Innovators continue to search for abundant, inexpensive energy. The latest introduction is an innovative micro-energy storage device developed by Infinite Power Solutions, Inc. (IPS), a maker of solid-state, rechargeable, thin-film devices. The company recently unveiled its THINERGY™ family of micro-energy cell (MEC) products. THINERGY MECs are powerful batteries for their size and compete with Lithium (Li) coin cells, printed batteries and other thin-film batteries (TFBs).
With their significant discharge current, these batteries can replace supercapacitors where minimum volume and maximum energy density is critical. When combined with circuits that harvest ambient energy from sources such as solar, force, vibration, thermal and radio frequency (RF), MECs can be perpetually recharged to power wireless sensors and other micro-electronic devices–for a safe, reusable and clean energy source that lasts the lifetime of a system with no maintenance or replacement cost.
When recharged over their lifetime, these devices provide tens of Watt-hours of energy, equivalent to more traditional primary cells that are hundreds of times larger in total volume. Four standard products are within the product family. Two products are available now, the THINERGY MEC101 and THINERGY MEC120, with capacity options up to 1.0 mAh and 0.4 mAh, respectively. The other two products will be available later this year. Key features include:
– Ultra-thin and flexible package fits difficult-to-fit spaces
– High-power discharge eliminates need for external boost capacitors for high-pulse currents
– Can be deeply embedded and laminated within PCBs or other materials
– Solderable tabs on metal foil package simplify mounting and electrical connections
– Rapid recharge in seconds to minutes, depending on the state of charge
– All solid-state chemistry with no liquid or polymer (organic) electrolyte used
– Low leakage with less than 1% reversible charge loss per year
Life cycle of these batteries is listed as 10,000 cycles at 100% depth of discharge (DOD) and 80% capacity retention.
