Ka Noi ʻOihana o ka Electrolytic Copper Foil:

Ma ke ʻano he hoʻokahi o nā mea kumu o ka ʻoihana uila, hoʻohana nui ʻia ka pepa keleawe electrolytic no ka hana ʻana i ka papa kaapuni paʻi (PCB), nā pila lithium-ion, i hoʻohana nui ʻia i nā mīkini home, kamaʻilio, helu kamepiula (3C), a me ka ʻoihana ikehu hou. I nā makahiki i hala iho nei, ua koi ʻia nā koi koʻikoʻi a me nā koi hou no ka pepa keleawe me ka hoʻomohala ʻana o ka ʻenehana 5G a me ka ʻoihana pila lithium. ʻO ka pepa keleawe haʻahaʻa loa (VLP) no 5G, a me ka pepa keleawe lahilahi loa no ka pila lithium e hoʻomalu i ke kuhikuhi hoʻomohala hou o ka ʻenehana pepa keleawe.

Ke Kaʻina Hana Hana ʻana o ka Electrolytic Copper Foil:

ʻOiai hiki ke ʻokoʻa nā kikoʻī a me nā waiwai o ka foil keleawe electrolytic me kēlā me kēia mea hana, ua like ke kaʻina hana. Ma keʻano laulā, hoʻoheheʻe nā mea hana foil āpau i ke keleawe electrolytic a i ʻole ka uea keleawe ʻōpala, me ke keleawe electrolytic maʻemaʻe like i hoʻohana ʻia ma ke ʻano he mea maka, i loko o ka waikawa sulfuric e hana i kahi hopena wai o ke keleawe sulfate. Ma hope o kēlā, ma ka lawe ʻana i ka wili metala ma ke ʻano he cathode, ua electrodeposited ke keleawe metala ma luna o ka ʻili o ka wili cathodic mau ma o ka hopena electrolytic. Hoʻokaʻawale mau ʻia mai ka wili cathodic i ka manawa like. Ua ʻike ʻia kēia kaʻina hana ʻo ke kaʻina hana foil a me ka electrolysis. ʻO ka ʻaoʻao i wehe ʻia (ʻaoʻao laumania) mai ka cathode ka mea i ʻike ʻia ma ka ʻili o ka papa laminated a i ʻole PCB, a ʻo ka ʻaoʻao hope (i ʻike nui ʻia ʻo ka ʻaoʻao ʻino) ka mea i kau ʻia i kahi moʻo o nā mālama ʻili a ua hoʻopaʻa ʻia me ka resin i loko o ka PCB. Hoʻokumu ʻia ka foil keleawe ʻelua ʻaoʻao ma ka kaohi ʻana i ka nui o nā mea hoʻohui organik i loko o ka electrolyte i ke kaʻina hana o ka hana ʻana i ka foil keleawe no ka pākahi lithium.

I ka wā o ka electrolysis, neʻe nā cations i loko o ka electrolyte i ka cathode, a hoʻemi ʻia ma hope o ka loaʻa ʻana o nā electrons ma ka cathode. Hoʻopau ʻia nā anions ma hope o ka neʻe ʻana i ka anode a me ka nalowale ʻana o nā electrons. Hoʻopili ʻia ʻelua mau electrodes i loko o ka hopena keleawe sulfate me ke au pololei. A laila, e ʻike ʻia ua hoʻokaʻawale ʻia ke keleawe a me ka hydrogen ma ka cathode. Penei ka hopena:

Cathode: Cu2+ +2e → Cu 2H+ +2e → H2↑
Anode: 4OH- -4e → 2H2O + O2↑
2SO42-+2H2O -4e → 2H2SO4 + O2↑

Ma hope o ka mālama ʻana i ka ʻili cathode, hiki ke ʻili ʻia ka papa keleawe i waiho ʻia ma luna o ka cathode, e loaʻa ai kahi mānoanoa o ka pepa keleawe. ʻO ka pepa keleawe me kekahi mau hana i kapa ʻia he pepa keleawe.
