Common Table Sugar Key to Allaying Safety Concern in Aqueous Zinc Batteries

Researchers designed a sucrose-modified aqueous electrolyte that increases the mobility of zinc ion in response to the electric field and successfully achieves dendrite-free zinc batteries without compromising electrochemical performance.

­Due to their low cost and environmental friendliness, aqueous zinc batteries have the potential to play an important role in future energy storage systems for applications like the power grid. However, a safety concern has slowed the progress of this emerging technology. In a July 28 study published

Batteries and Energy Storage

Kevin Parmenter, Director, Applications Engineering. TSC, America

­Batteries are a hot topic. Prior to the pandemic, I counted about 355 battery-centric events being held worldwide over a year-long period – almost one a day. This comes as no surprise since the global battery market was valued at USD 108.4 billion in 2019 and is expected to have a compound annual growth ra

Next-Generation Battery Management System Architectures

­DC fast chargers take between 30 to 45 minutes to charge the battery to 80 percent. This fast charging process generates a significant amount of heat, because the internal resistance to the high current generates a temperature rise. For a typical 400 V EV battery, therefore, the charging rate is limited by se

Application of Power MOSFET in Battery Management Charge-Discharge System

Click image to enlarge

Figure 1. Battery protection board circuit diagram

­Power MOSFETs are required to be connected in series between the inside of the lithium-ion battery pack and the output load. At the same time, the dedicated IC is used to control the on and off of MOSFET for managing the charge and discharge of the battery, as shown in Figure 1. In consumer electronic systems, su

The Ubiquity of Lithium-Ion Batteries

Jason Lomberg, North American Editor, PSD

­It’s beginning to look a lot like…normalcy. And for someone who gets cabin fever when I’m stuck inside for even a day, I couldn’t be happier. New COVID-19 cases continue to drop, from a U.S. 7-day average of nearly 700K as of 1/24 to 85K as of 6/21. Obviously, tens of thousands of instances of some
