nā lako hana hoʻolāʻau lithium ion
ʻO ka mīkini e-waste recycling he mea hana i hoʻolālā ʻia e hana hou i ka ʻōpala uila.Hoʻohana maʻamau ʻia nā mīkini hoʻoheheʻe E-waste no ka hana hou ʻana i nā mea uila kahiko, e like me nā kamepiula, televise, a me nā kelepona paʻalima, inā ʻaʻole e hoʻolei ʻia a hoʻopau ʻia i loko o nā waihona ʻāina a puhi ʻia paha.
ʻO ke kaʻina hana o ka e-waste recycling maʻamau e pili ana i kekahi mau ʻanuʻu, e like me ka wehe ʻana, ka wehe ʻana, a me ka hana ʻana.Hoʻolālā ʻia nā mīkini hoʻoheheʻe E-waste e hoʻomaʻamaʻa i ka nui o kēia mau ʻanuʻu, e hana i ke kaʻina hana i ʻoi aku ka maikaʻi a me ke kumu kūʻai.
Hoʻohana kekahi mau mīkini hoʻoheheʻe e-waste i nā ʻano hana kino, e like me ka ʻoki ʻana a me ka wili ʻana, e wāwahi i nā ʻōpala uila i mau ʻāpana liʻiliʻi.Hoʻohana nā mīkini ʻē aʻe i nā kaʻina kemika, e like me ka leaching acid, e unuhi i nā mea waiwai e like me ke gula, ke kālā, a me ke keleawe mai nā ʻōpala uila.
Ke ulu nui nei nā mīkini hoʻoheheʻe E-waste i ka ulu ʻana o ka nui o nā ʻōpala uila i hana ʻia a puni ka honua.Ma ka hana hou ʻana i nā ʻōpala uila, hiki iā mākou ke hōʻemi i ka nui o nā ʻōpala e pau ana i nā ʻōpala, mālama i nā kumuwaiwai kūlohelohe, a hoʻemi i ka hopena o ke kaiapuni o nā mea uila.

ʻO ka haʻihaʻi a me ka hoʻokaʻawale ʻana i ka pākaukau lithium-ion a me ka mea kanu hana hou
No nā kaʻa uila, e like me nā huila ʻelua a i ʻole nā huila ʻehā.ʻElua ʻano maʻamau ka pākaukau lithium LiFePO4e like me ka anode a meLiNi0.3Co0.3Mn0.3O2.
Hiki i kā mākou mīkini ke hana i ka lithium-ion LiFePO4e like me ka anode a meLiNi0.3Co0.3Mn0.3O2. pākaukau.ʻO ka hoʻolālā e like me lalo:
- No ka uhaki ʻana i ka ʻeke ʻeke e hoʻokaʻawale a nānā i ke kumu kūpono a ʻaʻole paha.E hoʻouna ka pūʻolo pila i ka pūpū, nā mea, ka aluminika a me ke keleawe.
- E ʻoki ʻia a hoʻokaʻawale ʻia ke kumu uila kūpono ʻole.Aia ka crsher i ka pale lewa.He anaerobic thermolysis ka mea maka.E loaʻa kahi puhi kinoea hoʻopau e hoʻokō i ka ea luhi i ka pae i hoʻokuʻu ʻia.
- ʻO nā ʻanuʻu aʻe e hoʻokaʻawale me ka puhi ʻana i ka ea a i ʻole ka mana wai e hoʻokaʻawale i ka cathode a me ka pauka anode a me ke keleawe a me ka alumini a me ke poʻo puʻu, a me nā ʻōpala o ka pūpū.
