Core Viewpoint - The research team from Southeast University has developed a groundbreaking bio-inspired self-generating and energy-storing concrete, which aims to transform the construction industry's high energy consumption and carbon emissions into a comprehensive energy solution [1][2]. Group 1: Energy Consumption and Emissions - Currently, the construction process in China accounts for 45% of the national energy consumption and over 50% of carbon emissions [1]. - Traditional photovoltaic power generation is limited by weather conditions and high storage costs [1]. Group 2: Innovative Materials - The team has created two types of self-generating cement-based supermaterials: N-type thermoelectric cement and P-type thermoelectric cement, which can convert temperature differences into electricity [1]. - The N-type thermoelectric cement has a Seebeck coefficient of -40.5 mV/K, approximately ten times higher than the best traditional thermoelectric materials [1]. - The P-type thermoelectric cement has a power factor (PF) 51 times and a ZT value 42 times higher than traditional materials [1]. Group 3: Mechanical Properties and Applications - The self-generating cement-based supermaterial can continuously generate electricity as long as there is a temperature difference, addressing the supply gap in clean energy [1]. - The compressive strength of the new materials is enhanced by 60%, and toughness is increased nearly tenfold, overcoming the mechanical performance limitations of traditional thermoelectric materials [1]. Group 4: Energy Storage Capabilities - The team has also developed a self-storing cement-based supercapacitor that maintains high strength while increasing ionic conductivity by six orders of magnitude [2]. - After 20,000 charge-discharge cycles, the supercapacitor retains 95% of its initial specific capacitance, matching the lifespan of the building [2]. Group 5: Environmental Impact and Future Potential - The innovations in cement materials are reshaping the traditional view of building materials from merely structural to energy-generating entities, providing critical technological support for achieving carbon neutrality goals [2]. - These advancements open up limitless possibilities for a green and intelligent lifestyle for humanity [2].

一块水泥砖能给手机、汽车充电？是真的！5月9日，记者从东南大学了解到，由中国工程院院士、东南 大学教授缪昌文和材料科学与工程学院教授周扬团队研发的仿生自发电-储能混凝土正式亮相。这项全 球首创的技术直击建筑行业高能耗痛点，将水泥从"能源消耗者"变为"能源综合体"，实现自发电与自储 能的双重突破。 历时4年研发 让水泥可发电、可储能 "建筑行业的碳排放占社会碳排放总量的50%，能耗占比也超过45%以上。"周扬告诉记者，以太阳能光 伏为代表的清洁能源技术，虽然可以有效地降低建筑碳排放，实现碳达峰、碳中和目标，但是受天气制 约大、储能成本高昂等短板也愈发凸显。为了解决这些问题，周扬团队依托重大基础设施工程材料全国 重点实验室，在国家自然科学基金首批原创-探索项目的资助下，历时4年研发了仿生自发电-储能混凝 土，涵盖自发电水泥基超材料、自储电水泥基超级电容器两大技术模块，让混凝土这种世界上用量最大 的建筑材料变为能源的生产者、储存者。 记者在现场看到，团队成员将4块自发电水泥串联在一起后，产生了3.1伏的电压，LED灯泡随即亮了起 来。水泥为什么可以自发电？周扬向记者解释到："有温差，自发电水泥材料就可以将热能转化为 ...
