Loaʻa i nā pākahi ithium-ion kahi ākea o nā noi. E like me ka hoʻokaʻawale ʻana o nā wahi noi, hiki ke hoʻokaʻawale ʻia i ka pākaukau no ka mālama ʻana i ka ikehu, ka pā mana a me ka pā uila no nā mea uila uila.
- ʻO ka pākaukau no ka mālama ʻana i ka ikehu e uhi i ka mālama ʻana i ka ikehu kamaʻilio, ka mālama ʻana i ka ikehu mana, nā ʻōnaehana ikehu puʻupuʻu, etc.;
- Hoʻohana nui ʻia ka pā uila ma ke kahua o ka mana, e lawelawe ana i ka mākeke me nā kaʻa ikehu hou, nā forklifts uila, etc.;
- ʻO ka pākaukau no nā mea uila uila e uhi i ka mea kūʻai aku a me ka ʻoihana ʻoihana, e komo pū ana me ka metering akamai, palekana naʻauao, ka lawe ʻana i ka naʻauao, Internet of Things, etc.
ʻO ka pākaukau lithium-ion he ʻōnaehana paʻakikī, ka mea nui i haku ʻia me ka anode, cathode, electrolyte, separator, collector o kēia manawa, binder, conductive agent a pēlā aku, e pili ana i nā hopena me ka hopena electrochemical o ka anode a me ka cathode, lithium ion conduction a me ka uila uila, a me ka wela wela.
ʻOi aku ka lōʻihi o ke kaʻina hana o nā pā lithium, a ʻoi aku ma mua o 50 mau kaʻina hana i ka hana.
Hiki ke hoʻokaʻawale ʻia nā pākahi Lithium i nā ʻāpana cylindrical, nā pahu pahu pahu alumini square, nā ʻeke ʻeke a me nā ʻāpana blade e like me ke ʻano. Aia kekahi mau ʻokoʻa i kā lākou kaʻina hana, akā hiki ke hoʻokaʻawale ʻia ke kaʻina hana pākaukau lithium i ke kaʻina hana mua (electrode manufacturing), kaʻina waena (cell synthesis), a me ke kaʻina hope (ka hoʻokumu ʻana a me ka hoʻopili).
E hōʻike ʻia ke kaʻina hana mua o ka hana ʻana i ka pā lithium ma kēia ʻatikala.
ʻO ka pahuhopu hana o ke kaʻina hana mua e hoʻopau i ka hana ʻana o ka electrode (anode a me ka cathode). ʻO kāna kaʻina hana nui: slurrying / mixing, coating, calendering, slitting, a me ka ʻoki make.
Slurrying/Mixing
ʻO ka slurrying / hui ʻana ʻo ia ka hoʻohui ʻana i nā mea pākaukau paʻa o ka anode a me ka cathode a hoʻohui i ka solvent e hana i ka slurry. ʻO ka hui ʻana i ka slurry ka wahi hoʻomaka o ka hopena mua o ka laina, a ʻo ia ka prelude i ka hoʻopau ʻana o ka uhi ʻana, ka calendering a me nā kaʻina hana ʻē aʻe.
Hoʻokaʻawale ʻia ka slurry pākahi lithium i ka slurry electrode maikaʻi a me ka slurry electrode maikaʻi ʻole. E hoʻokomo i nā mea hana, carbon conductive, thickener, binder, additive, solvent, etc.
ʻO ka hui ʻana kiʻekiʻe ke kumu no ka hoʻokō kiʻekiʻe o ke kaʻina hana aʻe, e hoʻopili pololei a ʻole ʻole paha i ka hana palekana a me ka hana electrochemical o ka pākaukau.
Ka uhi ʻana
ʻO ka uhi ʻana ke kaʻina hana o ka uhi ʻana i nā mea hana maikaʻi a me nā mea hana maikaʻi ʻole ma luna o ka alumini a me nā foil keleawe, a me ka hui pū ʻana me nā mea hana conductive a me ka binder e hana i ka pepa electrode. Hoʻokuʻu ʻia nā mea hoʻoheheʻe ma ka hoʻomaloʻo ʻana i ka umu i hoʻopaʻa ʻia ka mea paʻa i ka substrate e hana i ka coil electrode sheet maikaʻi a maikaʻi ʻole.
Cathode a me ka uhi anode
ʻO nā mea cathode: ʻEkolu ʻano o nā mea: ʻo ka laminated structure, spinel structure a me ka olivine structure, e pili ana i nā mea ternary (a me ka lithium cobaltate), lithium manganate (LiMn2O4) a me ka lithium iron phosphate (LiFePO4).
Nā mea anode: I kēia manawa, ʻo nā mea anode i hoʻohana ʻia i ka pākaukau lithium-ion pāʻoihana ka nui o nā mea kalapona a me nā mea ʻole carbon. Ma waena o lākou, he anode graphite, ʻo ia ka mea i hoʻohana nui ʻia i kēia manawa, a me ka anode carbon disordered, carbon hard, carbon soft, etc.; ʻO nā mea kalapona ʻole e pili ana i ka anode silicon, lithium titanate (LTO) a pēlā aku.
