Herein we demonstrate the use of very high surface area 3D carbon cuboids synthesized from a metal-organic framework (MOF) as a cathode material with Li4Ti5O12 as the anode for high performance Li-HECs. The energy density of the cell is similar to 65 W h kg(-1) which is significantly higher than that achievable with commercially available activated carbon (similar to 36 W h kg(-1)) and a symmetric supercapacitor based on the same MOF-derived carbon (MOF-DC similar to 20 W h kg(-1)). The MOF-DC/Li4Ti5O12 Li-HEC assembly also shows good cyclic performance with similar to 82% of the initial value (similar to 25 W h kg(-1)) retained after 10 000 galvanostatic cycles under high rate cyclic conditions. This result clearly indicates that MOF-DC is a very promising candidate for future P-HEVs in a Li-HEC configuration.</p>1 aBanerjee, Abhik1 aUpadhyay, Kush, Kumar1 aPuthusseri, Dhanya1 aAravindan, Vanchiappan1 aMadhavi, Srinivasan1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/mof-derived-crumpled-sheet-assembled-perforated-carbon-cuboids-highly-effective-cathode-0
