Understanding the Role of Mn Substitution for Boosting High-Voltage NaFeMn(PO)PO Cathode in Sodium-Ion Batteries.

NaFe(PO)PO is regarded as the most promising polyanionic cathode for sodium-ion batteries (SIBs) due to its superior structural stability, cost-effectiveness, and environmental benignity. However, the low operating voltage inevitably weakens its competitiveness in energy density. Previous works have tried to enhance its operating voltage by Mn doping, which draws on the design idea of LiFeMnPO cathode for lithium-ion batteries, but with little success.

The effect of early systematic rehabilitation nursing on the quality of life and limb function in elderly patients with stroke sequelae.

Objective: To study the effect of early systematic rehabilitation nursing on the quality of life and limb function in elderly patients with stroke sequelae.

Methods: This prospective study was conducted in 97 elderly patients with stroke sequelae. These patients were randomly allocated to the control group (n=49) and the experimental group (n=48).
