Picosun’s ALD solutions transform battery technology

Picosun Oy, the leading supplier of advanced ALD (Atomic Layer Deposition) thin film coating technology, now provides ALD equipment to transform battery manufacturing.

The sustainable energy economy of the future, greener transportation, and the increasing number of portable, mobile and personal electronic devices all require improved means for local energy storage. Nanostructured, solid-state thin film batteries offer a disruptive solution for this. Replacing traditionally used liquid materials in the battery with all solid layers improves the battery safety and lifetime. Thin and flat geometry makes the batteries easily integrated in e.g. wearable electronics, whereas their nanoscale tailored internal structure enables high energy storage capacity.


ALD is an ideal way to prepare the highly conformal, dense, uniform, and structurally and chemically exactly controlled functional layers in the core of the battery stack. Using PICOSUN™ ALD equipment, imec, Belgium, has now developed a solution to deposit a novel, solid electrolyte for lithium ion thin film batteries.

“Our aim at Picosun is to utilize ALD technology for better tomorrow. For example, faster and smoother data handling and communications, and the increasing number of mobile, wearable personal health monitoring devices require compact, efficient, and reliable power delivery solutions. The ALD technology we have now developed with imec for manufacturing of safe and long-lasting thin film batteries is an important breakthrough into a huge market area still relatively new to ALD. We are happy to provide the latest manufacturing solutions to our customers in this field and to see their most advanced products powering our everyday electronics,” states Juhana Kostamo, Managing Director of Picosun.

Picosun’s manufacturing solution for the novel lithium ion battery materials consists of an ALD system integrated with a glove box and operating under argon atmosphere to eliminate airborne contamination and air-induced deterioration of sensitive precursors. Industrial scale, large volume Picohot™ 350 precursor sources allow efficient precursor evaporation in high concentrations at temperatures up to 350oC, with long system uptime and minimum number of maintenance breaks.
