Zvinoenderana neakasiyana emagetsi emagetsi anoshandiswa mumabhatiri e-lithium ion, mabhatiri e-lithium ion akakamurwa kuita mabhatiri e-lithium ion (Liquified Lithium-Ion Battery, inonzi LIB) uye Polymer Lithium-Ion mabhatiri (akapfupikiswa sePLB).

Lithium ion bhatiri (Li-ion)

Rechargeable lithium-ion bhatiri parizvino ndiro bhatiri rinoshandiswa zvakanyanya muzvigadzirwa zvemazuva ano zvedhijitari senge mbozhanhare nemakomputa ekunyorera, asi yakanyanya “kunyungudika” uye haigone kukwirisa kana kudhizairwa panguva yekushandiswa (ichakuvadza bhatiri kana kuita kuti rive. scrapped). Naizvozvo, pane zvinodzivirira kana maseketi anodzivirira pabhatiri kudzivirira kudhura kwebhatiri kukuvara. Lithium-ion bhatiri yekuchaja zvinodiwa zvakakwira zvakanyanya. Kuti ive nechokwadi chekuti kupera kwevoltage kurongeka kuri mukati me ± 1%, vagadziri vakuru vemichina yesemiconductor vakagadzira akasiyana-siyana e-lithium-ion bhatiri yekuchaja ICs kuve nechokwadi chakachengeteka, chakavimbika, uye nekukurumidza kuchaja.

Nharembozha dzinoshandisa lithium-ion mabhatiri. Kushandisa zvakanaka mabhatiri e-lithium-ion kwakakosha kuti uwedzere hupenyu hwebhatiri. Inogona kugadzirwa kuita flat rectangular, cylindrical, rectangular uye bhatani mhando zvinoenderana nezvinodiwa zveakasiyana zvigadzirwa zvemagetsi, uye ine bhatiri pack inoumbwa akati wandei mabhatiri munhevedzano uye yakafanana. Iyo yakayerwa voltage yebhatiri ye lithium-ion inowanzoita 3.7V nekuda kwekushanduka kwezvinhu, uye iri 3.2V yelithium iron phosphate (inozonzi ferrophosphorus). Mhepo yekupedzisira yekuchaja kana yazara inokwana 4.2V, uye ferrophosphorus i3.65V. Mhedzisiro yekuburitsa mabhatiri e-lithium-ion ndeye 2.75V～3.0V (fekitari yebhatiri inopa vhezheni yekushanda kana iyo yekupedzisira yekuburitsa voltage, ma paramita akasiyana zvishoma, kazhinji 3.0V, uye phosphorus iron 2.5V). Kuramba kuchibuda pazasi pe2.5V (ferro-phosphorus 2.0V) kunonzi over-discharge, uye kuburitsa zvakanyanya kunokuvadza bhatiri.

Lithium-ion mabhatiri ane lithium cobalt oxide mhando zvinhu seyakanaka electrode isingakodzeri kubuda kwepamusoro-ikozvino. Kuwedzerwa kwezvino kubuda kunoderedza nguva yekubuda (kupisa kwepamusoro mukati uye kurasikirwa kwesimba) uye inogona kuva nengozi; asi lithium iron phosphate Iyo yakanaka electrode zvinhu lithium bhatiri inogona kuchajwa uye kuburitswa neyakakura ikozvino ye20C kana kupfuura (C ndiko kugona kwebhatiri, senge C = 800mAh, 1C yekuchaja chiyero, ndiko kuti, yekuchaja ikozvino 800mA. ), iyo inonyanya kukodzera motokari dzemagetsi. Naizvozvo, fekitori yekugadzira bhatiri inopa yakanyanya kuburitsa ikozvino, iyo inofanirwa kunge iri shoma pane yakanyanya kuburitsa ikozvino panguva yekushandiswa. Lithium-ion mabhatiri ane zvimwe zvinodiwa pakupisa. Iyo fekitori inopa tembiricha yekuchaja, kuburitsa tembiricha yemhando uye tembiricha yekuchengetedza. Overvoltage kuchaja kuchakonzera kukuvara zvachose kune lithium-ion bhatiri. Ikozvino yekuchaja yemabhatiri e-lithium-ion inofanira kunge yakavakirwa pane zvinokurudzirwa zvemugadziri webhatiri, uye ikozvino-inoganhura dunhu inofanirwa kudikanwa kuti udzivise overcurrent (kupisa). Kazhinji, chiyero chekuchaja i0.25C～1C. Zvinowanzodikanwa kuona tembiricha yebhatiri panguva yekuchaja kwepamusoro kudzivirira kupisa kubva pakukuvadza bhatiri kana kukonzera kuputika.

Lithium-ion bhatiri yekuchaja yakakamurwa kuita nhanho mbiri: yekutanga inogara ichichaja ikozvino, uye ichichinjika kune inogara ichichaja voltage kana yave pedyo nekumisa voltage. Semuenzaniso, bhatiri rine huwandu hwe800 mAh, yekupedzisira yekuchaja voltage ndeye 4.2V. Iyo bhatiri inochajirwa neiyo inogara iripo ye800mA (yero yekuchaja ye1C). Pakutanga, bhatiri voltage inokwidziridzwa nemateru makuru. Kana iyo bhatiri voltage iri pedyo ne4.2V, inoshandurwa kuita 4.2V inogara ichichaja. Ikozvino inodonha zvishoma nezvishoma uye voltage inochinja zvishoma. Kana iyo yekuchaja yazvino inodonha kusvika 1/10-50C (yakasiyana magadzirirwo efekitori, haina kukanganisa kushandiswa), inoonekwa sepedyo nekuchaja yakazara, uye kuchaja kunogona kugumiswa (mamwe machaja anotanga iyo timer mushure me1/10C. , mushure meimwe nguva yenguva Kupera kwekuchaja).
