Both the Lithium-ion (Li-ion) and Sealed Lead Acid (SLA) battery markets are expected to grow over the next several years. Applications with high voltage and capacity requirements are adopting Li-ion technology because of its many advantages- especially the high energy density, small size and low weight that this technology provides. Historically, SLA batteries have had a few superior technical traits, in addition to their extremely low cost, that have kept them leading the majority of the overall battery market. However, recent innovations in Li-ion chemistry has made it extremely competitive in markets that are weight sensitive and inconvenienced by SLA’s need for frequent maintenance. Many devices have required batteries for power back-up and these are primed for direct Li-ion replacement of SLA. In the medical market alone, these applications include infusion pumps, ventilators, wheelchairs and workstation carts. This paper will outline the technical and business considerations involved in converting an existing product from SLA to Li-ion.
Many medical devices are moving from simple back-up power to true portability. This creates challenges unique to medical devices and adds new advances in battery technology that can enhance and differentiate portable medical products. This white paper will look at the following advances in portable battery technology and the special considerations for medical device applications: •Lithium Ion (Li-ion) chemistries' advantages over older technology •Fuel gauging accuracy •Unique form factors using Li-Polymer •Use of Lithium Iron Phosphate for high current and Sealed Lead Acid (SLA) replacement •Sterilization of Li-ion for surgical equipment
Lithium polymer batteries have become common in single-cell consumer applications like cell phones and MP3 players, but industrial and commercial applications are now putting them to good use as well. The thin and custom shaped cells are now used in large, complex packs. This white paper is an overview of the advantages, disadvantages and guidelines for using Lithium polymer based battery packs. It looks at Lithium polymer cells versus metal-cased cylindrical and prismatic Li-ion cells and gives a brief description of battery pack construction considerations.
Battery packs are no longer a simple configuration of cells. They are carefully engineered products with many safety features. The main components include of a battery pack include; the cells, which are the primary energy source, the printed circuit board, which provides the intelligence of the system with features such as the fuel gauge and protection circuitry, the plastic enclosure, external contacts, and insulation.
