The 51st International Exhibition of Inventions of Geneva was held in March 2026 in Geneva, Switzerland. This year’s exhibition brought together more than 1,000 inventions from 35 countries and regions, with entries evaluated by an independent international jury.
第51届日内瓦国际发明展于2026年3月在瑞士日内瓦举行。本届展会汇聚来自35个国家和地区的1000多项发明，并由独立国际评审团评选。
The Gold Medal with Jury Congratulations is a high-level distinction granted special recognition by the jury and awarded in relatively limited numbers. It reflects the jury’s strong recognition of the invention’s innovation value and potential for practical translation. The LETS team received this honor for the invention “Electrolyte and its Use in Lithium-Based Batteries.” In addition, our collaborative project “HarvSolar: Highly Efficient Integrated All-Perovskite Photovoltaic-Battery System for Portable Electronics” was awarded a Silver Medal.
“评审团特别嘉许金奖”是从金奖项目中进一步遴选产生的特别荣誉，代表评审团对发明创新性与应用潜力的高度认可。LETS团队凭借“用于锂电池的电解液及其应用”（Electrolyte and its use in lithium-based battery）获得这一荣誉。同时，合作课题”用于便携式电子产品的高效集成式全钙钛矿光伏-电池系统“（HarvSolar）荣获银奖。
Both award-winning projects were carried out by PhD students under the supervision of the PIs and were presented and defended before the jury at the exhibition. The related research findings have been published in Advanced Science and Nature Communications, respectively, reflecting the team’s continued efforts in electrolyte design, interfacial regulation, and integrated energy-storage systems.
两个获奖项目均由课题组博士生在导师指导下完成，并在展会现场进行了答辩与展示。相关研究成果已分别发表于 Advanced Science 和 Nature Communications，体现了团队在电解液设计、界面调控与集成能源系统方向的持续积累。
The electrolyte project addresses critical interfacial stability challenges in high-energy-density lithium batteries. Through synergistic tuning of cation–anion solvation structures to accelerate ion transport kinetics and engineer stable interfacial layers, the electrolyte enables exceptional electrochemical performance across a wide temperature range (−60°C to 45°C) and at high voltages up to 4.6 V, meeting key targets for practical deployment in demanding applications with significantly improved cycle stability and safety.
电解液项目聚焦锂电池在高能量密度和复杂工况应用中的关键界面稳定性问题，通过协同调控阳离子-阴离子的溶剂化结构加速离子传输动力学并构筑稳定界面层，使电池在-60℃低温到45℃高温的宽温域及4.6V高电压条件下表现出优异的电化学性能，显著提升循环稳定性与安全性能。
The HarvSolar proposes a shared-material integration strategy, in which the same functional molecule, ethyl viologen diiodide (EVI₂), is used to modify both the perovskite solar-cell interface and the battery cathode material, achieving “one material, benefits at both ends.” The integrated photovoltaic-battery device achieved an overall energy conversion efficiency of 18.54%, with a flexible-device version reaching 17.62%, and demonstrated continuous 24-hour power supply for a wearable glucose-monitoring device.
HarvSolar通过同一种功能分子（乙基紫罗碱二碘化物，EVI₂）同时修饰钙钛矿太阳能电池界面与电池正极材料，实现”一种材料、两端受益”。集成后的光伏-电池一体化器件整体能量转换效率达18.54%，柔性器件版本为17.62%，并已实现为可穿戴血糖监测设备连续供电24小时的演示验证。
This exhibition provided an important opportunity for our PhD students to step beyond the laboratory, present their research on an international stage, and respond directly to questions from the jury. It also served as a focused showcase and validation of the team’s sustained efforts in battery materials, electrolytes, and integrated energy-storage systems.
此次参展是课题组博士生走出实验室、在国际舞台上直接面对评审团答辩的经历，也是团队近年来在电池材料与集成储能系统方向持续积累的一次集中检验。
