Lithium polymer betri

lithium polymer betri

Betri ea lithium polymer ke mofuta oa betri e ka nchafatsoang ka mokhoa o monyane. Libetri tsena li loketse lisebelisoa tsa cellular tse hlokang ho feta 3 watts empa li le tlase ho 7 watts, joalo ka lilaptop le mehala ea cellular. Libetri tsa lithium polymer li ile tsa rehoa lebitso la motsoako oa li-ion tsa lithium le li-polymers (ntho e nang le limolek'hule tse kholo) tse etsang kaho ea tsona.

Betri ea lithium polymer e qapiloe mme e entsoe ke bafuputsi ho elella bofelong ba lilemo tsa bo-1980. Mohlala oa pele oa betri ea lithium polymer e ile ea hlahisoa ka 1994 bakeng sa ts'ebeliso ea tšohanyetso ea bongaka, 'me lilemo tse ka bang 10 ka mor'a hore e bōptjoe, e ile ea sebelisoa ho li-satellite le spacecraft. Betri ea lithium polymer e 'nile ea sebelisoa ka liselefouno ho tloha 2004, e leng nako eo Sony e ileng ea hlahisa mohala oa pele oa thelefono o rekisoang o sebelisa betri ea lithium ion.

Libetri tsa lithium polymer li fapane le libeteri tsa lithium ion hobane ha li na karohano lipakeng tsa li-electrode tse ntle le tse mpe. Li-polymer tse sebelisoang ka har'a libeteri tsena li na le ts'ebetso e ts'oanang le ea jelly, ke ka lebaka leo hangata li bitsoang lisele tsa gel. Libetri tsa lithium polymer le tsona li na le monyetla oa ho se be le monyetla oa ho ba le ho lutla ha electrolyte ha li bapisoa le mefuta e meng ea libeteri tsa lithium ion hobane ha ho na karohano e teng.

Kotsi ea ho lutla ha electrolyte e bile e hlaha ka mefuta e meng e seng ea lithium polymer. Le hoja betri e tšoana ka ponahalo le libeteri tse ling tsa lithium ion, lisebelisoa tse sebelisoang ka hare ho eona li fapane le tsa li-betri tsa lithium ion tse tloaelehileng. Mokelikeli oa electrolyte o kopanyang li-terminals tse ntle le tse mpe ka har'a betri e tloaelehileng ea lithium ion e entsoe ka potassium hydroxide kapa lithium hydroxide, e sebetsanang le graphite ka electrode e ntle nakong ea ho tjhaja.

Karolo e 'ngoe ea betri ea lithium ion e sebetsang ke graphite, eo ka karabelo ea lik'hemik'hale e nang le electrolyte e theha boima bo tiileng bo bitsoang carbon dioxide pentoxide, e sebetsang e le insulator. Leha ho le joalo, ka betri ea lithium polymer, electrolyte e entsoe ka poly(ethylene oxide) le poly(vinylidene fluoride), kahoo ha ho hlokahale graphite kapa mofuta ofe kapa ofe oa carbon. Li-polymers ke lisebelisoa tse nang le limolek'hule tse kholo, tse khonang ho hanela mocheso o phahameng le ho senya ho itseng.

Li-polymers tse sebelisoang ka har'a libeteri tsa lithium polymer li fana ka thepa e hlahisang sebopeho se kang sa gel ha se bapisoa le mefuta e meng ea libeteri tsa lithium ion. Electrolyte e entsoe ka motsoako oa lintho tse phelang o ka etsoang ntle le lithium, kahoo e fetoha mofuta o theko e boima ka ho fetisisa oa betri.

Libetri tsa lithium polymer li sebelisoa lits'ebetsong tse ngata hobane li tenyetseha ebile li khona ho mamella mocheso o phahameng ho feta mefuta e meng ea libeteri tsa lithium ion. Li boetse li na le boima ba 'mele bo fokolang ho feta ba pele ho tsona, e leng se lumellang mosebedisi ho tšoara selefouno nako e telele ntle le ho utloa bohloko kapa ho utloa bohloko matsohong le matsoho.
