Ultralife Batteries is a global battery solutions specialist for diverse applications. The company develops and manufactures a wide range of standard as well as customised lithium primary, lithium ion and lithium polymer rechargeable batteries. Some examples follow.
Today's active RFID and tracking applications require reliable, lightweight, long-life power sources. Ultralife's Thin Cell and HiRate cylindrical lithium-manganese dioxide (Li-MnO2) primary (non-rechargeable) batteries and Ultralife polymer and lithium ion rechargeable batteries are suited for a wide variety of tracking and active RFID products
Providing a stable voltage over a wide temperature range, its lithium primary and rechargeable batteries are an advanced power source. Li-MnO2 chemistry allows full-rated capability at start-up (no voltage delay) and is safer than comparable lithium systems. For active tag applications, a wide range of lightweight, low profile 3 or 6 V lithium Thin Cell or HiRate cylindrical batteries are available for a unique combination of low profile, high energy, long shelf and operating life, and wide operating temperature range.
These lithium Thin Cell batteries are wafer-thin at 2,0 mm. With their ultra-thin prismatic form and a high ratio of active materials to packaging, Thin Cells operate over a wide temperature range and can efficiently fill virtually any battery cavity. They are available in a variety of sizes and capacities.
Ultralife's lithium HiRate cylindrical batteries are considered a breakthrough in lithium battery technology. A spiral-wound design provides high capacity with high rates of discharge, even in extreme temperatures. HiRate batteries provide ultra-high rates of discharge in extreme temperatures without voltage delay at start-up, even after long periods of storage. Significantly safer than comparable high-rate systems, Ultralife HiRate batteries have a 10-year shelf life and are environmentally friendly. Their high-rate current capability and instant start-up makes them ideal for applications such as heavy-duty GPS transponders and other applications requiring long transmission range and extended shelf and usage life over a wide temperature range.
Ultralife lithium ion prismatic and polymer batteries are ideal for portable handheld and remote tracking and RFID applications that require lightweight, long-life rechargeable batteries.
Lithium ion batteries outperform both NiMH and Ni-Cd batteries, says the company. Its lithium ion prismatic batteries have high energy density, high capacity and long cycle life in the most common, lightweight sizes. Unlike NiMH and Ni-Cd batteries, they have very low rates of self-discharge, do not exhibit a memory problem and are available in a wide range of capacities.
Lithium polymer batteries are thin, lightweight and powerful. Ultralife's polymer batteries combine high-energy lithium ion chemistry with state-of-the-art polymer technology. Every battery component is solid - there are no liquids that need to be contained by steel or aluminium cell housings. The result is a powerful, safer, thin and lightweight rechargeable battery with a wide operating temperature range. Polymer batteries have very low rates of self-discharge and do not exhibit a memory problem, meaning that they can be recharged at any state of charge without first having to be completely discharged. They are available in a wide range of thicknesses and capacities.
