Batirin Lithium polymer

lithium polymer baturi

Lithium polymer baturi nau'in baturi ne mai caji a cikin ƙaramin nau'i. Waɗannan batura sun dace da na'urorin hannu waɗanda ke buƙatar fiye da watts 3 amma ƙasa da watts 7, kamar kwamfyutoci da wayoyin hannu. An sanya sunan baturan lithium polymer don cakuda ions lithium da polymers (wani abu mai manyan kwayoyin halitta) waɗanda ke yin aikinsu.

An ƙirƙira batirin lithium polymer kuma masu bincike ne suka ƙirƙira a ƙarshen 1980s. Na farko samfurin baturi na lithium polymer an ƙirƙira shi ne a cikin 1994 don amfanin gaggawa na likita, kuma bayan shekaru 10 da ƙirƙirar shi, an yi amfani da shi akan tauraron dan adam da jiragen sama. An yi amfani da baturin lithium polymer a cikin wayoyin hannu tun 2004, wanda shine lokacin da Sony ya samar da wayar hannu ta farko ta kasuwanci ta amfani da baturin lithium ion.

Batirin lithium polymer ya bambanta da baturan lithium ion saboda ba su da mai raba tsakanin ingantattun na'urorin lantarki da na wuta. Polymers da aka yi amfani da su a cikin waɗannan batura suna da daidaito kamar na jelly, wanda shine dalilin da ya sa ake kira su gel cell. Batirin lithium polymer suma suna da fa'idar kasancewa ƙasa da yuwuwar samun yaɗuwar electrolyte idan aka kwatanta da sauran nau'ikan batirin lithium ion saboda babu mai raba su.

Haɗarin yaɗuwar electrolyte har ma yana faruwa tare da wasu samfuran polymer waɗanda ba na lithium ba. Yayin da baturin ya yi kama da sauran baturan lithium ion, kayan da ake amfani da su a cikinsa sun bambanta da na baturan lithium ion na gargajiya. Ruwan lantarki mai haɗawa da ingantattun tashoshi masu kyau da mara kyau a cikin batirin lithium ion na yau da kullun ya ƙunshi potassium hydroxide ko lithium hydroxide, wanda ke amsawa da graphite a cikin ingantaccen lantarki yayin caji.

Wani sinadari na batirin lithium ion mai amfani shine graphite, wanda ta hanyar sinadarai tare da electrolyte yana samar da wani tauri mai ƙarfi da ake kira carbon dioxide pentoxide, wanda ke aiki azaman insulator. A cikin baturi na lithium polymer, duk da haka, electrolyte ya ƙunshi poly (ethylene oxide) da poly (vinylidene fluoride), don haka babu buƙatar graphite ko wani nau'i na carbon. Polymers sune kayan da suke manyan kwayoyin halitta, waɗanda zasu iya tsayayya da yanayin zafi da wasu lalata.

Polymers da aka yi amfani da su a cikin batirin lithium polymer suna ba da kayan da ke haɓaka daidaiton gel-kamar idan aka kwatanta da sauran nau'ikan baturan lithium ion. Electrolyte ya ƙunshi kaushi na halitta wanda za'a iya kera shi ba tare da lithium ba, don haka ya zama nau'in baturi mafi tsada.

Ana amfani da batirin lithium polymer a aikace-aikace da yawa saboda suna da sassauƙa kuma suna iya jure yanayin zafi fiye da sauran nau'ikan batirin lithium ion. Hakanan suna da nauyi fiye da waɗanda suka gabace su, wanda ke ba mai amfani damar riƙe na'urar tafi da gidanka tsawon lokaci ba tare da jin daɗi ko jin zafi a wuyan hannu da hannayensu ba.
