ionic liquid electrolytes supporting high energy density in sodium-ion batteries based on sodium vanadium phosphate composites - li ion battery cell
Sodium-ion batteries (SIBs)
Widely regarded as alternative, sustainable and cost-
Effective energy storage device for large equipment
Expand energy storage applications.
In this work, an easy-to-manufacture sodium vanadium phosphate
Carbon composite materials (NVP@C)
The cathode material has good rate capability and long cycle life (
89% to maintain capacity at a speed of 10C after 5000 cycles)
Ionic liquid electrolyte for room temperature sodium metal batteries.
Full-electric performance
At room temperature, battery lithium ion batteries with NVP @ C and hard carbon electrodes were studied with ionic liquid electrolyte.
Battery power is 368 W h kg-
The energy density and 75% capacity after 100 cycles are maintained, which is better than organic electrolyte-based devices.
