Salt Water Makes Li-Ion Batteries Safer

So far, high-energy lithium-ion batteries were always a matter of concern on account of safety. If you wanted to remain safe from exploding batteries, an aqueous battery such as made from nickel/metal hydride would be preferable, but then it would give you lower energy. Usually, 3-V batteries using aqueous electrolyte technologies are unable to achieve higher voltages because of the cathodic challenge. This happens as the aqueous solution degrades one end of the battery made from either lithium Read more [...]

Non-Toxic Batteries for Humans and Fish

Lithium-ion batteries are very popular nowadays, as everyone has one in their cell phones. Although people use batteries of a large variety of technologies and form factors, everyone wants one with high energy density, low weight and volume, superior charge/discharge characteristics, and low cost. The Lithium-ion chemistry is popular, as it tends to meet most of the above desirable characteristics, even though it has several variations. However, some applications need batteries with unusual construction, Read more [...]

Explosion and Damage Proof High Energy Density Batteries

We seem to spend a major part of our waking life charging batteries of our smartphones, laptops, watches, wearables, and more. Although most of our gadgets work at lightning speeds, one common frustrating weakness lingers on—the batteries. Of course, they have improved tremendously in the last fifty years, yet they have retained characteristics such as being toxic, expensive, bulky, finicky, and most maddeningly, short-lived. The quest for a super battery does not end with smartphones alone, rather Read more [...]
