Nhanganyaya:
Mabhatiri anogona kukamurwa zvakafara muzvikamu zvitatu: mabhatiri emakemikari, mabhatiri emuviri uye mabhatiri ehupenyu. Makemikari mabhatiri ndiwo anonyanya kushandiswa mumotokari dzemagetsi.
Kemikari bhatiri: Kemikari bhatiri mudziyo unoshandura simba remakemikari kuita simba remagetsi kuburikidza nekuita kwemakemikari. Inosanganisira yakanaka uye yakaipa electrodes uye electrolytes.
Bhatiri remuviri: Bhatiri remuviri rinoshandura simba remuviri (senge simba rezuva uye simba remuchina) kuita simba remagetsi kuburikidza nekuchinja kwemuviri.
Kemikari bhatiri kupatsanurwa: Kubva pakuumbwa kwemaonero, inogona kukamurwa kuita mapoka maviri: ekuchengetedza mabhatiri (kusanganisira ekutanga mabhatiri uye echipiri mabhatiri) uye masero emafuta. Mabhatiri ekutanga: anogona kushandiswa kamwe chete, iyo inoshanda haidzokerike, iyo yekuzviburitsa idiki, iyo yemukati kuramba yakakura, uye huwandu hwakasiyana hukuru uye vhoriyamu yakananga huwandu hwakakwirira.
Sekondari mabhatiri: anogona kuchajwa uye kuburitswa kakawanda, iyo inoshanda inodzoreredzwa, uye inoshandiswa zvakanyanya mumidziyo yekuchaja yakasiyana. Mazhinji emamodheru pamusika parizvino anoshandisa yechipiri bhatiri rechargeable kutyaira mota. Sekondari mabhatiri akakamurwa kuita lead-asidhi mabhatiri, nickel-cadmium mabhatiri, nickel-metal hydride mabhatiri uye lithium mabhatiri maererano akasiyana-siyana akanaka electrode zvinhu. Parizvino, makambani emotokari mumusika anonyanya kushandisalithium mabhatiri, uye vashomanana vanoshandisa nickel-metal hydride mabhatiri.
Tsanangudzo ye lithium bhatiri
Lithium bhatiriibhatiri rinoshandisa lithium simbi kana lithium alloy seyakanaka kana yakaipa electrode zvinhu uye isiri-aqueous electrolyte mhinduro.
Iyo yekuchaja uye yekuburitsa maitiro e lithium bhatiri inonyanya kutsamira pakufamba kwe lithium ions (Li +) pakati peiyo yakanaka uye yakaipa electrode. Paunenge uchichaja, lithium ions inodzivirirwa kubva kune yakanaka electrode uye yakaiswa mukati meiyo yakaipa electrode kuburikidza ne electrolyte, uye iyo yakaipa electrode iri mune lithium-rich state; zvakapesana ndezvechokwadi pakubvisa.
Electrochemical musimboti we lithium-ion bhatiri
Positive electrode reaction formula: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Negative electrode reaction formula: C + xLi+ + xe- → CLix
Lithium-ion mabhatiri ane simba rakanyanya density, hupenyu hurefu uye yakaderera yekuzviburitsa, uye anoshandiswa zvakanyanya munharembozha, malaptop uye mota dzemagetsi.
Nzvimbo dzekushandisa dzelithium mabhatirivanonyanya kukamurwa kuva simba uye vasiri simba. Iwo masimba emagetsi e lithium-ion bhatiri application anosanganisira mota dzemagetsi, maturusi emagetsi, nezvimwe; minda isina-simba inosanganisira zvemagetsi zvevatengi uye minda yekuchengetedza simba, nezvimwe.
Kuumbwa uye kupatsanurwa kwe lithium mabhatiri
Lithium mabhatiri anonyanya kuumbwa nezvikamu zvina: positive electrode zvinhu, negative electrode zvinhu, electrolytes uye bhatiri separators. Negative electrode zvinhu zvinonyanya kukanganisa kushanda kwekutanga uye kutenderera kuita kwe lithium-ion mabhatiri. Lithium bhatiri negative electrodes inonyanya kukamurwa kuita mapoka maviri: kabhoni zvinhu uye zvisiri kabhoni zvinhu. Chishandiso chakanyanya kutariswa pamusika ndeye graphite negative electrode zvinhu pakati pekabhoni zvinhu, pakati peiyo yekugadzira graphite uye yechisikigo graphite ine yakakura-chikuru maindasitiri ekushandisa. Silicon-based negative electrode ndiyo inotarisa kutsvagisa nevagadziri vakuru vemagetsi emagetsi uye ndeimwe yezvinhu zvitsva zvisina kunaka zve electrode izvo zvinonyanya kushandiswa pamwero mukuru mune ramangwana.
Lithium mabhatirivanoiswa mu lithium cobalt oxide mabhatiri, lithium iron phosphate mabhatiri, ternary mabhatiri, etc. maererano neyakanaka electrode zvinhu;
Zvinoenderana nechimiro chechigadzirwa, iwo akakamurwa kuita masikweya mabhatiri, cylindrical mabhatiri uye soft-pack mabhatiri;
Zvinoenderana nemamiriro ekushandisa, anogona kukamurwa kuita zvemagetsi zvevatengi, kuchengetedza simba uye mabhatiri emagetsi. Pakati pavo, mutengi lithium mabhatiri anonyanya kushandiswa muzvigadzirwa zve 3C; mabhatiri ekuchengetedza simba anonyanya kushandiswa mukuchengetedza simba reimba uye kugovera yakasununguka simba rekuchengetedza simba rekuchengetedza simba sezuva uye simba rekugadzira simba remhepo; mabhatiri emagetsi anonyanya kushandiswa mumotokari dzakasiyana-siyana dzemagetsi, maturusi emagetsi uye motokari itsva dzesimba.
Mhedziso
Heltec icharamba ichivandudza ruzivo rwakakurumbira rwesainzi nezvelithium mabhatiri. Kana iwe uchifarira, iwe unogona kuiteerera. Panguva imwecheteyo, tinokupa iwe yepamusoro-mhando lithium bhatiri mapaketi kuti iwe utenge uye upe masevhisi akagadziridzwa kuti asangane nezvido zvako.
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. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa, uye kudyidzana kwakasimba kwevatengi kunotiita isu kuenda-kune sarudzo yevagadziri vebhatiri pack uye vatengesi pasi rese.
Kana uine chero mibvunzo kana uchida kudzidza zvakawanda, ndapota usazezasvika kwatiri.
