Laser Engineered Surfaces/Interfaces for Advanced Batteries

应对气候变化是21世纪人类面临的最大挑战。《欧洲绿色协议》宣布，欧洲致力于到2050年实现气候神经社会。为了减少交通、电力和工业部门的二氧化碳排放，欧洲必须紧急改变能源模式，转向可再生能源。然而，可再生能源都是间歇性的，并且面临着存储方面的挑战。二次电池提供了高效的电能存储能力，成为实现太阳能/风能绿色能源大规模应用的关键技术，从而支持欧洲能源系统的深度脱碳。欧盟委员会估计，到2025年，电池产业的价值可达到2500亿欧元。现有的电池系统仍然存在能量密度低和安全问题。商用电池与BATTERY2030+提出的先进电池存在巨大差距。采用新型电极材料是开发新一代高性能电池的重要途径。然而，这些高容量电极材料在实际应用中提出了重大挑战（枝晶，体积变化和降解等），这限制了它们的商业化前景。LESIA将使用基于激光的制造和新兴的纳米级表征技术，为电池组件开发和构建具有电化学功能的仿生表面/界面。LESIA将开发新的表面化学，并调节决定性的电化学界面过程，从而解决下一代先进电池高性能阳极和阴极的挑战。这些先进电池的设计目标是提供450+ Wh/kg的能量密度、5000+ W/kg的功率密度、5000+次循环和85欧元/kWh的目标成本。LESIA将通过使用尖端的基于激光的表面/界面工程技术，创造先进电池开发的新范例。

Addressing climate change is humanity's greatest challenge in the 21st century. The European Green Deal has declared that Europe is committed to realizing a climate-neural society by 2050. To reduce carbon dioxide emissions from transport, power, and industry sectors, Europe must urgently change the energy paradigm, shifting to renewables. However, renewables are all intermittent, and facing the storage challenge. Secondary batteries offer highly efficient electrical energy storage capability, and become the key technology to achieve the large-scale application of solar/wind green energy and thus support the deep decarbonization of European energy system. European Commission estimated that the value of battery industry can reach 250 Euros billion by 2025. Existing battery systems still suffer from low energy density and safety issues. There is huge gap between commercial batteries and advanced battery proposed by BATTERY2030+. Employing novel electrode materials are considered as promising strategies to develop next generation high performance batteries. However, these high capacity electrode materials raise significant challenges (dendrite, volume change, and degradation etc.) in practical application, which limit their commercialization prospects. LESIA will develop and construct bio inspired surfaces/interfaces with electrochemical functionalities for the components of batteries using laser-based fabrication and emerging nanoscale characterisation techniques. LESIA will develop new surficial chemistry, and regulate the decisive electrochemical interfacial processes, and thus address the challenges of the high performance anodes and cathodes for next generation advanced batteries. The advanced batteries are designed to deliver 450+ Wh/kg energy density, 5000+ W/kg power density, 5000+ cycles and 85 Euros/kWh target cost. LESIA will create new paradigm of advanced battery development by using cutting edge laser-based surface/interface engineering technologies.
