Mea Maka No nā Anodes Graphite Artificial

1. Huahana Hua

ʻO ka mea maka no nā mea ʻano graphite artificial he mea pauda hana i hoʻomākaukau ʻia e nā kaʻina hana pololei e like me ka-carbonization, ka ʻohi ʻana, ka hoʻomaʻemaʻe, a me ka hoʻomaʻemaʻe ʻana, me ka -coke needle maʻemaʻe kiʻekiʻe, coke petroleum, a i ʻole ka lanahu -coke kumu kumu. He mea nui ia no ka hana ʻana i nā electrodes kino graphite artificial no nā pā lithium. Aia kona waiwai nui ma ka ho'olako 'ana i nā substrate ki'eki'e -no ka hana graphitization ma hope o ka ho'oponopono pololei 'ana i ka haku mele 'ana a me ke kino, e hā'awi ana i nā electrodes kino graphite artificial me ka hana maika'i loa, ka pa'a paikikala, a me ka ho'okō pono 'ana, e ho'okō ana i nā koi ko'iko'i o nā pākahi lithium no "ka mana ki'eki'e, ke ola lō'ihi, a me ka palekana ki'eki'e".

3. Core Hiʻona o ka Huahana

(1) Loaʻa ʻia ke kalapona kiʻekiʻe a me nā mea haumia haʻahaʻa

ʻOi aku ka nui o ka maʻiʻo kalapona paʻa ma mua a i ʻole like me 98.5% (nā kikoʻī kikoʻī -kiʻekiʻe ma mua o 99.5%), maʻiʻo lehu I lalo a i ʻole like me 0.3% (ka huina o nā mea haumia metala e like me Fe, Ni, Cu Liʻiliʻi a i ʻole like me 50ppm), maʻiʻo sulfur i emi a i ʻole 1% like. 0.2%; Hiki i ke ʻano haumia haʻahaʻa ke pale aku i nā hopena ʻaoʻao i ka wā o ke kaʻa uila, hoʻemi i ka decomposition electrolyte, a hōʻoia i ka paʻa o ka interface electrode maikaʻi ʻole.

(2) Hoʻonui ʻia ʻo Particle Morphology a me ka mahele ʻāpana ʻāpana

No ka Raw Material for Artificial Graphite Anodes, he spherical a ʻano like ʻole ke ʻano o nā ʻāpana, me ka ʻili maʻemaʻe a ʻaʻohe ʻaoʻao ʻoi (e pale aku i ka ʻoki ʻana i ka substrate i ka wā e uhi ai i ka electrode); ʻo kona puʻunaue ʻana i ka nui o nā ʻāpana (D50=10-50μm, Span=0.8-1.2), a hiki ke hoʻopilikino ʻia e like me nā koi mānoanoa o ka pā electrode maikaʻi ʻole. He kūpono ia no nā kaʻina hana me nā density compaction like ʻole (1.6-1.8g/cm³) e hoʻomaikaʻi i ka kūlike o ka pā electrode.

(3) ʻO ka hana kiʻi kiʻi maikaʻi loa

Loaʻa ka mana nui no ka hoʻomaikaʻi ʻana i ka degere graphitization. Ma hope o ka graphitization kiʻekiʻe -mahana ma 2800-3000 degere, hiki i ka degere graphitization ke piʻi ma luna o 90%, a ʻo ka lattice mau (c0) ʻoi aku ka liʻiliʻi a i ʻole like me 0.3356nm; I ka wā o ke kaʻina hana graphitization, paʻa mau ka nui o ka emi ʻana o ka nui (emi a like paha me 5%), hiki ke hōʻemi i ka pilikia o ka haki ʻana i nā huahana electrode maikaʻi ʻole a hoʻemi i nā poho hana.

(4) Hiki ke hoʻololi i ke kaʻina hana maikaʻi

He maikaʻi loa ka kahe ʻana o ka pauka (koki o ka hoʻomaha ʻAʻole i like a i ʻole like me ka 38 degere) a ua hui pū ʻia me nā mea paʻa (e like me PVDF) e hana i kahi ʻōnaehana slurry paʻa; I ka wā o ke kaʻina hana compaction, loaʻa iā ia ka plasticity ikaika a ʻaʻole kūpono i ka haki ʻana o ka particle, e hōʻoiaʻiʻo ana i nā ʻano mechanical o ka electrode a me ka hoʻololi ʻana i nā laina hana coating automated.

 

 

4. Nā Wahi noi nui

(1) Mana Lithium Battery Field

Hoʻohana ʻia no ka hana ʻana i nā electrodes kūlohelohe graphite no nā ʻenekini kaʻa kaʻa hou, me ka conductivity kiʻekiʻe a me nā hiʻohiʻona polarization haʻahaʻa, hoʻomaikaʻi ia i ka helu pākaukau a me ka hoʻokuʻu ʻana i ka hana (kākoʻo ʻana i ka 1C-3C wikiwiki wikiwiki), ʻoiai e hōʻoiaʻiʻo ana i ke ola pōʻaiapuni ma mua o 2000 mau manawa, e hālāwai ana i nā pono o ke kaʻa a me ke ola lawelawe.

He kūpono no ka pākaukau lithium electrodes i loko o nā keʻena mana mālama ikehu (e like me ka photovoltaic a me ka mana makani e kākoʻo ana i ka mālama ʻana i ka ikehu), hiki i ka ʻike haumia haʻahaʻa ke hoʻemi i ka pākuʻi ponoʻī-ka hoʻokuʻu ʻana (ka hoʻokuʻu ʻana iho o kēlā me kēia mahina ma lalo o 3%), a ʻo ka hana graphitization paʻa e hōʻoia i ka haʻahaʻa haʻahaʻa haʻahaʻa o ka pākaukau {0}4} manawa lōʻihi{{0} hoʻohaʻahaʻa ʻana o nā pōʻai ma lalo a i ʻole like me 15%).

(3) Mea Hoʻohana Electronics Lithium Battery Field

Hoʻohana ʻia ma ke ʻano he electrode maikaʻi ʻole no nā pā lithium i nā mea uila uila e like me nā smartphones a me nā laptops, hiki i ka puʻupuʻu nui o nā mea i hoʻopili ʻia ke hiki ke hoʻemi i ka electrode (ka mānoanoa electrode I lalo a i ʻole like me 80μm) a hoʻomaikaʻi i ka ikehu o ka pākaukau (me ke kiʻekiʻe -hiki i nā electrodes maikaʻi, hiki iā ia ke loaʻa ka nui o ka ikehu volumetric o ʻoi aku a i ʻole like me 4.5Wh/cm³W).

(4) Kūikawā Battery Lithium Field

Hoʻohana ʻia ma ke ʻano he electrode maikaʻi ʻole no nā pākahi lithium ma nā wahi wela -kiʻekiʻe (e like me nā ʻenehana hoʻomalu ʻenehana) a i ʻole -kahi wela haʻahaʻa (e like me nā mea hana waho), mālama ka pākaukau i ka hana hoʻokuʻu paʻa (ka nui o ka paʻa ʻana ma mua o 80%) ma ka degere -20 degere -60 degere a me ka hoʻoponopono ʻana i ka maʻiʻo haumia.
