Abin farin ciki, sakamakon aikin da na yi a baya, na cire ɗaruruwan batura a hannuna, waɗanda suka haɗa da batirin ƙarfe phosphate na lithium-ion, batir lithium na terpolymer, batura masu sassauƙa da batura masu siliki. A yau zan watse in nuna muku halin da ke ciki panel na baturi.

Yayin da ions lithium suka shiga, graphite anode a hankali ya zama zinare, amma yana da wahala a ga anode ta canjin launi. Yawancin lokaci muna yin hukunci akan tsarin caji da caji da ingancin baturin ta hanyar tarwatsa baturin da lura da yanayin mu’amalar wutar lantarki mara kyau.

SOC = 7%, akwai barbashi a tsakiyar wutar lantarki, kuma wutar lantarki ba ta canza launi ba.

Lokacin SOC = 14%, ana iya ganin barbashi a tsakiyar lantarki. Dan kadan canza launi.

SOC shine 26% ɗan ƙaramin shuɗi.

SOC = 53.9%, ya juya shuɗi, ana iya ganin kumfa.

Matsayin caji = 70.0%, daga shunayya mai duhu zuwa ja, baƙar fata mara caji a bayyane. Ba a sami hazo lithium ion ba.

Cikakken caji = 81.5%, yana juya zuwa zinari, yanki mai baƙar fata da ba a caji. Kuna iya ganin juyin halittar farin lithium.

Kamar yadda ake iya gani daga adadi na sama, lokacin da cajin da aka caji bai wuce 50% ba, yanayin lantarki ba ya canzawa da yawa. Ana iya lura da canje-canje a cikin lantarki sama da 50%. Kamar yadda aka nuna a hoto na 4, ana iya samun adadi mai yawa na kumfa a kusa da 3.6V. Ana iya fahimtar cewa akwai gagarumin canji tsakanin Hoto na 5 da Hoto na 6. Jihar da ake cajin tana canzawa da kashi 10 kawai, amma yanayin wutar lantarki ya bambanta.

Yanayin Electrode lokacin da baturi SOC = 100%. Bangaren fari shine lithium.

Bayan cire ɓangaren farin, saman ƙananan sandar ba ya juya zinariya, yana nuna cewa ions lithium ba a saka su a cikin kayan lantarki mai kyau ba. A takaice dai, ingantaccen abu a cikin wannan ɓangaren kayan yana hana lithium ions daga haɗawa, don haka ions lithium suna hazo zuwa saman. Ana hasashe cewa masu ɗaure (CMC da SBR) an rarraba su ba daidai ba a kan saman lantarki kuma an shafe su da carbon a cikin kayan anode, wanda ke haifar da shigar da lithium ion.

Lokacin da jihar da aka caje ta kasance 100%, yawancin wuraren baƙaƙen wuraren da ba a caji. Akwai baƙar fata da yawa akan baturin, wanda shine muhimmin dalili na ƙarancin ƙarfin baturin. Mahimman abubuwan da ke haifar da baƙar fata sune daidaitattun slurry, daidaitaccen iko mai yawa na rufin rufin, kula da tashin hankali na iska da samuwar gas.
