Lefapheng la electrochemistry, katleho le ts'ebetso ea lisele tsa electrochemical li bohlokoa haholo. Har'a likarolo tse fapaneng tse tlatsetsang katlehong, li-anode tse emeng li bapala karolo ea bohlokoa. Li-electrode tsena tse emeng ha li felle feela ka likarolo tse sa sebetseng; ke mokokotlo oa tsamaiso ea electrochemical, e susumetsang kakaretso ea karabelo kinetics, botsitso le bophelo bohle ba sele.
Li-anode tse emengli etselitsoe hore li lule li le boemong bo tsitsitseng nakong ea ts'ebetso ea electrochemical, ho fana ka sethala se tsitsitseng bakeng sa liketso tsa oxidation tse hlahang ho anode. Botsitso bona bo bohlokoa bakeng sa ho boloka ts'ebetso e tsitsitseng ka nako. Ho fapana le li-anode tse tsamaeang kapa tse potolohang, li-anode tse emeng li felisa mathata a amanang le motsamao oa mochini, ho etsa hore moralo le ts'ebetso ea lisele tsa electrochemical li be bonolo.
E 'ngoe ea melemo ea mantlha ea li-anode tse emeng ke bokhoni ba tsona ba ho eketsa katleho ea karabelo ea electrochemical. Ka ho fana ka sebaka se tsitsitseng bakeng sa phetisetso ea elektronike, li-anode tse emeng li khothalletsa oxidation ea li-reactants, ka tsela eo li eketsa bongata ba hona joale le ho ntlafatsa ts'ebetso ea lisele ka kakaretso. Sena se bohlokoa haholo lits'ebetsong tse kang electrolysis, lisele tsa mafura, le libeteri, moo ho ntlafatsa ts'ebetso ea li-electrochemical reaction ho ka amang tlhahiso ea matla le litšenyehelo tsa ts'ebetso haholo.
Ntle le moo, li-anode tse emeng li ka etsoa ho sebelisoa lisebelisoa tse fapaneng ho ntlafatsa ts'ebetso ea tsona. Lisebelisoa tse tloaelehileng li kenyelletsa graphite, platinum, le li-oxide tse fapaneng tsa tšepe, tseo e 'ngoe le e' ngoe e nang le thepa e ikhethang e ka ntlafatsang karabelo ea electrochemical. Ka mohlala, li-anode tsa graphite li tsejoa ka mokhoa o babatsehang oa ho khanna le botsitso ba lik'hemik'hale, tse etsang hore e be tse loketseng bakeng sa mefuta e mengata ea likopo. Ka lehlakoreng le leng, li-anode tsa platinum li atisa ho sebelisoa liseleng tsa mafura tse sebetsang hantle ka lebaka la thepa ea tsona e babatsehang ea ho thusa.
Moralo oa anode e emeng le ona o bapala karolo ea bohlokoa ts'ebetsong ea ona. Lintho tse kang sebaka sa holim'a metsi, porosity, le morphology li ka ama ts'ebetso ea electrochemical haholo. Sebaka se seholoanyane se lumella libaka tse sebetsang haholoanyane ho itšoara, ha mohaho o nang le porous o ka ntlafatsa lipalangoang tsa thepa, ho netefatsa hore li-reactants li fihla ho anode ka katleho. Bafuputsi ba lula ba hlahloba meralo le lisebelisoa tse ncha ho ntlafatsa ts'ebetso ea li-anode tse emeng le ho sutumelletsa meeli ea theknoloji ea electrochemical.
Ntle le ho ntlafatsa ts'ebetso, li-anode tse emeng li thusa ho lelefatsa bophelo ba lisele tsa electrochemical le ho ntlafatsa botsitso ba lisele. Ka ho fana ka sethala se tsitsitseng le se ka tšeptjoang bakeng sa karabelo, ba thusa ho fokotsa litaba tse kang ho senyeha ha li-electrode le passivation, tse ka etsang hore ts'ebetso e theohe ha nako e ntse e ea. Botsitso bona bo bohlokoa ka ho khetheha lits'ebetsong tsa indasteri, moo litšenyehelo tsa nako le tlhokomelo li leng holimo.
Ha tlhoko ea litharollo tsa matla tse sebetsang hantle e ntse e hola, bohlokoa ba li-anode tse emeng liseleng tsa electrochemical bo ke ke ba nyenyefatsoa. Bokhoni ba bona ba ho eketsa katleho ea karabelo, ho ntlafatsa botsitso, le ho lelefatsa bophelo ba litsamaiso tsa electrochemical li ba etsa karolo ea bohlokoa ntlafatsong ea mahlale a tsoetseng pele a matla. Ho tloha ho matla a ka nchafatsoang ho isa litharollong tsa polokelo ea matla, li-anode tse emeng li bula tsela bakeng sa bokamoso bo tsitsitseng le bo sebetsang haholoanyane.
Ka kakaretso,li-anode tse emengehlile ke mokokotlo oa lisele tse sebetsang hantle tsa electrochemical. Moqapi oa bona, khetho ea thepa, le botsitso ba ts'ebetso ke lintlha tsa bohlokoa tse susumetsang ts'ebetso ea mefuta e mengata ea lisebelisoa tsa electrochemical. Ha lipatlisiso le nts'etsopele lefapheng lena li ntse li tsoela pele, re ka lebella ho bona litharollo tse ncha tse eketsang thepa e ikhethang ea li-anode tse emeng, ho nts'etsapele theknoloji ea electrochemical le ts'ebeliso ea eona bophelong ba rona ba letsatsi le letsatsi.
