今天在文献中看到公式,
S=3*w*V/R
S: the total electroactive surface area of electrode j (j代表正极或者负极)
w: the volume fraction of solid phase active material in electrode j
V: the total volume of that electrode
R:radius of spherical intercalation for electrode j
我想请问这些物理量如何得到?尤其是V-正极(或负极)的总体积,在电池设计的参数中有这一项吗?如果对电池解剖能获得这些参数吗?
