Muindasitiri yemabhatiri e lithium, semudziyo mukuru wekugadzira, kugadzikana kwepuratifomu yekufambisa yemuchina wekuputira kunoita basa guru mukugadzirwa kwemabhatiri e lithium. Mumakore achangopfuura, makambani mazhinji ekugadzira mabhatiri e lithium akaona kuti pakuvandudza michina yavo, mushure mekutsiva hwaro hwesimbi yechinyakare nehwaro hwe granite, kugadzikana kwepuratifomu yekufambisa kwasvika padanho repamusoro. Zvichienderana nemiedzo chaiyo, chiyero chekuvandudza kugadzikana chasvika pa200%. Tevere, tichaongorora zvikonzero zviri shure kwacho.
Kusiyana kwezvinhu zvechisikigo ndiko kwakaita kuti pave nekugadzikana
Kugadzikana kwekupisa: Granite ine zvakanakira zvakakosha
Munguva yekushanda kwemuchina we lithium battery coating, zvinhu zvakaita sekumhanya kwemota uye kupisa kunokonzerwa nekukweshana zvinogona kukonzera kuchinja-chinja kwekushisa kwakakomberedza michina. Kuwanda kwekuwedzera kwekushisa kwesimbi yakakandwa kunenge 12×10⁻⁶/℃, uye saizi yayo inochinja zvakanyanya kana tembiricha ikasiyana. Semuenzaniso, kana tembiricha ikakwira ne10℃, base yesimbi yakakandwa ine urefu hwemita imwe inogona kureba ne120μm. Kuwanda kwekuwedzera kwekupisa kwegranite kwakaderera zvakanyanya, chete (4-8) ×10⁻⁶/℃. Pasi pemamiriro akafanana, kureba kwebase yegranite ine urefu hwemita imwe kunongova 40-80μm chete. Kuchinja kudiki kwekupisa kunoreva kuti munzvimbo yekugadzira ine shanduko dzekupisa dzinowanzoitika, base yegranite inogona kuchengetedza zviri nani kururama kwekutanga kwepuratifomu inofamba uye kuve nechokwadi chekugadzikana kwemaitiro ekuputira.
Kuomarara uye kushanda kwekudzikisa: Granite iri nani
Kusimba kwechinhu kunotarisa kugona kwechigadzirwa kuramba kushanduka, nepo kushanda kwekudzikisa kunoenderana nekushanda zvakanaka kwesimba rekudzikisa. Kunyangwe simbi yakakandwa ine kuomarara, ine chimiro chegirafiti chakapfava mukati. Pasi pechiito chenguva refu chekutsinhana kushushikana kunokonzerwa nekushanda kwemidziyo, inowanzo kuve nekumanikidzwa, zvichikonzera kushanduka uye kukanganisa kugadzikana kwepuratifomu. Kusiyana neizvi, granite yakaoma muchimiro, ine chimiro chemukati chakakora uye kuomarara kwakanaka. Chimiro chayo chakasiyana chemineral chinoipa simba rakanaka rekudzikisa, zvichiita kuti ikwanise kushandura nekukurumidza simba rekudzikisa kuita simba rekupisa kuti ripararire. Zvidzidzo zvakaratidza kuti munzvimbo inodedera ye100Hz, granite inogona kuderedza kudengenyeka mukati memasekonzi 0.12, nepo simbi yakakandwa ichida masekondi 0.9. Kana muchina wekudzikisa bhatiri re lithium uchishanda nekukurumidza, granite base inogona kuderedza zvakanyanya kupindira kwekudzikisa pamusoro wekudzikisa, ichivimbisa ukobvu hwekudzikisa hwakaenzana uye hwakafanana.
