Abstract:
Provided herein are a variety of porous separator materials, particularly those prepared by gas-assisted electrospray and electrospinning processes.

Claim (Index 15):
A lithium ion battery comprising a positive electrode, a negative electrode, and a separator, the separator comprising a thin film porous membrane,\n the battery separator comprising a polymer and a continuous ceramic coating; the battery separator comprising a first surface and a second surface, the continuous ceramic coating coating at least 50% of the first surface of the battery separator by area (excluding pores), and the average thickness of the continuous ceramic coating being less than 15% of the average thickness of the battery separator; the separator comprising about 50 wt. % to about 80 wt. % polymer, and about 20 wt. % to about 50 wt. % ceramic; the battery separator or the porous membrane comprising a core, the core being configured between the surfaces thereof, the core comprising a continuous ceramic core matrix; the battery separator shrinking less than 2% in both the longitudinal and transverse directions upon heating to at least 200 C; the capacity of the battery at a charge rate of at least 2 C being at least 80% of the capacity at a charge rate of 1 C or less; and the battery separator having a porosity of about 10% to about 70% and an average thickness of about 1 micron to about 25 micron.
