Izi zimasintha mawonekedwe a crystalline mkati mwa batri, kuonjezera kukana kwamkati ndi kuchepetsa mphamvu pakapita nthawi. Ngakhale ndizocheperako kuposa mabatire a nickel-cadmium (NiCd), kukumbukira kumakhudzabe magwiridwe antchito a NiMH.
Kudziletsa ndi nkhani ina. Maselo okalamba amapanga makristasi akuluakulu ndi kukula kwa dendritic, zomwe zimawonjezera kusokoneza mkati. Izi zimabweretsa kuchulukira kwamadzimadzi, makamaka pamene ma elekitirodi otupa amatulutsa mphamvu pa electrolyte ndi olekanitsa.

|---|---|
| Memory Mmene | Kubwereza kocheperako kumasintha mawonekedwe a crystalline, kuchepetsa mphamvu. |
| Kudziletsa | Maselo okalamba ndi ma electrode otupa amawonjezera kuchuluka kwamadzimadzi. |
Mavutowa amapangitsa kuti mabatire a NiMH asakhale oyenerera ku mapulogalamu omwe amafunikira kusungidwa kwa nthawi yayitali kapena kugwira ntchito kwapamwamba kosasinthasintha. Kusamalira moyenera, monga kutulutsa batire nthawi ndi nthawi, kumatha kuchepetsa izi.
Zovuta zachitetezo cha batri ya lithiamu
Mabatire a lithiamu, ngakhale kuti imagwira ntchito bwino, imakhala ndi chiopsezo chachikulu cha chitetezo. Kuthamanga kwa kutentha, chifukwa cha kutentha kwambiri kapena maulendo afupiafupi, kungayambitse moto kapena kuphulika. Tinthu tating'ono ting'onoting'ono tachitsulo mkati mwa batire titha kuyambitsa mabwalo amfupi, ndikuwonjezera chiopsezo. Opanga atengera njira zowonera kuti athetse vutoli, koma zochitika zikuchitikabe.
Kukumbukira kwa mapaketi pafupifupi mamiliyoni asanu ndi limodzi a lithiamu-ion omwe amagwiritsidwa ntchito m'makompyuta akuwunikira kuwopsa kwake. Ngakhale kulephera kwa m'modzi mwa 200,000, kuthekera kovulaza kumakhalabe kwakukulu. Zolephera zokhudzana ndi kutentha zimakhudzidwa makamaka, makamaka pazinthu zogula ndi magalimoto amagetsi.

Ziwerengerozi zikugogomezera kufunika kotsatira ndondomeko zachitetezo pogwiritsa ntchito mabatire a lithiamu.
Zovuta zina wamba
Mabatire onse a NiMH ndi lithiamu amagawana zovuta zina. Zinthu zolemetsa kwambiri zimachepetsa magwiridwe antchito awo, ndipo kusungidwa kosayenera kumatha kufupikitsa moyo wawo. Mabatire a NiMH ndi ochulukirapo komanso olemera kwambiri, akuchepetsa kugwiritsa ntchito kwawo pazida zonyamula. Mabatire a lithiamu, ngakhale opepuka, ndi okwera mtengo ndipo amafunikira njira zapamwamba zobwezeretsanso kuti achepetse kuwonongeka kwa chilengedwe.
Ogwiritsa ntchito ayenera kuyeza izi potengera zomwe apeza posankha mtundu wa batri pazosowa zawo zenizeni.
Kusankha pakati pa mabatire a NiMH ndi lithiamu omwe amatha kuchajitsidwanso kumatengera zomwe wogwiritsa ntchito amaika patsogolo komanso zosowa zake. Mabatire a NiMH amapereka kutsika mtengo, chitetezo, komanso kubwezeretsedwanso, kuwapanga kukhala abwino pamagetsi apanyumba ndi magetsi ongowonjezwdwa.Mabatire a lithiamu, ndi mphamvu zawo zochulukirapo, moyo wautali wozungulira, komanso kuthamanga kwachangu, zimapambana pa ntchito zogwira ntchito kwambiri monga magalimoto amagetsi ndi zamagetsi.
