The mechanism of vacuum thermal recycling was also discussed. Results show that vacuum distillation is a very effective separation method for waste Ni-Cd batteries. At a constant......
electrolyte could significantly reduce potential safety risks of rechargeable batteries. Na-superionic conductor(NASICON)-structured solid electrolyte is one of the most promising sodium solid electrolytes and can be employed in solid-state sodium batteries. In this work, a NASICONstructured solid electrolyte Na3.1Zr1.95Mg0.05Si2PO12 was synthesized through a facile solid-state reaction, yielding high......
