Advantages and challenges of lithium batteries

Jan 23, 2024

Lithium batteries are rechargeable batteries that use, yes, you guessed it, lithium. This element is present in the battery as the cathode material. Lithium batteries have become popular due to its countless advantages. It's got high energy density, low self-discharge, a long life, and is environmentally friendly. Because of these perks it’s now being used everywhere from mobile phones to electric vehicles. Despite all this it still faces some safety issues and costly problems.

The main concern is safety when dealing with lithium batteries. Overcharge it, overdischarge it, short-circuit them or even hit one hard enough and things can get dangerous really fast. The battery can become unstable and cause thermal runaway which leads to fire, then explosion. Yeah not ideal at all. So in order to make them safer we’ve got to find ways to optimize and improve the battery’s structure, materials, management system...The list goes on.

Cost is another big problem for lithium batteries. Energy consumption in the manufacturing process is extremely high because of how much water and chemicals are required throughout production. On top of that lithium isn’t evenly distributed across Earth so it's actually pretty expensive too because of its scarcity. These two factors combined make lithium batteries difficult to mass-produce economically which limits its chance at becoming a widely used item.

Lastly we come to recycling and disposal which is important for every product yet we always seem to struggle with this part of development as well as spread of knowledge about proper disposal methods.. If someone doesn’t know how they might throw a battery out in their normal trash bin with everything else not knowing what hazards they could have caused for others down the line.. When lithium batteries reach their service life end they need be disposed in a very specific way or else we risk pollution and waste of resources. The metal elements inside these batteries will serve us again if recycled properly too! We’ll be able to both save money and resources.

Overall lithium batteries are a great solution but we can’t ignore the problems they come with. Instead of ignoring these problems we should try to find ways to improve the battery and make it even better than it already is!
