Hale Hana Bateri Lithium
By hoppt
He aha ka litiuma?
ʻO ka Lithium kahi mea kemika i hoʻohana ʻia i nā ʻano pākahi a pau, me ka maʻamau a me ka rechargeable. ʻO ka pākaukau lithium-ion ka ʻano pākaukau kaulana loa i hoʻohana ʻia i kēia lā.
Hana ʻana i nā Bateri Lithium Ion
ʻO ka hana mua i ka hana ʻana i kahi pākaukau lithium ion ʻo ka hana ʻana i ka anode, ka mea maʻamau i hana ʻia mai ke kalapona. Pono e ho'oma'ema'e a ho'oma'ema'e 'ia ka mea anode no ka wehe 'ana i kekahi naikokene, kahi e ho'omāhana ai ka mea anode i nā uku ki'eki'e. ʻO ka hana aʻe e hana ana i ka cathode a hoʻokomo iā ia i loko o ka anode me kahi conductor metala. Hele mai kēia mea hoʻokele metala i ke keleawe a i ʻole ke alumini.
ʻO ka hana ʻana i nā ʻanuʻu lithium ion hiki ke hana weliweli ma muli o ka hoʻohana ʻana i nā kemika e like me ka manganese dioxide (MnO2). Hoʻokuʻu ka manganese dioxide i nā uahi ʻawaʻawa ke hoʻomehana ʻia i nā wela kiʻekiʻe. ʻOiai e pono ana kēia mea kemika no nā ʻeke lithium ion, ʻaʻole hiki ke hoʻopili ʻia me ka ea a i ʻole ka makū no ka mea hiki iā ia ke hoʻokuʻu i ke kinoea ʻona (e hoʻomanaʻo i kaʻu i ʻōlelo ai ma mua?). No ka pale ʻana i kēia, loaʻa i nā mea hana kā lākou mau hoʻolālā ponoʻī no ka mālama ʻana i kēia mau kinoea i ka wā o ka hana ʻana e like me ka uhi ʻana i nā electrodes me ka mahu wai e pale aku ai i ka oxygen a me ka hoʻolaha ʻana i ka hydrogen.
E hoʻokomo pū nā mea hana i kahi mea hoʻokaʻawale ma waena o nā electrodes ʻelua, ka mea e pale ai i nā pōkole pōkole ma ka ʻae ʻana i nā ion e hele i loko akā ke kāohi nei i nā electrons mai ka hana ʻana pēlā.
ʻO kekahi ʻāpana koʻikoʻi o ka hana ʻana i nā pākahi lithium ion e hoʻohui i kahi electrolyte wai ma waena o nā electrodes ʻelua. Kōkua kēia wai electrolyte i ka hoʻokele ʻana i nā ion a hiki ke kahe ka uila ma waena o nā electrodes ʻelua me ka pale ʻana i kekahi electrode mai ka hoʻopā ʻana i kekahi, kahi e hoʻopōkole ai i ke ahi. Hoʻokahi wale nō i hoʻopau ʻia kēia mau ʻanuʻu a hiki iā mākou ke hana i kā mākou huahana hope loa: kahi pākahi lithium ion.
Hoʻohana nā pāka Lithium Ion i nā mea he nui a mākou e hoʻohana ai i kēlā me kēia lā. A me ko lākou ulu nui ʻana, ʻoi aku ka nui o nā ʻoihana e hana ana i nā mea pākaukau a me nā huahana. E like me kekahi ʻoihana, aia nā pōʻino i ka hana ʻana a me ka hoʻopau ʻana. Manaʻo mākou ua ʻike kēia ʻatikala, a ua ʻoi aku ka maikaʻi o kou ʻike ʻana i ka ʻoihana pākaukau Lithium.
