CMC papa-pākaukau

ʻO ka carboxymethyl cellulose (CMC) kahi ʻano kūikawā o ka CMC i hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa a me ka mānoanoa i ka hana ʻana o nā pā lithium-ion (LIB). ʻO nā LIBs he mau pākiki hiki ke hoʻouka hou ʻia i hoʻohana mau ʻia i nā mea uila uila, nā kaʻa uila, a me nā ʻōnaehana mālama ikehu ma muli o ko lākou kiʻekiʻe ikehu kiʻekiʻe a me ke ola pōʻai lōʻihi. He kuleana koʻikoʻi ka CMC i ke kaʻina hana electrode o LIB, ʻoi aku ka nui o ka hana ʻana o nā electrodes no ka cathode a me ka anode.

Nā hana a me nā waiwai o ka CMC-Grade Battery:

1. Hoʻopili: Hana ʻia ka CMC helu pākaukau ma ke ʻano he mea hoʻopaʻa e kōkua i ka hoʻopaʻa ʻana i nā mea electrode ikaika (e like me ka lithium cobalt oxide no nā cathodes a me ka graphite no nā anodes) a hoʻopili iā lākou i ka substrate hōʻiliʻili o kēia manawa. ). Mālama kēia i ka conductivity uila maikaʻi a me ka paʻa mechanical o ka electrode.
2. Mānoanoa Mānoanoa: Hoʻohana pū ʻia ʻo CMC ma ke ʻano he mea mānoanoa i ka hoʻokumu ʻana o ka electrode slurry. Kōkua ia i ka hoʻomalu ʻana i ka viscosity a me nā waiwai rheological o ka slurry, e ʻae ana i ka uhi like ʻana a me ka waiho ʻana o ka mea electrode ma luna o ka ʻohi o kēia manawa. Mālama kēia i ka mānoanoa electrode a me ka density, he mea koʻikoʻi no ka loaʻa ʻana o ka hana pākaukau maikaʻi loa.
3. Ionic Conductivity: Hiki ke hoʻololi kūikawā ʻia a hoʻonohonoho ʻia paha ʻo CMC e hoʻomaikaʻi i kona conductivity ionic i loko o ka electrolyte pākahiko. Hiki i kēia ke hoʻomaikaʻi i ka hana electrochemical holoʻokoʻa a me ka pono o ka pā lithium-ion.
4. Electrochemical Stability: Ua hoʻolālā ʻia ʻo CMC-grade battery e mālama i kona kūpaʻa a me ke kūpaʻa electrochemical ma luna o ke ola o ka pākaukau, ʻoiai ma lalo o nā kūlana hana koʻikoʻi e like me nā wela kiʻekiʻe a me nā kaʻa uila. Mālama kēia i ka hilinaʻi lōʻihi a me ka palekana o ka pākaukau.

Kaʻina hana:

Hoʻokumu pinepine ʻia ka CMC ma o ka hoʻololi kemika o cellulose, he polysaccharide maoli i loaʻa mai nā mea kanu. Hoʻokomo ʻia nā pūʻulu carboxymethyl (-CH2COOH) i ka iwi kuamoʻo cellulose ma o ke ʻano o nā hopena kemika, ka hopena i ka hoʻokumu ʻana i ka carboxymethyl cellulose. Hiki ke hoʻohālikelike ʻia ke kiʻekiʻe o ka carboxymethyl substitution a me ke kaumaha molekala o ka CMC e hoʻokō i nā koi kikoʻī o nā noi pākaukau lithium-ion.

Nā noi:

Hoʻohana nui ʻia ʻo CMC i ka hana ʻana i nā electrodes no nā pā lithium-ion, me nā cylindrical a me nā hoʻonohonoho ʻeke pouch. Hoʻohui ʻia ia i loko o ka hoʻoheheʻe ʻana o ka electrode slurry me nā mea ʻē aʻe e like me nā mea electrode ikaika, nā mea hoʻohui conductive, a me nā solvents. Hoʻopili ʻia ka slurry electrode ma luna o ka substrate hōʻiliʻili o kēia manawa, hoʻomaloʻo ʻia, a hui ʻia i loko o ke keena pākaukau hope loa.

Pono:

1. Hoʻomaikaʻi ʻia ka Electrode Performance: Kōkua ʻo CMC i ka pākaukau i ka hoʻoikaika ʻana i ka hana electrochemical, ka paʻa paʻa paʻa, a me ka hiki ke helu o nā pā lithium-ion ma o ka hōʻoia ʻana i ka uhi electrode like ʻole a me ka hoʻopili ikaika ʻana ma waena o nā mea hana a me nā mea hōʻiliʻili o kēia manawa.
2. Hoʻonui i ka palekana a me ka hilinaʻi: ʻO ka hoʻohana ʻana i ka CMC kiʻekiʻe kiʻekiʻe me nā waiwai i hoʻopili ʻia e kōkua i ka palekana, hilinaʻi, a me ka lōʻihi o nā pā lithium-ion, e hōʻemi ana i ka hopena o ka electrode delamination, nā pōkole pōkole, a me nā hanana holo wela.
3. Nā Hoʻohālikelike Hoʻohālikelike: Hiki ke hoʻopili ʻia nā hoʻoheheʻe ʻana i ka pākaukau CMC no ka hoʻokō ʻana i nā koi kikoʻī a me nā pahuhopu hana o nā kemika pākaukau like ʻole, nā noi, a me nā kaʻina hana.

ʻO ka hōʻuluʻulu manaʻo, ʻo ka carboxymethyl cellulose (CMC) kahi mea hana kūikawā e hana nui ana i ka hana ʻana i nā ʻeke lithium-ion kiʻekiʻe. ʻO kāna mau waiwai kūʻokoʻa ma ke ʻano he mea hoʻopaʻa a me ka mānoanoa e hāʻawi i ka kūpaʻa, ka pono, a me ka palekana o nā electrodes pākahi lithium-ion, e hiki ai i ka holomua o nā ʻenehana ikehu maʻemaʻe a me ka neʻe uila.
