ʻO nā pākahi Lithium e hoʻololi i ko mākou ola

Pehea ka hana ʻana o nā ʻeke lithium-ion i ka uila

ʻO ke kumu hana maʻamau o nā pila he mea like, e pili ana i kahi electrode maikaʻi (cathode), kahi electrode ʻino (negative electrode), a me kahi electrolyte. I loko o ka pākaukau, hiki i ka electrolyte ke hele i nā ion, ʻoiai ke kahe ʻana o nā electrons mai ka electrode maikaʻi ʻole i ka electrode maikaʻi, a laila e hoʻohua ai i ka uila. No nā ʻāpana lua, e like me nā pākahi lithium-ion, hiki iā lākou ke mālama i nā electrons i loko o ka electrode maikaʻi ʻole ma mua o ka hoʻouka ʻana, a i ka wā e hoʻokuʻu ʻia ai ka pākaukau, kahe kēia mau electrons i ka electrode maikaʻi, a laila e hoʻohua ai ka uila.

A laila, e nānā kākou i nā hiʻohiʻona a me nā pono o nā pā lithium-ion. ʻO ke kumu o ke kū ʻana o nā pā lithium-ion i waena o nā ʻāpana he nui ma muli o ko lākou ʻano kūʻokoʻa a me ke koho ʻana i nā mea. ʻO ka mea mua, hoʻohana nā pākahi lithium-ion i nā pūhui metala i loko o ka lithium ma ka electrode maikaʻi a me ke kalapona (e like me ka graphite) hiki ke hoʻopaʻa a mālama i ka lithium ma ka electrode maikaʻi ʻole. Hiki i kēia hoʻolālā ke hiki i nā pā lithium-ion ke hoʻohua i ka uila me ka ʻole o ka pono e hoʻoheheʻe i nā electrodes ma ka hoʻoheheʻe ʻana i ka electrolyte e like me nā pila kuʻuna, a laila e hoʻolohi i ka ʻelemakule o ka pā. ʻO ka lua, ʻo ka lithium kahi mea liʻiliʻi a māmā hoʻi, ka mea e hana ai i nā pā lithium-ion i ʻoi aku ka paʻakikī a me ka māmā ma ka mana like. Eia kekahi, ua loaʻa i nā pā lithium-ion nā pōmaikaʻi o ke kiʻekiʻe o ka ikehu kiʻekiʻe, ka lōʻihi o ke ola holoʻokoʻa, a ʻaʻohe hopena hoʻomanaʻo, ʻo ia mau mea a pau i hana i nā pā lithium-ion i hoʻohana nui ʻia i nā mea uila uila, nā kaʻa uila a me nā kahua ʻē aʻe.
