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. This gets us a long way through the bottleneck which […]

I would feel so much safer on my next flight from Phoenix to Silicon Valley if I knew that there were safeguards in place inside passengers’ smartphones that could prevent fire and explosion from such design decisions like a company packing 10 pounds of Lithium-ion battery into a 5 pound compartment or a smartphone owner
Lithium-ion battery fires: 7 solutions for improved safety Read More »
Li-ion cells become more and more popular due to their capacity and reasonable prices. In this entry I will show how to build a simple li-ion battery charger based on MCP73831 chip. It’s a quite useful device for DYI projects,in addition its cost is only around 1,5 euro The device uses USB port as a

Stephen Evanczuk writes: Lithium-ion batteries have emerged as a common energy-storage device in many energy-harvesting applications. For engineers, maximizing battery performance and lifecycle requires use of battery charging circuitry able to account for the specialized characteristics of Li-ion cells
