Thermal management systems for high energy density batteries, particularly arrays of such batteries, and methods of making and using thereof are described herein. The system includes one or more thermal conductive microfibrous media with one or more phase change materials dispersed within the microfibrous media and one or more active cooling structures. Energy storage packs or arrays which contain a plurality of energy storage cells and the thermal management system are also described. Further described are thermal or infrared shielding blankets or barriers comprising one or more thermal conductive microfibrous media comprising one or more phase change materials dispersed within the microfibrous media. 1. A thermal management system comprising one or more thermal conductive microfibrous media comprising one or more phase change materials dispersed within the microfibrous media and one or more active cooling structures.2. The system of claim 1 , wherein the microfibrous media comprise sintered metal fibers selected from the group consisting of copper claim 1 , nickel claim 1 , aluminum claim 1 , steel claim 1 , stainless steel claim 1 , silver claim 1 , gold claim 1 , and alloys claim 1 , and combinations thereof.3. The system of claim 1 , wherein the microfibrous media comprise wet-lay sheets claim 1 , bonded threads or yarns claim 1 , and/or woven sheets of carbon/graphite claim 1 , natural claim 1 , ceramic claim 1 , or polymer fibers and various single wall and multi-wall nanotubes claim 1 , and combinations thereof.4. The system of claim 1 , wherein the microfibrous media comprise thermal conductive fibrous media filled with fine micronsized or nano-sized fibers claim 1 , and media partially filled with fine micronsized or nano-sized fibers concentrated near the contacting surfaces for heat transfer.5. The system of claim 1 , wherein the diameter of the metal fibers is from about 0.5 microns to about 250 microns and the diameter of the carbon fibers is from ...
