Half-cell and full-cell

What is half-cell cumulative efficiency?

Half-cell cumulative efficiency provides a visually striking representation of the effect of less than unity CEs and yields a semiquantitative approximation of the expected capacity retention in full-cells.

How is a full cell made?

The full cell was assembled by hard carbon and Na 3 Fe V 1.5 (PO 4) 3 nanoparticles. The outstanding electrochemical properties were achieved in the half and full cell. Pristine Na Fe V (PO) 3 and carbon-coated Na 3 Fe 0.5 V 1.5 (PO 4) 3 nano-particles are synthesized by one-step solid-phase reaction method.

Is half-cell cumulative efficiency a good approximation of full-cell reversible capacity fade?

Most importantly, the half-cell cumulative efficiency data trajectory closely tracks that of the full-cell reversible capacity (Figure S2 in the Supporting Information), indicating that half-cell cumulative efficiency is indeed a good approximation of the expected full-cell capacity fade due to Li-inventory consumption.

What is a half cell electrolyte?

In the half cell, the lithium metal foil was used as the counter electrode, Celgard 2400 microporous film as the separator and 1 M LiPF 6 in ethylene carbonate (EC) and diethyl carbonate (DEC) (1:2,v/v) as the electrolyte. The cells were assembled in the argon-filled glovebox.

Are half-cells based on CE and capacity?

This cumulative efficiency data provides a perfect illustration of the limitations of solely presenting CE and capacity results in half-cells, especially on non-informative scales.

How were half cells assembled?

Half cells were assembled using the CR2032 coin-type cells with Na metal as the counter and reference electrode along with Celgard 2400 as the separator.
