ʻO nā kinikini Zinc me nā haʻi liʻiliʻi. Kiʻekiʻe ikehu kiʻekiʻe a me nā kaukani o nā pōʻai hana
ʻO nā pākahi Lithium-ion ka maʻamau a me ka pae hoʻohālikelike i ka mālama ʻana i ka ikehu. Akā ke ʻimi mau nei ka poʻe noiʻi i nā mea e hāʻawi ana i ka hana like ʻole ma nā kumukūʻai haʻahaʻa haʻahaʻa. ʻO kekahi o nā mea hoʻohiki ʻo ka zinc (Zn).
ʻO nā pākahi Zn-x he mea kūʻai loa ia. Pono lākou e uku
Hoʻopuehu ʻia nā waihona Zinc ma ka honua holoʻokoʻa, hiki iā mākou ke loaʻa iā lākou ma Polani - ma ke ʻano he hui mākou i hoʻohana iā lākou mai ka makahiki 2020 (!) A hiki i ka hopena o 12,9 mau makahiki. ʻO Zinc kahi metala haʻahaʻa a maʻalahi ka loaʻa ʻana ma mua o ka lithium no ka mea he mea pono ia i ka ʻoihana, ʻoi aku ka nui o ka hana honua i nā miliona (2019 miliona ma 82) ma mua o nā ʻumi kaukani tons (2020 tausani ma XNUMX) e like me ka manaʻo. kau ma ka palapala. Eia kekahi, ʻo ka zinc ke kumu o nā cell mai ka XNUMXth century a hoʻohana mau ʻia i nā cell disposable (no ka laʻana, nā cell alkaline e pili ana i ka zinc oxide a me ka manganese).
ʻO ka paʻakikī ka loaʻa ʻana o nā pūnae zinc e holo no ka liʻiliʻi he mau haneli mau haneli me ka mālama ʻana i ka mana i hoʻolālā ʻia.... ʻO ke kaʻina hana o ka hoʻopaʻa ʻana i kahi pākaukau me kahi anode zinc ke kumu i ka waiho ʻole ʻana o nā ʻātoma metala ma ka electrode, a mākou i ʻike ai he ulu dendrite. Ke ulu nei nā Dendrites a hiki i ka wā e haki ai lākou i nā mea hoʻokaʻawale, hiki i ka lua electrode, hana i kahi pōkole pōkole, a make ke kelepona.
I Mei 2021, ua paʻi ʻia kahi pepa ʻepekema kahi i wehewehe ʻia ai ke ʻano o ke kelepona me kahi electrolyte i hoʻonui ʻia me nā paʻakai fluorine. Hoʻopili nā paʻakai me ka zinc ma ka ʻili anode e hana i ka zinc fluoride. Hiki ke komo i ka papa hui i nā ion, akā ua pale i nā dendrites.... Eia naʻe, ʻaʻole makemake maoli ka mea i pale ʻia ma kēia ʻano e hoʻihoʻi i ka uku (he kūʻē kūʻokoʻa kiʻekiʻe, kahi kumu).
ʻO kahi ala hiki ke hoʻonui i kona reactivity ua wehewehe ʻia ma kahi pepa noiʻi ʻē aʻe i hoʻolaʻa ʻia i nā cathodes cell zinc ma muli o ke keleawe, phosphorus a me ka sulfur. Nā hopena? ʻOiai ke hāʻawi nei ke kelepona zinc maʻamau i nā density ikehu a hiki i ka 0,075 kWh / kg, nā pūnaewele zinc-air hou loa me nā cathodes hou. hoʻohiki 0,46 kWh / kg... ʻAʻole e like me nā pūnaewele Zn-air mua, i hoʻohana mau ʻia, pono lākou e mau mau kaukani o nā pōʻai hana, 'o ia ho'i, kūpono no ka 'oihana (kumu).
Inā hiki ke hoʻohui ʻia nā ʻike āpau, hōʻoia ʻia a hoʻonui ʻia ka hana, hiki i nā pūnae zinc ke lilo i kumu no ka mālama ʻana i ka ikehu i ka wā e hiki mai ana.
Kiʻi wehe: hiki ke hoʻohana hou ʻia ka zinc ("alkaline battery"). Ma muli o ka hohonu o ka hoʻokuʻu ʻana, hiki iā ia ke kūpaʻa mai kekahi mau haneli mau haneli hana (c) Lukas A CZE
E hoʻomaopopo mai ka poʻe hoʻoponopono o www.elektrowoz.pl: Ma ka ʻōlelo Pelekania, ua kapa ʻia ʻo zinc air cell no ka lawe ʻana i ka oxygen mai ka lewa. Mai ko mākou manaʻo, ʻaʻole ia he mea nui inā hiki ke hoʻohuli ʻia ke kaʻina hana, ʻo ia hoʻi, hiki ke hoʻopiʻi a hoʻokuʻu ʻia nā cell i nā manawa he nui.
