The current battery system is difficult to meet large-scale electrical storage applications due to cost and resource constraints.
Here we reportorganic Na-
Ion battery using p-
As cathode and n-doped poly-triamine-type redox-active poly(
Anthraquinonyl sulfide)
As an anode, transition is not included-
Metal, such as conventional batteries. Such a Na-
The ion battery works well with a voltage output of 1.
8 kg/v and achieve a considerable specific energy of 92 wh kg-1.
Structural flexibility and stability due to redox-
Active polymer, this battery has excellent rate capability, releasing a capacity of 60% at a very high rate of 16 ° c (3200u2005mA g−1)
And after 85% cycles at 8 ° c rate, excellent cycle stability was shown with a capacity of 500.
Most importantly, this type
Make organic batteries from renewable energy and Earth
Rich materials provide new possibilities for a wide range of energy storage applications.
PAQS were synthesized by the polymerization reaction of NaS and 1,5-
Chloroxone.
Remove the water from the NaS 9HO to obtain the water-free NaS (

Dehydration by boiling benzene at 135 °c
After the evaporation of benzene, the amount of chemical measurement is 1,5-
Two anthraquinone (Alfa Asser)and N-methyl-2-pyrrolidone (NMP)
Add in the mixture and then return for 10 hours at 150 °c under magnetic stirring.
After the reaction is completed, filter the solid and then use de-
Ionised water and acetone and finally dried overnight in a vacuum oven at 60 °c
PTPAn was obtained by oxidation polymerization of triamine monomer (purity ≥ 99.
