EXAMPLE - Quartz tube of 10 dm3 was maintained to a vacuum with a degree of 50 mTorr and radio high frequency of 13.56 MHz and 5W was used. Polymerization of carbon disulfide was performed with mixed gas of argon gas and carbon disulfide in a flow ratio of 1:2 for 12 hours. Subsequently, product (6 g) which precipitated in the reaction container was collected and vacuum dried at 150 degrees C, and poly carbon sulfide of formula -(-C(S1.55)-)n2- (n2 is 2 or more) (5 g) was obtained. The obtained compound contained carbon (19.5 mass%) and sulfur (80.5 mass%). Subsequently, the container was sealed with metal-particle of lithium sulfide (Li2S) (7.5 g) and zinc (5.3 g) having average particle diameter of 3 micrometers, and polycarbon sulfide (200 g) with argon gas atmosphere. Mechano synthesis was performed for 48 hours or more with rotational speed of 200 rpm and a compound of formula -(-Li1.9CS1.9Zn0.47-)n- (22.1 g) was synthesized until the unreacted lithium sulfide and metal fine particle was eliminated completely. The anode was produced using the obtained compound as anode active material, N-methyl-2-pyrrolidone, polyvinylidene fluoride and acetylene black. The obtained anode, disk shaped lithium metallic foil of 0.8 mm thickness and 16 mm diameter as cathode and electrolyte liquid consisting of lithium hexafluoro phosphate dissolved in mixed solvent of ethylene and dimethyl carbonate, were used and a coin shaped secondary battery was produced. The obtained battery had first time discharge capacitance of 784 mAh/g, 2-cycle discharge capacitance of 698 mAh/g, irreversible loss of 10.9%, and 100-cycle capacitance maintenance percentage of 88 %.
