The table below lists the standard battery sizes currently available in the THINERGY MEC product family. To accommodate various application requirements, custom device sizes are also possible. THINERGY MECs can also be "stacked" to create battery packs with higher capacity. Contact Infinite Power Solutions for more information about micro-energy cells.

All devices have an open circuit voltage (OCV) between 3.9V and 4.1V, depending on the state of charge. The discharge voltage is anywhere between 4.1V and 2.1V, depending on the load current. The batteries are optimized for high pulse current and are perfectly suited for repetitive pulse current applications with no device or capacity degradation. They are similar in performance to a super capacitor, but without the leakage current, and with far superior energy density.

Recharging THINERGY Micro-Energy Cells

The rechargeability feature of the THINERGY MEC is critical for many applications. Just like an automobile that only carries around the amount of fuel needed for a certain amount of use (usage duty cycle), a rechargeable battery allows an application to only carry the amount of energy needed for its usage duty cycle - then it can be recharged and used over and over again. This allows for a much smaller, thinner, and lighter device design.

THINERGY MECs can be recharged beyond 100,000 cycles, making them perfect for trickle charge (constant recharge) applications, such as when used as a backup battery or when integrated with energy harvesting circuits. Re-charge takes only a few seconds to a few minutes, depending on the state of discharge. There is no "memory" effect, so a full discharge and recharge is not necessary to prolong the capacity life of the battery.

Charging Methods

• The batteries can be recharged in several different ways including:

• Infrastructure/Direct wire re-charge - Use of a direct electrical connection of the MEC to a re-charge circuit (conventional method used to re-charge batteries)

• Inductive re-charge - Use of a magnetic field to wirelessly induce a current into a receiving coil with a control circuit that is connected to the battery

• Energy Harvesting solutions such as:

• Solar/Photovoltaics (converting light energy)

• RF (Converting stray or directed radio frequency energy)

• Kinetic (Converting vibrational energy)

• Thermoelectric (Converting changes in heat energy)

The energy harvesting solutions provide a continuous, autonomous power source that, depending on the design, may provide a sufficient trickle charge to the battery such that a conventional direct wire recharge may never be needed, allowing decades of power without battery replacement.
