E-Cell Batteries

Just want to say thank you for the AA and AAA E-cell batteries and chargers throughout the TV and Magazine departments and wanted some feed back. Have to say I’m impressed.

We go through hundreds of AA and AAA batteries each season for our wireless mics, GPS units, head lamps and other accessories.

We have tried rechargeable batteries in the past but gave up on them. So far the E-cell batteries are working better than Duracell pro-cells which we were buying by the case.

Thanks for coming out with an environmentally safe and affordable rechargeable system that performs better than conventional batteries.

How do batteries are made using Lithylene Technology:

A thin sheet of rivet polymer is then applied to the top and bottom of the electrode stack and, under specific heating and pressure conditions, the polymer will penetrate each of the holes (Fig. 4, Fig. 5). Once cooled, the polymer hardens, keeping active materials in contact and providing a very stable battery structure (Fig. 6, Fig 7). The rivet polymer ensures electrical contact between electrode layers, and thereby eliminates the need for a conventional metal can. As the rivet polymer is not chemically involved with redox reactions, thus it will not suffer any detrimental side effects after repeated charge and discharge cycles.

Application Of Batteries

Historically, the battery has been considered a “black box” in product design. Free Form Batteries made using Lithylene technology will revolutionize the way designers and consumers view battery solutions. Applications of Free Form Batteries range from consumer electronics to specialty goods. Free Form Batteries will make use of most, if not all, available space within the host device, resulting in longer product lifetime and better performance.

Ultra Sim- Application of batteries:

Presently Free Form Batteries are limited to rechargeable Li-ion electro-chemistry. Because of the use of standard materials, Free Form Batteries, regardless of shape and dimension, always meet state-of-the-art requirements. Typical cycle life and discharging curves compared against counterparts in standard configuration are depicted for general reference.

If you are not familiar with rechargeable Li-ion system (which is exactly the same as those used in common devices and gadgets such as laptop computers and cellular phones), please refer to following charts depicting discharging curves at different discharge rates, and different temperatures, and please also see the charging curves by constant current in the first stage and constant voltage in the second stage.

Battery capacity is a result of battery volume. For any given design, it is very easy to estimate available capacity using volumetric energy density, which is a figure between 280 and 320 Wh/Liter for the selected electro-chemistry.

To make a quick estimation, please carefully calculate in liters the volume of your design. The capacity you should expect will vary between [(280 x Volume) / 3.7 Volt] and [(320 x Volume) / 3.7 Volt]. The capacity you derive from the equation will be expressed in ampere-hour (Ah) .

Exact capacity is determined by effective use of space after battery assembly. You can place sample order to know better the true capacity of your design
