Location:Chinese Academy of Sciences > Products  > New Products Sulfur carbon composite anode of lithium sulfur battery
Product code:TNS-1

【Product Description】

     The self-developed graphene/carbon nanotube composite was used as the carrier material of sulfur anode, and the excellent conductivity and abundant void structure of graphene/carbon nanotube were utilized to effectively solve the problems of poor sulfur conductivity of active substance and large volume change during charging and discharging process. The sulfur - carbon composite anode has excellent cycling performance and rate performance.

【Test Suggestion】
 1. This product is black pole piece, single-side coating, easy to absorb moisture, need to be dried before using. Positive sulfur content is 64 wt% ;
2. It is recommended to use ether electrolyte for lithium sulfur battery, DOL:DME=1:1(V:V),1Mol/L LiTFSI;
3. Test voltage range: 1.7-2.8V, generally with 0.2C (1C = 1200 mAh g-1) current density for long cycle test.
