Monyetla le Bobebe ba betri ea 18650 NMC le Li-Polymer lithium battery

 

“” e bolela tšebeliso ea li-polymers e le li-electrolyte, tse arotsoeng ka ho khetheha ka li-semi-polymers le li-polymers kaofela. Semi-polymer e bua ka ho roala polima (hangata PVDF) karohanong ho etsa hore betri e be thata le ho thatafatsa betri, ha electrolyte e ntse e le electrolyte ea mokelikeli.

“Polymer kaofela” e bolela tšebeliso ea polymer ho etsa marang-rang a gel ka hare ho betri, ebe o kenya electrolyte ho etsa electrolyte. Leha libetri tsohle tsa polymer li ntse li sebelisa li-electrolyte tsa metsi, ts’ebeliso ea tsona e fokotsehile haholo, e ntlafatsa haholo polokeho ea libeteri tsa lithium. Ho ea kamoo ke tsebang, ke Sony feela eo hajoale e hlahisang libeteri tsa lithium tsa polymer kaofela.

Ka lehlakoreng le leng, libeteri tsa polymer li bua ka libeteri tse sebelisang filimi ea polasetiki ea aluminium e le sephutheloana sa kantle sa libeteri tsa lithium, tse tsejoang hape e le li-soft-pack. Filimi ea ho paka e entsoe ka PP layer, Al layer le nylon layer. Hobane polypropylene le nylon ke li-polymers, lisele tsena li bitsoa lisele tsa polymer.

1. Theko e tlase

Theko ea machaba ea 18650 e ka bang $ 1 / PCS, ‘me theko ea 2Ah e ka bang 3 yuan / Ah. Theko e tlaase ea betri ea lithium ea polymer ke 4 yuan / Ah, theko ea bohareng ke 5-7 yuan / Ah, ‘me theko ea bohareng ke 7 yuan / Ah. Mohlala, ATL le molimo oa matla li ka rekisoa ka li-yuan tse 10/ah, empa batho bao u sa ba tsebeng ha ba batle ho li amohela.

2. Ha e khone ho etsoa ka mokhoa o ikhethileng

Sony e ntse e leka ho etsa libeteri tsa lithium tse tšoanang le libeteri tsa alkaline. 5 betri, che. Li-betri tse 7 lia tšoana lefatšeng ka bophara. Empa molemo oa bohlokoa oa libeteri tsa lithium ke hore li ka etsoa ho latela litlhoko tsa bareki, kahoo ha ho na maemo a tšoanang. Ho fihlela joale, ho na le mofuta o le mong feela o tloaelehileng oa 18650 indastering ea betri ea lithium, ‘me tse ling kaofela li etselitsoe ho fihlela litlhoko tsa bareki.

3. Tšireletseho e fokolang

Rea tseba hore tlas’a maemo a feteletseng (joalo ka tefiso e feteletseng, mocheso o phahameng, joalo-joalo), lik’hemik’hale tse mabifi tsa lik’hemik’hale li etsahala ka har’a betri ea lithium, e leng se etsang hore ho be le khase e ngata. Betri ea 18650 e na le k’hase ea tšepe e nang le matla a itseng. Ha khatello ea ka hare e fihla boemong bo itseng, khetla ea tšepe e tla phatloha ebe e phatloha, e leng se bakang likotsi tse tebileng tsa tšireletso.

Ke ka lebaka leo kamore eo betri ea 18650 e lekoang ho eona hangata e sirelelitsoeng ka thata ‘me e ke ke ea fumaneha nakong ea tlhahlobo. Libetri tsa polymer ha li na bothata bona. Esita le tlas’a maemo a tšoanang a feteletseng, ka lebaka la matla a tlaase a filimi ea ho paka, khatello e tla ba e phahameng hanyenyane feela, ho phatloha ho ke ke ha phatloha, ‘me boemong bo bobe ka ho fetisisa ho tla chesa. Libetri tsa polymer li bolokehile ho feta libeteri tse 18650.

4. Matla a fokolang a matla

Bokhoni bo tloaelehileng ba betri ea 18650 bo ka fihla ho 2200mAh, kahoo matla a matla a ka bang 500Wh/L, athe matla a betri ea polymer a ka ba haufi le 600Wh/L.

Empa libeteri tsa polymer le tsona li na le mefokolo ea tsona. Ntho ea bohlokoa ke litšenyehelo tse phahameng, hobane e ka etsoa ho latela litlhoko tsa bareki, ‘me litšenyehelo tsa lipatlisiso le nts’etsopele mona li tlameha ho kenyelletsoa. Ho feta moo, sebopeho se fetoha ‘me mefuta e mengata e pharaletseng. Lisebelisoa tse fapaneng tse sa tloaelehang tse bakiloeng nakong ea ts’ebetso ea tlhahiso le tsona li hlahisa litšenyehelo tse ncha. Ho se sebetse hantle ha betri ea polymer ka boeona le eona e tlisa ho fetoha ha moralo, ‘me hangata e hlophisoa bocha hore bareki ba hlahise phapang ea 1mm.
