Kungekudala, kwafunyaniswa ukuba ukushisa kwehle ngokukhawuleza, kwaye ibhetri yayigcwele emva kokutshaja, kodwa yaphela amandla emva kokusetyenziswa. Kule meko, makhe sithethe ngobudlelwane phakathi kwebhetri kunye nobushushu:
If iibhetri ze-lithium zisetyenziswa kwiindawo eziphantsi kweqondo lokushisa, oko kukuthi, ngaphantsi kwe-4℃, ixesha lenkonzo yebhetri liya kuncitshiswa, kwaye ezinye iibhetri ze-lithium zangaphambili azikwazi nokuhlawuliswa kwiindawo eziphantsi zokushisa. Kodwa ungakhathazeki kakhulu. Le yimeko nje yesikhashana, eyahlukileyo ekusebenziseni kwindawo yokushisa okuphezulu. Nje ukuba iqondo lobushushu linyuke, iimolekyuli ezikwibhetri ziya kufudunyezwa, kwaye ibhetri iya kubuyisela amandla ayo angaphambili ngoko nangoko. Ukuphakama kweqondo lokushisa, ngokukhawuleza isantya sokuhamba kwe-anion kunye ne-cation kwiseli yokuqala, ngokukhawuleza izinga lokuzuza kwe-electron kunye nokulahlekelwa kwi-electrode ezimbini, kwaye inkulu ngoku.
Impembelelo yoBubushushu kuMchaso waNgaphakathi webhetri kwimeko yeIsikali seloriUbunjineli
Xa ukhupha kwiqondo lobushushu le-ambient ye-0℃~30℃, ukuchasana kwangaphakathi kwebhetri kunciphisa ngokunyuka kweqondo lokushisa. Ngokuchasene noko, xa ubushushu bebhetri buhla, ukuchasana kwangaphakathi kwebhetri kuyanda ngokuthe ngcembe, kwaye ukuchasana kwangaphakathi kwebhetri kutshintsha ngokuhambelana nobushushu, Ke ngoko, ubushushu bokusebenza bokukhutshwa kwebhetri buphakathi koluhlu lwe-0.℃~30℃. I-conductivity ye-electrolyte ilungile, kwaye isantya sokusasazwa kwe-ion ye-hydrogen kunye ne-ion ye-sulfate kwi-electrolyte ukuya kwinto esebenzayo nayo iphezulu. Oku akuphuculi kuphela umphumo we-polarization yoxinaniso, kodwa kuphucula isantya sokuphendula i-electrode, ukuphucula ngakumbi impembelelo ye-electro.nici-chemical polarization, ngoko amandla okukhutshwa kwebhetri ayanda.
Xa ubushushu be-ambient buhla ngaphantsi kwe-0℃, ukuchasana kwangaphakathi kuya kunyuka malunga ne-15% kwi-10 nganye℃ukwehla kobushushu. Ngenxa yokuba i-viscosity yesisombululo se-sulfuric acid iba nkulu, ukuchasana okukodwa kwesisombululo se-sulfuric acid kuya kwanda, okuya kwandisa umphumo we-electrode polarization. Umthamo webhetri uya kuncipha kakhulu.
Impembelelo yeTi-emperature ivuliweCukuhlamba kunyeDiyatshaja
Phinda umjikelo wokukhutshwa kunye ne-low-voltage rhoqo ukutshaja umbane. Kwinqanaba lokuqala, ubushushu bebhetri abukho phezulu ngenxa yokuqhuba ubushushu. Ukuba umjikelo wokutshaja kunye nokukhutshwa uphindwe, ubushushu be-electrolyte buya kuba phezulu kakhulu.
Ukuba ukutshaja kwiqondo lokushisa eliphantsi, ukuxinana kwangoku kuncipha kakhulu, ngelixa ukutshintshiselana kwangoku kuncipha kakhulu, ngoko ke i-polarization yoxinaniso iyaqina, okuya kukhokelela ekunciphiseni ukusebenza kakuhle kokutshaja Ngakolunye uhlangothi, ukugcwala kwe-sulfate yokugqibela ekhutshiweyo. kwiqondo lobushushu elisezantsi kwandisa ukuxhathisa kokutshaja kwebhetri kunye nokuphendula kokukhupha, oko kunciphisa ngakumbi ukusebenza kakuhle kokutshaja.
Ukuba ibhetri itshajiwe kubushushu be-ambient obungaphezulu kwe-10℃, i-polarization iyancipha kakhulu, kwaye izinga lokuchithwa kunye ne-solubility ye-lead sulfate inokuphuculwa. Ukongeza, izinga lokusasazwa kwe-oxygen linyuka kwiqondo lokushisa eliphezulu, eliya kuphucula ukutshaja kwebhetri kunye nokukhupha ukusebenza kakuhle phantsi kweempembelelo zezi zinto zibanzi.
