The polima lithiamu batire amapangidwa pamaziko a madzi lithiamu ion batire.Elekitirodi ake zabwino ndi zoipa elekitirodi zipangizo ndi ofanana ndi madzi lithiamu ion batire, koma amagwiritsa gel osakaniza electrolyte ndi zotayidwa filimu pulasitiki monga ma CD akunja, choncho ali ndi kulemera mbandakucha.Zocheperako, kachulukidwe kamphamvu kwambiri komanso mawonekedwe achitetezo amakondedwa kwambiri ndi makasitomala apakhomo ndi akunja.
Nthawi zambiri, mabatire a lithiamu a polima amatanthauza mabatire a lithiamu okhala ndi filimu ya aluminiyamu yokutira kunja.Mabatire achitsulo-chipolopolo kapena square aluminium-shell lithiamu mabatire monga 18650 lithiamu mabatire saphatikizidwa.Kuyambira kupangidwa kwake mpaka pano, mabatire a lithiamu a polima aphatikiza mitundu itatu ya mabatire a lithiamu otsika kutentha, mabatire a lithiamu apamwamba kwambiri komanso mabatire apakati-kutentha kwambiri kwa lithiamu.
Kodi batire ya lithiamu ya polima imakhala yayitali bwanji?
Mabatire a lithiamu-ion amagawidwa m'mitundu iwiri: mabatire a lithiamu-ion polymer ndi mabatire amadzimadzi a lithiamu-ion.The zabwino ndi zoipa zipangizo polima lifiyamu-ion batire ndi madzi lithiamu-ion batire ndi chimodzimodzi, ndi mfundo ntchito batire ndi ofanana, koma electrolytes ndi osiyana wina ndi mzake.Battery ya lithiamu ya polima ndi yopepuka, imakhala ndi mphamvu zosungira mphamvu, ntchito yabwino yotuluka ndipo imatha kupangidwa mosiyanasiyana ndipo imakhala ndi moyo wautali.
Pansi pa muyezo wogwirizana wapadziko lonse, moyo wa batri suyimiridwa ndi nthawi, koma ndi kuchuluka kwa zozungulira, ndiko kuti, zimawerengedwa kamodzi mutatha kutulutsa kwathunthu.Batire ya lithiamu wamba imakhala pakati pa 500 ndi 800, ndipo batire ya polima ya A-grade ingagwiritsidwe ntchito.mpaka 800 nthawi.Chifukwa chake, mtundu wa batri wa wopereka batire wosankhidwa udzatsimikizika, ndipo moyo wautumiki udzakhala wautali.
Moyo wa batri wa polima uli ndi ubale wabwino ndi magwiridwe ake.Mabatire a lithiamu a polima amatchedwanso mabatire a polima.Malinga ndi maonekedwe, mabatire a polima amaikidwa mu zipolopolo za aluminiyamu-pulasitiki, zomwe zimakhala zosiyana ndi zipolopolo zazitsulo zamadzimadzi a lithiamu.Chifukwa chomwe chotengera cha aluminium-pulasitiki chingagwiritsidwe ntchito ndikuti batire ya polima imagwiritsa ntchito zinthu zina za colloidal kuthandiza mbale ya batire kuti ikwane kapena kuyamwa ma electrolyte, potero kuchepetsa kwambiri kuchuluka kwa electrolyte yamadzimadzi yomwe imagwiritsidwa ntchito.
Kuwongolera kwamapangidwe kumapangitsa kuti batire la polima likhale ndi zabwino zochulukirapo kachulukidwe mphamvu, kucheperako pang'ono komanso kuwonda kwambiri.Poyerekeza ndi mabatire amadzimadzi a lithiamu, mabatire a polima amakhala ndi moyo wautali, pafupifupi ma 500.Kuphatikiza apo, ngati batire ya lithiamu ya polima siilipidwa kwa nthawi yayitali, nthawi yamoyo idzachepanso.Mabatire a lithiamu polymer ayenera kusunga ma elekitironi awo kuyenda kwa nthawi yayitali kuti afikire moyo wawo wabwino.
Moyo wa batri ya lithiamu polima ndi wosiyana m'malingaliro ndi kagwiritsidwe ntchito, koma mawonekedwe ake amatsimikizira kuti moyo wa batri ya polima uli ndi zabwino zambiri kuposa mabatire azikhalidwe.Malinga ndi zomwe zimakhudza moyo wa batri la polima pochita, limatha kuyimbidwa kuchokera kukuya mpaka kukuya., magetsi oyenera, kutentha kosungirako koyenera kuti awonjezere moyo wa mabatire a lithiamu polymer.
