Chii chinonzi polymer bhatiri?

Iyo polymer lithium bhatiri inogadzirwa pahwaro hweiyo liquid lithium ion bhatiri.Yayo yakanaka electrode uye negative electrode zvinhu zvakafanana neiyo liquid lithium ion bhatiri, asi inoshandisa gel electrolyte uye aruminiyamu epurasitiki firimu sepakeji yekunze, saka ine huremu hwakareruka.Yakaonda, yakakwira simba density uye kuchengetedza maficha anofarirwa zvakanyanya nevatengi vekumba nevekunze.

Kazhinji kutaura, mabhatiri e-polymer lithium anoreva mabhatiri e-lithium ane akapfava-akaputirwa aruminiyamu firimu rekunze kurongedza.Simbi-shell mabhatiri kana square aluminium-shell lithium mabhatiri akadai se18650 lithium mabhatiri haana kubatanidzwa.Kubva pakugadzirwa kwayo kusvika ikozvino, mabhatiri e-polymer lithium akabatanidza marudzi matatu e-low-temperature lithium mabhatiri, high-rate lithium mabhatiri uye yepakati-yakakwirira tembiricha lithium mabhatiri.

Hupenyu hurefu hwepolymer lithium bhatiri?

Lithium-ion mabhatiri akakamurwa kuita marudzi maviri: polymer lithium-ion mabhatiri uye liquid lithium-ion mabhatiri.Izvo zvakanaka uye zvisina kunaka zvinhu zvepolymer lithium-ion bhatiri uye mvura lithium-ion bhatiri zvakafanana, uye nheyo yekushanda yebheteri yakafanana, asi electrolytes yakasiyana kubva kune mumwe.Iyo polymer lithium bhatiri haina huremu, ine simba rakasimba rekuchengetedza simba, yakanaka yekuburitsa kuita uye inogona kugadzirwa akasiyana maumbirwo uye ine hupenyu hwakareba.

Pasi pehutano hwepasi rose hwakabatana, hupenyu hwebheteri hahumiriri nenguva, asi nehuwandu hwekutenderera, kureva kuti, inoverengwa kamwe chete mushure mekusununguka kwakakwana.Iyo general lithium bhatiri iri pakati pe500 ne800 nguva, uye A-giredhi repolymer bhatiri rinogona kushandiswa.kusvika ku800 nguva.Naizvozvo, kunaka kwebhatiri yemupi webhatiri yakasarudzwa ichavimbiswa, uye hupenyu hwebasa huchave hwakareba.

Upenyu hwebhatiri repolymer hune hukama hukuru nekuita kwayo.Polymer lithium mabhatiri anonziwo mabhatiri epolymer.Kubva pamaonero echitarisiko, mabhatiri epolymer akaiswa mualuminium-epurasitiki mabhomba, ayo akasiyana nematehwe esimbi emvura lithium mabhatiri.Chikonzero nei iyo aluminium-plastiki kesi inogona kushandiswa ndeyekuti bhatiri repolymer rinoshandisa zvimwe zvinhu colloidal kubatsira bhatiri ndiro kukwana kana kutora electrolyte, nekudaro ichidzikisa zvakanyanya huwandu hwemvura ye electrolyte inoshandiswa.

Kuvandudzwa kwechimiro kunoita kuti bhatiri repolymer rive nemabhenefiti eiyo yakakwira simba density, yakawanda miniaturization uye yakanyanya-kuonda.Kuenzaniswa nemabhatiri e-lithium emvura, mabhatiri epolymer ane hupenyu hwakareba, angangoita mazana mashanu ma cycle.Uye zvakare, kana iyo polymer lithium bhatiri isina kubhadhariswa kwenguva yakareba, hupenyu huchadzikira zvakare.Lithium polymer mabhatiri anofanirwa kuchengetedza maerekitironi awo achiyerera kwenguva yakareba kuti asvike hupenyu hwawo hwakakodzera.

Hupenyu hwe lithium polymer bhatiri hwakasiyana mune dzidziso uye nekushandisa, asi maitiro ekumisikidza anoona kuti hupenyu hwepolymer bhatiri hune mabhenefiti makuru pane echinyakare mabhatiri.Zvinoenderana nezvinokonzeresa hupenyu hwepolymer bhatiri mukuita, inogona kuchajwa kubva pakadzika kusvika pakadzika., inonzwisisika voltage, yakakodzera yekuchengetedza tembiricha kuwedzera hupenyu hwepolymer lithium mabhatiri.

