Lithium‐ion capacitors (LICs) optimize energy density and power capability of lithium‐ion batteries (LIBs) and electric double layer capacitors (EDLCs). The most promising LICs are those, called dual‐carbon LICs, using the LIB carbonaceous negative electrode and EDLC activated carbon positive electrode due to the low lithiation‐delithiation potential of carbonaceous materials and the excellent stability of activated carbon at high potentials. However, a pre‐lithiation process is required to enable such LICs because both the carbonaceous materials used do not contain Li⁺ ions. In this mini‐review, the principle and materials of the dual‐carbon LICs are outlined, and the key technologies are critically assessed.

双碳锂离子电容器：原理，材料和技术

锂离子电容器（LIC）可优化锂离子电池（LIB）和双层电子电容器（EDLC）的能量密度和功率容量。最有前途的LIC是使用LIB碳质负极和EDLC活性炭正电极的双碳LIC，这是因为碳质材料的低锂化-脱锂电位和高电位下活性炭的出色稳定性。然而，由于使用的两种碳质材料均不含Li ⁺离子，因此需要进行预锂化工艺以实现此类LIC 。在此小型审查中，概述了双碳LIC的原理和材料，并对关键技术进行了严格评估。
