铅酸蓄电池基本原理
Basic principle of lead-acid battery
Principle and application of lead-acid battery
The lead-acid battery consists of several pairs of positive and negative plates overlapping each other to form a pole group.
The storage capacity and battery capacity are determined by the amount of active material (determined by the area, thickness, number of plate pairs and other factors).
In addition, the operation of the battery is also significantly determined by the "effective active surface of the active material". Therefore, the porosity of the active material should be considered frequently.
"Accumulator", from Latin, means "battery" or "energy storage battery". The latter meaning is often used.
The battery stores energy through chemical and electrochemical reactions. That is, electricity is generated by electrochemical process, and vice versa.
During discharge: stored chemical energy is converted into electrical energy.
When charging: store electric energy in the form of chemical energy.
Lead-acid batteries are secondary batteries. (Different from the primary battery, which can only be used for discharge and cannot be charged)
Electronics:
When discharging, when the load is connected to form a current, the electrons flow from the negative pole (through the load) to the positive pole.
When charging, electrons are supplied to the battery through the negative terminal.
In the literature, the opposite statement is often said, that is, when discharging, the current outside the battery flows from the positive pole to the negative pole, while when charging, it flows from the negative pole to the positive pole. This direction is exactly opposite to the direction of electron flow, and is called "the direction of current in engineering". According to the author, the direction of electron flow is "the actual direction of current". This is the basis of the process described in this article, and the two cannot be confused.
An electron is a negatively charged particle. According to where the electrons are supplied during discharge and where the electrons are received during charging, the designation and marking of battery terminals (and plates) are finally specified.
Mark "-" (or "Neg" or "N") as the negative terminal and connect the negative plate.
Mark "+" (or "Pos" or "P") as the positive terminal and connect the positive plate (Positives).
铅酸蓄电池原理和应用
铅酸蓄电池由若干对正、负极板相互交叠形成极群。
活性物质的量(由极板面积、厚度、极板对数量等因素决定)决定了贮存容量和电池容量。
此外,电池运行还显著的决定于“活性物质的有效活性表面”,因此,活性物质的孔隙率应经常考虑。
“accumulator”,来自拉丁语,表示“蓄电池”或“贮能蓄电池”。后面的意思经常使用。
通过化学和电化学反应,电池贮存能量。即,通过电化学过程产生电能,反之亦然。
放电时:贮存的化学能转变成电能。
充电时:将电能以化学能的形式贮存起来。
铅酸蓄电池属于二次电池。(不同于原电池只能用于放电,不能充电)
电子:
放电时,当负载接通形成电流时,电子从负极(经负载)流向正极。
充电时,电子通过负极端子提供给电池。
在文献中往往剪刀相反的说法,即,放电时,电池外部的电流从正极流向负极,而充电时从负极流向正极。这个方向正好与电子流动的方向相反,被称为“工程上的电流方向”。按照作者的观点,电子流动的方向是“电流的实际方向”。这是本篇文章所描述过程的基础,两者不能混淆。
电子是带负电的质点。根据放电时从哪里提供电子,和充电时从哪里接受电子,最后规定电池端子(和极板)的称谓和标记。
标记“-”(或“Neg”或“N”)为负极端子,连接负极板(Negatives)。
标记“+”(或“Pos”或“P”)为正极端子,连接正极板(Positives)。
