Organic redox active molecules are the promising electrode materials for the Lithium‐ion batteries (LIBs). The semiconducting nature and morphology of these materials provide more efficient charge transport. Hence, it is very important to perform systematic study of such molecules. Herein, we proposed single step synthesis of the benzoic naphthalene diimide (Benzoic‐NTCDI) by the reaction of 1, 4, 5, 8‐ naphthalene tetracarboxylic dianhydride with 4‐amino benzoic acid in presence of hydrated zinc acetate as a catalyst. As‐synthesized benzoic NTCDI is characterised by using different characterization techniques. The morphological study clearly demonstrate hierarchical porous assembly of 3–5 micron comprised with nanopetals of thickness 5–10 nm. In this hierarchical nanostructure, the nanopetals are originated from the centre and confer voids between the layers of petals. This creates porosity throughout the hierarchical assembly. Considering such unique porous nanostructure and good conductivity of the Benzoic‐NTCDI (1.19×10⁻⁵ S/m), it has been used as a cathode for LIB.The Li‐cell was fabricated using Benzoic‐NTCDI as a cathode which demonstrated the reversible capacity of 102 mAhg⁻¹ at 0.05 C rate. Moreover, the capacity of 91 mAhg⁻¹ is retained at current density of 0.1 C exhibiting good rate capability after 24 cycles. The Li‐ion transport has been accelerated is ascribed to the porous hierarchical nanostructure. The potential of one of the heterocyclic molecule with hierarchical nanostructure as a cathode for lithium ion batteries (LIBs) has been demonstrated for the first time

锂离子电池的分层纳米结构苯甲酸四羧酸二酰亚胺有机阴极

有机氧化还原活性分子是锂离子电池（LIB）的有前途的电极材料。这些材料的半导体性质和形态可提供更有效的电荷传输。因此，对此类分子进行系统研究非常重要。在此，我们提出了在水合乙酸锌作为催化剂的情况下，通过1、4、5、8-萘四甲酸二酐与4-氨基苯甲酸的反应，一步合成苯甲酸萘二酰亚胺（Benzoic-NTCDI）。合成的苯甲酸NTCDI通过使用不同的表征技术来表征。形态学研究清楚地表明了3–5微米的分层多孔组件，其厚度为5–10 nm的纳米花瓣。在这种分层的纳米结构中，纳米花瓣起源于中心，并在花瓣层之间赋予空隙。这会在整个分层装配中产生孔隙。考虑到这种独特的多孔纳米结构和良好的Benzoic-NTCDI电导率（1.19×10^-5 S / m），它已被用作LIB的阴极.Li-电池是使用Benzoic-NTCDI作为阴极制造的，在0.05 C的速率下显示出102 mAhg ^-1的可逆容量。此外，在0.1 C的电流密度下保持91 mAhg ^-1的容量，在24个循环后表现出良好的速率能力。锂离子的传输加速归因于多孔的分层纳米结构。首次证明具有分层纳米结构的杂环分子之一作为锂离子电池（LIB）阴极的潜力
