ʻO ke kuleana o ka nickel mesh i loko o nā pākahi nickel-metal hydride
ʻO ka pākaukau nickel-metal hydrideʻo ia ka pila lua e hoʻopaʻa hou ʻia. ʻO kāna kumu hana e mālama a hoʻokuʻu i ka ikehu uila ma o ka hopena kemika ma waena o ka nickel metala (Ni) a me ka hydrogen (H). He mau hana koʻikoʻi ka nickel mesh i loko o nā pihi NiMH.
Hoʻohana nui ʻia ka nickel meshma ke ʻano he mea electrode i loko o nā pākahi nickel-metal hydride, a hoʻopili ʻo ia i ka electrolyte e hana i wahi no nā hopena electrochemical. Loaʻa iā ia ka conductivity uila maikaʻi loa a hiki ke hoʻololi pono i ka hopena electrochemical i loko o ka pākaukau i ke kahe o kēia manawa, a laila e ʻike ai i ka puka o ka ikehu uila.
Nickel uea mesh no hoi i maikai structural paʻa. I ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, hiki i ka nickel wire mesh ke mālama i kekahi ʻano a me ke kūpaʻa dimensional a pale i nā pilikia palekana e like me ke kaapuni pōkole kūloko a me ka pahū ʻana o ka pā. I ka manawa like, kōkua kona ʻano porous i ka electrolyte e puʻunaue like a komo, e hoʻomaikaʻi i ka hana pono o ka pākaukau.
Kahi mea hou aʻe, nickel wire mesh no hoi kekahi catalytic hopena. I ka wā o ke kaʻina hana a me ka hoʻokuʻu ʻana, hiki i nā mea catalytically active ma ka ʻili o ka nickel mesh ke hoʻoikaika i ka hopena electrochemical a hoʻomaikaʻi i ka hoʻopiʻi ʻana a me ka hoʻokuʻu ʻana a me ke ola lawelawe o ka pākaukau.
Hāʻawi ka porosity a me ka ʻāpana kikoʻī kikoʻī o ka nickel mesh me ka hana maikaʻi loa ma ke ʻano he mea electrode. Hāʻawi kēia i nā pūnaewele reactive hou aʻe i loko o ka pākaukau, e hoʻonui ana i ka nui o ka ikehu a me ka mana o ka pā. I ka manawa like, kōkua pū kēia ʻano hana i ke komo ʻana o ka electrolyte a me ka diffusion o ke kinoea, e mālama i ka hana paʻa o ka pā.
E hōʻuluʻulu, He mea ko'iko'i ka nickel mesh i loko o ka nickel-metal hydride batteries. Ma ke ʻano he mea electrode, loaʻa iā ia ka conductivity maikaʻi loa, ka paʻa ʻana o ke kūkulu ʻana a me ka hopena catalytic, e hāpai ana i ke kaʻina hana electrochemical i loko o ka pā. ʻO kēia mau hiʻohiʻona e hoʻohana nui ʻia i nā ʻāpana nickel-metal hydride i ka ikehu kiʻekiʻe, ka mana mana a me ke ola lōʻihi, a hoʻohana nui ʻia i nā polokalamu uila kelepona, nā kaʻa uila, nā ʻōnaehana mālama ikehu a me nā kula ʻē aʻe. Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, e hoʻonui ʻia a hoʻomaikaʻi ʻia ka hana a me ka hoʻohana ʻana i nā pāhana nickel-metal hydride.
