Question
# I# a$ y; ]2 F/ r4 AIEC 62133 refers to Clause 5.1 of IEC 61960 for cell and battery designation.
Clause 5.1 of IEC 61960 requires the use of I or L for the designation of the negative electrode (A1) of the cell (or battery) and more precisely, L can be used when the negative electrode is a metal Lithium or any other alloy of Lithium.
For the positive electrode designation (A2), five elements have been numbered (C, N, M, V, T), without the possibility of usage of their alloy. This situation raises four questions regarding the designation of A2, the positive electrode.
1) What can be A2 in case of any alloy of each of the five listed elements (C, N, M, V, T)?
2) What can be A2 in case of an alloy build up with two or more of these five elements?
) W' B% N8 a% }7 b4 y# t1 J3) How shall the designation of the positive electrode made with elements other than these five elements be handled?
4) How shall a positive electrode which is an alloy of elements other than these five elements be designated?
