Kuunzwa kweAnode uye Cathode Material yeLithium Ion Bhatiri

Kana iri lithium bhatiri uye lithium ion bhatiri (lithium polymer bhatiri zvakare ndeye lithium ion bhatiri), lithium bhatiri ibhatiri rinoshandisa lithium simbi kana lithium alloy se cathode zvinhu. Iyo kemikari yemhando yelithium simbi inoshanda zvakanyanya, zvekuti iyo lithium simbi inoda zvakanyanya kuomarara zvinodiwa pane zvakatipoteredza pakuita kwayo, kuchengetedza uye kushandiswa. Iyo cathode zvinhu zve lithium ion bhatiri inopindirana dhizaini senge kabhoni. Lithium ion bhatiri yakachengeteka nekuti chete Li ion inofambisa pakati peanode uye cathode mukati mebhatiri. Kana iri lithium ion bhatiri uye lithium polymer bhatiri, iyo electrolyte ye lithium ion bhatiri inzvimbo yemvura, nepo iyo yelithium polymer bhatiri iri gel kana yakasimba mamiriro, ayo anoita kuti bhatiri risachengeteke.

Kutanga

Iri zita resainzi reti lithium ion bhatiri ndiro lithium yechipiri bhatiri, ine inowirirana cathode zvinhu. Yakasiyana kubva yekutanga lithium bhatiri maererano ne lithium se electrode imwe, lithium yechipiri bhatiri imvura electrolyte iyo inosanganisa LiPF6 neLiClO4 mu electrolyte yeDMC:EC(v:v=1:1). Imwe electrolyte ine shanduko, asi lithium yechipiri bhatiri ichiri bhatiri remvura.

Mukutaura kwemukati mezvinhu zve lithium polymer bhatiri, electrolyte yayo ipolymer, kazhinji igel electrolyte uye yakasimba electrolyte. South Korean inovamba gel bhatiri nePEO-ion se electrolyte. Hazvizivikanwe kana kune rudzi urwu rwebhatiri muGalaxyRound kana LGGFlex.

Chechipiri

Pane mimwe misiyano pasuru pakati pe lithium polymer bhatiri uye lithium bhatiri. Lithium bhatiri ine simbi shell package (18650 kana 2320), ukuwo lithium polymer bhatiri rakaiswa nealuminium epurasitiki yekurongedza firimu, iyo yakatumidza pouch cell.

Imwe lithium bhatiri ine yakazara yakasimba electrolyte, yakadai seLiPON, NASICON, perovskite, LiSICON, iyo ceramic electrolyte ine yakakwirira conductivity kana girazi electrolyte yakagadzirwa neamorphous substance. Inogona kunge iri yelithium yechipiri bhatiri.

Zvese mune zvese, lithium bhatiri inogona kukamurwa kuita mapoka maviri: lithium simbi bhatiri uye lithium ion bhatiri. Kazhinji, lithium simbi bhatiri haichajiki nesimbi lithium, nepo lithium ion bhatiri haina simbi lithium asi inochajwa. Lithium bhatiri, lithium ion bhatiri uye lithium polymer bhatiri ine theoretical misiyano.
