Tell me what is the difference between polymer lithium cells and polymer lithium batteries?

What's the difference between lithium polymer battery core and polymer lithium battery?

The battery composition is this: batteries and the protection board,

Batteries remove protection plate is the batteries.

Protection board, just as its name implies is to protect batteries, protective plate of the main functions are:

1, the overcharge protection: when you charge, reaching the highest voltage of the battery voltage (4.2 V), power protection board will automatically shut down, not in charge.

2, put the protection: when your battery power is about to run out of (a mobile phone is around 3.6 V) protection board will be closed, not in the discharge. Your instrument will automatically power off.

3, over current protection: when the battery discharge (use), protection board there will be one of the biggest limit current (different instrument requirement is different), when the discharge exceeds the current protection board will automatically shut down.

4, short circuit protection: when you accidentally short circuit batteries, protective plate will be automatically closed in milliseconds, in electricity, then across the electrodes is met a is ok.
