This is a newer type of Li-Ion battery. It uses a solid polymer electrolyte that looks like a plastic film. It contains a gelled electrolyte which is less susceptible to leaking and uses a bag type enclosure rather than a rigid metal case. This leads to a lighter and thinner battery and it is considered safer because the gelled electrolyte is less likely to leak. It is also more resistant to overcharge.
