Free battery instead of lithium phone
Lithium-ion batteries power everything from smartphones to electric vehicles today, but safer and better alternatives are on the horizon. Li-on batteries have a number of drawbacks, which have affected everything from iPhone production to the viability of electric cars. Some of these problems include: 1. Let's start with a battery technology that doesn't stray too far from the Li-on baseline we're familiar with. Sodium-ion batteries simply replace lithium ions as charge carriers with sodium. This single change has a big impact on battery production as sodium is far. A lithium-ion battery uses cobalt at the anode, which has proven difficult to source. Lithium-sulfur (Li-S) batteries could remedy this problem. Lithium-ion batteries use a liquid electrolyte medium that allows ions to move between electrodes. The electrolyte is typically an organic.
