Lithium-Ion Battery Warms Up, Operates In Subzero Temperatures

A new “all-climate” lithium-ion battery can rapidly heat itself to overcome freezing temperatures with little sacrifice in energy storage capacity and power, researchers say. This advance might enable applications for which high-performance batteries are needed in extremely cold temperatures, such as electric cars in cold climates, high-altitude drones, and space exploration. EC Power is now […]

Charging batteries rapidly and safely

Electronics News Updates / Ibrar Ayyub

Any hobbyist can charge a battery quickly, but can you do it without an explosion, excessive heating or major degradation in battery cycle life? Well many companies have managed fast charging techniques that typically use specialized algorithms. These algorithms take into account the chemistry of the battery and some sort of non-standard charging rate

Circuit provides constant-current load for testing batteries

Electronics News Updates / Ibrar Ayyub

Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the battery. A suitable test current of approximately 250 mA gives you a more reasonable test. You can use a 6Ω resistive load at

Coating makes swallowing batteries safer for curious kids

Electronics News Updates / Ibrar Ayyub

It can be a herculean task to get kids to eat their vegetables, but they’ll happily chow down on things they aren’t supposed to. If one of those things is a button battery, serious injuries can result in the form of burns to the esophagus or tears in the digestive tract. Researchers may not have

Lithium coin-cell batteries Predicting an application lifetime

Electronics News Updates / Ibrar Ayyub

Abstract: The typical specification for lithium coin-cell batteries has been to provide a 10-year battery lifetime in the absence of system power. End users should evaluate the anticipated lifetime in their specific application, especially for those that exceed typical commercial environments or that need to last more than 10 years. This article gives the reader

How to build an open WiFi finder using ESP8266 and two coin batteries

Electronics News Updates / Ibrar Ayyub

n the past few months ESP8266 has created a real revolution in the IoT space. I’m using it in a project that will hit Indiegogo in a month or so and you, of course will support me ☺ During the development process I’ve learned a lot and I want to share a part of it.
