Real-Time Battery Modeling in HiL Testing of Battery Management Systems
Paul Goossens, Vice President, Engineering Solutions, Maplesoft

Demand growth for rechargeable batteries in products such as portable electronic devices, electrified vehicles (EVs) and decentralized power utilities (smart grids) is nothing short of robust. With forecasted annual growth pegged at 8 percent by the Freedonia Group, the global battery market will reach almost $74 billion this year. Rechargeable batteries will account for about 82 percent of that, or $60 billion, according to market researcher Frost & Sullivan. <read more>

Energy Density Comparison of Silver-Zinc Button Cells with Rechargeable Li-Ion and Li-Polymer Coin and Miniature Prismatic Cells

Ross Dueber, Ph.D., President and CEO, ZPower, LLC

Silver-zinc batteries have the highest theoretical specific energy (Wh/kg) and energy density (Wh/L) of all rechargeable battery technologies available commercially today. Rechargeable silver-zinc batteries have been successfully used for decades in military and aerospace applications where high energy and power density are required.  The electrochemical reaction involves the oxidation of zinc to zinc oxide and the accompanying reduction of silver(II) oxide to metallic silver. The reaction at the AgO cathode involves a two-step oxidation (1.8 V and 1.5 V) of two water molecules to form hydroxide anions that migrate to the anode where they oxidize the metallic Zn to form the soluble zincate species before precipitation of the zinc oxide. <read more>

White Paper

Using Fujifilm Prescale During The Manufacture and Test of Li-Ion Cells and Batteries
Sensor Products, Inc.

It is generally accepted that battery manufacturers reject over five percent of cells during manufacturing and testing. Two major causes of these rejects are cell leakage and failure of formation cycling and charge-retention tests. Leakage usually occurs when there are defects in the perimeter seals of cells or in fill tubes. Cycling and charge-retention problems are a result of defects in positive and negative electrodes. For economic reasons, all cell and battery manufacturers strive to eliminate these costly rejects. <read more>

Expanding Technology for Advanced Battery Applications & Fuel Cells

Dexmet has taken the “Expanding Technology” to the next generation of advancements, the micro-mesh material manufactured by Dexmet is infinitely variable, and the proprietary equipment developed anddesigned at Dexmet produces expanded material with smaller holes than anyone else and produces material that is thinner than anyone else in our marketplace. The expansion process produces a very consistent product as far as open area, hole size and conductivity.

Dexmet expanded materials are perfect for Advanced Batteries Applications and Fuel Cells, especially where you are using multi stacks of materials and you need consistent conductivity from stack to stack also the expansion process is more cost effective unlike perforated material.

The expansion process allows you to yield higher amounts of material than what you put in, this is especially important when your application requires expensive materials like platinum, niobium, zirconium and titanium.
