Lithium bhatiri (Li-ion, Lithium Ion Bhatiri): Lithium-ion mabhatiri ane mabhenefiti ehuremu huremu, huremu hwepamusoro, uye hapana mhedzisiro yekurangarira, uye nekudaro anowanzoshandiswa - mazhinji edhijitari mabhatiri anoshandisa lithium-ion mabhatiri sesimba remagetsi, kunyangwe iwo ari kudhura. Iyo simba density yemabhatiri e-lithium-ion yakakura kwazvo, uye huwandu hwayo hunosvika 1.5 kusvika ku2NiMH mabhatiriyehuremu hwakafanana, uye ine mwero wakaderera kwazvo wekuzviburitsa. Mukuwedzera, mabhatiri e-lithium-ion ane anenge asina "memory effect" uye haana zvinhu zvine chepfu uye zvimwe zvakanakira zvakare chikonzero chakakosha chekushandiswa kwakapararira. Ndapota cherechedzawo kuti mabhatiri e lithium anowanzoiswa 4.2V lithiumion bhatiri kana 4.2V lithium yechipiri bhatiri kana 4.2V lithiumion rechargeable bhatiri kunze.

18650 lithium bhatiri
18650 ndiye muvambi we lithium-ion bhatiri - ndeye standard lithium-ion bhatiri modhi yakaiswa nekambani yeJapan SONY kuitira kuchengetedza mari, 18 inoreva dhayamita 18mm, 65 inoreva kureba kwe65mm, 0 inoreva cylindrical bhatiri. 18650 zvinoreva, 18mm dhayamita, 65mm kureba. Uye nhamba yemuenzaniso weNo. 5 bhatiri ndeye 14500, 14 mm muhupamhi uye 50 mm kureba. General 18650 bhatiri rinoshandiswa zvakanyanya muindasitiri, kushandiswa kwevagari kushoma, kunowanzoshandiswa mumabhatiri elaptop uye matochi ekupedzisira.

Yakajairwa 18650 mabhatiri akakamurwa kuita lithium-ion mabhatiri, lithium iron phosphate mabhatiri. Lithium-ion bhatiri voltage yezita remagetsi e3.7v, kuchaja yakachekwa-kubvisa voltage ye4.2v, lithium iron phosphate bhatiri nominal voltage ye3.2V, kuchaja cut-off voltage ye3.6v, simba rinowanzoita 1200mAh-3350mAh, yakajairika. iri 2200mAh-2600mAh. 18650 lithium bhatiri hupenyu dzidziso yekutenderera kubhadharisa ka1000 nguva.

18650 Li-ion bhatiri rinonyanya kushandiswa mumabhatiri elaptop nekuda kwehuwandu hwayo hwepamusoro per unit density. Pamusoro pezvo, 18650 Li-ion bhatiri rinoshandiswa zvakanyanya muminda yemagetsi nekuda kwekugadzikana kwayo kwakanyanya pabasa: inowanzoshandiswa mugiredhi remwenje tochi, inotakurika magetsi, isina waya data transmitter, magetsi anodziya mbatya uye shangu, inotakurika zviridzwa, inotakurika mwenje michina. , purinda inotakurika, zviridzwa zveindasitiri, zviridzwa zvekurapa, nezvimwe midziyo yekurapa, nezvimwe.

Li-ion bhatiri rakanyorwa 3.7V kana 4.2V zvakafanana. 3.7V inoreva voltage yepapuratifomu (kureva, chaiyo voltage) panguva yekushandiswa kwebhatiri kubuda, nepo 4.2 volts inoreva voltage pakuchaja yakazara. Common rechargeable 18650 lithium bhatiri, voltage yakanyorwa 3.6 kana 3.7v, 4.2v kana yazara, isingaite nesimba (capacity), 18650 bhatiri mainstream capacity kubva 1800mAh kusvika 2600mAh, (18650 simba bhatiri huwandu huzhinji mu2200 ~ 2600mAh), iyo mainstream chiyero inotonyorwa 3500 kana 4000mAh kana kupfuura iripo.

Zvinowanzotendwa kuti hapana-mutoro voltage yeLi-ion bhatiri ichave iri pasi pe3.0V uye magetsi achashandiswa kumusoro (iyo chaiyo kukosha inoda kutsamira pachikumbaridzo kukosha kwebhatiri kuchengetedza bhodhi, semuenzaniso, kune yakaderera se2.8V, kune zvakare 3.2V). Mazhinji mabhatiri e-lithium haagone kuburitswa kune-no-load voltage ye3.2V kana yakaderera, zvikasadaro kubuda kwakanyanya kunokuvadza bhatiri (iyo general market lithium mabhatiri anonyanya kushandiswa nendiro yekudzivirira, saka kubuda kwakanyanya kunotungamira kune ndiro yekudzivirira. haikwanise kuona bhatiri, saka haikwanise kuchaja bhatiri). 4.2V ndiyo inogumira bhatiri yekuchaja voltage, inowanzoonekwa seye-no-load voltage yelithium bhatiri inochajwa kusvika ku4.2V pamagetsi Yakazara, bhatiri yekuchaja maitiro, bhatiri voltage pa 3.7V zvishoma nezvishoma inokwira kusvika 4.2V, lithium. Kuchaja kwebhatiri hakugone kubhadhariswa kupfuura 4.2V isina-load voltage, zvikasadaro ichakuvadza bhatiri, iyo inzvimbo yakakosha yebhatiri ye lithium.

Zvakanakira

1. Hombe inokwana 18650 lithium bhatiri huwandu hunowanzo pakati pe1200mah ~ 3600mah, nepo huwandu hwebhatiri hunogona kungosvika 800mah, kana yakabatanidzwa mu18650 lithium bhatiri pack, iyo 18650 lithium bhatiri pack inongove inogona kupaza ne5000mah.

2. Hupenyu hurefu 18650 lithium bhatiri hupenyu hwakareba kwazvo, iyo yakajairika kushandiswa kwehupenyu hwekutenderera kusvika ku500 nguva, inodarika kaviri bhatiri rakajairwa.

3. Yakakwirira kuchengetedza kushanda 18650 lithium bhatiri kuchengetedza kushanda, kuitira kudzivirira bhatiri pfupi pfupi chiitiko, 18650 lithium battery positive uye matanda asina kunaka anoparadzaniswa. Saka mukana wekupfupika wedunhu wakaderedzwa kusvika pakunyanyisa. Iwe unogona kuwedzera ndiro yekudzivirira kuti udzivise kuwandisa uye kudhiza bhatiri, izvo zvinogona zvakare kuwedzera hupenyu hwebasa rebhatiri.

4. High voltage 18650 lithium battery voltage inowanzosvika pa 3.6V, 3.8V uye 4.2V, yakakwirira kudarika 1.2V voltage yeNiCd neNiMH mabheteri.

5. Hapana mhedzisiro yekurangarira Hapana chikonzero chekudurura simba rasara usati wachaja, nyore kushandisa.

6. Kupikiswa kwemukati diki: Kupikiswa kwemukati kwemasero epolymer kudiki pane kwesero remvura masero, uye kupikisa kwemukati kwemasero emudzimba epolymer kunogona kutopfuura 35mΩ, izvo zvinoderedza zvakanyanya kuzvishandisa kwebhatiri uye kuwedzera nguva yekumira. nharembozha, uye inogona kusvika zvachose padanho repasi rose. Iyi mhando yepolymer lithium bhatiri inotsigira yakakura yekuburitsa ikozvino yakanakira mamodhi ekudzora kure, ichiva iyo inovimbisa imwe nzira kune NiMH mabhatiri.
