Welcome to AAC!

Your charger may be merely a 5V source, with the all-important charge/discharge control being done by circuitry in the tablet.
Looking at the battery, I'd guess the charge/discharge control circuitry has a fault which caused over-charging of the battery.

If you find the correct specs (Voltage and Current) and meet the requirements of the power source, you should be able to tie in an external power supply by connecting directly to the leads that are currently attached to the battery.

That certainly looks like a pouch encapsulated lithium battery - had that been a cylindrical steel cased cell, the event would probably have involved a bit of violence!

The charge control circuit has obviously developed a fault, and bypassing what's left of the charge control won't be any better.

Don't take risks with lithium cells - if overcharged, they can vent with flaming gas. The steel cased type can build up a head of steam and burst with considerable violence!
