摘要：
Capacitive deionization (CDI) is an emerging technology to supply deionized water as liquid coolant for the thermal management in microelectronics. Graphene has been demonstrated as a promising candidate for CDI electrode. However, the performance of current graphene-based CD! is far below expectation due to the limited specific surface area (SSA) and electrical conductivity of the chemically reduced graphene. Here we presented a KOH-activated graphene that has ultrahigh SSA of 3513 m(2)/g and electrical conductivity of 104 S/m. With improved materials properties, an ultrahigh electrosorption capacity of 11.86 mg/g and a significant adsorption rate of 20 min are achieved. (C) 2014 Elsevier Ltd. All rights reserved.
