byoroshye kuruta bateri ya aluminium.Iyo ingano ari nini muri rusange, ubushobozi bwa bateri ya polymer nini, hafi 30%.

4. Imiterere irashobora gutegurwa.Bateri ya polymer irashobora kongera cyangwa kugabanya ubunini bwa selile ya batiri ukurikije ibikenewe bifatika.Kurugero, ikaye nshya yikimenyetso kizwi ikoresha bateri ya trapezoidal polymer kugirango ikoreshe byuzuye umwanya wimbere.

Inenge ya bateri ya polymer lithium

(1) Impamvu nyamukuru nuko igiciro kiri hejuru, kuko gishobora gutegurwa ukurikije ibyo umukiriya akeneye, kandi ikiguzi cya R&D hano kigomba kubamo.Mubyongeyeho, imiterere nuburyo butandukanye byatumye habaho ibisobanuro nyabyo kandi bitari byo byifashishwa mu bikoresho bitandukanye, hamwe n’ibiciro byiyongera.

(2) Bateri ya polymer ubwayo ifite imikorere idahwitse, nayo izanwa no gutegura neza.Birakenewe kenshi gutegura imwe kubakiriya guhera kubitandukaniro rya 1mm.

(3) Niba ivunitse, izajugunywa burundu, kandi birasabwa kugenzura uruziga.Kurenza urugero cyangwa kurenza urugero byangiza ihinduka ryimiti yimbere ya bateri, bizagira ingaruka zikomeye kubuzima bwa bateri.
