Imwe yesimbi dzinokosha pasi rose imhangura. Pasina iyo, hatigoni kuita zvinhu zvatinotora sezviri nyore zvakaita sekubatidza mwenje kana kuona TV. Mhangura ndiyo mitsipa inoita kuti makombiyuta ashande. Hatingakwanise kufamba nemota dzisina mhangura. Kutaurirana kwaizomira kushanda. Uye mabhatiri e lithium-ion haashande zvachose pasina iyo.
Mabhatiri eLithium-ion anoshandisa simbi dzakadai semhangura nearuminiyamu kugadzira chaji yemagetsi. Bhatiri rega rega reLithium-ion rine graphite anode, metal oxide cathode, uye rinoshandisa electrolytes dzinodzivirirwa neseparator. Kuchaja bhatiri kunoita kuti lithium ions ifambe nemuma electrolytes uye iungane pa graphite anode pamwe chete nema electrons anotumirwa kuburikidza ne connection. Kubvisa plug yebhatiri kunodzosera ma ion kwaakabva uye kunomanikidza ma electrons kuti apfuure nepakati pe circuit zvichigadzira magetsi. Bhatiri rinopera kana ma lithium ions ese nema electrons adzokera ku cathode.
Saka, mhangura inoshanda sei nemabhatiri e lithium-ion? Graphite inosanganiswa ne mhangura pakugadzira anode. Mhangura haipindi mu oxidization, inova nzira yemakemikari apo maerekitironi echimwe chinhu anorasika kune chimwe chinhu. Izvi zvinokonzera ngura. Oxidization inoitika kana kemikari neokisijeni zvikabatana nechimwe chinhu, sekuti simbi inosangana nemvura uye okisijeni inogadzira ngura. Mhangura haina ngura zvachose.
Foyi yemhangurainonyanya kushandiswa mumabhatiri e lithium-ion nekuti hapana zvirambidzo pahukuru hwayo. Unogona kuva nayo chero nguva yaunoda uye yakatetepa sezvaunoda. Mhangura ine simba guru rekuunganidza magetsi, asi inobvumirawo kupararira kukuru uye kwakaenzana kwemagetsi.
Kune mhando mbiri dze copper foil: yakakungurutswa ne electrolytic. Copper foil inoshandiswa pakugadzira zvinhu zvakasiyana-siyana. Inogadzirwa kuburikidza nekuita kuti kupisa kupfuure nekudzvanya ne rolling pins. Kugadzira copper foil inoshandiswa mu electrolytic kunogona kushandiswa mu tekinoroji. Inotanga nekunyungudutsa copper yemhando yepamusoro mu acid. Izvi zvinogadzira copper electrolyte inogona kuwedzerwa ku copper kuburikidza ne process inonzi electrolytic plating. Mukuita uku, magetsi anoshandiswa kuwedzera copper electrolyte ku copper foil muma drums anotenderera ane electrically charged.
Foil yemhangura haina zvikanganiso zvayo. Foil yemhangura inogona kukotama. Kana izvozvo zvikaitika, kuunganidzwa kwesimba uye kupararira kwesimba kunogona kukanganiswa zvakanyanya. Uyezve, foil yemhangura inogona kukanganiswa nezvinhu zvekunze zvakaita semagetsi, simba re microwave, uye kupisa kwakanyanya. Zvinhu izvi zvinogona kunonoka kana kutoparadza kugona kwefoil yemhangura kushanda nemazvo. Alkalis nedzimwe acids zvinogona kukanganisa kushanda kwefoil yemhangura. Ndosaka makambani akadai seCIVENSimbi dzinogadzira mhando dzakasiyana dzezvigadzirwa zve copper foil.
Vane jira remhangura rakadzivirirwa rinorwisa kupisa nedzimwe nzira dzekukanganisa. Vanogadzira jira remhangura rezvigadzirwa zvakaita semabhodhi edunhu akadhindwa (PCBs) uye mabhodhi edunhu anochinjika (FCBs). Zviri pachena kuti vanogadzira jira remhangura remabhatiri e lithium-ion.
Mabhatiri eLithium-ion ari kuwedzera kuva akajairika, kunyanya nemotokari sezvo dzichishandisa injini dze induction dzakadai sedzinogadzirwa naTesla. Mabhatiri e induction ane zvikamu zvishoma zvinofamba uye anoshanda zviri nani. Mabhatiri e induction aionekwa seasingawanikwe tichifunga nezvezvinodiwa zvemagetsi izvo zvaisawanikwa panguva iyoyo. Tesla yakakwanisa kuita izvi nemasero avo ebhatiri reLithium-ion. Sero rega rega rinoumbwa nemabhatiri eLithium-ion, ese ane foil yemhangura.
Kudiwa kwefoil yemhangura kwasvika pakakwirira zvikuru. Musika wefoil yemhangura wakawana mari inodarika mabhiriyoni manomwe emadhora ekuAmerica muna 2019 uye unotarisirwa kuwana mari inodarika mabhiriyoni masere emadhora ekuAmerica muna 2026. Izvi zvinokonzerwa nekuchinja kuri kuitika muindasitiri yemotokari kuri kuvimbisa kuchinja kubva kumainjini ekupisa mukati kuenda kumabhatiri e lithium-ion. Zvisinei, mota hadzisi idzo dzega indasitiri dziri kukanganiswa sezvo makomputa nezvimwe zvemagetsi zvinoshandisawo foil yemhangura. Izvi zvinongovimbisa chete kuti mutengo wefoil iyi uchakwira.foil yemhanguraicharamba ichikwira mumakore gumi anotevera.
Mabhatiri eLithium-ion akatanga kupihwa patent muna 1976, uye aizogadzirwa mukutengeserana muna 1991. Mumakore akatevera, mabhatiri eLithium-ion aizonyanya kufarirwa uye aizovandudzwa zvakanyanya. Tichifunga nezvekushandiswa kwawo mumotokari, zvakachengeteka kutaura kuti achawana mamwe mashandisirwo munyika inovimba nesimba rinobvira sezvo achichajwazve uye anoshanda zviri nani. Mabhatiri eLithium-ion ndiwo ramangwana resimba, asi haasi chinhu asina foil yemhangura.
