Uvavanyo lokwaluphala lwenza inani elikhulu lemijikelo yokutshaja kunye nokukhupha ibhetri ukuvavanya ubomi bomjikelo webhetri. Ngokwesiqhelo, ibhetri ithathwa njengefikelele esiphelweni sobomi bayo bomjikelo xa amandla ayo ewohloka ukuya kwipesenti ethile yomthamo wayo wokuqala (umz., 80%).
3. Ukwanda kokumelana kwangaphakathi: Ukumelana kwangaphakathi luphawu olubalulekileyo lwebhetri, oluchaphazela ngokuthe ngqo ukusebenza kakuhle kokutshaja kunye nokukhupha ibhetri kunye nokusebenza kakuhle kokuguqula amandla. Olu vavanyo lokwaluphala luvavanya ukwanda kokumelana kwangaphakathi kwebhetri ngokulinganisa utshintsho kukumelana kwangaphakathi kwebhetri ngexesha lokutshaja kunye nokukhupha ibhetri.
4. Ukusebenza kokhuseleko: Olu vavanyo lokwaluphala lukwabandakanya uvavanyo lokusebenza kokhuseleko lwebhetri. Oku kunokubandakanya ukulinganisa indlela esebenza ngayo ibhetri phantsi kweemeko ezingaqhelekanga ezifana nobushushu obuphezulu, ukutshaja kakhulu, kunye nokukhupha kakhulu ukuze kubonwe ukhuseleko kunye nokuzinza kwebhetri phantsi kwezi meko.

Kutheni ukumelana kwangaphakathi kwebhetri kusanda emva kokusetyenziswa ixesha elithile? Iza kuba yintoni impembelelo?
Emva kokuba ibhetri isetyenzisiwe ixesha elide, ukumelana kwangaphakathi kuyakhula ngenxa yokuguga kwezinto zebhetri kunye nolwakhiwo lwayo. Ukumelana kwangaphakathi kukuxhathisa okufumaneka xa umbane udlula kwibhetri. Kumiselwa ziimpawu ezintsonkothileyo zendlela yangaphakathi yokuqhuba ibhetri eyenziwe zii-electrolytes, izinto ze-electrode, abaqokeleli bamandla ombane, ii-electrolytes, njl. Oku kulandelayo yimpembelelo yokumelana kwangaphakathi okwandisiweyo ekusebenzeni kakuhle kokukhupha:
1. Ukwehla kweVolthi: Ukumelana kwangaphakathi kuya kubangela ukuba ibhetri ivelise ukwehla kweVolthi ngexesha lenkqubo yokukhupha. Oku kuthetha ukuba iVolthi yokwenyani iya kuba ngaphantsi kweVolthi yeSekethe evulekileyo yebhetri, ngaloo ndlela kunciphisa amandla akhoyo ebhetri.
2. Ukulahleka kwamandla: Ukumelana kwangaphakathi kuya kubangela ukuba ibhetri ivelise ubushushu obongezelelekileyo ngexesha lokukhupha, kwaye obu bushushu bumele ukulahleka kwamandla. Ukulahleka kwamandla kunciphisa ukusebenza kakuhle kokuguqulwa kwamandla ebhetri, nto leyo ebangela ukuba ibhetri inike amandla angasebenzi kakuhle phantsi kweemeko ezifanayo zokukhupha.
3. Ukwehla kwamandla ombane: Ngenxa yokwanda kokumelana kwangaphakathi, ibhetri iya kuba nokwehla okukhulu kwamandla ombane kunye nokulahleka kwamandla xa ikhupha amandla aphezulu, nto leyo eya kubangela ukuba ibhetri ingakwazi ukubonelela ngamandla aphezulu. Ke ngoko, ukusebenza kakuhle kokukhupha amandla kuyancipha kwaye amandla okukhupha amandla ebhetri ayancipha.
Ngamafutshane, ukwanda kokuxhathisa kwangaphakathi kuya kubangela ukuba ukusebenza kakuhle kokukhupha ibhetri kwehla, nto leyo echaphazela amandla akhoyo ebhetri, amandla aphumayo, kunye nokusebenza ngokubanzi. Ke ngoko, ukunciphisa ukumelana kwangaphakathi kwebhetri kunokuphucula ukusebenza kakuhle kokukhupha ibhetri kunye nokusebenza kwayo.
