ʻO ka pahu uila kaʻa a me ka pahu pahu Liion

2. Mea hoʻoikaika kino:

a) E nānā inā pololei ka ratio hui ʻana a me ka nui ma ke kaupaona ʻana a me ka hui ʻana;

b) Ka wili pōlele: ka manawa wili o nā electrodes maikaʻi a maikaʻi ʻole;ka lakio o nā ʻeke agate i ka hui ʻana i loko o ka pahu wili kinipōpō;ka ratio o na kinipopo nui me na pōpō liʻiliʻi o ka pōpō agate;

c) Baking: hoʻonohonoho ʻana i ka mahana a me ka manawa bakena;e ho'āʻo i ka mahana ma hope o ka hoʻomaloʻo ʻana ma hope o ka kuke ʻana.

d) Ka hui ʻana a me ka hoʻoulu ʻana o nā mea hana a me ka hopena: ke ʻano hoʻoulu ʻana, ka manawa hoʻoulu a me ka pinepine.

e) kānana: hele 100 mesh (a i ʻole 150 mesh) kānana molekala.

f) Ka ho'āʻo a me ka nānā ʻana:

E hoʻokō i kēia mau hoʻāʻo ʻana i ka slurry a me ka hui ʻana: ka ʻike paʻa, viscosity, ka maikaʻi o ka hui ʻana, ka tap density, ka slurry density.

Ma waho aʻe o ka hana maʻemaʻe o ke kaʻina hana kuʻuna, pono nō hoʻi e hoʻomaopopo i nā kumu kumu o ka paʻi pākahi lithium.

ʻO ka manaʻo Colloid

 

ʻO ka hopena nui o ka hoʻoulu ʻana o nā ʻāpana colloidal ʻo ia ka ikaika van der Waals ma waena o nā ʻāpana.No ka hoʻonui ʻana i ka paʻa o nā ʻāpana colloidal, ʻelua mau ala.ʻO kekahi e hoʻonui i ka repulsion electrostatic ma waena o nā ʻāpana colloidal, a ʻo kekahi e hana i kahi ākea ma waena o nā pauka.No ka pale ʻana i ka hoʻohui ʻana o nā pauka ma kēia mau ala ʻelua.

ʻO ka ʻōnaehana colloidal maʻalahi loa i haku ʻia me kahi pae hoʻopuehu a me kahi mea hoʻopuehu, kahi o ka pālākiō o ka māhele hoʻopuehu mai 10-9 a 10-6m.Pono nā mea i loko o ka colloid e loaʻa i kahi pae o ka hiki ke hoʻopuehu i loko o ka ʻōnaehana.E like me nā mea hoʻoheheʻe like ʻole a me nā ʻāpana i hoʻopuehu ʻia, hiki ke hana ʻia nā ʻano colloidal like ʻole.No ka laʻana, ʻo ka noe he aerosol kahi e hoʻopuehu ʻia ai nā kulu i loko o ke kinoea, a ʻo ka toothpaste he sol kahi e hoʻopuehu ʻia ai nā ʻāpana polymer paʻa i loko o kahi wai.

 

Nui ka hoʻohana ʻana o nā colloids i ke ola, a pono e ʻokoʻa nā waiwai kino o nā colloids ma muli o ke kaʻina disperse a me ka medium dispersion.Ke nānā nei i ka colloid mai kahi microscopic o ka nānā ʻana, ʻaʻole mau nā ʻāpana colloidal, akā e neʻe like ʻole i ka waena, ʻo ia ka mea a mākou e kapa ai i ka neʻe Brownian (Brownian motion).Ma luna aʻe o ka ʻole ʻole, e komo nā ʻāpana colloidal i ka neʻe Brownian ma muli o ka neʻe wela.ʻO kēia ka dynamics o nā microscopic colloids.Kū'ē nā ʻāpana colloidal ma muli o ka neʻe ʻana o Brownian, ʻo ia ka manawa kūpono no ka hōʻuluʻulu ʻana, ʻoiai aia nā ʻāpana colloidal i kahi kūlana thermodynamically unstable, no laila, ʻo ka ikaika o ka launa pū ʻana ma waena o nā ʻāpana kekahi o nā kumu nui no ka hoʻopuehu.
