01 Batteri ya lithium-air na batiri ya lithium-sulfure ni iki?
Batiri Bateri
Batiri ya lithium-air ikoresha ogisijene nka reaction ya electrode nziza na lithium yicyuma nka electrode mbi.Ifite ingufu zingana cyane (3500wh / kg), kandi ubwinshi bwingufu zayo zishobora kugera kuri 500-1000wh / kg, ibyo bikaba birenze cyane sisitemu ya batiri isanzwe ya lithium-ion.Batteri ya Litiyumu-mwuka igizwe na electrode nziza, electrolytite na electrode mbi.Muri sisitemu ya bateri idafite amazi, ogisijeni yuzuye ikoreshwa nka gaze ya reaction, bityo bateri ya lithium-air nayo ishobora kwitwa bateri ya lithium-ogisijeni.
Mu 1996, Aburahamu n'abandi.guteranya neza bateri ya mbere idafite amazi ya lithium-air muri laboratoire.Hanyuma abashakashatsi batangiye kwita kumyitwarire ya electrochemic imbere nuburyo bwa bateri ya lithium-air idafite amazi;muri 2002, Soma n'abandi.yasanze imikorere ya electrochemic ya batteri ya lithium-air iterwa na electrolyte solvent hamwe nibikoresho bya cathode yo mu kirere;muri 2006, Ogasawara n'abandi.yakoresheje Mass spectrometer, byagaragaye ku nshuro ya mbere ko Li2O2 yahinduwe okiside ndetse na ogisijeni irekurwa mu gihe cyo kwishyuza, byemeza ko amashanyarazi ya Li2O2 yahindutse.Kubwibyo, bateri ya lithium-air yitabiriwe cyane niterambere ryihuse.
Batiri Batiri ya Litiyumu-sulfure
Batiri ya Litiyumu-sulfure ni sisitemu ya kabiri ya batiri ishingiye ku myitwarire idasubirwaho y’ubushobozi bwihariye bwa sulfure (1675mAh / g) hamwe n’icyuma cya lithium (3860mAh / g), hamwe n’umuvuduko w’amashanyarazi ugereranyije ugera kuri 2.15V.Ingufu zayo zingirakamaro zishobora kugera kuri 2600wh / kg.Ibikoresho byayo bibisi bifite ibyiza byo kugiciro gito no kubungabunga ibidukikije, bityo bifite iterambere ryinshi.Ivumburwa rya batiri ya lithium-sulfure irashobora guhera mu myaka ya za 1960, igihe Herbert na Ulam basabye ipatanti.Porotipire yiyi batiri ya lithium-sulfure yakoresheje lithium cyangwa lithium alloy nkibikoresho bibi bya electrode, sulfure nkibikoresho byiza bya electrode kandi bigizwe na amine yuzuye alifatique.ya electrolyte.Nyuma yimyaka mike, bateri ya lithium-sulfure yatejwe imbere mugutangiza imashanyarazi nka PC, DMSO, na DMF, hanyuma haboneka bateri 2.35-2.5V.Mu mpera z'imyaka ya za 1980, ethers byagaragaye ko ari ingirakamaro muri bateri ya lithium-sulfure.Mu bushakashatsi bwakurikiyeho, kuvumbura electrolytite ishingiye kuri ether, gukoresha LiNO3 nk'inyongeramusaruro ya electrolyte, hamwe n'icyifuzo cya karubone / sulfure ikomatanya electrode nziza byafunguye ubushakashatsi kuri bateri ya lithium-sulfure.
02 Ihame ryakazi rya batiri ya lithium-air na batiri ya lithium-sulfure
Batiri Bateri
Ukurikije leta zitandukanye zikoreshwa na electrolyte ikoreshwa, bateri ya lithium-air irashobora kugabanywamo sisitemu y'amazi, sisitemu ngenga, sisitemu ya Hybride y’amazi, hamwe na bateri zose za lithium-air.Muri byo, kubera ubushobozi buke bwihariye bwa bateri ya lithium-air ukoresheje electrolytite ishingiye ku mazi, ingorane zo kurinda ibyuma bya lithium, hamwe no kudasubira inyuma kwa sisitemu, bateri ya lithium-air idafite amazi hamwe na lithium-air-ikomeye-ikomeye bateri zikoreshwa cyane muri iki gihe.Ubushakashatsi.Batteri idafite amazi ya lithium-air yatanzwe bwa mbere na Abraham na Z.Jiang mu 1996. Ikigereranyo cyo gusohora ibintu cyerekanwe ku gishushanyo cya 1. Uburyo bwo kwishyuza buratandukanye.Electrolyte ikoresha cyane cyane electrolyte organic cyangwa electrolyte ikomeye, kandi ibicuruzwa bisohora cyane cyane Li2O2, ibicuruzwa ntibishobora gushonga muri electrolyte, kandi byoroshye kwirundanyiriza kuri electrode nziza yumwuka, bigira ingaruka kubushobozi bwo gusohora bateri ya lithium-air.