Parizvino, mutengo wemusika wepolymer lithium-ion mabhatiri wakakwira kupfuura iwo emvura lithium-ion mabhatiri.Kuenzaniswa nemabhatiri e-lithium-ion emvura, hupenyu hwayo hurefu uye kuchengetedzwa kwayo kwakanaka.Zvinotendwa kuti pachava nenzvimbo yakawanda yekuvandudza munguva pfupi iri kutevera.

Lithium polymer bhatiri zvakanakira

Iyo polymer lithium-ion bhatiri haina kuchengetedzeka chete, asi zvakare ine zvakanakira kutetepa, nzvimbo yekupokana uye chimiro chekupokana, uye goko rinoshandisawo yakareruka aluminium-plastiki composite firimu.Nekudaro, iyo yakaderera-tembiricha yekuburitsa kuita kwayo inogona kunge ichine nzvimbo yekuvandudza.

Iine hutano hwakanaka hwekuchengetedza.Iyo polymer lithium bhatiri inotora aluminium-plastiki inochinjika kurongedza muchimiro, iyo yakasiyana nesimbi ganda remvura bhatiri.Kana njodzi yekudzivirira yaitika, bhatiri remvura riri nyore kuputika, nepo bhatiri repolymer rinongoputika zvakanyanya.

Ukobvu hudiki uye hunogona kuitwa hutete.Iyo yakajairwa mvura yelithium bhatiri inotora nzira yekugadzirisa iyo casing kutanga, yobva yadzvanya izvo zvakanaka uye zvisina kunaka electrode zvinhu.Iko kune tekinoroji bhodhoro kana ukobvu huri pasi pe3.6mm, asi bhatiri repolymer harina dambudziko iri, uye ukobvu hunogona kugadziriswa.Pazasi pe1mm, inoenderana nezvinodiwa parizvino zvemafoni.

Huremu huremu, iyo polymer lithium bhatiri inoreruka makumi mana muzana pane simbi shell lithium bhatiri ine zvakafanana kugona kutsanangurwa, uye 20% yakareruka kupfuura aluminium shell bhatiri.

Huru hukuru, bhatiri repolymer rinokwanisa kuita 10-15% yakakwirira kudarika yesimbi-shell bhatiri rehukuru hwakafanana, uye 5-10% yakakwirira kupfuura bhatiri realuminium-shell, zvichiita kuti ive sarudzo yekutanga yeruvara rweruvara rwefoni. nharembozha uye MMS nharembozha.Mabhatiri epolymer anoshandiswawo zvakanyanya.

Iko kupikisa kwemukati kudiki, uye kupikisa kwemukati kwebhatiri repolymer idiki pane iro reiyo bhatiri remvura.Parizvino, kupikisa kwemukati kwebhatiri repolymer yemumba kunogona kunge kuri pasi pe35mΩ, izvo zvinoderedza zvakanyanya kuzvishandisa kwebhatiri uye kuwedzera nguva yekumira kwenharembozha., inogona kusvika zvizere pamwero wemitemo yenyika.Iyi polymer lithium bhatiri inotsigira hombe yekuburitsa ikozvino isarudzo yakanaka yemhando dzekudzora kure, uye yave chigadzirwa chinovimbisa kutsiva nickel-metal hydride mabhatiri.

Chimiro chinogona kugadzirwa, iyo polymer lithium bhatiri inogona kuwedzera kana kuderedza ukobvu hwebhatiri sero zvinoenderana nezvinodiwa nevatengi, gadzira mhando nyowani dzemabhatiri cell, mutengo wakachipa, mold yekuvhura kutenderera ipfupi, uye mamwe anogona yakagadzirirwa zvinoenderana nechimiro chenhare mbozha kushandisa zvizere bhatiri Shell nzvimbo, kuwedzera bhatiri huwandu.

Serudzi rwe lithium bhatiri, polymer inonyanya kuve nemabhenefiti ehupamhi hwepamusoro, miniaturization, yekupedzisira-mutete uye huremu huremu kana ichienzaniswa neyemvura lithium bhatiri.Panguva imwecheteyo, polymer lithium bhatiri zvakare ine mabhenefiti ari pachena mukuchengetedza uye mutengo wekushandisa.Zvakanakira bhatiri resimba idzva rinowanzo zivikanwa neindasitiri.
