Searching for new cheap encapsulating materials to decrease the solubility of organic small molecules as the cathode materials in electrolytes and improve the performance of organic lithium-ion batteries (LIBs) is very important and highly desirable. In this research, we found that a novel cheap biomass carbon (named as PPL), prepared by pyrolyzing calyxes of Physalis Peruviana L, can efficiently encapsulate calix[4]quinone to form composites, which can be used as cathodes in LIBs. The initial discharge capacity of the as-fabricated battery was 437 mAh g and could maintain 228 mAh g after 100 cycles. Even at 1 C, the discharge capacity was still 217 mAh g .
寻找新的廉价包封材料来降低有机小分子作为电解质中阴极材料的溶解度，并提高有机锂离子电池（LIB）的性能是非常重要和非常需要的。在这项研究中，我们发现一种新型的廉价生物质碳（名为 PPL），由酸浆萼片热解制得，可以有效地封装杯[4]芳烃醌形成复合材料，可作为 LIB 的阴极。所制备电池的初始放电容量为 437 mAh·g，经过 100 次循环后可保持 228 mAh·g。即使在 1 C 下，放电容量仍为 217 mAh·g。
