Simple circuit indicates health of lithium-ion batteries
https://www.electronics-lab.com/simple-circuit-indicates-health-lithium-ion-batteries/
Fritz Weld @ edn.com proposes a simple circuit to check li-ion battery health. He writes: Lithium-ion batteries are sensitive to bad treatment. Fire, explosions, and other hazardous condition may occur when you charge the cell below the margin that the manufacturer defines. Modern battery chargers can manage the hazardous conditions and deny operation when illegal […]
Simple circuit indicates a low battery
https://www.electronics-lab.com/simple-circuit-indicates-low-battery/
James Wood @ edn.com writes: The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach seemed more in keeping with the spirit of the project than the use of a single-sourced integrated […]
Flow battery can run for 10 years with zero maintenance
https://www.electronics-lab.com/flow-battery-can-run-10-years-zero-maintenance/
by Jan Buiting @ elektormagazine.com: Harvard University researchers have developed a low-cost flow battery that stores energy in organic molecules dissolved in neutral pH water. In their report (see below) they claim that the new battery can run for a decade or more without maintenance. Flow battery can run for 10 years with zero maintenance […]
2.5V-4.2V input to 3.3V output – 1A Buck Boost Converter using LTC3441
https://www.electronics-lab.com/2-4v-5-5v-input-3-3v-output-1-2a-buck-boost-converter-using-ltc3441/
This circuit can produce an output of 3.3V and 1A current continuously for a voltage input varying from 2.5V to 4.2V. The LTC3441 is a high efficient buck boost converter which plays a vital role in portable instrumentation because of its fixed frequency operation. This circuit produces the output from a single Li-ion battery. Multiple […]
Replacing a dead iPhone battery
https://www.electronics-lab.com/replacing-dead-iphone-battery/
Brian Dipert discuss his experience replacing an iphone battery @ edn.com: About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a “this accessory may not be supported” message appeared on-screen; when I unplugged […]
New PWM controller IC By Microchip Charges Batteries of Any Chemistry
https://www.electronics-lab.com/pwm-controller-charges-batteries-of-any-chemistry/
Battery technologies of all chemistry are experiencing revolutionary changes nowadays. Nanotechnology is leading this revolution by yielding new battery technologies including but not limited to Tiny Supercapacitors and Li-ion batteries that never explode at any condition. But, it’s bothersome to make different chargers for different types of batteries. So, Microchip solved this problem by introducing […]
These tiny batteries can be charged in seconds and last for a week
https://www.electronics-lab.com/tiny-batteries-can-last-for-week/
Battery anxiety is a modern day problem for many of us. Mobile phone and wearable technologies are getting developed rapidly, but battery issues seem to be neverending. As phones and wearables are getting thinner, there needs to be a trade-off between battery life and design. Scientists are searching for a way to make a battery that’s […]
Nanotechnoloy – Nano coating prevents exploding Li-ion batteries
https://www.electronics-lab.com/nano-coating-prevents-exploding-li-ion-batteries/
Lithium-ion batteries are very popular as they’re lightweight and have high energy density. But at the same time, li-ion batteries are very sensitive to overcharge/over discharge. An internal short circuit can cause fire and it may even lead to a violent explosion. Fortunately, nanotechnology found a way to prevent this kind of nightmare. How? let’s […]
Next-generation smartphone battery inspired by the gut
https://www.electronics-lab.com/next-generation-smartphone-battery-inspired-gut/
A new prototype of a lithium-sulphur battery – which could have five times the energy density of a typical lithium-ion battery – overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients. @ cam.ac.uk This gets us a long way through the […]
Lithium-ion battery fires: 7 solutions for improved safety
https://www.electronics-lab.com/lithium-ion-battery-fires-7-solutions-improved-safety/
Steve Taranovich discuss about various ways to enhance Li-Ion batteries safety. Typically, Lithium-ion batteries are safe and reliable. Just think about the $28B market they had in 2013 with a relatively small amount of fires and explosions. But every fire and explosion incident has the potential to cause a loss of life or serious personal […]
