Lithium hexafluorophosphate CAS:21324-40-3

He kuleana koʻikoʻi ko Lithium hexafluorophosphate i ka ʻenehana pākahi lithium-ion hiki ke hoʻouka hou ʻia, kahi e lawelawe ai ma ke ʻano he ʻāpana electrolyte pono ʻole. Ma ka hoʻoheheʻe ʻana i loko o nā mea hoʻoheheʻe organik, hāʻawi ʻo LiPF6 i nā cations lithium a me nā anions hexafluorophosphate e hiki ai ke alakaʻi ionic i loko o ka ʻōnaehana pākahi. Hoʻolaha kēia i ka neʻe ʻana o nā ions lithium ma waena o ka anode a me ka cathode i ka wā o nā pōʻaiapuni hoʻouka a me ka hoʻokuʻu ʻana, e hoʻomaʻamaʻa ana i ke kahe o ke au uila a hāʻawi i ka hana holoʻokoʻa o ka pākahi. ʻO ka hoʻohana ʻana iā LiPF6 ma ke ʻano he paʻakai electrolyte e hoʻonui i ka nui o ka ikehu, ke kūpaʻa voltage, a me ka pono o ka pōʻaiapuni o nā pākahi lithium-ion, e lilo ia i mea nui i ka hoʻoikaika ʻana i nā mea uila lawe lima, nā kaʻa uila, a me nā ʻōnaehana mālama ikehu paʻa. Eia kekahi, hiki i ka lithium hexafluorophosphate ke hoʻomohala i nā pākahi lithium-ion hana kiʻekiʻe me ka palekana i hoʻomaikaʻi ʻia a me ke kūpaʻa wela. Kākoʻo kona kūlike me nā mea electrode like ʻole a me nā ʻano electrolyte i ka holomua o nā ʻenehana pākahi hanauna hou, me nā pākahi solid-state a me lithium-sulfur. Eia kekahi, loaʻa i kēia hui ka noi i ka hana ʻana o nā electrolytes kūikawā no nā noi niche e like me ka aerospace, nā mea lapaʻau, a me ka mālama ikehu grid-scale, kahi e pono ai nā koi hana koʻikoʻi. Ma keʻano holoʻokoʻa, kū ka lithium hexafluorophosphate ma ke ʻano he mea nui e hiki ai i ka ʻenehana pākahi lithium-ion, e hoʻokele ana i nā holomua i ka mālama ʻana i ka ikehu a me ka electrification ma nā ʻāpana like ʻole.
