final rejection of claims 11 through 15, 17 through 22, and
24. Claims 1 through 10, 16 and 23 have been cancelled during
prosecution of this application.
Claims 11 and 15 are representative and are reproduced
below:
11. A secondary cell, comprising:
a positive electrode;
a negative electrode formed from materials other than
lithium metal; and
a non-aqueous electrolytic solution,
said negative electrode being composed of a carbon
material obtained by carbonizing a natural polymer at a
temperature of from 500EC to 1000EC and having a crystallite
size Lc of 10 Angstroms or less when analyzed by x-ray
diffraction.
15. In a method of producing a secondary cell comprising
a positive electrode, a negative electrode and a non-aqueous
electrolytic solution, the improvement wherein the negative
electrode is produced by a process which comprises carbonizing
a natural polymer at a temperature of from 500EC to 1000EC to
provide a carbon material having a crystal thickness Lc of 10
Angstoms or less when analyzed by x-ray diffraction, the
negative electrode being formed from materials other than
lithium metal.
