This unique device substantially outperforms all other small form factor electrochemical energy storage technologies, including 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 temperature 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. External terminals in the form of metal tabs run along the length of the cell on two opposite edges to provide contact when connecting to wires, a PCB, or stacking the cells into a module. These tabs also allow easy connection to both terminals from either side of the cell, which is important during auto- mated assembly onto flex circuits and printed circuit boards (PCBs). The highly conductive metal tabs allow various connection methods including epoxies, anisotropic conductive film (ACF) materials, and lead-free solder. The cells can be oriented to stack in series (to multiply voltage) or in parallel (to multiply capacity and power). The MEC101 is an extremely thin energy storage device that can withstand the heat and pressure of hot lamination processes, allowing it to be deeply embedded into rigid or flex PCBs, multi-chip modules (MCM), or system in package (SIP) implementations. The active materials in the device include a LiCoO2 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 power performance.

DS1001 v3.4 Product Data Sheet www.InfinitePowerSolutions.com THINERGY™ MEC101: Solid-State, Flexible, Rechargeable Thin-Film Micro-Energy Cell results in ultra-low self discharge, making this technology ideal for applications using ambient energy harvesting charging solutions. In addition, this technology emits no toxic chemicals, 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 encapsulation methodology is used to ensure reliability and performance under harsh environmental 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 batteries 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, depending 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 charge voltage greater than cell voltage (not to exceed the maximum specified recharge voltage) will result in charging. A variety of 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, magnetic, or thermal energy. The low self-discharge rate results in decades of shelf life. With its recharge cycle stability, the device offers thousands of recharge cycles for many years of use with no memory effects. The MEC101 provides an extremely safe, reliable, and low-cost energy storage solution that outperforms any other micro-battery or capacitor solution. This component class device is designed in for the life of the product.
