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 […]

Researchers at the University of Central Florida have been looking for alternatives for lithium rechargeable batteries which are largely used in every device. Using two-dimensional (2D) transition-metal dichalcogenides (TMDs) capacitive materials, they are building a new supercapacitor that overcomes the performance of conventional lithium battery and replaces its efficiently. Transition metal dichalcogenide monolayers (TMDs) are […]
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 […]
