A taƙaice, ana cajin ƙarfin wutar lantarki na baturin lithium-ion sama da iyakar B (4.20V) ya wuce kima. Amma yawan cajin kuma matakin girma ne.

Matsakaicin mutum yana tunanin ƙasa da 4.24V, ƙila ba zai yi girma ba. Ko kuma "zai iya The micro-charge.

Ƙayyadaddun baturi na mai kera batirin lithium-ion shima yana nuna cewa ƙarfin cajin iyaka shine 4.20V +/- 0.04V.

Tsakanin iyaka A da iyakar B (mafi girma fiye da 4.24V, ƙasa da 4.35) V) Ana iya kiran wannan yanki matsakaici don caji.

Batirin lithium ion a cikin wannan kewayon ƙarfin lantarki, ƙarfin fitarwa zai kasance sama da batirin lithium ion na yau da kullun. Da fatan za a duba matsakaici fiye da caji da gwaji na bayanai shine baturi: GY383450. Matsakaicin iyaka: 550mAh.

Nau&39;in caja iyaka ƙarfin lantarki 4.20V tsarin caji: Wutar lantarki yana ƙasa da cajin iyakataccen matsa lamba, bayan ƙarfin lantarki ya kai iyakar ƙarfin caji, ƙarfin kulawa bai canza ba, sannu a hankali na yanzu yana raguwa zuwa 20 mA Cajin ƙarshe. Wannan yanayin cajin CC/CV ne na al&39;ada.

Tsarin fitarwa: 1C (550mA), ƙaddamarwar ƙarfin lantarki 2.75V tsarin an cika shi zuwa aiwatar da daidaitattun ƙasa. Za mu iya ƙoƙarin canza ƙarfin wutar lantarki mai iyaka na caji, da gangan Samfurin gwaji ya cika caji.

Jera siffofin gwaji kamar haka: Ƙarfin cajin keken keke iyaka ƙarfin ƙarfin cajin V na caji MAH ƙarfin fitarwa MAH da ƙimar iya aiki% na farkon 4.204565 Wannan shine ƙimar ƙarfin na biyu 4.204818% na uku 4.

20V569564100 % Lokaci na hudu 4.35V633627112% shine don kwatantawa, yana nuna cewa ƙarfin baturin yana da ɗan bambanci bayan an yi masa caji. Daga gare ta na iya samun ƙarewa, ƙarin caji na iya ƙara ƙarfin baturi.

Amma wannan yanayin Ba iri ɗaya bane, lokacin da na ci gaba da yin cajin wannan baturin lithium ion tare da iyakar cajin 4.35V. Ƙarshen ba shi da kyakkyawan fata.

Bayan 50th, ƙarfin baturi shine 480mAh. Ya riga ya zama kashi 85% na iya aiki. Kuma lokacin da na gudanar da zagaye na yau da kullun na wannan ƙirar a baya, ƙarfina har yanzu ya fi 88% na ƙimar da aka ƙididdigewa a zagayowar 150.

Ana iya ganin cewa rayuwar batir ta cika da yawa. Bugu da ƙari da aka ambata Ee, baturin da aka yi cajin ya kasance ɗan ƙaramin ganga, kauri na asali shine 3.84mm, kauri kuma shine 4.

25mm bayan 50 hawan keke. Tunda ƙarfin lantarkin da ke sama da 4.35V bai isa ba ta batirin lithium-ion mai alaƙa da layin kariya Duk manyan masu amfani galibi suna fuskantar wannan sabon abu.

Yawancin cajin kwai marasa cancanta (sau da yawa ana samun sama da nickel-hydrogen da kayan lithium-ion gear ana iya zaɓar) mai laifi. Su Don haka sama da 4.35V Menene kamanni? Ina yin gwajin aminci.

Shi ne don cire layin kariya na baturin, sa&39;an nan kuma cajin baturin lithium-ion tare da ƙarfin lantarki na 5.0V. Sakamakon shine sa&39;o&39;i 3 ~ 4 A nan gaba, baturin yana da ƙarfi sosai, kuma wasu sel marasa cancanta sun fashe.

Ƙarƙashin microscopy na lantarki, bayanan lantarki na lithium yana da rufi sosai, kuma ingantaccen lantarki shine wasu kusurwoyi da aka tattara, kuma siffar ta bambanta dangane da kayan anode. Matsakaicin juyin halittar fiye da kima yana faruwa ne sakamakon rugujewar faranti mara kyau. Lokacin caji, lamba da saukakawa na lithium ions a cikin farantin lantarki mara kyau yana iyakance.

Capacity ya ragu, sabon juriya na ciki, gajeriyar rayuwa ba a dawo da ita ba. Mafi muni! Baturin ya kai cikakken yanayi. Ana sanya martanin shigar da na&39;urar da ba ta da kyau a cikin jigilar lithium karfe a saman wutar lantarki mara kyau, kuma adadin zafin da ke haifar da kaushi da ke haifar da wuce gona da iri yana da yawa sama da na zafin lithium ion da sauran ƙarfi a cikin yanayin mai jujjuyawa): Haɓakar zafin baturi, ƙarfe lithium da sauran ƙarfi, halayen lithium, carbon da sauran ƙarfi a cikin wuta.

Tare da nazarin electrolyte, tanguger da ƙarfe na lithium kuma zasu iya amsawa. Bayan cajin, saman a kan farantin karfe ne crystallization na lithium mai siffar allura, kuma diaphragm zai faru. Mask, matsanancin zubar da kai; nauyi kristal gajeriyar da&39;ira halin yanzu ya haifar da zafin baturi cikin sauri, electrolyte bincike gasification.

Wannan halin da ake ciki, ko zafin jiki ya yi yawa don sa kayan ƙonewa ya fashe. Ko kuma harsashi ya fara fara daukar hankali, ta yadda iskar da aka zuba a ciki da kuma karafa na lithium, wadanda dukkansu aka jefa bam a cikin fashewar konewa.
