Kubva ndichipinda mumusika,lithium mabhatiriakashandiswa zvakanyanya kune zvakanakira kwavo senge hupenyu hurefu, yakakura chaiyo kugona, uye hapana ndangariro maitiro. Kana yakashandiswa pakudziya kwakadzika, mabhatiri e-lithium-ion ane matambudziko akadai sekuderera kwesimba, kuderedzwa kwakanyanya, kutadza kutenderera kwekuita, kujeka kwe lithium precipitation, uye kusaenzana kwe lithium kuiswa uye kubviswa. Zvisinei, sezvo nzvimbo yekushandiswa inoramba ichiwedzera, zvipingamupinyi zvinounzwa nekushaya kutsika kwekushisa kwemabhatiri e-lithium-ion zviri kuramba zvichionekwa. Ngationgororei zvikonzero uye titsanangure nzira yekubata nayo lithium mabhatiri zvakanaka munguva yechando?
Hurukuro pamusoro pezvinhu zvinokanganisa kuderera kwekushisa kwe lithium mabhatiri
1. Electrolyte pesvedzero
Iyo electrolyte ine simba guru pane yakaderera-tembiricha kuita kwelithium mabhatiri. Kuumbwa uye physicochemical properties ye electrolyte ine kukosha kwakakosha pakuderera-kupisa kwebhatiri. Dambudziko rakatarisana nebhatiri kutenderera pakudzika kwakadzika nderekuti viscosity ye electrolyte ichawedzera, iyo ion conduction kumhanya inononoka, zvichikonzera kusawirirana mumagetsi ekufambisa kwemagetsi ekunze redunhu, saka bhatiri richave rakanyanya polarized uye kuchaja uye kubuda simba kunodonha zvakanyanya. Kunyanya kana ichichaja pane tembiricha yakaderera, lithium ions inogona nyore kugadzira lithium dendrites pamusoro peiyo negative electrode, zvichikonzera kutadza kwebhatiri.
2. Kufurirwa kwezvinhu zvisina kunaka zve electrode
- Battery polarization yakakomba panguva yakaderera-yepamusoro-yepamusoro-yekuchaja uye kuburitsa, uye yakawanda yakawanda yesimbi lithium inoiswa pamusoro peiyo yakaipa electrode. Kuita chigadzirwa chesimbi lithium uye electrolyte kazhinji haisi conductive;
- Kubva pane thermodynamic point of view, electrolyte ine nhamba yakawanda yemapoka epolar akadai se CO ne CN, iyo inogona kuita neine negative electrode material, uye SEI firimu yakaumbwa inonyanya kutarisana nekushisa kwakadzika;
- Zvakaoma kuti kabhoni negative electrodes isimbise lithium pane yakaderera tembiricha, uye pane asymmetry mukuchaja nekuburitsa.
Nzira yekubata sei lithium mabhatiri zvakanaka munguva yechando?
1. Usashandise mabhatiri e-lithium munzvimbo dzakaderera dzekushisa
Tembiricha ine simba guru pane lithium mabhatiri. Iyo yakadzika tembiricha, inodzikisira basa re lithium mabhatiri, izvo zvinotungamira zvakananga kudzikisira kwakakosha mukuchaja uye kuburitsa kushanda zvakanaka. Kazhinji kutaura, kupisa kwekushanda kwelithium mabhatiriiri pakati -20 madhigirii kusvika 60 madhigirii.
Kana tembiricha iri pasi pe 0 ℃, ngwarira kuti usachajire kunze. Tinogona kutora bhatiri mukati meimba yekuchaja (chinyorwa, ita shuwa kuti ugare kure nezvinhu zvinopisa !!!). Kana tembiricha iri pazasi -20 ℃, bhatiri rinobva rapinda munzvimbo yakarara uye haigone kushandiswa zvakajairika.
Naizvozvo, inonyanya kuvashandisi munzvimbo dzinotonhora kuchamhembe, kana pasina chaimo chekuchaja kwemukati, shandisa zvizere kupisa kwasara kana bhatiri raburitswa, uye uchachaja muzuva nekukurumidza mushure mekupaka kuti uwedzere huwandu hwekuchaja uye kudzivirira kunaya kwe lithium.
2. Ita tsika yekuchaja paunenge uchiishandisa
Munguva yechando, kana simba rebhatiri rakanyanya kuderera, tinofanira kurichaja nenguva uye kukudziridza tsika yakanaka yekuchaja paunenge uchiishandisa. Rangarira, usambofungidzira simba rebhatiri munguva yechando zvinoenderana nehupenyu hwebhatiri hwakajairika.
