Why can’t phone companies or laptop companies make it so we can charge our devices almost instantaneously?

In: Technology

Answer 1

Charging a battery is a chemical process where chemical reactions are reversed by the addition of energy (the charger). Such processes takes time. In contrast to a capacitor, which can be charged instantly, the energy is stored via a physical process i.e the electrons are stored at or within the surface without changing the chemistry. The downside is that they will discharge equally fast.
