Solid state thin film battery market takes off driven by wireless sensor networks

April 11, 2015 // By Jean-Pierre Joosting
Market research firm RnRMarketResearch in its latest report predicts that solid state thin film battery markets at $9 million in 2014 are forecast to reach $1.3 billion by 2021. Rapid growth toward the end of the forecast period is anticipated as technology improves the cost structure of the manufacturing.

Solid state thin film batteries are ideal for powering energy harvesting applications. According the study, "Solid state electronics brings the same advantages to batteries as it has brought to all other industry segments it touches. Printed circuit board manufacturers are finding that they can achieve a rapid return on investment from substantially decreasing the energy costs associated with using storage by wave soldering the storage onto the boards during the manufacturing process."

The quality of energy storage is better with solid state thin film batteries. Data for thin film batteries using very thin substrates illustrate the longer cycle life that can be achieved. Applications include power bridging, permanent power, and wireless sensor networks.

Thin film battery market driving forces include creating business inflection by delivering technology that supports entirely new capabilities. Sensor networks are creating demand for thin film solid state devices. Vendors doubled revenue and almost tripled production volume from the first quarter. Multiple customers are moving into production with innovative products after successful trials.

A strong business pipeline has emerged with customer activity in all target markets. The market focus is shifting from ramping capacity to driving manufacturing efficiencies and achieving margin improvement, indicating increasing market maturity.

As energy harvesting and wireless sensor networks evolve, the solid state batteries provide an uninterruptable, stable power source that lasts as long as the electronics with which it is packaged. In some cases, changing batteries is not feasible, ant these applications are illustrative of those kinds of instances.
