Kugirango ugere kuri super yihuta cyane, bateri, umutwara wingenzi mubikorwa byo kwishyuza, nayo igomba guhinduka.Kwishyuza byihuse bya batiri ahanini biterwa no kwishyuza no gusohora kwa bateri.Hariho impamvu eshatu zingenzi zitera ingaruka zo gukuza umuriro: ibikoresho bya electrode, imbaraga zo kwishyuza ikirundo nubushyuhe bwa batiri.Ku mishinga ya batiri, imbaraga zo kwishyuza ibirundo ni ikintu gifatika, kandi ibikoresho bya electrode no kugenzura ubushyuhe niho inganda za batiri zishobora guhindura.
Mumashanyarazi ya batiri, ubushobozi bwumuriro bwihuse bwa bateri biterwa nubushobozi bwinshi nkubushobozi bwa lithium bwihuse bwo kwinjiza electrode mbi, ubwikorezi bwa electrolyte, hamwe nubushobozi bwo gucunga ubushyuhe bwa sisitemu ya bateri.
Iyo kwishyuza byihuse, lithium ion igomba kwihuta kandi igahita yinjizwa muri electrode mbi.Ibi bivuguruza ubushobozi bwa electrode mbi yo kwakira vuba lithium ion.Niba electrode mbi idafite ubushobozi bwihuse bwo gushyiramo lithium, imvura ya lithium cyangwa na lithium dendrite bizabaho, bizatuma habaho kwiyongera bidasubirwaho kwubushobozi bwa bateri no kugabanya igihe cya serivisi.Byongeye kandi, electrolyte isaba kandi umuvuduko mwinshi kandi isaba kurwanya ubushyuhe bwinshi, flame retardant na anti-charge.Ku rundi ruhande, amashanyarazi yihuta cyane azazana ubwiyongere bukabije bwubushyuhe, kandi gucunga ubushyuhe bwamapaki ya batiri yumuriro mwinshi ni ngombwa.
Muri rusange, muburyo bwiza bwo gupakira bateri, kurinda ikwirakwizwa ryumuriro birashobora gukorwa mugukoresha ibikoresho byogukoresha ubushyuhe hamwe nubushyuhe bwo hejuru bwumuriro, nkibikoresho bya ceramic insulasique na mika.Ariko, usibye kurinda ubushyuhe bwumuriro, gukemura ibibazo byo gukingira ubushyuhe nabyo ni ngombwa.Mu imurikagurisha ry’imodoka rya Shanghai, inganda zitandukanye zikoresha amashanyarazi nazo "zerekanye ubuhanga bwazo" zijyanye no guhanga ibintu hamwe no gucunga neza ubushyuhe.
Mbere, tekinoroji ya ultra-yihuta yo kwishyiriraho mugihe cya Ningde yakwirakwije imiyoboro ya elegitoronike, impeta ya ion yihuta, isotropic graphite, superrolducting electrolytes, diaphragms ya pore ndende, electrode-gradient nyinshi, amatwi menshi, anode ishobora gukurikirana, nibindi.
Tekinoroji ya Anotropique ituma lithium ion yinjizwa mumashusho ya grafite ya dogere 360 kugirango yongere umuvuduko mwinshi.Ikurikiranwa rya Anode rishobora guhindura amashanyarazi mugihe gikwiye, kugirango bateri ishobore kongera ubushobozi bwayo bwo kwishyuza murwego rwumutekano hatabayeho reaction ya lithium, kandi ikagera kuburinganire hagati yumuvuduko ukabije wumuriro numutekano.Bateri ya ternary Kirin ifata sisitemu yo hejuru ya nikel cathode + silicon ishingiye kuri sisitemu ya electrode mbi, hamwe nubucucike bwingufu zigera kuri 255Wh / kg, bifasha gutangira iminota 5 byihuse kandi 10min ikishyuza 80%.Nyamara, mugihe cyo kwishyuza no gusohora, kwaguka kwa silikoni birashobora kugera kuri 400%, kandi ibikoresho bikora biroroshye gutandukana na plaque ya polar, bigatuma imbaraga ziyongera vuba kandi bigakora SEI itajegajega.Kubwibyo, ibikoresho bitwara mugihe cya Ningde bifata karubone imwe ya karubone imwe ya diametre ya 1.5 ~ 2 ya nanotube, ihuza cyane na anode ya silicon kandi ifite umuyoboro wuzuye.Nubwo ibice bya silicon anode byaguka mubunini hanyuma bigatangira kugaragara, birashobora gukomeza guhuza neza binyuze muri karubone imwe ya karubone.Byongeye kandi, electrolyte ya batiri ya Kirin ifata LiFSI kandi ikoresha inyongera ya FEC kugirango ikore fluoride ya lithium kuri electrode mbi.Iion radiyo ni nto, irashobora gusana ibice mugihe.Kubijyanye no gucunga amashyuza, Bateri ya Kirin ihuza sisitemu yo gukonjesha amazi hamwe nubushyuhe bwo kubika ubushyuhe muri sandwich ikora ibintu byinshi hagati ya selile.Ugereranije na plaque gakondo ikonjesha isahani yashyizwe hejuru yakagari, ahantu ho kohereza ubushyuhe bwikubye kane.Turashimira ahantu hanini ho gukonjesha, ubushobozi bwo kugenzura ubushyuhe bwakagari bwiyongereyeho 50%.Isahani ihagaritse gukonjesha irema horizontal igereranije umwanya wo kwigunga.Hariho impapuro zo kwagura indishyi + adiabatic airgel hagati ya selile ndende, itanga neza ubushyuhe kugirango igere kuri "zero yumuriro wa zeru".
