Nhanganyaya:
Mabhatiri anogona kukamurwa zvakanyanya muzvikamu zvitatu: mabhatiri emakemikari, mabhatiri chaiwo uye mabhatiri ezvebhayoloji. Mabhatiri emakemikari ndiwo anonyanya kushandiswa mumotokari dzemagetsi.
Bhatiri remakemikari: Bhatiri remakemikari mudziyo unoshandura simba remakemikari kuita simba remagetsi kuburikidza nekuita kwemakemikari. Rine maelectrode akanaka neasina kunaka uye maelectrolyte.
Bhatiri remuviri: Bhatiri remuviri rinoshandura simba remuviri (rakadai sesimba rezuva nesimba remakanika) kuita simba remagetsi kuburikidza nekuchinja kwemuviri.
Kupatsanurwa kwemabhatiri emakemikari: Kubva pamaonero echimiro, anogona kukamurwa kuita mapoka maviri: mabhatiri ekuchengetera (kusanganisira mabhatiri ekutanga nemabhatiri echipiri) uye masero emafuta. Mabhatiri ekutanga: anogona kushandiswa kamwe chete, chinhu chinoshanda hachidzoreki, chinobuda chega chidiki, resistance yemukati yakakura, uye kugona kwehukuru hwakasiyana uye kugona kwehuwandu kwakakwira.
Mabhatiri echipiri: anogona kuchajwa uye kuburitswa kakawanda, chinhu chinoshanda chinogona kudzoserwa, uye anoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yekuchaja. Mazhinji emamodheru ari pamusika parizvino anoshandisa mabhatiri echipiri anogona kuchajwazve kutyaira mota. Mabhatiri echipiri akakamurwa kuita mabhatiri e lead-acid, mabhatiri e nickel-cadmium, mabhatiri e nickel-metal hydride uye mabhatiri e lithium zvichienderana nezvinhu zvakasiyana-siyana zve positive electrode. Parizvino, makambani emotokari ari mumusika anonyanya kushandisa mabhatiri e lithium, uye mashoma anoshandisa mabhatiri e nickel-metal hydride.
Tsanangudzo yebhatiri re lithiamu
Bhatiri reLithium ibheteri rinoshandisa lithium metal kana lithium alloy sezvinhu zvakanaka kana zvisina kunaka zveelectrode uye mhinduro ye electrolyte isina mvura.
Maitiro ekuchaja nekuburitsa simba rebhatiri re lithium anonyanya kutsamira pakufamba kwema ioni e lithium (Li+) pakati pema electrodes akanaka neasina kunaka. Pakuchaja, ma ioni e lithium anobviswa kubva pa electrode yakanaka oiswa mu electrode isina kunaka kuburikidza ne electrolyte, uye electrode isina kunaka inenge iri mu state ye lithium-rich; zvakapesana ndizvo zvinoitika kana ichichaja.
Electrochemical musimboti we lithium-ion battery
Fomura yemhinduro yakanaka yeelectrode: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Fomura yemhinduro yeelectrode isina kunaka: C + xLi + + xe- → CLix
Mabhatiri eLithium-ion ane simba rakawanda, anogara kwenguva refu uye haabudisi simba rakawanda, uye anoshandiswa zvakanyanya mumafoni, malaptop nemotokari dzemagetsi.
Nzvimbo dzekushandisa mabhatiri e lithium-ion dzakakamurwa kuva simba nedzisiri simba. Nzvimbo dzekushandisa mabhatiri e lithium-ion dzinosanganisira mota dzemagetsi, maturusi emagetsi, nezvimwewo; nzvimbo dzisiri simba dzinosanganisira magetsi emagetsi evatengi nenzvimbo dzekuchengetedza simba, nezvimwewo.
Kuumbwa uye kupatsanurwa kwemabhatiri e lithium
Mabhatiri eLithium-ion anonyanya kuumbwa nezvikamu zvina: zvinhu zve positive electrode, zvinhu zve negative electrode, electrolytes uye mabhatiri anoparadzanisa. Zvinhu zve negative electrode zvinonyanya kukanganisa kushanda kwekutanga uye mashandiro emabhatiri eLithium-ion. Ma electrode e negative bhatiri eLithium akakamurwa muzvikamu zviviri: zvinhu zvekabhoni nezvinhu zvisiri zvekabhoni. Chinonyanya kushandiswa pamusika i graphite negative electrode material pakati pezvinhu zvekabhoni, pakati pazvo graphite yekugadzira uye graphite yechisikigo ine mashandisirwo makuru emaindasitiri. Ma electrode ane negative akavakirwa paSilicon ndiwo anonyanya kutsvagurudzwa nevagadziri vema electrode ane negative uye ndeimwe yezvinhu zvitsva zve negative electrode zvinogona kushandiswa zvakanyanya mune ramangwana.
Mabhatiri eLithium-ion akapatsanurwa muzvikamu zve lithium cobalt oxide, lithium iron phosphate, mabhatiri eternary, nezvimwewo zvichienderana nezvinhu zvakanaka zve electrode;
Zvichienderana nechimiro chechigadzirwa, zvakakamurwa kuita mabhatiri akaenzana, mabhatiri e cylindrical uye mabhatiri akapfava;
Zvichienderana nemamiriro ekushandiswa, anogona kukamurwa kuita mabhatiri emagetsi evatengi, ekuchengetedza simba uye emagetsi. Pakati pawo, mabhatiri e lithiamu anoshandiswa zvakanyanya muzvigadzirwa zve3C; mabhatiri ekuchengetedza simba anonyanya kushandiswa mukuchengetedza simba remumba uye mukuchengetedza simba remagetsi akapararira akazvimiririra senge simba rezuva nekugadzira simba remhepo; mabhatiri emagetsi anonyanya kushandiswa mumotokari dzakasiyana dzemagetsi, maturusi emagetsi uye mota itsva dzemagetsi.
Mhedziso
Heltec icharamba ichivandudza ruzivo rwesainzi rwakakurumbira nezvemabhatiri e lithium. Kana uchida, unogona kuateerera. Panguva imwe chete, tinokupa mapaketi emabhatiri e lithium emhando yepamusoro kuti utenge uye tipe masevhisi akagadzirirwa iwe kuti aenderane nezvaunoda.
Heltec Energy ndiyo shamwari yako yaunovimba nayo mukugadzira mabheteri. Nekutarisa kwedu kutsvagurudzo nekuvandudza, pamwe chete nemidziyo yedu yakawanda yemabhatiri, tinopa mhinduro dzese kuti tisangane nezvinodiwa zviri kuchinja muindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa vatengi, uye hukama hwakasimba nevatengi zvinoita kuti tive sarudzo yakanaka kune vagadziri vemabheteri nevatengesi pasi rese.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
