A separator for a high energy rechargeable lithium batterynincluding a ceramic composite layer and anpolymeric microporous layer. The ceramic layers includes anmixture of inorganic particles and a matrix material. Thenceramic layer is adapted, at least, to block dendrite growth andnto prevent electronic shorting. The polymeric layer is adapted,nat least, to block ionic flow between the anode and the cathodenin the event of thermal runaway. |
