Sehlooho se chesang: Bafuputsi ba ikemiselitse ho fokotsa kotsi ea mollo oa libeteri tsa lithium-ion

Libetri tsa lithium-ion ke theknoloji e batlang e fumaneha hohle e nang le bothata bo tebileng: ka linako tse ling li tšoara mollo.
Video ea basebetsi le bapalami ba sefofaneng sa JetBlue ba tšelang metsi ka mekotleng ea bona e fetoha mohlala oa morao-rao oa matšoenyeho a batsi ka libeteri, tseo joale li ka fumanoang hoo e batlang e le sesebelisoa se seng le se seng se hlokang matla a ho nkeha.Lilemong tse leshome tse fetileng, ho bile le keketseho ea lihlooho tse mabapi le mollo oa betri ea lithium-ion o bakoang ke libaesekele tsa motlakase, likoloi tsa motlakase le li-laptops ka lifofane tsa baeti.
Kameho e ntseng e eketseha ea sechaba e susumelitse bafuputsi lefatšeng ka bophara ho sebetsa ho ntlafatsa polokeho le bophelo bo bolelele ba libeteri tsa lithium-ion.
Boqapi ba betri bo ntse bo phatloha lilemong tsa morao tjena, 'me bafuputsi ba thehile libeteri tsa boemo bo tiileng ka ho kenya li-electrolyte tsa metsi a ka tukang ka har'a libeteri tse tloaelehileng tsa lithium-ion tse nang le lisebelisoa tse tsitsitseng tsa electrolyte tse kang li-gel tse sa cheng, likhalase tsa inorganic le li-polymer tse tiileng.
Lipatlisiso tse hatisitsoeng bekeng e fetileng koranteng ea Nature e fana ka maikutlo a mokhoa o mocha oa tšireletso ho thibela ho thehoa ha lithium "dendrites," e hlahang ha libeteri tsa lithium-ion li chesa haholo ka lebaka la ho tjhaja kapa ho senya sebopeho sa dendritic.Li-Dendrite li ka sebelisa libeteri tse khutšoane 'me tsa baka mollo o phatlohang.
"Thuto e 'ngoe le e' ngoe e re fa kholiseho e kholo ea hore re ka rarolla mathata a polokeho le mefuta e mengata ea likoloi tsa motlakase," ho boletse Chongsheng Wang, moprofesa oa boenjiniere ba lik'hemik'hale le biomolecular Univesithing ea Maryland le mongoli ea ka sehloohong oa thuto.
Tsoelo-pele ea Wang ke mohato oa bohlokoa oa ho ntlafatsa polokeho ea libeteri tsa lithium-ion, ho boletse Yuzhang Li, motlatsi oa moprofesa oa boenjiniere ba lik'hemik'hale UCLA ea neng a sa kenelle thutong.
Lee o sebetsa ka boqapi ba hae, a theha betri ea tšepe ea lithium ea moloko o latelang e ka bolokang matla ka makhetlo a 10 ho feta likarolo tsa elektrode tsa graphite ka libeteri tse tloaelehileng tsa lithium-ion.
Ha ho tluoa tabeng ea polokeho ea likoloi tsa motlakase, Lee o itse libeteri tsa lithium-ion ha li kotsi kapa ha li tloaelehe joalokaha sechaba se nahana, 'me ho utloisisa melaoana ea tšireletso ea betri ea lithium-ion ke habohlokoa.
"Likoloi tsa motlakase ka bobeli le likoloi tse tloaelehileng li na le likotsi tsa tlhaho," o boletse joalo.Empa ke nahana hore likoloi tsa motlakase li bolokehile ho feta hobane ha u lutse holim'a lilithara tsa mokelikeli o tukang.
Lee o ile a phaella ka hore ke habohlokoa ho nka mehato ea thibelo khahlanong le ho lefella chelete e ngata kapa ka mor'a kotsi ea koloi ea motlakase.
Bafuputsi ba ithutang ka mollo oa libeteri tsa lithium-ion setsing se se nang phaello sa Fire Research Foundation ba fumane hore mollo o ka har'a likoloi tsa motlakase o tšoana le mello ea likoloi tsa setso tse tsamaeang ka peterole, empa mollo oa likoloi tsa motlakase o nka nako e telele, o hloka metsi a mangata ho tima, 'me o feta. ho ka hotetsa.hape.lihora tse 'maloa ka mor'a hore lelakabe le nyamele ka lebaka la matla a setseng ka har'a betri.
Victoria Hutchison, mookameli ea ka sehloohong oa lenaneo la lipatlisiso tsa motheo, o re likoloi tsa motlakase li beha kotsi e ikhethang ho batho ba tima mollo, ba arabelang pele le bakhanni ka lebaka la libeteri tsa bona tsa lithium-ion.Empa seo ha se bolele hore batho ba lokela ho ba tšaba, a eketsa.
"Re ntse re leka ho utloisisa hore na mello ea likoloi tsa motlakase ke eng le hore na re ka e loantša joang," ho boletse Hutcheson.“Ke mokhoa oa ho ithuta.Ke khale re e-na le likoloi tsa enjene e tukang ka hare, ha ho tsejoe, empa re tlameha feela ho ithuta ho sebetsana le liketsahalo tsena hantle. ”
Matšoenyeho ka ho cha ha likoloi tsa motlakase le ona a ka nyolla litheko tsa inshorense, ho boletse Martti Simojoki, setsebi sa thibelo ea tahlehelo ho International Union of Marine Insurance.A re ho etsa inshorense ea likoloi tsa motlakase e le thepa hajoale ke e 'ngoe ea mekhoa e sa khahliseng haholo khoebong ea liinshorense, e leng se ka eketsang litšenyehelo tsa inshorense ho ba batlang ho tsamaisa makoloi a motlakase ka lebaka la kotsi e ka bang teng ea mollo.
Empa phuputso e entsoeng ke International Union of Marine Insurance, e leng sehlopha se sa etseng phaello se emelang lik’hamphani tsa inshorense, e fumane hore likoloi tsa motlakase ha li kotsi kapa li kotsi ho feta likoloi tse tloaelehileng.Ha e le hantle, ha e e-s'o tiisetsoe hore mollo oa thepa e phahameng ho tloha lebōpong la Dutch lehlabuleng lena lehlabuleng lena o bakiloe ke koloi ea motlakase, ho sa tsotellehe lihlooho tsa litaba tse bontšang hore ha ho joalo, Simojoki o itse.
O ile a re: "Ke nahana hore batho ba leqe ho ipeha kotsing."Haeba kotsi e phahame, theko e tla ba holimo.Qetellong ea letsatsi, moreki oa ho qetela oa e lefella. ”
