Possibility Crab Shells to Replace Lithium

I believe all of us familiar with, and even use Lithium battery in our daily life. Just few examples of products which are using Lithium Ion battery are Tablets, Cell phones, Laptops and Portable drills.

At least, there are three advantages of Lithium Ion batteries compared to traditional ones:

- last longer

- higher power densities

- and charge faster.

However, Lithium batteries contain toxic metals (nickel, manganese, cobalt), hence, have negative impact on environments. Even worse compared to fossil fuels in terms of productions or mining.

As reported by Prachi Patel in Daily Science (2022: New biodegradable, recyclable battery is made of crab shells) that scientists have created new material from crab shells and combines with zinc to replace Lithium.

The advantages of batteries from this new material are:

- lower cost

- live longer

- environmental friendly due to recyclable or biodegradable