Batteri ya Litiyumu-air ifite ibyiza byo gukomera kwinshi cyane, kubungabunga ibidukikije, ndetse nigiciro gito, ariko ubushakashatsi bwabo buracyari mu ntangiriro, kandi haracyari ibibazo byinshi bigomba gukemurwa, nka catalizike yo kugabanya umwuka wa ogisijeni, umwuka wa ogisijeni na hydrophobicity ya electrode yo mu kirere, hamwe no gukuraho electrode yo mu kirere n'ibindi.
Batiri Batiri ya Litiyumu-sulfure
Batteri ya Litiyumu-sulfuru ikoresha cyane cyane ibice bya sulfure cyangwa sulferi nkibintu byiza bya electrode nziza ya bateri, kandi lithium metallic ikoreshwa cyane cyane kuri electrode mbi.Mugihe cyo gusohora, lithium yicyuma iherereye kuri electrode mbi iba oxyde kugirango ibuze electron kandi ikabyara ioni;noneho electron zihererekanwa kuri electrode nziza binyuze mumuzunguruko wo hanze, hanyuma ion ya lithium yakozwe nayo yimurirwa kuri electrode nziza binyuze muri electrolyte kugirango ikore hamwe na sulfure kugirango ikore polysulfide.Litiyumu (LiPSs), hanyuma ikongera ikabyara kubyara lithium sulfide kugirango irangize inzira yo gusohora.Mugihe cyo kwishyuza, ioni ya lithium muri LiPSs igaruka kuri electrode itari nziza ikoresheje electrolyte, mugihe electron zisubira kuri electrode mbi zinyuze mumuzunguruko wo hanze zikora ibyuma bya lithium hamwe na ion ya lithium, naho LiPS igabanuka kuri sulferi kuri electrode nziza kugirango irangize. uburyo bwo kwishyuza.
Uburyo bwo gusohora bateri ya lithium-sulfure ahanini ni intambwe nyinshi, electron nyinshi, ibyuma byinshi bigizwe na electrochemical reaction kuri cathode ya sulfure, na LiPSs zifite uburebure butandukanye bwumunyururu zihinduka hagati yazo mugihe cyo kwishyuza-gusohora.Mugihe cyo gusohora, reaction ishobora kugaragara kuri electrode nziza irerekanwa mumashusho 2, naho reaction kuri electrode mbi irerekanwa mumashusho 3.
Ibyiza bya bateri ya lithium-sulfure iragaragara cyane, nkubushobozi buhanitse cyane;nta ogisijeni iri mu bikoresho, kandi reaction ya ogisijeni ntishobora kubaho, bityo umutekano ukaba mwiza;umutungo wa sulferi ni mwinshi kandi sulfure yibanze ihendutse;yangiza ibidukikije kandi ifite uburozi buke.Nyamara, bateri ya lithium-sulfure nayo ifite ibibazo bitoroshye, nkingaruka za lithium polysulfide;gukingira sulfure yibanze n'ibicuruzwa byayo bisohora;ikibazo cyimpinduka nini;SEI idahindagurika nibibazo byumutekano biterwa na lithium anode;kwiyitirira ibintu, nibindi
Nkibisekuru bishya bya sisitemu ya kabiri ya batiri, bateri ya lithium-air na batiri ya lithium-sulfure bifite agaciro gakomeye kerekana ubushobozi bwihariye, kandi byashimishije cyane abashakashatsi nisoko rya kabiri rya batiri.Kugeza ubu, bateri zombi ziracyafite ibibazo byinshi bya siyansi na tekiniki.Bari mubyiciro byubushakashatsi bwambere bwo guteza imbere bateri.Usibye ubushobozi bwihariye hamwe nubutunzi bwibikoresho bya cathode ya cathode ikeneye kurushaho kunozwa, ibibazo byingenzi nkumutekano wa batiri nabyo bigomba gukemurwa byihutirwa.Mugihe kizaza, ubu bwoko bubiri bwa bateri buracyakeneye kunonosorwa muburyo bwa tekinike kugirango bakureho inenge kugirango bafungure ibyifuzo byinshi.
