Hi, I have a question regarding li-ion battery charging.

Can I charge the battery by connecting the battery to a AC/DC rectifier? (that is connected to the mains)

Phone chargers convert Line AC to low-voltage DC in a safe way. Get a retired DC-output phone charger to get the DC voltage.

Li-ion s are fussy to charge properly. Read this article. You need a proper charge-controller circuit. This is usually handled by the microprocessor inside the phone. To build a stand-alone one is a complex project, much beyond your capabilities.
