Battery Safety Standards Update: IEC 62133 Undergoes Major Changes
Commentary Contributed by John C. Copeland, Co-Owner and Technical Manager, Energy Assurance LLC
The IEC 62133 family of standards has enabled international harmonization of safety testing for small-format cells and batteries since its initial release in 2002 followed by a major revision in 2012. Recognizing the substantial shifts in the rechargeable battery market from nickel to lithium chemistries, the standard underwent its most dramatic change in 2017. This article will familiarize the reader with those latest changes and their impact on attaining cell and battery pack compliance.

Whether you are most interested in xEV expansion, raw material development, partnering, or R&D, the event will address some of the fundamental questions facing the industry and roadmaps for the future.
Honey, I Shrunk the Battery!
Commentary contributed by J.D. DiGiacomandrea, Applications Engineering Manager, Ultralife Corp.
In 2011, Chinese engineers claimed to have made the world's first shrinking device. While it may sound like it came from a film, the device only creates the illusion of a smaller object, rather than actually shrinking it. Illusions aside, it is clear that devices in the electronics sector are continuing to get smaller. Thin cell batteries are some of the smallest batteries available on the market. However, despite their small size, they are capable of providing a stable voltage to power electronic devices and outperform coin cells at higher discharge rates. So what makes thin cells different from other types of batteries on the market?
