Li-ion mabhatiri anenge ari kwese kwese.Iwo anoshandiswa mukushandisa kubva kunharembozha uye malaptop kune dzakasanganiswa uye dzemagetsi mota.Mabhatiri eLithium-ion ari kuwedzerawo mukurumbira mumashandisirwo makuru seUninterruptible Power Supplies (UPSs) uye akamira Battery Energy Storage Systems (BESSs).
Bhatiri mudziyo une rimwe kana akawanda maseru eelectrochemical ane majokoni ekunze ekugonesa midziyo yemagetsi.Kana bhatiri richipa simba remagetsi, nzvimbo yaro yakanaka ndiyo cathode, uye iyo negative terminal ndiyo anode.The terminal marked negative ndiko kunobva maerekitironi ayo achayerera nepanze remagetsi redunhu kuenda kune positive terminal.
Kana bhatiri rakabatanidzwa kune kunze kwemagetsi mutoro, redox (kuderedza-oxidation) reaction inoshandura-high-energy reactants kune zvigadzirwa zvepasi-simba, uye mutsauko wekusununguka-simba unoendeswa kudunhu rekunze semagetsi emagetsi.Kubva kare izwi rekuti "bhatiri" rinonyanya kureva mudziyo unoumbwa nemasero akawanda;zvisinei, kushandiswa kwakashanduka kuti kusanganise midziyo inoumbwa nesero rimwe chete.
Lithium-ion bhatiri inoshanda sei?
Mabhatiri mazhinji eLi-ion anogovanisa dhizaini yakafanana nesimbi oxide positive electrode (cathode) yakavharwa pamuunganidzi wearuminiyamu, negative electrode (anode) yakagadzirwa kubva kucarbon/graphite yakavharwa pamuunganidzi wemhangura, chinoparadzanisa uye electrolyte yakagadzirwa lithium munyu mune organic solvent.
Kunyange zvazvo bhatiri richibuda uye richipa magetsi emagetsi, iyo electrolyte inotakura zvakanaka chaja lithium ions kubva kune anode kuenda kune cathode uye vice versa kuburikidza neseparator.Kufamba kweiyo lithium ion kunogadzira maerekitironi emahara muanode iyo inogadzira mutero kune yakanaka ikozvino muunganidzi.Ikozvino magetsi anobva ayerera kubva kumuunganidzi wezvino kuburikidza nemudziyo uri kufambiswa (serura, komputa, nezvimwewo) kuenda kune yakaipa ikozvino muunganidzi.Iyo inoparadzanisa inovhara kufamba kwemaerekitironi mukati mebhatiri.
Panguva yekuchaja, magetsi ekunze emagetsi sosi (yekuchaja dunhu) anoshandisa over-voltage (yakakwirira voltage kupfuura inogadzirwa nebhatiri, yepolarity yakafanana), ichimanikidza ikozvino kuchaja kuyerera mukati mebhatiri kubva kune yakanaka kuenda kune yakaipa electrode, kureva kune reverse direction yezvinobuda zvinobuda mumamiriro akajairika.Iyo lithium ion inobva yatama kubva kune yakanaka kuenda kune yakaipa electrode, iyo inova yakaiswa mu porous electrode zvinhu nenzira inozivikanwa se inter-calation.
