In: Chemistry

Most of nature works within the bounds of some kind of conservation – ie when you use something, it depletes, and in order to replenish it you must somehow reverse what you did. In that sense, the universe’s laws means we never have a “never ending” supply of something. Most of the energy we use as humanity comes from the sun (which will not last forever either – but it is going to last a long time) either directly or indirectly. Humans have just been getting smarter about how to convert (not create) the available energy to forms useful to us.

Li-on batteries cannot create energy. Once the energy stored in chemical bonds is used and converted to electrical energy, you need energy to restore the bonds (recharging) to make the battery useful again.

Because that would violate the laws of conservation of energy. You cannot create energy. You can change its state, but you cannot create it.
