Hour rate rated capacity corresponding current.
Battery is when electric current flows through, and both positive and negative polarity is chemically reacting, and the consumption of reactant causes positive/negative plate table
Concentration in face and neighbouring ion concentration and original solution is somewhat different, and thus the phenomenon of caused potential difference turns into concentration polarization
Change.Concentration polarization greatly hinders the charging of battery.
In formation process, forming current is an important technological parameter.The size of forming current is for formation efficiency, change
Chemical conversion quality into cost and pole plate has large effect.If forming current is bigger than normal, polarization of electrode can be caused to increase
Greatly, voltage rises too high, and gas evolution is too fast, and being on the one hand likely to result in plate active material becomes loose or come off, another
Aspect can reduce current efficiency, increase power consumption, meanwhile, the temperature rise of electrolyte can also accelerate.When forming current is less than normal, electric current
Density is reduced, formation charging not enough power supply, and pole plate chemical conversion can be caused insufficient.
