ʻO nā Electrolyte Polymer Paʻa a pau no ka Battery Lithium Ion

Ua lilo ka mana kemika i mea e pono ai ka mālama ʻana i ka ikehu no nā kānaka.I loko o ka ʻōnaehana pākahi kemika i kēia manawa,ka pākaukau lithiummanaʻo ʻia ʻo ia ka mea ʻoi loamālama ikehumea ma muli o kona ikehu kiʻekiʻe, lōʻihi ka pōʻai ola, a ʻaʻohe hopena hoʻomanaʻo.I kēia manawa, hoʻohana nā pākahi lithium-ion kuʻuna i nā electrolytes wai kūlohelohe.ʻOiai hiki i nā electrolytes wai ke hāʻawi i ka conductivity ionic kiʻekiʻe a me ka pilina pili maikaʻi, ʻaʻole hiki ke hoʻohana palekana ʻia i nā ʻōnaehana lithium metala.He haʻahaʻa ko lākou lithium ion migration a maʻalahi ke kahe.ʻO nā pilikia e like me ka volatile, flammable, a me ka palekana maikaʻi ʻole ke keʻakeʻa i ka hoʻomohala hou ʻana o nā pā lithium.Ke hoʻohālikelike ʻia me nā electrolytes wai a me nā electrolytes solid inorganic, loaʻa i nā electrolytes polymer all-solid nā mea maikaʻi o ka hana palekana maikaʻi, ka maʻalahi, ka hana maʻalahi i nā kiʻiʻoniʻoni, a me ka pilina pili maikaʻi.I ka manawa like, hiki iā lākou ke pale i ka pilikia o ka lithium dendrites.I kēia manawa, ua loaʻa ka manaʻo nui i kēia manawa, ʻoi aku ka kiʻekiʻe o nā poʻe i nā ʻoihana lithium-ion e pili ana i ka palekana a me ka ikaika o ka ikehu.Ke hoʻohālikelike ʻia me nā pākahi lithium-ion o nā ʻōnaehana kūlohelohe wai kuʻuna, ʻoi aku ka maikaʻi o nā pākahi lithium all-solid-state ma kēia ʻano.Ma ke ʻano he kumu nui o nā ʻeke lithium pauku paʻa, ʻo nā electrolytes polymer solid-state kekahi o nā kuhikuhi hoʻomohala koʻikoʻi o ka noiʻi pākaukau lithium āpau āpau.No ka hoʻohana maikaʻi ʻana i nā electrolytes polymer a pau i nā pākahi lithium pāʻoihana, pono ia e hoʻokō i nā koi aʻe. ʻO ka puka aniani electrochemical kokoke i 5V, maikaʻi kemika thermal paʻa, a me ke kaiapuni a me ka maʻalahi hoʻomākaukau.

E hoʻomaka ana mai ke ʻano o ka lawe ʻana i ka ion i nā electrolytes polymer paʻa a pau, ua hana nā mea noiʻi i nā hana hoʻololi he nui, e like me ka hui ʻana, copolymerization, ka hoʻomohala ʻana i nā electrolytes polymer conductor hoʻokahi, nā electrolytes polymer kiʻekiʻe, hoʻohui i nā plasticizers, E lawe i ke keʻa- ka hoʻopili ʻana a me ka hoʻomohala ʻana i ka ʻōnaehana hoʻohuihui organik/inorganic.Ma o kēia mau hana noiʻi, ua hoʻomaikaʻi maikaʻi ʻia ka hana holoʻokoʻa o ka polymer electrolyte paʻa paʻa a pau, akā hiki ke ʻike ʻia ʻaʻole pono e loaʻa ka polymer electrolyte paʻa paʻa i ka wā e hiki mai ana ma o ke ʻano hoʻololi hoʻokahi, akā he nui. nā ʻano hoʻololi.Huihui.Pono mākou e hoʻomaopopo pono i ka mīkini hoʻololi, koho i ke ʻano hoʻololi kūpono no ka manawa hewa, a hoʻomohala i kahi electrolyte polymer paʻa paʻa i hiki ke hoʻokō maoli i nā pono o ka mākeke.
