ʻO ka hoʻolauna ʻana o nā mea anode a me nā mea cathode o ka pā lithium ion

ʻO ka pākaukau lithium a me ka pākaukau lithium ion (no ka pākaukau lithium polymer pū kekahi), ʻo ka pā lithium he pākaukau e hoʻohana ana i ka metala lithium a i ʻole ka lithium alloy ma ke ʻano he cathode. ʻO ke ʻano kemika o ka metala lithium he mea ikaika loa ia, no laila e pono ai ka metala lithium i nā koi koʻikoʻi ma ke kaiapuni no kāna kaʻina hana, mālama a me ka noi. ʻO ka mea cathode o ka pākaukau lithium ion he mea hana intercalated e like me ke kalapona. ʻOi aku ka palekana o ka pākaukau Lithium no ka mea ʻo Li ion wale nō e hoʻouna ma waena o ka anode a me ka cathode i loko o ka pā. E like me ka lithium ion pākaukau a pākahi lithium polymer, ʻO ka electrolyte o ka pākaukau lithium ion he ʻano wai, ʻoiai ʻo ka pahu lithium polymer he gel a i ʻole ke kūlana paʻa, kahi e palekana ai ka pākaukau.

ʻO ka mea mua

ʻO ka inoa ʻepekema o ka pākaukau lithium ion ʻo ia ka lithium lua, me nā mea cathode e pili ana. ʻOkoʻa mai ka pākaukau lithium mua e pili ana i ka lithium ma ke ʻano he electrode hoʻokahi, ʻo ka pākaukau lua lithium he electrolyte wai e hoʻohui ai i ka LiPF6 a me LiClO4 i loko o ka electrolyte o DMC:EC(v:v=1:1). Ua hoʻololi ʻia kekahi mau mea electrolyte, akā ʻo ka pā lua lithium he pā wai wai.

I ka ʻōlelo o nā mea i loko o ka pākaukau lithium polymer, ʻo kāna electrolyte he polymer, maʻamau ka gel electrolyte a me ka electrolyte paʻa. Ua hoʻokumu ʻo South Korea i ka pākaukau gel me ka PEO-ion e like me ka electrolyte. ʻAʻole ʻike ʻia inā aia kēia ʻano pākaukau ma GalaxyRound a i ʻole LGGFlex.

ʻO ka lua

Aia kekahi mau ʻokoʻa ma waena o ka pākaukau lithium polymer a me ka pā lithium. Loaʻa i ka pākaukau Lithium ka pūʻolo kila kila (18650 a i ʻole 2320), ʻoiai ʻo ka lithium polymer pākahiko i hoʻopaʻa ʻia e ka pahu kiʻi ʻoniʻoni alumini, i kapa ʻia ʻo pouch cell.

Loaʻa i kekahi pākaukau lithium ka electrolyte paʻa paʻa, e like me LiPON, NASICON, perovskite, LiSICON, ka electrolyte ceramic me ka conductivity kiʻekiʻe a i ʻole ka electrolyte aniani i hana ʻia e ka mea amorphous. Aia paha ia i ka pākaukau lua lithium.

ʻO nā mea a pau, hiki ke hoʻokaʻawale ʻia ka pākaukau lithium i ʻelua mau ʻāpana: lithium metal battery a me ka lithium ion battery. ʻO ka maʻamau, ʻaʻole hiki ke hoʻihoʻi ʻia ka pākaukau metala lithium me ka lithium metala, ʻoiai ʻaʻole i loaʻa i ka pākaukau lithium ion ka lithium metala akā hiki ke hoʻouka hou ʻia. He ʻokoʻa koʻikoʻi ka pākaukau Lithium, lithium ion battery a me lithium polymer battery.
