Rechargeable Coin Cell Batteries Offer High mAH Capacity

29 July 2016

Illinois Capacitor’s new RJD Series batteries are different in design from other lithium ion coin-cell batteries-- the encapsulation technology significantly increases storage capacity by completely utilizing the space within the cell case.  High power density is a significant benefit in IoT wearable applications.

Not only has the energy density per cell been improved, the failure rate is superior to older designs.  Encapsulation, unlike conventional stacking construction, has resolved older manufacturing issues which can affect safety and reliability.  As a result, RJD Series batteries allow manufacturers to offer new levels of performance without product redesign.

With the increased performance levels, product run time can be increased by 20% or more, as opposed to a conventional lithium rechargeable coin cell battery.  Alternatively, if product size is most critical, performance levels can be maintained with a physically smaller cell.

Because of their internal encapsulation construction, UL-Listed RJD cells also offer greater reliability and safety.  The company says they are more resistant to overheating than conventional coin-cell batteries, and their patented technology virtually eliminates risk of internal shorts.

RJD Coin Cells are available in eight different capacity levels, leaded or with conventional flat terminals.  Each is rated at: 3.7 VDC (4.2 VDC to 3.0 VDC).  Operating temperature range is -20 °C to +60 °C.
