Thinfilm Announces First Multi-Cell Solid-State Battery
Oslo, 15 October 2020

Thin Film Electronics ASA ("Thinfilm" or the "Company"), a developer of
ultrathin, flexible, and safe energy storage solutions for wearable devices and
connected sensors, today announced significant progress in device manufacturing
and packaging innovation in support of its premium microbattery products based
on solid-state lithium battery ("SSLB") technology.

To enable ultra-compact, energy-dense, milliamp-hour-class batteries, Thinfilm
has successfully demonstrated the first multi-cell battery based on its SSLB
technology. By stacking and encapsulating multiple layers of active cell
materials deposited on Thinfilm's unique stainless steel substrate, Thinfilm can
flexibly scale energy storage capacity within the compact footprint required in
applications with constrained form factors.

Innovations in steel-substrate cell stacking are essential to creating solid-
state battery products for hearing aids, earbuds, on-body sensors, and other
products prioritizing size and shape. By overcoming packaging limitations that
have previously prevented wider use of solid-state technology, Thinfilm is
expanding the technology's many benefits to previously unaddressed markets.

Thinfilm's consolidated manufacturing environment in Silicon Valley continues to
accelerate technology and product development cycles and has led to ongoing
improvements in device yield, reliability, and performance of the critical
materials responsible for energy storage and charge cycling. As a result,
Thinfilm's battery development engineers have recently implemented and validated
multiple process integration and materials advancements in the Company's on-
site, fully functional, and scale-ready flexible electronics factory.

Based on continued positive feedback regarding the advantages of Thinfilm SSLB
technology, the Company has broadened its engagements with leading manufacturers
of wearable devices and connected sensors. Substantive conversations with a
growing list of prospects have validated Thinfilm's stated market priorities and
led to the incorporation of meaningful customer feedback in the Company's SSLB
roadmap and technology development priorities. For example, recent success in
multi-cell stacking reflects the prioritization of energy-dense batteries
suitable for integration into form-factor-constrained applications such as
hearing aids, earbuds, and medical devices. Improved cycling counts, compared to
legacy lithium-ion batteries, address the long-term reliability needs of devices
requiring daily charging. Enhanced output currents enable reliable Bluetooth LE
transmit performance needed to communicate on-body vital sign sensor data to a
companion smartphone.

Thinfilm has established a priority sampling program for customers and partners
intending to incorporate SSLB products into their technology roadmaps. Following
successful completion of standard characterization, reliability, and shipment
acceptance testing, the Company plans to deliver alpha samples to lead
customers.

Thinfilm is Energizing Innovation(TM) with ultrathin, flexible, and safe energy
storage solutions for wearable devices, connected sensors, and beyond.
Thinfilm's innovative solid-state lithium battery (SSLB) technology is uniquely
positioned to enable the production of powerful, lightweight, and cost-effective
rechargeable batteries for diverse applications. The company's state-of-the-art
flexible electronics manufacturing facility, located in the heart of Silicon
Valley, combines patented process technology and materials innovation with the
scale of roll-to-roll production methods to bring the advantages of SSLB
technology to established and expanding markets. Thin Film Electronics ASA is a
publicly listed company in Norway with corporate headquarters in Oslo and global
headquarters in San Jose, California.