Rutsigiro rwehuwandu hwedata kuti pave nekugadzikana kwakasimba
Kuyedzwa kwekudengenyeka: Kusiyana kwehukuru hweamplitude kwakasiyana
Masangano ehunyanzvi akaita bvunzo dzekudengenyeka pamapuratifomu ekufamba kwemashini e lithium battery coating ane mabhesi esimbi akakandwa uye mabhesi egranite zvakateerana. Kana muchina wekuvhara uchishanda zvakanaka uye kumhanya kwacho kwakaiswa pa100m/min, sensor yekudengenyeka yakanyatsonaka inoshandiswa kuyera amplitude yezvikamu zvakakosha zvepuratifomu. Mhedzisiro yacho inoratidza kuti amplitude yepuratifomu inofamba yesimbi yakakandwa iri 20μm munzira yeX-axis uye 18μm munzira yeY-axis. Mushure mekutsiviwa negranite base, amplitude yeX-axis yakaderera kusvika pa6μm uye yeY-axis yakaderera kusvika pa5μm. Kubva padata re amplitude, zvinogona kuonekwa kuti granite base yakaderedza amplitude yepuratifomu inofamba munzira mbiri huru neinenge 70%, zvichideredza zvakanyanya kukanganiswa kwekudengenyeka pakururama kwe coating uye zvichipa humbowo hwakasimba hwekuvandudza kugadzikana.
Kugadzirisa kururama kwenguva refu: Kukura zvishoma nezvishoma kwekukanganisa
Munguva yebvunzo yekushanda kwemaawa masere inoenderera mberi yekuvhara, kunyatsorongeka kwepuratifomu kwaiongororwa panguva chaiyo. Pakushandisa base yesimbi yakakandwa, kukanganisa kwekuisa puratifomu kunowedzera zvishoma nezvishoma nekufamba kwenguva. Mushure memaawa masere, kukanganisa kwekuisa cumulative kwemaXY axes kunosvika ±30μm. Kukanganisa kwekuisa puratifomu yekufamba negranite base mushure memaawa masere kunongova ±10μm chete. Izvi zvinoratidza kuti panguva yekugadzira kwenguva refu, base yegranite inogona kuchengetedza kururama kwepuratifomu zviri nani, kudzivirira kutsauka kwenzvimbo yekuvhara kunokonzerwa nekudonha kwekururama, uye kusimbisa zvakare kugadzikana kwayo.
Kugadzikana kwekusimbisa mhedzisiro chaiyo yekugadzira kwavandudzwa
Pamuchina chaiwo wekugadzira mabhatiri e lithium, mabhesi esimbi akaumbwa emamwe machina ekuputira akagadziridzwa kuita mabhesi e granite. Kuvandudzwa kusati kwaitwa, mwero wekukanganisa wechigadzirwa waive wakakwira kusvika 15%, nezvikanganiso zvikuru zvinosanganisira ukobvu hwekuputira husina kuenzana uye kutsauka kwekuputira pamucheto wepepa re electrode. Mushure mekuvandudzwa, mwero wekukanganisa wechigadzirwa wakaderera zvakanyanya kusvika 5%. Mushure mekuongorora, imhaka yekuti granite base inowedzera kugadzikana kwepuratifomu inofamba ndiyo nzira yekuputira inova yakanyatsojeka uye inodzorwa, zvichideredza zvikanganiso zvechigadzirwa zvinokonzerwa nemapuratifomu asina kugadzikana. Izvi zvinoratidza zvizere mhedzisiro yakanaka yegranite base pamhando yekugadzira mumashini ekuputira mabhatiri e lithium.
Mukupedzisa, kungave kubva mukuongorora kwedzidziso yehunhu hwezvinhu, data rekuyedza huwandu chaihwo, kana mhinduro yemhedzisiro pamutsetse wekugadzira, zvinoratidza zvakajeka kuti kuvandudzwa kwekugadzikana kwepuratifomu yekufamba kwemuchina we lithium battery coating uchishandisa granite base kana tichienzanisa ne cast iron base kunogona kusvika 200%. Kune makambani ekugadzira lithium battery anotsvaga mhando yepamusoro uye kugona kwepamusoro, granite base pasina mubvunzo isarudzo yakakosha yekuvandudza mashandiro emuchina we coating.
