Why can’t phone companies or laptop companies make it so we can charge our devices almost instantaneously?
In: Technology
There’s a few reasons. The biggest is that charging a battery makes it get hot and you have to allow that heat to escape or else it will melt. The faster you charge it, the hotter it gets. So without having a giant fan on your phone, you can only charge it so fast before it will melt or blow up.
A second one is that there are limits to how fast a battery can charge and you just can’t go beyond that. Different types of batteries charge faster than others. There may one day be a battery that can be instantly charged, but we haven’t found the right design or combination of materials to do that.
