Yadda ake inganta amincin batirin lithium

Amfanin sabbin motocin da ke amfani da makamashi shi ne cewa sun fi motocin da ke da iskar gas mai ƙarancin iskar gas da kuma kare muhalli.Yana amfani da makamashin motocin da ba na al'ada ba a matsayin tushen wutar lantarki, kamar batirin lithium, man hydrogen, da sauransu. Aiwatar da batirin lithium-ion shima yana da fadi sosai, baya ga sabbin motocin makamashi, wayoyin hannu, kwamfutar tafi-da-gidanka, PC na kwamfutar hannu, wutar lantarki, kekuna masu lantarki. , kayan aikin lantarki, da sauransu.

Koyaya, bai kamata a yi la'akari da amincin batirin lithium-ion ba.Hatsari da yawa sun nuna cewa lokacin da mutane suka yi cajin da bai dace ba, ko yanayin yanayin yanayi ya yi yawa, yana da sauƙi don haifar da konewar batirin lithium-ion ba tare da bata lokaci ba, fashewa, wanda ya zama wuri mafi girma a cikin ci gaban batirin lithium-ion.

Ko da yake kaddarorin batirin lithium da kansa yana ƙayyade makomarsa "mai ƙonewa da fashewa", amma ba shi yiwuwa gaba ɗaya rage haɗari da aminci.Tare da ci gaba da ci gaban fasahar batir, kamfanonin wayar salula da sabbin kamfanonin motocin makamashi, ta hanyar ingantaccen tsarin sarrafa batir da tsarin kula da zafi, baturin zai iya tabbatar da tsaro, kuma ba zai fashe ko tashin konewa ba.

1.Inganta lafiyar electrolyte

Akwai babban amsawa tsakanin electrolyte da duka biyu masu inganci da na'urorin lantarki, musamman a yanayin zafi.Don inganta amincin batura, inganta amincin electrolyte yana ɗaya daga cikin mafi inganci hanyoyin.Ta hanyar ƙara abubuwan da ke aiki, ta amfani da sabbin gishirin lithium da kuma amfani da sabbin kaushi, ana iya magance haɗarin aminci na electrolyte yadda ya kamata.

Dangane da ayyuka daban-daban na additives, ana iya raba su zuwa nau'ikan masu zuwa: abubuwan kariya na aminci, abubuwan da ke samar da fim, abubuwan kariya na cathode, abubuwan haɓaka gishirin lithium, abubuwan haɓaka haɓakar haɓakar lithium hazo, haɓakar haɓakar haɓakar ruwa mai tarawa, haɓaka haɓakar wettability additives. , da dai sauransu.

2. Inganta amincin kayan lantarki

Lithium iron phosphate da ternary composites ana daukar su a matsayin ƙananan farashi, "kyakkyawan aminci" kayan cathode waɗanda ke da yuwuwar yin amfani da su a masana'antar motocin lantarki.Don kayan cathode, hanyar da ake amfani da ita don inganta amincinta shine gyare-gyaren shafi, irin su ƙarfe oxides akan saman kayan cathode, na iya hana hulɗar kai tsaye tsakanin kayan cathode da electrolyte, hana canjin lokaci na kayan cathode, haɓaka tsarin sa. kwanciyar hankali, rage rikicewar cations a cikin lattice, don rage haɓakar zafi na gefe.

Kayan lantarki mara kyau, tun da yake samansa sau da yawa shine ɓangaren baturin lithium-ion wanda ya fi dacewa da lalatawar thermochemical da exotherm, inganta yanayin zafi na fim din SEI shine hanya mai mahimmanci don inganta lafiyar kayan lantarki mara kyau.Ana iya inganta kwanciyar hankali na thermal na kayan anode ta hanyar rashin isashshen iskar shaka, ƙarfe da ƙarfe oxide, polymer ko carbon cladding.

3. Inganta ƙirar kariyar aminci na baturi

Baya ga inganta amincin kayan batir, yawancin matakan kariya na kariya da ake amfani da su a cikin batura lithium-ion na kasuwanci, kamar saita batura na amincin baturi, fis ɗin da za su iya narkewa, haɗa abubuwan haɗin gwiwa tare da ingantattun ma'aunin zafin jiki a cikin jerin, ta amfani da diaphragms da aka rufe ta thermally, loda kariya ta musamman. da'irori, da keɓaɓɓun tsarin sarrafa baturi, suma suna nufin haɓaka aminci.
