Libetri tsa lithium ke eng, 'me li sebetsa joang?

Libetri tsa lithium ion ke life, li entsoe ka eng le melemo efe ha e bapisoa le mahlale a mang a polokelo ea betri?

Ea pele e hlahisitsoeng lilemong tsa bo-1970 mme e hlahisoa khoebong ke Sony ka 1991, libeteri tsa lithium li se li sebelisoa ka mehala ea cellular, lifofane le likoloi.Leha ho na le melemo e mengata e ba lebisitseng katlehong e ntseng e eketseha indastering ea matla, libeteri tsa lithium ion li na le mathata 'me ke taba e tsosang lipuisano tse ngata.

Libetri tsa lithium li entsoe ka eng?

Betri ea lithium e entsoe ka likarolo tse 'nè tsa bohlokoa.E na le cathode, e khethollang matla le matla a betri mme ke mohloli oa li-ion tsa lithium.Anode e etsa hore motlakase o phalle ka potoloho ea kantle 'me ha betri e qosoa, li-ion tsa lithium li bolokiloe ho anode.

Melemo le likotsi tsa libeteri tsa lithium

Libetri tsa lithium li na le matla a phahameng haholo ho feta libeteri tse ling.Li ka ba le matla a fihlang ho 150 watt-horas (WH) ka kilogram (kg), ha e bapisoa le libeteri tsa nickel-metal hydride tse ho 60-70WH/kg le tsa lead tse nang le asiti ea lead ho 25WH/kg.

Ba boetse ba na le sekhahla se tlase sa ho tsoa ho feta ba bang, ba lahleheloa ke hoo e ka bang 5% ea tefiso ea bona ka khoeli ha ba bapisoa le libeteri tsa nickel-cadmium (NiMH) tse lahleheloang ke 20% ka khoeli.

Leha ho le joalo, libeteri tsa lithium li boetse li na le electrolyte e tukang e ka bakang mollo o monyane oa betri.Sena ke sona se bakileng ho chesoa ha li-smartphone tse tummeng hampe tsa Samsung Note 7, tse ileng tsa qobella Samsung ho lahla tlhahiso le.lahleheloa ke $ 26bn ka boleng ba 'maraka.Hoa lokela ho hlokomeloa hore sena ha se e-s'o etsahale ka libeteri tse kholo tsa lithium.

Libetri tsa lithium-ion le tsona li theko e boima haholo ho li etsa, kaha li ka bitsa chelete e kaalo 40% ho feta ho hlahisa libeteri tsa nickel-cadmium.
