This unique device substantially outperforms all other small form factor electrochemical energy storage technologies, includ- ing supercapacitors, printed batteries, and other thin-film batteries. The device is fabricated on a metal foil substrate to achieve its flexibility, thin profile, broad operating temper- ature range, and long life. The MEC is offered in a unique, patented package design that maximizes the active area of the cell and minimizes the device footprint to deliver the highest energy and power density of any energy storage element of its size and thin- ness. External terminals in the form of positive and negative nickel-plated tabs are located along the top edge of the cell for easy soldering to printed circuit boards (PCBs). The tabs are supported with a flex circuit for added strength and to keep them planar with the rigid or flex PCBs. Through-holes located in the terminal contacts allow the MECs to be aligned on solder posts for easy connection and cell stack- ing to create battery modules with higher capacity and current. These tabs also allow easy connection to both ter- minals from either side of the cell, which is important during automated assembly onto flex circuits and PCBs. The con- ductive metal tabs allow various connection methods, including epoxies, anisotropic conductive film (ACF) materi- als, and solder. The cells can be oriented to stack in series (to multiply voltage) or in pa rallel (to multiply capacity and power). The active materials in the device include a Lithium Cobalt Oxide (LiCoO 2) cathode and a Li-metal anode. A solid-state electrolyte called LiPON (Lithium Phosphorus Oxynitride), with its high Li-ion conductivity, is used to provide superior THINERGY® MEC202 Solid-State, Flexible, Rechargeable Thin-Film Micro-Energy Cell DS1015 v1.2 Product Data Sheet [actual size] Mass: 975 mg

DS1015 v1.2 11 July 2012 www.InfinitePowerSolutions.com Product Data Sheet 2 THINERGY® MEC202: Solid-State, Flexible, Rechargeable Thin-Film Micro-Energy Cell power performance. The extremely low electron conductiv- ity within LiPON results in ul tra-low self discharge, making this technology ideal for applications where energy must be reliably stored for many years without the ability to recharge, or for low-power ambient energy harvesting charging solutions. In addition , this eco-frie ndly technology contains no toxic chemicals or heavy metals, providing industry-leading safety with absolutely no possibility for chemical leakage, thermal runaway or fire, as experienced with other Li-ion batteries using liquid or gel electrolytes. A proprietary flex-circuit encaps ulation methodology is used to achieve the ultra-thin and flexible form factor and to ensure reliability and perfor mance under harsh environ- mental conditions, far exceeding other micro-energy storage technologies. The thin form factor, rechargeability, and high discharge rate capability enable applications where conventional coin/button or primary thin ba tteries are not well suited. Due to its low internal cell resistance, the MEC offers superior charge acceptance, making it an ideal energy storage device for applications where extremely low current recharge sources are available, including various ambient energy harvesting methods. Pulsed or continuous currents as low as 1 µA can be used to effectively recharge this device. The MEC recharges in seconds to minutes, depend- ing on its state of discharge and available charge current. MECs can be recharged using constant current, constant voltage, pulsed current, or pulsed voltage sources. Any con- stant voltage (CV) charge greater than cell voltage (not to exceed the maximum specified charge voltage) will result in safe and rapid charging. Unlike conventional lithium ion bat- teries, MECs do not require temperature monitoring during charge, or current limiting by using a complicated constant- current /constant-voltage (CC/CV) charge algorithm. MECs use a simple CV charge method that is fast and totally safe, regardless of the state of ch arge. A variety of CV charging methods can be used, such as direct connection to a power supply, wireless recharge via inductive coupling, or energy scavenging solutions that harvest kinetic, solar, RF , mag- netic, or thermal energy. The low self-discharge rate results in decades of shelf life. With its recharge cycle stabilit y, the device offers tens of thousands of recharge cycles for many years of use with no memory effects. The MEC202 provides an extremely safe, reliable, and low-cost energy storage solution that outper- forms any other micro-battery or capacitor solution. This component class device is intended to be designed in for the life of the product.
