ʻO ka pākaukau lithium ion maʻalahi

He ʻenehana hou nā pākahi lithium ion hiki ke maʻalahi (a i ʻole stretchable) i ke kahua e puka mai nei o ka uila uila. Hiki iā lākou ke hoʻohana i nā mea hiki ke hoʻohana ʻia, a me nā mea ʻē aʻe me ka ʻole o ka ʻoʻoleʻa a me ka puʻupuʻu e like me ka ʻenehana pākaukau o kēia manawa.

He pōmaikaʻi kēia no ka mea ʻo ka nui o ka pākaukau kekahi o nā mea paʻa i ka wā e hoʻolālā ai i kahi huahana maʻalahi e like me ka smartwatch a i ʻole ka mīkina lima kikohoʻe. Ke hilinaʻi nui nei ko mākou kaiaulu i nā smartphones a me nā mea hiki ke hoʻohana ʻia, ke manaʻolana nei mākou e piʻi aʻe ka pono o ka mālama ʻana i ka ikehu i loko o kēia mau huahana ma mua o ka mea hiki ke loaʻa i nā ʻenekini o kēia lā; akā naʻe, ua hoʻohuli ʻia ka nui o nā hui e hoʻomohala nei i kēia mau mea hana mai ka hoʻohana ʻana i nā ʻenehana pākaukau maʻalahi ma muli o ko lākou nele i ka hiki ke hoʻohālikelike ʻia me nā pā lithium-ion maʻamau i loaʻa i nā smartphones.

Ma ka hoʻohana ʻana i ka polimer lahilahi a hiki ke emi ma kahi o nā mea hōʻiliʻili metala maʻamau a

nā mea hoʻokaʻawale i kahi hana anode/cathode maʻamau, ua hoʻopau ʻia ka pono o nā electrodes metala mānoanoa.

ʻAe kēia i kahi lakio ʻoi aku ka kiʻekiʻe o ka ʻāpana electrode i ka leo i hoʻohālikelike ʻia me nā ʻāpana cylindrical maʻamau. ʻO kekahi pōmaikaʻi nui e hele mai me kēia ʻenehana ʻo ia ka hiki ke hoʻolālā ʻia mai ka hoʻomaka ʻana i ka hana ʻana ma mua o ka noʻonoʻo ʻana e like me ka mea maʻamau i kēia lā.

No ka laʻana, hoʻokomo pinepine nā mea hana kelepona i nā kua plastik a i ʻole nā ​​​​bumpers no ka pale ʻana i nā pale aniani no ka mea ʻaʻole hiki iā lākou ke hoʻokō i kahi hoʻolālā kūlohelohe ʻoiai e paʻa mau ana (ʻo ia hoʻi, fused polycarbonate). Hiki ke maʻalahi nā pākahi lithium ion mai ka hoʻomaka ʻana no laila ʻaʻole i loaʻa kēia mau pilikia.

ʻOi aku ka māmā ma mua o nā pākahi maʻamau

Aia ka ʻenehana ʻenehana maʻalahi i kona wā kamaliʻi, ʻo ia hoʻi he nui ka lumi no ka hoʻomaikaʻi ʻana. ʻAʻole i lawe ka nui o nā ʻoihana i kēia manawa kūpono no ka nele o ko lākou hiki ke hoʻohālikelike ʻia i nā ʻenehana paʻa. Ke hoʻomau nei ka noiʻi, e hoʻopau ʻia kēia mau hemahema a e hoʻomaka maoli kēia ʻenehana hou. ʻOi aku ka māmā o nā ʻanikini maʻamau ma mua o nā pākahi maʻamau, ʻo ia hoʻi, hiki iā lākou ke hāʻawi i nā mana hou aʻe i kēlā me kēia ʻāpana paona a i ʻole ka leo ʻoiai ʻoi aku ka liʻiliʻi o ka lumi—he pōmaikaʻi ʻike ʻia ke kūkulu ʻana i nā huahana i manaʻo ʻia no ka hoʻohana ʻana i nā mea liʻiliʻi e like me nā wati akamai a i ʻole nā ​​​​pepeiao.

ʻOi aku ka liʻiliʻi o ka wāwae wāwae i hoʻohālikelike ʻia me nā pākahi lithium ion maʻamau

Haʻahaʻa haʻahaʻa kiko'ī ikehu

ʻOi aku ka haʻahaʻa haʻahaʻa o ka ikehu kikoʻī ma mua o ko lākou mau mea maʻamau. 'O ia ho'i, hiki iā lākou ke mālama ma kahi o 1/5 e like me ka nui o ka uila no kēlā me kēia'āpana kaumaha a me ka leo e like me nā pākahi lithium ion ma'amau. ʻOiai he ʻokoʻa kēia ʻokoʻa, ʻaʻole ia i hoʻohālikelike ʻia i ka hiki ke hana ʻia nā pākahi lithium ion maʻalahi me kahi wahi electrode i ka ratio volume o 1000: 1 ʻoiai ʻo ka pahu cylindrical maʻamau he wahi i ka ratio volume o ~ 20:1. No ka hāʻawi ʻana iā ʻoe i ka manaʻo i ka nui o kēia ʻāpana helu, ua kiʻekiʻe loa ʻo 20:1 i ka hoʻohālikelike ʻia me nā pākaukau ʻē aʻe e like me ka alkaline (2-4:1) a i ʻole lead-acid (3-12:1). I kēia manawa, ʻo 1/5 wale nō ke kaumaha o kēia mau ʻona o nā pākahi lithium ion maʻamau, akā ke hoʻomaka nei ka noiʻi e hoʻomāmā.

ʻO nā pākiki maʻalahi ka wā e hiki mai ana o nā mea uila hiki ke hoʻohana. Ke hilinaʻi nui nei ko mākou kaiāulu i nā mea akamai e like me nā smartphones, e ʻoi aku ka maʻamau o nā mea lole ma mua o kēia mau lā. Manaʻo mākou e hoʻohana nā mea hana i kēia manawa kūpono ma o ka hoʻohana ʻana i nā ʻenehana pākaukau maʻalahi i kā lākou huahana ma mua o ka hoʻomau ʻana i ka hilinaʻi ʻana i ka ʻenehana lithium ion maʻamau i hiki ʻole i kēia mau ʻano huahana hou.