Pakali pano, mtengo wamsika wa mabatire a lithiamu-ion polymer ndi wapamwamba kuposa mabatire a lithiamu-ion.Poyerekeza ndi mabatire a lithiamu-ion amadzimadzi, moyo wake ndi wautali komanso chitetezo chake ndi chabwino.Amakhulupirira kuti padzakhala malo ambiri oti asinthe posachedwapa.
Ubwino wa batri ya lithiamu polymer
Batire ya lithiamu-ion ya polima si yotetezeka kokha, komanso imakhala ndi ubwino wa kupatulira, malo osasunthika komanso mawonekedwe osasunthika, ndipo chipolopolocho chimagwiritsanso ntchito filimu yopepuka ya aluminiyamu-pulasitiki.Komabe, ntchito yake yotulutsa kutentha kwapang'onopang'ono ingakhalebe ndi mwayi wowongolera.
Ili ndi ntchito yabwino yotetezera.Batire ya lifiyamu ya polima imatenga ma aluminium-pulasitiki osinthika, omwe ndi osiyana ndi chipolopolo chachitsulo cha batri yamadzimadzi.Chiwopsezo chachitetezo chikachitika, batire yamadzimadzi imakhala yosavuta kuphulika, pomwe batire ya polima imangophulika kwambiri.
Kunenepa kwake ndi kochepa ndipo kumatha kukhala kocheperako.Wamba madzi lifiyamu batire utenga njira mwamakonda casing choyamba, ndiyeno plugging zabwino ndi zoipa elekitirodi zipangizo.Pali luso botolo pamene makulidwe ndi zosakwana 3.6mm, koma polima batire alibe vutoli, ndipo makulidwe akhoza kusintha.Pansi pa 1mm, zomwe zikugwirizana ndi kufunikira kwamakono kwa mafoni a m'manja.
Kulemera kwake, batire ya lithiamu ya polima ndi 40% yopepuka kuposa batire yachitsulo ya lithiamu yomwe ili ndi mphamvu yofananira, ndi 20% yopepuka kuposa batire ya aluminium chipolopolo.
Kuchuluka kwakukulu, batire ya polima imakhala ndi mphamvu ya 10-15% kuposa ya batire yachitsulo-chipolopolo chofanana ndi kukula kwake, ndi 5-10% kuposa batire ya aluminiyamu-chipolopolo, ndikupangitsa kuti ikhale chisankho choyamba pa foni yamakono. mafoni ndi mafoni a MMS.Mabatire a polima amagwiritsidwanso ntchito kwambiri.
The kukana mkati ndi yaing'ono, ndi kukana mkati mwa batire polima ndi ang'onoang'ono kuposa ambiri madzi batire.Pakalipano, kukana kwamkati kwa batire ya polima m'nyumba kumatha kukhala pansi pa 35mΩ, zomwe zimachepetsa kwambiri kudzigwiritsa ntchito kwa batire ndikutalikitsa nthawi yoyimilira ya foni yam'manja., akhoza kufika mokwanira pa mlingo wa miyezo ya mayiko.Batire iyi ya polima lifiyamu yomwe imathandizira kutulutsa kwakukulu kwapano ndi chisankho choyenera kwamitundu yowongolera kutali, ndipo yakhala chinthu chodalirika kwambiri chosinthira mabatire a nickel-metal hydride.
Mawonekedwe amatha kusinthidwa, batire ya lifiyamu ya polima imatha kukulitsa kapena kuchepetsa makulidwe a batire malinga ndi zosowa za makasitomala, kupanga ma cell atsopano a batri, mtengo wake ndi wotsika mtengo, kuzungulira kwa nkhungu ndikochepa, ndipo ena amatha kukhala opangidwa molingana ndi mawonekedwe a foni yam'manja kuti agwiritse ntchito mokwanira batire ya Shell danga, onjezerani mphamvu ya batri.
Monga mtundu wa batire lifiyamu, polima makamaka ubwino wa mkulu kachulukidwe, miniaturization, kopitilira muyeso-woonda ndi kulemera kuwala poyerekeza ndi madzi lifiyamu batire.Nthawi yomweyo, batire ya polymer lithiamu ilinso ndi zabwino zoonekeratu pachitetezo komanso kugwiritsa ntchito mtengo.Ubwino ndi batire yamphamvu yatsopano yomwe imadziwika ndi makampani.
