How does a battery convert chemical energy to electrical energy?

Batteries store chemical energy and convert it to electrical energy through reactions between two electrodes – the anode and cathode. Charge-carrying particles, known as ions, are transferred via the middle component of the battery, known as an electrolyte. The most common type of batteries used in household products are lithium-ion batteries.

Why do we need a new battery chemistry?

These should have more energy and performance, and be manufactured on a sustainable material basis. They should also be safer and more cost-effective and should already consider end-of-life aspects and recycling in the design. Therefore, it is necessary to accelerate the further development of new and improved battery chemistries and cells.

Why is energy chemical engineering important for battery research?

Moreover, advancements in energy chemical engineering provide strong support for battery research, including proof-of-concept prototype batteries, pilot production, and so on. Fig. 1. Schematics of Li-ion, Li–S, and Li–O 2 batteries based on non-aqueous liquid electrolytes.

What makes innovation in battery chemistry possible?
