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.
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.
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), , , , , , , .
If a thin-film battery has a thickness of approximately 0.5 mm and needs to deliver the current at 3 V (adapted for silicon circuitry), this equates to an energy density of 6–60 W·h·L −1. Unfortunately, information on energy density or areal capacity is not always available in previous reports.
Low-cost flow batteries with high power density are promising for energy storage, but membranes with simultaneously high ion conductivity and selectivity should be developed. Here the authors report a thin-film composite membrane that breaks the trade-off between ion conductivity and selectivity.
