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.

解决气候变化是21世纪人类最大的挑战。欧洲绿色协议宣布，欧洲致力于到2050年实现气候神经社会。为了减少运输，权力和行业的二氧化碳排放，欧洲必须紧急改变能源范式，转移到可再生能源。但是，可再生能源都是间歇性的，并且面临着存储挑战。二级电池具有高效的电源存储能力，并成为实现太阳能/风绿能量大规模应用的关键技术，从而支持欧洲能源系统的深层脱碳化。欧洲委员会估计，到2025年，电池行业的价值可以达到2500欧元。现有的电池系统仍然遭受低能密度和安全性问题的困扰。商用电池与电池2030+提出的高级电池之间存在巨大差距。采用新型电极材料被认为是开发下一代高性能电池的有前途的策略。但是，这些高容量电极材料在实际应用中提出了重大挑战（树突，体积变化和降解等），从而限制了其商业化前景。 Lesia将使用基于激光的制造和新兴的纳米级表征技术开发和构建具有电化学功能的生物启发的表面/接口。 Lesia将开发新的表面化学反应，并调节决定性的电化学界面工艺，从而应对下一代高级电池的高性能阳极和阴极的挑战。高级电池旨在提供450+ WH/kg的能量密度，5000 W/kg功率密度，5000多个循环和85欧元/千瓦时目标成本。 Lesia将使用基于尖端激光的表面/接口工程技术来创建高级电池开发的新范式。
