LiTE STAR
THE SOLID STATE, THIN-FILM, LITHIUM BATTERY
• Taking the next step with thin-film flexible energy storage
• Going where no other battery is able
• Inside the product for life
Product development specialists across many industries are
finding innovative ways to exploit the performance life in the
LiTE*STAR™ Battery. Life cycle testing has exceeded 60,000
full depth of discharge cycles and an end of life limit has yet to
be reached.
As a result, the LiTE*STAR™ Battery can be engineered inside
the product for life as a fully integrated device within the
electronic circuitry. In many applications, a micro-amp-hr
battery is sufficient where an internal or external source (i.e.
RF Energy) is present for recharging the battery.

LiTE*STAR™ is available in flexible or rigid formats and can
be engineered to specific patterns, shapes, and sizes.
