New electrolyte promises to rid lithium batteries of short-circuiting dendrites

Leave a Comment / Electronics News Updates / By

Dendrites – thin conductive filaments that form inside lithium batteries – reduce the life of these cells and are often responsible for them catching fire. Scientists working at the Pacific Northwest National Laboratory (PNNL) of the US Department of Energy claim to have produced a new electrolyte for lithium batteries that not only completely eliminates …

A low-magnification tunneling electron microscope (TEM) image of Gr–Si nanoparticle (NP). (b) A higher-magnification image for the same Gr–Si NP from the white box in a. (Insets) The line profiles from the two red boxes indicate that the interlayer spacing between graphene layers is ~3.4 Å, in good agreement with that of typical graphene layers based …

With MCP73831 you´ll charge lithium cells easily and safely

Leave a Comment / Electronics News Updates / By

Li-Ion a Li-Polymer cells are becoming a No.1 choice for many applications, where they persuade by high energy density, low weight, low self-discharge and for majority of applications also by their favorable flat shape (Li-Po). Their price is also affordable (in regard to their properties) and so there´s usually only one “difficulty” – to solve …

Lithium coin-cell batteries Predicting an application lifetime

Leave a Comment / Electronics News Updates / By

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 …
