Batteries store and convert chemical energy into electrical energy through electrochemical reactions. They are a critical power source for modern electronics, from smartphones and laptops to electric ...

Lithium metal batteries promise dramatically higher energy density than today's lithium-ion systems, yet their widespread use ...

At first glance, lithium – the least dense solid element in the periodic table – might look like a simple metal characterised by a funny soft texture. However, its use in lithium-ion batteries has ...

As the owner of a 3-year-old laptop, I feel the finite lifespan of lithium batteries acutely. It’s still a great machine, but the cost of a battery replacement would take me a significant way down the ...

Anode – Typically made of reactive materials like lithium or zinc, the anode undergoes oxidation, releasing electrons. Cathode – A material capable of accepting electrons, the cathode undergoes ...

An innovative approach to battery materials could bring sodium-ion energy density and charging speeds far closer to those of ...

The work, led by Chunsheng Wang at the University of Maryland, offers a relatively simple way to make lithium-ion batteries more durable using standard materials and ...

A faulty lithium-ion battery is a serious hazard and can catch fire. Here's what to do if the unthinkable happens - and some preventive measures.

No matter how much you take care of your Lithium-ion power tool batteries, they'll eventually wear out from use. Over time, they suffer from capacity loss, where they no longer hold the same amount of ...
