The interfacial chemistry of solid electrolyte interphases(SEI)on lithium(Li)electrode is directly determined by the structural chemistry of the electric double layer(EDL)at the ***,a strategy for regulating the structural chemistry of EDL via the introduction of intermolecular hydrogen bonds has been proposed(p-hydroxybenzoic acid(pHA)is selected as proof-of-concept).According to the molecular dynamics(MD)simulation and density functional theory(DFT)calculation results,the existence of hydrogen bonds realizes the anion structural rearrangement in the EDL,reduces the lowest unoccupied molecular orbital(LUMO)energy level of anions in the EDL,and the number of free solvent molecules,which promotes the formation of inorganic species-enriched SEI and eventually achieves the dendrite-free Li *** on this strategy,Li‖Cu cells can stably run over 185 cycles with an accumulated active Li loss of only 2.27 mAh cm^(-2),and the long-term cycle stability of Li‖Li cells is increased to 1200 *** addition,the full cell pairing with the commercial LiFePO_(4)(LFP)cathodes exhibits stable cycling performance at 1C,with a capacity retention close to 90%after 200 cycles.

农产品加工企业创新是促进乡村产业振兴、推动农业高质量发展的重要驱动力。本文从农地“三权分置”视角,分析中国农地制度改革促进农产品加工企业创新与竞争的理论逻辑,并以农地“三权分置”政策实施为准自然实验,采用倍差法和上市公司数据进行实证检验。研究发现:农地“三权分置”对农产品加工企业的技术创新具有显著促进作用,且对弱垄断势力企业的促进效应更大,这些结论在排除行业发展趋势、全国性政策影响、控制非平行趋势后仍稳健。机制分析表明,农地“三权分置”通过降低农产品加工企业成本促进了技术创新。此外,农地“三权分置”对林产品加工企业创新的促进作用显著大于种植加工与养殖加工企业。研究展现了农地“三权分置”在推动农产品加工企业创新与竞争中的重要作用,为理解中国农地制度改革的经济效应提供了经验证据。
