Lithium-ion mabhatiri ane mabhenefiti ehukuru hukuru, hupenyu hurefu hwekutenderera, uye hapana ndangariro. Vave bhatiri rinosarudzwa kune zvigadzirwa zvemagetsi zvevatengi zvepasi rose uye bhatiri rinonyanya kushandiswa kwemotokari itsva simba.Kuwanda kwesimba uye kukurumidza kuchaja maitiro asingadzivisiki mukugadzirwa kwe lithium battery products. Kuwedzera conductive agents kune yakanaka electrode zvinhu inzira inoshanda yekuvandudza mashandiro emabhatiri e lithium.
Inogona kuwedzera zvakanyanya conductive zvimiro zveakanaka uye asina kunaka emagetsi, kuwedzera bhatiri vhoriyamu simba density, uye kuderedza kuramba. , wedzera deintercalation uye kuisa kukurumidza kwe lithium ions, zvakanyanya kunatsiridza mutengo webhatiri uye kuburitsa kushanda, uye kuvandudza kukurumidza kuchaja kuita kwemotokari dzemagetsi.Iyo inonzi graphene bhatiri haina kugadzirwa negraphene zvinhu mubhatiri rese, asi inoshandisa graphene. zvinhu muma electrode ebhatiri.

Muchirevo, graphene electrodes inogona kuva nekaviri yehuwandu hwe graphite. Uyezve, kana graphene nekabhoni dema zvakasanganiswa uye zvichiwedzerwa se conductive additives kune lithiamu mabhatiri, kupikisa kwemukati kwebheteri kunogona kuderedzwa zvinobudirira, uye chiyero chebhatiri. kuburitsa kuita uye hupenyu hwekutenderera hunogona kuvandudzwa.
Uyezve, kukotama kwebhatiri hakuna chekuita pakuchaja uye kuburitsa kuita, saka ma electrode anogadzirwa negraphite. Mushure mezvishandiso zvegraphene, bhatiri rine chaji yepamusoro uye mwero wekubuda, ndosaka mabhatiri egraphene achikurumidza kuchaja.
