ʻO ke kaʻina hana kuʻuna o ka hana ʻana i ka paʻi kelepona pākaukau lithium

Power batterie Lithium battery cell slurry stirring ʻo ia ka hui ʻana a me ka hoʻopuehu ʻana i ke kaʻina hana holoʻokoʻa o nā pā lithium-ion, a he degere ka hopena i ka maikaʻi o ka huahana ma mua o 30%, a ʻo ia ka loulou nui loa i ke kaʻina hana holoʻokoʻa.kaa electr batteri a i ole kaa electr batteri a i ole kaa electr batteri.

I ka hana ʻana i nā electrodes no nā pā lithium-ion, ʻo ka slurry electrode maikaʻi i haku ʻia me ka binder, conductive agent, a me nā mea electrode maikaʻi;ʻO ka slurry electrode maikaʻi ʻole i haku ʻia me ka binder, graphite carbon pauka, a me nā mea ʻē aʻe. Hoʻopili ʻia ke kaʻina hana me nā loli i ka mahana, viscosity, a me ke kaiapuni.I ka slurry maikaʻi a me ka maikaʻi ʻole, pili pono ka dispersibility a me ka like o ka mea hana granular i ka neʻe ʻana o nā ion lithium ma waena o nā pou ʻelua o ka pākaukau, no laila ka hui ʻana a me ka hoʻopuehu ʻana o ka slurry o kēlā me kēia ʻāpana pole i ka hana ʻana o ka lithium ion. He mea koʻikoʻi loa nā pākaukau , ʻO ka maikaʻi o ka dispersion o ka slurry e pili pono i ka maikaʻi o ka hana pākaukau lithium-ion a me ka hana o kāna mau huahana.

Lawe ʻia ka dispersion ultra-fine i ka hana kuʻuna.ʻO kēia no ka mea: ma o ka hui kuʻuna a me ka hoʻoulu ʻana, ʻo nā pūʻulu pauda nui wale nō i loko o ka hoʻonā hiki ke wāwahi a puʻunaue like ʻia;eia naʻe, mālama ʻia ke ʻano o ka pauda ma ke ʻano o nā puʻupuʻu pauda maikaʻi.I ka hoʻonā, hoʻokō wale ʻia nā koi hoʻoili o ka dispersion macroscopic.ʻO ka slurry ma hope o ka hoʻoulu ʻana a me ka hoʻopuehu ʻana, ma lalo o ka ikaika ʻoki mechanical ikaika o ka ultrafine dispersion a me nā mea hana homogenization, hiki ke wāwahi hou a homogenize i ka pauka maikaʻi a i ʻole nā ​​​​mea paʻa paʻa agglomerates i loko o ka hopena e loaʻa ai kahi paʻa maikaʻi. ka hoʻonā e hoʻokō i ka hopena o ka microscopic ultrafine dispersion a homogenization, hiki ke hoʻomaikaʻi nui i ka hana holoʻokoʻa o ka slurry.
