Imwe yesimbi yakakosha pasi pano imhangura. Pasina iyo, hatikwanisi kuita zvinhu zvatinotora sezvisingakoshi zvakadai sekubatidza maraiti kana kuona TV. Mhangura ndiyo tsinga dzinoita kuti makombiyuta ashande. Hatingakwanise kufamba nemota dzisina mhangura. Nharembozha dzaizomira kufa. Uye mabhatiri e-lithium-ion aisazoshanda zvachose pasina iyo.
Lithium-ion mabhatiri anoshandisa simbi dzakaita semhangura nealuminium kugadzira kuchaji yemagetsi. Imwe neimwe lithium-ion bhatiri ine graphite anode, metal oxide cathode, uye inoshandisa electrolytes inodzivirirwa neinoparadzanisa. Kuchaja bhatiri kunoita kuti lithium ions iyerere nemuma electrolytes uye iunganidze pa graphite anode pamwe chete nemaerekitironi anotumirwa kuburikidza nekubatanidza. Kubvisa bhatiri kunotumira maion kumashure kwaakauya uye kunomanikidza maerekitironi kuti apinde nepadunhu achigadzira magetsi. Bhatiri richapera kana ose e lithium ions uye maerekitironi adzokera kucathode.
Saka, ndechipi chikamu chinotamba nemhangura nemabhatiri e-lithium-ion? Graphite inosanganiswa nemhangura pakugadzira anode. Mhangura inopesana neoxidization, inova kemikari maitiro apo maerekitironi echimwe chinhu anorasika kune chimwe chinhu. Izvi zvinokonzera ngura. Oxidization inoitika kana kemikari neokisijeni zvichidyidzana nechinhu, senge simbi inosangana nemvura uye okisijeni inogadzira ngura. Mhangura haina kudzivirirwa pakuora.
Copper foilinonyanya kushandiswa mumabhatiri e-lithium-ion nekuti hapana zvirambidzo nehukuru hwayo. Iwe unogona kuva nayo kwenguva yakareba sezvaunoda uye yakatetepa sezvaunoda. Mhangura nehunhu hwayo muunganidzi ane simba aripo, asi zvakare inobvumira kukuru uye kwakaenzana kupararira kwezvino.
Kune marudzi maviri emhangura foil: yakakungurutswa uye electrolytic. Iwe uri musimboti wakaputirwa mhangura foil inoshandiswa kune ese mhizha uye magadzirirwo. Inogadzirwa kuburikidza nemaitiro ekuunza kupisa apo uchiitsikirira pasi nemapini ekukungurusa. Kugadzira electrolytic yemhangura foil ndiyo inogona kushandiswa mune tekinoroji inobatanidzwa zvakanyanya. Inotanga nekunyungudutsa mhangura yepamusoro muacid. Izvi zvinogadzira electrolyte yemhangura inogona kuwedzerwa kumhangura kuburikidza nemaitiro anonzi electrolytic plating. Mukuita uku, magetsi anoshandiswa kuwedzera electrolyte yemhangura kufoiri yemhangura mumadhiramu anotenderera ane magetsi.
Copper foil haisi isina zvikanganiso zvayo. Copper foil inogona kupeta. Kana izvozvo zvikaitika ipapo kuunganidza simba uye kupararira kunogona kukanganiswa zvikuru. Chii chimwe ndechekuti foil yemhangura inogona kukanganiswa nekunze kwekunze senge masaini emagetsi, simba remicrowave, uye kupisa kwakanyanya. Zvinhu izvi zvinogona kuderedza kana kutoparadza kukwanisa kwefoiri yemhangura kushanda zvakanaka. Alkalis nemamwe maasidhi anogona kukanganisa kushanda kwemhangura foil. Ichi ndicho chikonzero makambani akadaiCIVENSimbi dzinogadzira zvakasiyana-siyana zvemhangura foil zvigadzirwa.
Vakadzivirira foil yemhangura inorwisa kupisa uye mamwe marudzi ekuvhiringidza. Ivo vanogadzira foil yemhangura kune chaiyo zvigadzirwa senge akadhindwa edunhu mabhodhi (PCBs) uye anochinjika edunhu mabhodhi (FCBs). Nomuzvarirwo vanogadzira foil yemhangura ye lithium-ion mabhatiri.
Lithium-ion mabhatiri ari kuramba achiwedzera, kunyanya nemotokari sezvo ivo vachigadzira induction motors senge inogadzirwa naTesla. Induction mota dzine zvikamu zvishoma zvinofamba uye zvine kuita kurinani. Induction motors dzaionekwa sedzisingawanikwe dzakapihwa simba zvinodiwa izvo zvaive zvisipo panguva iyoyo. Tesla akakwanisa kuita kuti izvi zviitike nemasero ebhatiri e-lithium-ion. Sero rega rega rinoumbwa nemabhatiri e-lithium-ion, ese ane foil yemhangura.
Kudiwa kwefoiri yemhangura kwasvika pakakwirira. Musika wemhangura wefoil wakaita mari inopfuura mabhiriyoni manomwe emadhora ekuAmerica muna 2019 uye inotarisirwa kuita mari inopfuura mabhiriyoni masere emadhora ekuAmerica muna 2026. Izvi zvinokonzerwa nekuchinja muindasitiri yemotokari iyo iri kuvimbisa kushandura kubva kune injini dzinopisa mukati kuenda kumabhatiri e-lithium-ion. Nekudaro, mota haizove iyo yega indasitiri inobatwa sezvo makomputa uye mamwe magetsi anoshandisawo foil yemhangura. Izvi zvichaita chete nechokwadi kuti mutengo wefoil yemhanguraicharamba ichikwira mumakore gumi ari kuuya.
Mabhatiri eLithium-ion akatanga kupihwa patent muna 1976, uye aizotengeswa muhuwandu muna 1991. Mumakore akatevera, mabhatiri e-lithium-ion aizova akakurumbira uye aizovandudzwa zvakanyanya. Tichifunga nezvekushandisa kwavo mumotokari, zvakachengeteka kutaura kuti vachawana mamwe mashandisiro munyika inobvira inotsamira simba sezvo ivo vachichajiswa uye vachinyanya kushanda. Lithium-ion mabhatiri inguva yemberi yesimba, asi haisi chinhu pasina foil yemhangura.
