NiMH mabhatiri

Ni-MH bhatiri inoumbwa nehydrogen ion uye metallic nickel. Simba rayo rekuchengetedza i30% kupfuura iro renickel-cadmium mabhatiri. Iyo yakareruka kupfuura nickel-cadmium mabhatiri, ine hupenyu hurefu hwesevhisi, ine yakakura kusvibiswa kwezvakatipoteredza, uye haina mhedzisiro yekurangarira. Izvo zvakashata zve nickel metal hydride mabhatiri ndeyekuti nickel cadmium mabhatiri anodhura kupfuura lithium mabhatiri.

lithium battery

Lithium bhatiri bhatiri rakagadzirwa naThomas Edison. Inoshandisa lithium simbi kana lithium alloy seyakanaka electrode zvinhu uye inoshandisa isiri-aqueous electrolyte mhinduro. Batiri kushanda kuita equation ndeye Li+MnO2=LiMnO2. Mhedzisiro yacho yakakamurwa kuita oxidation-reduction reaction uye discharge reaction. Munguva yakapfuura, mabhatiri e-lithium haana kushandiswa zvakanyanya nekuda kwemaitiro avo emakemikari akasiyana-siyana, zvinodiwa zvakanyanya pakugadzirisa, kuchengetedza uye kushandiswa, uye zvinodiwa zvakanyanya kune zvakatipoteredza. Nekuvandudzwa kwesainzi yemazuva ano, mabhatiri e-lithium ave ari makuru.

vhorumu

Kuenzaniswa neyakajairwa nickel-cadmium/nickel-metal hydride mabhatiri, rechargeable lithium mabhatiri ane mabhenefiti ehukuru hudiki (zvinei), huremu huremu, hushoma hwekuzviburitsa, hapana mhedzisiro yekuyeuka, nezvimwewo, uye akashandiswa zvakanyanya mune zvakawanda zvitsva. nharembozha. Mabhatiri eLithium akachinja zvishoma nezvishoma mabhatiri mumidziyo inotakurika senharembozha, makomputa ekunyorera, uye makomputa anobatwa nemaoko. Iyo yekurangarira mhedzisiro yenickel simbi hydride bhatiri haina kunyatso kuoneka. Chinhu chimwe ndechekuti inodiwa nekukurumidza uye haidi kubhadhariswa nephotoelectric. Kazhinji, zviri nani mushure mechiedza chakakwana.

magetsi

Lithium bhatiri ine yakakwira chaiyo simba uye kuita kwakanaka kwebhatiri. Mhepo yebhatiri reti lithium yakapetwa katatu iyo yenickel-metal hydride bhatiri. Iko hakuna kurangarira mhedzisiro, inogona kushandiswa uye kubhadharwa. Asi haigone kushandiswa pakuchaja, saka kuchaja nekuburitsa zvakawandisa kunokanganisa hupenyu hwebhatiri. Lithium mabhatiri haana kukodzera kuchengetedza kwenguva refu, uye kuchengetedza kwenguva refu kucharasikirwa zvachose chikamu chekugona kwavo. Zviri nani kubhadharisa 40% magetsi uye kuichengeta mufiriji yefiriji.

Kutengesa nzira

Zvinodiwa zvekuchaja mabhatiri e-lithium zvakasiyana nemabhatiri e-ni-CD/ni-MH, mabhatiri e-ni-CD/ni-MH anochajwazve mabhatiri e-lithium ane simba rimwechete re3.6V (mamwe mabhatiri anogona kunzi 3.7V). Sezvo simba rinowedzera, simba reti lithium bhatiri rinowedzera zvishoma nezvishoma, iyo iriwo chiratidzo chekuona kana lithium battery yakawandisa. Mugadziri mukuru anokurudzira kuchaja voltage ye4.2V (rimwe lithium bhatiri). Kazhinji kutaura, mabhatiri e lithium anochajwa nekudzikamisa voltage uye ikozvino. Kana iwe uchida kuchaja bhatiri reti lithium zvakasiyana, zvinofanirwa kucherechedzwa kuti nzira yekuchaja yakasiyana neyagara iripo yekuchaja nzira yenickel-cadmium/nickel metal hydride bhatiri, uye nickel-cadmium/nickel simbi hydride bhatiri charger haigone kuve. kushandiswa.
