Karkashin Batari da Fitowa batari

A cikin bayanin wannan batu na iya kadan daidai, ma'ana karkashin da kuma kawo shi , zan iya haka da fahimta game da maimaita da kuma sauyin kima. Saboda, batiri suna karkashin da kuma kawo shi saboda maimaita da kuma sauyin kima.
Don fahimta masana maimaita da kuma sauyin kima, zan iya tuka zuwa misal mai kimiyya. Za a duba kimiyyar zink da klorin.

A cikin wannan kimiyya, zink (Zn) ya kawo duwatsu da suka biyo waɗanda suka zama ions gaba-gaba.

A nan, klorin yana ɗauke da wata electrons kuma zama ions gaba-gaba.

Tana, waɗannan ions gaba-gaba da ke ɗaya suka zama zink chloride (ZnCl2)
A cikin wannan kimiyya, saboda zink ya kawo electrons, an yi maimaita kuma klorin ya ɗauke da electrons, saboda haka an yi sauyin kima.
Idan atom ya kawo electrons, lambar tsarin maimaitar ta ya faru. A nan, a cikin misalna, lambar tsarin maimaitar zink ya zama + 2 daga 0. Saboda lambar tsarin maimaita ya faru, wannan ƙarshen kimiyya ana kiranta maimaita. Amma, idan atom ya ɗauke da electrons, lambar tsarin maimaitar ta ya faru, wato lambar tsarin maimaitar ta ya ci gaba. Saboda lambar tsarin maimaita ya ci gaba ko sauye, wannan ƙarshen kimiyya ana kiranta sauyin kima.

Kawon Batiri

A cikin batiri, akwai duhu electrodes da aka ɗaukan kan electrolyte. Idan mutane da ke ɗaya suka ɗaukar waɗannan duhu electrodes, maimaitar kimiyya tana bari a cikin ɗaya da electrodes, kuma a nan sauyin kimiyya tana bari a cikin ɗaya da electrodes.
Electrode, inda maimaitar kimiyya tana bari, yawan electrons tana fiye. Wannan electrode ana kiranta electrode gaba-gaba ko anode.

Amma, a nan a lokacin kawon batiri, ɗaya da electrodes tana ɗauke da sauyin kimiyya. Wannan electrode ana kiranta cathode. Electrons da suka fiye a anode, tana ƙare a cathode karkashin mutane da ke ɗaya. A cikin cathode, waɗannan electrons suka ɗauke, wato material da ke cathode tana ɗauke da sauyin kimiyya.
Tana, ma'adatar maimaitar kimiyya a anode suna ions gaba-gaba ko cations, wanda za su ƙare a cathode karkashin electrolyte, kuma a nan, ma'adatar sauyin kimiyya a cathode suna ions gaba-gaba ko anions, wanda za su ƙare a anode karkashin electrolyte.
Za a duba misal na amfani don bayyana kawon batiri. Za a duba batiri na nickel cadmium. A nan, cadmium tana anode ko electrode gaba-gaba. A lokacin maimaitar a anode, cadmium metal tana ɗauke da OH – ion kuma ya kawo duwatsu da suka biyo waɗanda suka zama cadmium hydroxide.

Cathode na batirin tana jin nickel oxyhydroxide ko haserensu nickel oxide. A cikin cathode, sauyin kimiyya tana bari, saboda haka, nickel oxyhydroxide tana zama nickel hydroxide ta ɗauke da electrons.

Karkashin Batiri

A lokacin karkashin batiri, an yi ɗaukar DC source a kan batiri. An ɗaukar terminal gaba-gaba na DC source a kan plate gaba-gaba ko anode na batiri, kuma an ɗaukar terminal gaba-gaba na source a kan plate gaba-gaba ko cathode na batiri.

A nan, saboda DC source na kan ɗaya, electrons za su ƙare a anode. Sauyin kimiyya tana bari a anode, ba a cathode. Idan a lokacin kawon batiri, sauyin kimiyya tana bari a cathode. Saboda hakan, material na anode tana ɗauke da electrons kuma tana ƙara a matsayin da ta zama a lokacin da batiri ba ta kawo shi.
Saboda terminal gaba-gaba na DC source tana ɗauka a kan cathode, electrons na kan ɗaya tana ƙare a kan terminal gaba-gaba na DC source. Saboda haka, maimaitar kimiyya tana bari a cikin cathode, kuma material na cathode tana ƙara a matsayin da ta zama a lokacin da batiri ba ta kawo shi. Wannan tana cikin ƙarfin karkashin batiri.

A nan za a duba misal na batiri na rechargeable nickel cadmium. A lokacin karkashin batiri, terminal gaba-gaba da terminal gaba-gaba na charger DC source tana ɗauka a kan terminal gaba-gaba da terminal gaba-gaba na batiri. A cikin anode, saboda presence electrons na kan terminal gaba-gaba na DC, sauyn kimiyya tana bari, saboda haka, cadmium hydroxide tana zama cadmium rawa kuma ya kawo hydroxide ions (OH–) a kan electrolyte.

A cikin cathode ko terminal gaba-gaba, saboda maimaitar kimiyya, nickel hydroxide tana zama, nickel oxyhydroxide ta kawo ruwa a kan electrolyte solution.

A lokacin karkashin batiri, batiri na secondary tana ƙara a matsayin da ta zama a lokacin da ta karkasha, kuma tana ɗaya don kawo shi a lokacin da batiri ba ta kawo shi.
