Technical FAQs 4

Can a thin-film composite membrane improve the power density of a flow battery?

The trade-off between ion selectivity and conductivity is a bottleneck of ion conductive membranes. In this paper, a thin-film composite membrane with ultrathin polyamide selective layer is found to break the trade-off between ion selectivity and conductivity, and dramatically improve the power density of a flow battery.

What are the different types of thin-film batteries?

Thin-film battery technologies There are four main thin-film battery technologies targeting micro-electronic applications and competing for their markets: ① printed batteries, ② ceramic batteries, ③ lithium polymer batteries, and ④ nickel metal hydride (NiMH) button batteries.

What is the electrochemical performance of thin-film printed batteries?

The electrochemical performance of thin-film printed batteries depends on the chemistry. The zinc–manganese chemistry is essentially applied in single-use applications, although some companies, including Imprint Energy and Printed Energy, are developing rechargeable zinc–manganese printed batteries.

Are printed batteries suitable for thin-film applications?

In the literature, printed batteries are always associated with thin-film applications that have energy requirements below 1 A·h. These include micro-devices with a footprint of less than 1 cm 2 and typical power demand in the microwatt to milliwatt range (Table 1) , , , , , , , .