Ma ke ʻano he loulou kumu o ke kaʻina hana mua, ʻo ka maikaʻi o ka hoʻokō ʻana o ke kaʻina hana uhi e hoʻopilikia nui i ka paʻa, palekana a me ka pōʻai ola o ka pākaukau i hoʻopau ʻia.
Kalena
Hoʻopili hou ʻia ka electrode i uhi ʻia e ka roller, no laila e pili kokoke ana ka mea hana a me ka mea ʻohi, e hoʻemi ana i ka mamao o ka neʻe ʻana o nā electrons, e hoʻohaʻahaʻa i ka mānoanoa o ka electrode, e hoʻonui i ka hiki ke hoʻouka. I ka manawa like, hiki iā ia ke hoʻohaʻahaʻa i ke kūpaʻa kūloko o ka pākaukau, hoʻonui i ka conductivity, a hoʻomaikaʻi i ka nui o ka hoʻohana ʻana o ka pākaukau i mea e hoʻonui ai i ka mana o ka pā.
ʻO ka palahalaha o ka electrode ma hope o ke kaʻina hana calender e pili pono i ka hopena o ke kaʻina hana slitting. ʻO ka like ʻole o ka mea hana o ka electrode e hoʻopili pololei ʻole i ka hana kelepona.
ʻoki ʻana
ʻO ka slitting ka ʻoki ʻana i ka longitudinal o kahi wili electrode ākea i loko o nā ʻāpana haiki o ka laula i makemake ʻia. I ka ʻoki ʻana, ʻike ka electrode i ka hana shear a wāwahi i lalo, ʻO ka palahalaha o ka lihi ma hope o ka ʻoki ʻana (ʻaʻohe burr a flexing) ʻo ia ke kī e nānā i ka hana.
ʻO ke kaʻina hana o ka hana electrode e pili ana i ka welding electrode tab, ka hoʻopili ʻana i ka pepa adhesive pale, ka uhi ʻana i ka pā electrode a me ka hoʻohana ʻana i ka laser e ʻoki i ka pā electrode no ke kaʻina hana wili. ʻO ka ʻoki ʻoki ʻana, ʻo ia ka hoʻopaʻa ʻana a me ke ʻano o ka electrode i uhi ʻia no ka hana ma hope.
Ma muli o nā koi kiʻekiʻe no ka hana palekana lithium-ion, ʻo ka pololei, ke kūpaʻa a me ka automation o nā mea hana e koi nui ʻia i ka hana hana ʻana o ka pā lithium.
Ma keʻano he alakaʻi i nā mea hana ana i ka lithium electrode, ua hoʻokumuʻo Dacheng Precision i nā huahana no ke ana electrode i ke kaʻina hana mua o ka hanaʻana i ka pākaukau lithium, e like me ka X / β-ray areal density gauge, CDM mānoanoa a me ka nui o ka ea, laser mānoanoa ana a pēlā aku.
- ʻAi ʻana o ka nui o ka nui X-Ray
Hiki ke hoʻololi ʻia i ke ana ʻana ma luna o 1600 mm laula o ka uhi, kākoʻo i ka nānā ʻana i ka ultra-high-speed, a ʻike i nā hiʻohiʻona kikoʻī e like me nā wahi lahilahi, nā ʻōpala, a me nā ʻaoʻao keramika. Hiki ke kōkua me ka pani pani pani.
- X/β-ray ana hoʻopaʻa haʻahaʻa
Hoʻohana ʻia ia i loko o ke kaʻina hana hoʻoheheʻe electrode a me ke kaʻina hana separator ceramic coating e hana i ka hoʻāʻo ʻana ma ka pūnaewele o ka ʻāpana ākea o ka mea i ana ʻia.
- ʻO ka mānoanoa CDM a me ka ʻāpana ʻāpana
Hiki ke hoʻopili ʻia i ke kaʻina hana: ʻike pūnaewele o nā hiʻohiʻona kikoʻī o nā electrodes, e like me ka hala ʻole o ka uhi ʻana, ka nele o ka waiwai, nā ʻōpala, nā ʻāpana mānoanoa o nā wahi thinning, AT9 mānoanoa ʻike, etc.;
- Pūnaehana ana hoʻopaʻa ʻana like ʻole-nui
Hoʻohana ʻia ia no ka hoʻopaʻa ʻana i ka cathode a me ka anode o nā pā lithium. Hoʻohana ia i nā kiʻi scanning lehulehu e hana i nā ana hoʻopaʻa like ʻana ma nā electrodes. Hiki ke nānā i ke kiʻi ʻoniʻoni maʻemaʻe, ka nui o ka uhi ʻana, a me ka electrode.
- Ana mānoanoa laser
Hoʻohana ʻia ia e ʻike i ka electrode i ke kaʻina hana uhi a i ʻole ke kaʻina calendering o nā pā lithium.
- Pahemo laina mānoanoa & ana ana ana
Hoʻohana ʻia ia e ʻike i ka mānoanoa a me ka nui o nā electrodes i ke kaʻina hana uhi a i ʻole ke kaʻina calendering o nā pā lithium, e hoʻomaikaʻi ai i ka pono a me ke kūlike.
