国BAE蓄电池充电过程和放电过程互为逆反应。可逆过程就是热力学的平衡过程,为保障电池能够始终维持在平衡状态之下充电,必须尽量使通过电池的电流小一些。理想条件是外加电压等于电池本身的电动势。但是,实践表明,蓄电池充电时,外加电压必须增大到一定数值才行,而这个数值又因为电极材料,溶液浓度等各种因素的差别而在不同程度上超过了蓄电池的平衡电动势值。在化学反应中,这种电动势超过热力学平衡值的现象,就是极化现象。
欧姆极化充电过程中,德国BAE蓄电池正负离子向两极迁移。在离子迁移过程中不可避免地受到一定的阻力,称为欧姆内阻。为了克服这个内阻,外加电压就必须额外施加一定的电压,以克服阻力推动离子迁移。该电压以热的方式转化给环境,出现所谓的欧姆极化。随着充电电流急剧加大,欧姆极化将造成蓄电池在充电过程中的高温。
德国BAE蓄电池浓度极化电流流过蓄电池时,为维持正常的反应,***理想的情况是电极表面的反应物能及时得到补充,生成物能及时离去。实际上,生成物和反应物的扩散速度远远比不上化学反应速度,从而造成极板附近电解质溶液浓度发生变化。也就是说,从电极表面到中部溶液,电解液浓度分布不均匀。这种现象称为浓度极化。
德国BAE蓄电池电化学极化这种极化是由于电极上进行的电化学反应的速度,德国BAE蓄电池落后于电极上电子运动的速度造成的。例如:电池的负极放电前,电极表面带有负电荷,其附近溶液带有正电荷,两者处于平衡状态。放电时,立即有电子释放给外电路。电极表面负电荷减少,而金属溶解的氧化反应进行缓慢Me-eMe+,德国BAE蓄电池不能及时补充电极表面电子的减少,电极表面带电状态发生变化。这种表面负电荷减少的状态促进金属中电子离开电极,金属离子Me+转入溶液,加速Me-eMe+反应进行。总有一个时刻,达到新的动态平衡。
