I know that in a normal battery once the electrons have made their way from the anode to the cathode the battery dies, but rechargeable batteries are able to sort of reset the battery once it’s been put on charge.
Every time I watch a YouTube video on rechargeable batteries all they say is “We do this by forcing the electrons back to the anode” without explaining exactly how that works and its driving me up the goddamn wall.

Its essentially a two way chemichal reaction: one way the chemicals used, like lithium .
discharge electrons that will power electronics. Then when electrons are forced back by charging, the chemichal reaction reverses as these electrons disrupt the discharged state, and force the anode and cathode to sort of recombine. Its not perfect system, so perfomance drops, as not all chemichals return to their origional state.
Non rechargeable batteries have chemicals that do not reform when forced by electric current and electrons rushong back. So they are single use. The rechargeable battiries thus, are known to also loose 20-30% of their origional capacity within the year. Due to the cycles of discharging and rechaging issues like chemical degradation, imperfect recombination in recharge, the list can go on and on. There are many issues that cause this perfomance and capacity drop.
