Powermat and Leyden Energy Announce Partnership to Develop High-Density, Heat-Resilient, Wirelessly Chargeable Batteries
Leyden Energy, Inc., a manufacturer of advanced lithium-imide (Li-imide™) batteries, announced an agreement with Powermat Technologies, a specialist in wireless charging technology for smartphones and other consumer electronics, to develop high-density, heat-resilient Li-imide battery cells and packs with embedded wireless charging functionality that will provide consumers with a high quality mobile experience.
As part of the collaboration announced today, Leyden Energy will supply Powermat Technologies with a battery thin enough to embed Powermat Technologies’ wireless charging technology onto the battery cell itself without compromising the cell’s original battery capacity. The technology is expected to have a distinctive set of technological advantages – namely, embedded wireless charging technology, enabling tethering-free charging of the phone and the battery by itself, longer battery warranty thanks to higher cycle and calendar life rating and higher temperature resilience, stemming directly from Leyden Energy’s patented, thermally superior Li-imide chemistry platform, the future of lithium-ion (Li-ion) power.
"Powermat Technologies was the first company to bring to market batteries for smartphones that incorporate wireless charging," said Ran Poliakine, Powermat Technologies’ CEO. "Thanks to Leyden Energy’s higher volumetric and gravimetric energy density, wireless charging batteries can now have the same energy density as equivalently sized standard batteries."
The integration of embedded wireless charging functionality requires a thinner battery to allow space for the new technology layer that enables charging; typically, using standard Li-ion batteries with their heat-sensitive LiPF6 (lithium hexafluorophosphate) electrolyte, this reduction in battery size would mean sacrificing battery capacity and compromising on charging speeds. But now with its patented Li-imide chemistry platform, Leyden Energy can produce thinner batteries that deliver equal or higher energy density in a smaller volume than leading competitors’ batteries without sacrificing cycle life or calendar life.
"We are excited to partner with the industry leader to address the growing demand for wireless power," said Leyden Energy CEO Aakar Patel. "Shaving close to a millimeter off the height of a typical legacy Li-ion cell to embed Powermat Technologies’ wireless charging solution and coil directly onto the battery cell would typically diminish battery run-time, but our patented Li-imide chemistry platform offers a compromise-free solution."
Opinion: Unraveling the Ultra-Low Power Design Issues
Leyden Energy’s battery products are perfectly suited for consumer electronics applications due to their higher energy density, reduced swelling, higher levels of safety and excellent thermal properties. These attributes also make Leyden Energy’s batteries well suited for use in EVs and the harsh conditions associated with grid and backup storage applications.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
