Muva nje, kutholakale ukuthi izinga lokushisa lehle kakhulu, futhi ibhethri ligcwele ngemuva kokushajwa, kodwa laphelelwa amandla ngemuva kokulisebenzisa. Kulokhu, ake sikhulume ngobudlelwano phakathi kwebhethri nezinga lokushisa:
If amabhethri e-lithium asetshenziswa ezindaweni zokushisa eziphansi, okungukuthi, ngaphansi kuka-4℃, isikhathi sesevisi yebhethri sizoncishiswa, futhi amanye amabhethri e-lithium yasekuqaleni awakwazi ngisho nokushajwa ezindaweni zokushisa eziphansi. Kodwa ungakhathazeki kakhulu. Lesi yisimo sesikhashana nje, esihlukile ekusetshenzisweni endaweni yokushisa ephezulu. Uma izinga lokushisa likhuphuka, ama-molecule ebhethri azofudunyezwa, futhi ibhethri lizothola amandla alo angaphambilini ngokushesha. Uma izinga lokushisa liphakeme, izinga lokunyakaza kwe-anion kanye ne-cation lishesha kuseli eliyinhloko, izinga lokuzuza nokulahlekelwa kwama-electron kuma-electrode amabili liyashesha, futhi kuba likhulu kwamanje.
Umthelela Wezinga Lokushisa Ekumelaneni Kwangaphakathi Kwebhethri Esimeni SokuthiIsikali SamaloliUbunjiniyela
Lapho ikhipha ekushiseni kwe-ambient engu-0℃~30℃, ukumelana kwangaphakathi kwebhethri kuncipha ngokunyuka kwezinga lokushisa. Ngokuphambene nalokho, lapho izinga lokushisa lebhethri lincipha, ukumelana kwangaphakathi kwebhethri kuyanda kancane kancane, futhi ukumelana kwangaphakathi kwebhethri kushintsha ngokuhambisana nezinga lokushisa Ngakho-ke, izinga lokushisa elisebenzayo lokukhishwa kwebhethri lingaphakathi kwebanga elingu-0.℃~30℃. I-conductivity ye-electrolyte yinhle, futhi isivinini sokusabalalisa se-hydrogen ion ne-sulfate ion ku-electrolyte kuya entweni esebenzayo nalo liphezulu. Lokhu akugcini nje ukuthuthukisa umphumela we-polarization wokuhlushwa, kodwa futhi kuthuthukisa isivinini sokuphendula kwe-electrode, kuthuthukise umthelela we-electrode.nici-chemical polarization, ngakho-ke amandla okukhipha ibhethri ayanda.
Lapho izinga lokushisa le-ambient lehla ngaphansi kuka-0℃, ukumelana kwangaphakathi kuzokwenyuka cishe ngo-15% kuzo zonke eziyi-10℃ukwehla kwezinga lokushisa. Ngenxa yokuthi i-viscosity yesisombululo se-sulfuric acid iba nkulu, ukumelana okukhethekile kwesisombululo se-sulfuric acid kuzokhula, okuzokwandisa umphumela we-electrode polarization. Umthamo webhethri uzokwehla kakhulu.
Umthelela weTi-emperature ivuliweCukuhlukumeza futhiDiyashaja
Phinda umjikelezo wokushajwa kanye nokushajwa kwamandla kagesi aphansi. Esigabeni sokuqala, izinga lokushisa lebhethri aliphezulu ngenxa yokuqhutshwa kokushisa. Uma umjikelezo wokushaja nokukhipha uphinda, izinga lokushisa le-electrolyte lizoba phezulu kakhulu.
Uma ishaja ngezinga lokushisa eliphansi, ukuminyana kwamanje kwe-diffusion kuncipha kakhulu, kuyilapho ukuminyana kwamanje kokushintshisana kuncipha kakhulu, ngakho-ke i-concentration polarization iyaqina, okuzoholela ekwehliseni ukusebenza kahle kokushaja Ngakolunye uhlangothi, ukugcwala kwe-lead sulfate yokugcina ekhishwe. ezingeni lokushisa eliphansi kwandisa ukumelana nokushajwa kwebhethri nokusabela kokushajwa, ngaleyo ndlela kunciphise nakakhulu ukusebenza kahle kokushaja.
Uma ibhethri lishajwe ezingeni lokushisa elingaphezu kuka-10℃, i-polarization iyancipha kakhulu, futhi izinga lokuqedwa kanye ne-solubility ye-lead sulfate ingathuthukiswa. Ngaphezu kwalokho, izinga lokusabalalisa komoyampilo liyakhuphuka ngezinga lokushisa eliphezulu, okuzothuthukisa ukushajwa kwebhethri nokusebenza kahle kokushajwa ngaphansi kwethonya lalezi zici ezibanzi.
