Li-ion baturi ne mai ƙarancin kulawa, fa'idar da yawancin sauran sinadarai ba za su iya ɗauka ba.Baturin ba shi da ƙwaƙwalwar ajiya kuma baya buƙatar motsa jiki (cikakken fitarwa da gangan) don kiyaye shi cikin tsari mai kyau.Fitar da kai bai kai rabin na tsarin tushen nickel ba kuma wannan yana taimakawa aikace-aikacen ma'aunin man fetur.Wutar lantarki mai ƙima na 3.60V na iya ba da wutar lantarki kai tsaye wayoyin hannu, allunan da kyamarori na dijital, suna ba da sauƙaƙawa da ragi mai tsada akan ƙirar sel da yawa.Matsalolin shine buƙatar hanyoyin kariya don hana cin zarafi, da kuma farashi mai girma.
Asalin baturin lithium-ion na Sony yayi amfani da coke azaman anode (samfurin gawayi).Tun daga 1997, yawancin masana'antun Li ion, gami da Sony, sun canza zuwa graphite don samun lalurar fitarwa mai faɗi.Graphite wani nau'i ne na carbon wanda ke da kwanciyar hankali na tsawon lokaci kuma ana amfani dashi a cikin fensin gubar.Shi ne mafi yawan abubuwan carbon, wanda ke biye da carbons masu wuya da taushi.Nanotube carbons har yanzu ba su sami amfani da kasuwanci a cikin Li-ion ba saboda suna da alaƙa da haɗawa da tasiri.Wani abu na gaba wanda yayi alkawarin haɓaka aikin Li-ion shine graphene.
Hoto na 2 yana misalta yanayin fitar da wutar lantarki na Li-ion na zamani tare da graphite anode da farkon sigar coke.
An gwada wasu abubuwan ƙari da yawa, gami da galoli na tushen silicon, don haɓaka aikin graphite anode.Yana ɗaukar ƙwayoyin carbon (graphite) guda shida don ɗaure zuwa ion lithium guda ɗaya;zarra na silicon guda ɗaya na iya ɗaure ion lithium huɗu.Wannan yana nufin cewa silicon anode zai iya a ka'idar adana fiye da 10 makamashi na graphite, amma fadada da anode a lokacin caji ne matsala.Silicone anodes sabili da haka ba su da amfani kuma kawai kashi 3-5 na silicon yawanci ana ƙara su zuwa ga anode na tushen silicon don cimma rayuwa mai kyau.
Yin amfani da nano-tsarin lithium-titanate azaman ƙari na anode yana nuna rayuwa mai ban sha'awa, ƙarfin nauyi mai kyau, kyakkyawan aiki mai ƙarancin zafi da ingantaccen aminci, amma takamaiman makamashi yana da ƙasa kuma farashin yana da girma.
Gwaji tare da cathode da kayan anode suna ba masana'antun damar ƙarfafa halayen asali, amma haɓaka ɗaya na iya yin sulhu da wani.Abin da ake kira "Energy Cell" yana inganta takamaiman makamashi (ikon) don cimma tsawon lokaci mai tsawo amma a ƙananan ƙayyadaddun iko;"Power Cell" yana ba da takamaiman iko amma a ƙananan ƙarfin aiki.The "Hybrid Cell" wani sulhu ne kuma yana ba da kadan daga duka biyun.
Masu ƙera za su iya samun takamaiman ƙarfi da ƙarancin farashi cikin sauƙi ta ƙara nickel maimakon cobalt mafi tsada, amma wannan yana sa tantanin halitta ya ragu.Yayin da kamfani mai farawa zai iya mayar da hankali kan takamaiman makamashi da ƙarancin farashi don samun karbuwar kasuwa cikin sauri, aminci da dorewa ba za a iya yin lahani ba.Masu sana'a masu daraja suna sanya babban mutunci akan aminci da tsawon rai.
Yawancin batirin Li-ion suna raba irin wannan ƙira wanda ya ƙunshi na'ura mai ƙarfi na ƙarfe oxide tabbataccen lantarki (cathode) wanda aka lulluɓe akan mai tarawa na yanzu na aluminium, na'urar lantarki mara kyau (anode) wanda aka yi daga carbon / graphite mai rufi akan mai karɓar jan ƙarfe na yanzu, mai rabawa da electrolyte. wanda aka yi da gishirin lithium a cikin wani kaushi na halitta.Ƙarin bayani, pls ku tafi tare da teda baturi.com.