Muchando, basa relithium mabhatiriinodzikira, izvo zvinokonzeresa kuwandisa-kuburitsa uye kuwandisa-kuchaja, izvo zvinogona kukanganisa hupenyu hwebhatiri kana kutokonzera tsaona dzekutsva. Naizvozvo, munguva yechando, iwe unofanirwa kubhadhara zvakanyanya kubhadharisa mudiki discharge uye diki yekuchaja nzira. Kunyanya, usamisa mota kwenguva yakareba uchichaja kuti udzivise kuwandisa.
3. Usagare kure paunenge uchichaja. Rangarira kusachaja kwenguva yakareba.
Usachaja mota kwenguva yakareba nekuda kwekureruka. Ingoibvisa kana yazara. Nzvimbo yekuchaja munguva yechando haifanirwe kunge yakaderera kupfuura 0 ℃. Paunenge uchichaja, usabva kure zvakanyanya kudzivirira njodzi uye kugadzirisa nazvo nenguva.
4. Shandisa chaja yakatsaurirwa mabhatiri e lithium paunenge uchichaja.
Musika wacho uzere nemachaja emhando yakaderera. Kushandisa machaja emhando yakaderera kunokonzeresa kukuvara kwebhatiri uye kutokonzera moto. Usatenge zvigadzirwa zvemutengo wakaderera uye zvisina kuchengetedzwa nekuchipa, ndoda kushandisa lead-asidhi bhatiri charger; kana charger yako isinga shandiswe zvakajairika, rega kuishandisa nekukasira, uye usarasikirwa nemufananidzo mukuru weidiki.
5. Teerera kuhupenyu hwebheteri uye uitsive nenguva
Lithium mabhatiriuve nehupenyu. Mamiriro akasiyana uye mamodheru ane hupenyu hwakasiyana. Mukuwedzera, nekuda kwekushandiswa kusina kunaka kwezuva nezuva, hupenyu hwebheteri hunotangira kubva kumwedzi mishoma kusvika kumakore matatu. Kana mota ikapera simba kana hupenyu hwebhatiri hupfupi zvisingaite, ndapota taura nevashandi ve lithium bhatiri munguva yekuibata.
6. Siya rimwe simba rechando
Kuti ushandise motokari kazhinji muchirimo chegore rinouya, kana bhatiri risina kushandiswa kwenguva yakareba, yeuka kuichaja kusvika ku50% -80%, ibvise kubva mumotokari kuti uchengetedze, uye uibhadharise nguva dzose, inenge kamwe chete pamwedzi. Cherechedza: Bhatiri rinofanira kuchengetwa munzvimbo yakaoma.
7. Isa bhatiri nemazvo
Usanyudze bhatiri mumvura kana kuita kuti inyorove; usaisa bhatiri kupfuura 7 layers, kana kushandura nzira yebhatiri.
Mhedziso
Pa -20 ℃, simba rekuburitsa re lithium-ion bhatiri rinongoita 31.5% yeiyo pamhepo tembiricha. Tembiricha yekushanda yemabhatiri e-lithium-ion echinyakare ari pakati -20 uye +55 ℃. Nekudaro, muminda yeaerospace, indasitiri yemauto, mota dzemagetsi, nezvimwe, mabhatiri anodiwa kuti ashande zvakajairika pa -40 ℃. Naizvozvo, kuvandudza kuderera-kupisa zvimiro zvelithium-ion mabhatiri ane kukosha kukuru. Chokwadi, thelithium bhatiriindasitiri inogara ichikura, uye masayendisiti anoenderera mberi nekudzidza lithium mabhatiri anogona kushandiswa pakadzika tembiricha kugadzirisa matambudziko kune vatengi.
Heltec Energy ishamwari yako yaunovimba nayo mukugadzira bhatiri pack. Nekutarisa kwedu kusingagumi pakutsvaga nekusimudzira, pamwe nehupamhi hwemabhatiri ezvishandiso zvedu, tinopa mhinduro imwe chete yekusangana nezvinodiwa neindasitiri. Tinogona kugadzirisa mabhatiri e lithium kune akasiyana siyana evatengi. Kana iwe uchida kusimudzira yako lithium bhatiri kana kugadzirisa bhodhi rekudzivirira, ndapota taura nesu.
Kana uine chero mibvunzo kana uchida kudzidza zvakawanda, ndapota usazezasvika kwatiri.
