固体的许多性质是其比表面的函数,如化学反应中所用的催化剂,其表面积的大小直接影响化学反应的速度,而在化学电源中,电极的表面积或制备电极活性物质的材料的表面积的大小也会影响电极的电化学特性,如烧结活性炭电极,如果增加其真表面积可增加空气去极电极的活性。而在炭焦化达30％时,氧在炭 Many of the properties of solids are a function of their specific surface area, such as the catalyst used in chemical reactions. The size of the surface area directly affects the rate of chemical reaction. In a chemical power supply, the surface area of ​​the electrode or the surface area of ​​the electrode active material Also affect the electrochemical properties of the electrode, such as sintered activated carbon electrode, if you increase its real surface area can increase air depolarization electrode activity. In the carbon coking up to 30%, oxygen in the carbon
