Welcome to Windows Central.
It appears to be a battery problem. Check that the battery contacts are aligned are indeed in contact with the phone. Check out this
guide on how to open the back cover of your L521. After that, try charging your phone again.
If this doesn't resolve the issue, the battery might already be defective. You need to have it replaced either by buying a battery yourself or by going to a service center an inquiring about ordering a battery replacement - this should be covered by the 12-month warranty period for parts replacement, anyway, so it should be given to you for free.
