Cobalt sulfide (Co3S4) nanoparticles of 17.0 nm in crystal size have been successfully synthesized by the reaction of cobaltous acetate (Co(H3COO)2·4H2O) and TAA (CH3CSNH2) under microwave irradiation. The samples were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). SEM image of the as-prepared Co3S4 shows the sphere-like structure. The electrochemical tests were conducted using CR2302 cointype cell, which consists of a cathode and a lithium metal anode, separated by a porous polyethylene film (Cellgard 2500). The microwave synthesis of Co3S4 and possible electrochemical reaction mechanisms were primarily analyzed. The results indicate that the Li/Co3S4 cell system has first discharge capacity of 336mAh/g, indicating that the Co3S4 sample shows potential application as anode in lithium-ion battery.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
