Kuyamba Kwa Anode Ndi Cathode Material A Lithium Ion Battery

Ponena za batri ya lithiamu ion ndi batri ya lithiamu ion (batire ya lithiamu polima imakhalanso ya batri ya lithiamu ion), batri ya lithiamu ndi batri yogwiritsira ntchito lithiamu zitsulo kapena lithiamu alloy ngati zinthu za cathode. Chikhalidwe chamankhwala cha lithiamu chitsulo chimagwira ntchito kwambiri, kotero kuti zitsulo za lithiamu zimafunikira zofunikira kwambiri pa chilengedwe chifukwa cha ndondomeko yake, kusungirako ndi kugwiritsa ntchito. The cathode chuma cha lithiamu ion batire ndi intercalated dongosolo zinthu monga mpweya. Batire ya Lithium ion ndiyotetezeka chifukwa Li ion imatumiza pakati pa anode ndi cathode mkati mwa batire. Koma lithiamu ion batire ndi lifiyamu polima batire, electrolyte ya lithiamu ion batire ndi yamadzimadzi, pamene ya lithiamu polima batire ndi gel osakaniza kapena olimba, zomwe zimapangitsa batire kukhala otetezeka.

Choyamba

Dzina lasayansi la batire ya lithiamu ion ndi batri yachiwiri ya lithiamu, yokhala ndi zida zofananira za cathode. Osiyana ndi batire yoyamba ya lithiamu ponena za lithiamu ngati elekitirodi imodzi, batire yachiwiri ya lithiamu ndi electrolyte yamadzimadzi yomwe imaphatikiza LiPF6 ndi LiClO4 mu electrolyte ya DMC:EC(v:v=1:1). Electrolyte ina imasinthidwa, koma batire yachiwiri ya lithiamu ikadali batri yamadzi.

Pazinthu zamkati za batri ya lithiamu polima, electrolyte yake ndi polima, nthawi zambiri ndi gel electrolyte ndi electrolyte yolimba. South Korea yapanga batire ya gel ndi PEO-ion ngati electrolyte. Sizikudziwika ngati pali batire yamtunduwu mu GalaxyRound kapena LGGFlex.

Chachiwiri

Pali kusiyana pakati pa batire ya lithiamu polima ndi batire ya lithiamu. Lithium batire ali zitsulo chipolopolo phukusi (18650 kapena 2320), pamene lithiamu polima batire mmatumba ndi zotayidwa pulasitiki ma CD filimu, amene dzina thumba cell.

Batire ina ya lithiamu imakhala ndi electrolyte yolimba, monga LiPON, NASICON, perovskite, LiSICON, electrolyte ya ceramic yokhala ndi ma conductivity apamwamba kapena magalasi a electrolyte opangidwa ndi amorphous substance. Itha kukhala ya batri yachiwiri ya lithiamu.

Zonsezi, batri ya lithiamu ikhoza kugawidwa m'magulu awiri: batri ya lithiamu zitsulo ndi batri ya lithiamu ion. Nthawi zambiri, batri ya lithiamu chitsulo sichikhoza kubwerezedwanso ndi zitsulo za lithiamu, pamene batri ya lithiamu ion ilibe zitsulo zachitsulo koma imatha kuwonjezeredwa. Batire ya lithiamu, batri ya lithiamu ion ndi batri ya lithiamu polymer ili ndi kusiyana kwamalingaliro.
