            日月潭蓄電池在機房最佳適宜溫度

            發布時間:2019-10-29人氣:9

            日月潭蓄電池化學反應方程式可見,正極板上市PbO2,負極板上是Pb。這兩種物質的導電性能和物理性質都隨溫度變化極小,因此,可以說,日月潭 蓄電池放電性能的溫度效應是由于硫酸所致,因為只有它的活化性能(離解程度和離子遷移速度)與溫度相關。

            日月潭 蓄電池硫酸電解液的溫度高,容量輸出就多,電解液的溫度低,容量輸出就少。照成這種情況的原因,除由于溫度降低之外,還由于溫度降低時,硫酸鉛在硫酸電解液中的溶解度也將降低,這必然使極板周圍的鉛離子造成飽和,迫使形成的硫酸鉛結晶致密,這個致密的結晶阻礙了活性物質與硫酸電解液的充分接觸,從而使日月潭 蓄電池容量輸出減少。

            日月潭 蓄電池在放電時如果硫酸電解液溫度較高,這就會使極板表面的PbSO4在硫酸電解液中的過飽和度降低,而有利于形成疏松的硫酸鉛結晶,使之在充電時生產粗大堅固的PbO2層,從而可延長極板活性物質的使用壽命。日月潭 蓄電池在充電時如果電解液的溫度過高,則會使電解液的擴散加快,極板板柵的腐蝕加劇,從而也就使日月潭 電池的使用壽命縮短。日月潭蓄電池官網

            From the chemical reaction equation of Riyuetan battery, it can be seen that PbO2 is on the positive plate and Pb is on the negative plate. The conductivity and physical properties of these two substances have little change with temperature. Therefore, it can be said that the temperature effect of discharge performance of Riyuetan battery is caused by sulfuric acid, because only its activation performance (dissociation degree and ion migration speed) is related to temperature.

            The temperature of sulfuric acid electrolyte of Riyuetan battery is high, the capacity output is more, the temperature of electrolyte is low, the capacity output is less. The reason for this is that, in addition to the decrease of temperature, the solubility of lead sulfate in sulfuric acid electrolyte will also decrease when the temperature decreases, which will inevitably saturate the lead ions around the plate and force the formed lead sulfate crystal to be dense, which hinders the full contact between the active substance and sulfuric acid electrolyte, thus making the capacity of Riyuetan battery Reduced output.

            If the temperature of sulfuric acid electrolyte is high during the discharge of Riyuetan battery, it will reduce the supersaturation of PbSO4 on the surface of electrode plate in sulfuric acid electrolyte, which is conducive to the formation of loose lead sulfate crystal and the production of thick and solid PbO2 layer during charging, thus prolonging the service life of active substances of electrode plate. If the temperature of electrolyte is too high during the charging of Riyuetan battery, the diffusion of electrolyte will be accelerated, and the corrosion of plate grid will be intensified, so that the service life of Riyuetan battery will be shortened.
