You can say one thing about February 18, National Battery Day: It shows how to make a good that ends up being almost 100% recycled. Figures provided by the Environmental Protection Agency (EPA) show that 99% of lead batteries are recycled, making them the most recycled consumer good in the U.S. It is easy to […]

Lithium Iron Phosphate batteries billed as better alternatives to sealed lead-acid units
Global battery manufacturer Ultralife Corporation is set to enrich the U1 lead acid battery market with the launch of its new 492Wh Lithium Iron Phosphate (LiFePO4) smart battery. The URB12400-U1-SMB battery, which features accurate fuel gauging and integrated safety circuitry, is designed to replace and improve on traditional sealed lead acid (SLA) batteries in applications […]
New anode material brings sodium-ion batteries closer to mainstream use
Sodium ion batteries have been viewed as promising alternatives to lithium ion batteries for large-scale energy storage. But one of their problems has been a rapid degradation after a few charge/recharge cycles. One reason is that sodium ions (1.02 Å) are nearly twice as large as lithium ions (0.59 Å). The large size causes big […]
How to Protect Li-ion Battery Packs
by Ryan Roderick, Intersil Corporation Today’s Lithium-ion (Li-ion) batteries are seeing increasing use in a wide range of applications, including electric scooters, portable power tools, and plug-in hybrid electric vehicles. And designing protection circuitry to safeguard them has never been more important. The power FET is an essential safety function in a battery management system […]
Novel idea for ingestible batteries: Use stomach acid as the electrolyte
A group of researchers have come up with an idea for an energy-harvesting battery that uses body fluids for part of its chemistry. In tests, device delivered an average power of 0.23 μW/mm2 of electrode area for an average of 6.1 days while sitting in the gastrointestinal tract of pigs. They say this power-harvesting cell could […]
