Iyo nharaunda iyo iyo polymer lithium bhatiri inoshandiswa yakakoshawo zvakanyanya mukupesvedzera hupenyu hwayo hwekutenderera.Pakati pavo, ambient tembiricha chinhu chakakosha zvikuru.Tembiricha yakadzikira kana yakawandisa inogona kukanganisa hupenyu hwemabhatiri eLi-polymer.Mumagetsi mabhatiri maapplication uye maapplication uko tembiricha iri pesvedzero huru, yekupisa manejimendi yeLi-polymer mabhatiri inodiwa kuvandudza kushanda kwebhatiri.

Zvikonzero zvemukati tembiricha shanduko yeLi-polymer bhatiri paki

ForLi-polymer mabhatiri, iyo yemukati kupisa chizvarwa ndeye reaction heat, polarization kupisa uye Joule kupisa.Chimwe chezvikonzero chikuru chekuwedzera kwekushisa kweLi-polymer bhatiri kuwedzera kwekushisa kunokonzerwa nekupikiswa kwemukati kwebhatiri.Pamusoro pezvo, nekuda kwekumisikidzwa kwakaomeswa kwesero rinopisa, nzvimbo yepakati inosungirwa kuunganidza kupisa kwakawanda, uye nharaunda yekumucheto ishoma, izvo zvinowedzera kusaenzana kwekushisa pakati pemaseru ega muLi-polymer bhatiri.

Polymer lithium bhatiri tembiricha yekudzora nzira

1. Kugadziriswa kwemukati

Iyo tembiricha sensor ichaiswa mune inomiririra zvakanyanya, iyo yakakura tembiricha shanduko munzvimbo, kunyanya yakanyanya uye yakaderera tembiricha, pamwe nepakati pepolymer lithium bhatiri kupisa kuunganidza nzvimbo ine simba.

1. Mutemo wekunze

Kutonhodza mutemo: Parizvino, tichifunga kuoma kweiyo thermal manejimendi chimiro cheLi-polymer mabhatiri, mazhinji acho anotora chimiro chakareruka chemhepo-kutonhora nzira.Uye tichifunga nezvekufanana kwekupisa kwekupisa, vazhinji vavo vanotora nzira inopindirana yemhepo.

1. Tembiricha kudzora: iyo yakapfava yekudziya chimiro ndeyekuwedzera kupisa mahwendefa pamusoro uye pasi peLi-polymer bhatiri kuita kupisa, kune tambo yekudziya pamberi uye mushure mega yega Li-polymer bhatiri kana kushandiswa kwekudziya firimu rakaputirwa mukati.Li-polymer bhatiriyekupisa.

Zvikonzero zvikuru zvekudzikiswa kwesimba re lithium polymer mabhatiri pakudziya kwakaderera

1. Kusaita zvakanaka kweelectrolyte conductivity, kunyorova uye / kana kupera kweiyo diaphragm, kunonoka kutama kwe lithium ions, kunonoka kubhadharisa mutengo pa electrode/electrolyte interface, nezvimwe.

2. Mukuwedzera, iyo impedance yeSEI membrane inowedzera pakudzika kwakadzika, inoderedza chiyero che lithium ions inopfuura ne electrode / electrolyte interface.Chimwe chezvikonzero zvekuwedzera kweimpedance yeSEI firimu ndeyekuti zviri nyore kuti lithium ions ibude kubva kune yakaipa electrode pakudziya kwakadzika uye zvakanyanya kuoma kupinza.

3. Paunenge uchichaja, lithium simbi ichaonekwa uye inopindirana ne electrolyte kuti iite itsva SEI firimu kuti ivhare yepakutanga SEI firimu, iyo inowedzera impedance yebhatiri zvichiita kuti simba rebhatiri riderere.

Kupisa kwakadzika pakuita kwe lithium polymer mabhatiri

1. yakaderera tembiricha pachaji uye discharge kuita

Sezvo tembiricha inoderera, avhareji yekuburitsa voltage uye yekuburitsa kugona kwelithium polymer mabhatirizvakadzikiswa, kunyanya kana tembiricha iri -20 ℃, bhatiri rekuburitsa simba uye avhareji yekuburitsa voltage inodzikira nekukurumidza.

2. Kupisa kwakadzika pamusoro pekuita kwekutenderera

Kugona kwebhatiri kuparara nekukurumidza pa -10 ℃, uye simba rinongoramba riri 59mAh / g mushure memazana zana, ne 47.8% kuora simba;bhatiri rinoburitswa pakushisa kwakadzika rinoedzwa pakamuri tembiricha yekuchaja uye kuburitsa, uye kugona kudzoreredza kuita kunoongororwa munguva.Kugona kwayo kwakadzoreredzwa ku70.8mAh/g, nekurasikirwa kwehuwandu hwe68%.Izvi zvinoratidza kuti kudzika-tembiricha kutenderera kwebhatiri kune zvakanyanya kukanganisa kudzoreredza kwebhatiri huwandu.

3. Kuderera kwekushisa kwepasi pakuita kwekuchengetedza

Polymer lithium battery charging inzira yelithium ion inobva papositive electrode kuburikidza neelectrolyte migration yakaiswa mu negative material, lithium ions kusvika kune negative electrode polymerization, nemaatomu matanhatu ecarbon anobata lithium ion.Pakutonhora kwakadzika, basa rekuita kemikemikari rinoderedzwa, nepo kutama kwe lithium ion kunowedzera kunonoka, iyo lithium ion pamusoro peiyo negative electrode haina kuiswa mukati meiyo negative electrode yakaderedzwa kuita lithium metal, uye kunaya kwemvura pa pamusoro peiyo negative electrode kuumba lithium dendrites, iyo inogona kubaya nyore diaphragm ichikonzera pfupi pfupi mubhatiri, iyo inogona kukuvadza bhatiri uye kukonzera njodzi dzekuchengetedza.

Chekupedzisira, isu tichiri kuda kukuyeuchidzai kuti lithium polymer mabhatiri anonyanya kusachajwa munguva yechando pane tembiricha yakaderera, nekuda kwekudziya kwakaderera, iyo lithium ion yakaiswa paiyo negative electrode inoburitsa makristasi eion, ichibaya diaphragm zvakananga, izvo zvinowanzokonzera micro-short circuit inokanganisa hupenyu nekuita, kuputika kwakakomba kwakananga.Saka vamwe vanhu vanoratidza yechando polymer lithium bhatiri yekuchaja haigone kubhadhariswa, izvi zvinokonzerwa nechikamu nebhatiri manejimendi system nekuda kwekuchengetedzwa kwechigadzirwa.
