Mabhatiri anouya mumakemikari akasiyana siyana nemhando, aine maviri anonyanya kufarirwa anogona kuchajwa ari Li-ion (lithium-ion) bhatiri uye NiMH (nickel-metal hydride) bhatiri.Kunyange ivo vachigovana mamwe maitiro akafanana, Li-ion bhatiri uye NiMH bhatiri vane akati wandei misiyano yakakosha inoita kuti ive yakakodzera kune akasiyana maapplication.Kunzwisisa misiyano iyi kunogona kukubatsira kuti usarudze tekinoroji yebhatiri chaiyo.
Energy Density: Chinhu chakakosha pakusarudza kwebhatiri isimba remagetsi, rinoyerwa muwatt-maawa pakirogiramu (Wh/kg).Lithium mabhatiri anopa simba rakanyanya kusimba kupfuura mabhatiri eNiMH.Semuenzaniso, yakajairwa lithium-ion bhatiri inopa yakatenderedza 150-250 Wh/kg, ichienzaniswa neyakakomberedza 60-120 Wh/kg yeNiMH.Izvi zvinoreva kuti lithium mabhatiri anogona kurongedza simba rakawanda munzvimbo yakareruka uye diki.Izvi zvinoita kuti lithium bhatiri rive rakanakira kugonesa compact elektroniki zvishandiso kana mota dzemagetsi.Mabhatiri eNiMH akakura asi achiri kubatsira kune maapplication uko saizi diki isiri yakakosha.
Charge Capacity: Mukuwedzera kune simba rakakwirira, mabhatiri e-lithium-ion anopawo simba guru rekuchaja kupfuura mabhatiri eNiMH, anowanzoonekwa pa 1500-3000 mAh ye lithium vs. 1000-3000 mAh yeNiMH.Iyo yakakwira yekuchaja huwandu inoreva kuti mabhatiri e lithium anogona magetsi ekushandisa kwenguva yakareba pachaji imwe chete kana ichienzaniswa neNiMH.Nekudaro, mabhatiri eNiMH achiri kupa nguva yakareba yakakwana yekumhanya kune mazhinji evatengi emagetsi uye maturusi emagetsi.
Mutengo: Panyaya yemutengo wepamberi, mabhatiri eNiMH anowanzo kuchipa kupfuura lithium-ion mabhatiri.Nekudaro, mabhatiri e-lithium ane simba rakanyanya density, saka unoda mashoma e-lithium maseru kuti ape simba mudziyo, izvo zvinoderedza mutengo.Mabhatiri eLithium ane zvakare hupenyu hurefu, aine mamwe achichengeta kusvika ku80% yekugona kwavo mushure memazana mashanu ekuchajisa.Mabhatiri eNiMH anongogara 200-300 mabhatiri asati adonha kusvika ku70%.Saka, nepo NiMH inogona kunge iine mutengo wakaderera wekutanga, lithiamu inogona kuve inodhura-inoshanda mukufamba kwenguva.
Kuchaja: Musiyano wakakosha mukuchaja kweaya mabhatiri marudzi maviri ndeokuti lithium-ion mabhatiri ane zvishoma kana pasina charge memory effect, kusiyana nemabhatiri eNiMH.Izvi zvinoreva kuti mabhatiri e-lithium anogona kuburitswa pamwe nekuchajwa kakawanda pasina kukanganisa kushanda kana hupenyu hwebhatiri.NeNiMH, zvakanakisa kuburitsa uye kuzadzazve bhatiri kuti udzivise kuchaja ndangariro, iyo inogona kuderedza huwandu nekufamba kwenguva.Lithium mabhatiri zvakare anowanzo kuchaja nekukurumidza, kazhinji mumaawa maviri kusvika mashanu, maringe nemaawa matatu kusvika manomwe kumabhatiri mazhinji eNiMH.
Environmental Impact: Nezve kushamwaridzana kwezvakatipoteredza, NiMH ine zvimwe zvakanakira pane lithium.Mabhatiri eNiMH anongova nezvinhu zvakapfava zvine muchetura uye asina simbi inorema, zvichiita kuti asanyanya kukuvadza nharaunda.Iwo zvakare anonyatso shandiswa zvakare.Lithium mabhatiri, kune rumwe rutivi, ane chepfu inorema simbi yakadai selithium simbi, cobalt, uye nickel makomisheni, inoisa njodzi yekuputika kana yakanyanyisa, uye parizvino ine mashoma mashoma ekudzokorodza sarudzo.Nekudaro, mabhatiri e lithium ari kuramba achienderera mberi sezvo tekinoroji nyowani dzebhatiri dzinobuda.
