The IntelLiGent project answers to the need for general public acceptance of EVs, by facilitating the industrial deployment of next generation batteries allowing for an increased driving range, fast charging capabilities, low cost and increased safety. IntelLiGent will develop European generation 3b high voltage (>4.7 V) LIBs with increased energy density (>350-400 Wh/kg, 750-1000 Wh/l), charge acceptance (>2C) and cycle-life (>2000 deep cycles) compared to the state-of-the-art, while reducing cost (<100 €/kWh on pack level) and carbon footprint of the produced cells. The ambitious goals will be realized through optimized cells produced with; - High-voltage spinel LNMO cathode materials engineered to enhance stability and enable aqueous processing whilst exploring strategies to increase specific capacity beyond the theoretical maximum of standard LNMO - Energy efficient high-capacity stable Si-Gr anodes delivering 850 mAh/g -High-voltage electrolytes with innovative additives that form protective layers on the anode and the cathode - Self-mitigating and healing binders and separators minimize parasitic reactions and degradation - Novel open-source modelling tools and high-throughput screening will be employed to accelerate the development of environmentally benign materials with minimized use of critical raw materials -Optimized electrode design (=4.5 mAh/cm2) and cell design-based commercial-scale automotive cells (20 Ah) as well as battery modules (1 kWh) at TRL 6 From an industrial viewpoint, a prerequisite for succeeding is continuity in battery R&D&I projects and training/education of required staff, which IntelLiGent will foster by broad dissemination and exploitation of the project results across the battery value chain. The project will result in strengthening of the European battery value chain by developing European industries with leading edge technologies on battery materials, and allowing for accelerated roll-out of electrification for mobility

IntelLiGent项目通过促进下一代电池的工业部署来满足公众对电动汽车接受度的需求，从而增加行驶里程，快速充电能力，低成本和提高安全性。IntelLiGent将开发欧洲第3b代高电压（>4.7 V）LIB，与最先进的技术相比，其能量密度（>350-400 Wh/kg，750-1000 Wh/l），充电接受能力（>2C）和循环寿命（>2000次深循环）都有所提高，同时降低了成本（<100 €/kWh）和所生产电池的碳足迹。这些雄心勃勃的目标将通过优化生产的细胞来实现;- 高电压尖晶石LNMO阴极材料，旨在提高稳定性并实现水处理，同时探索将比容量提高到标准LNMO理论最大值以上的策略-高能效高容量稳定Si-Gr阳极，可提供850 mAh/g -高-具有创新添加剂的高电压电解质，可在阳极和阴极上形成保护层-自缓解和修复粘合剂和隔板可最大限度地减少寄生反应和降解-新型开源建模工具和高-将采用通量筛选，以加速开发环境友好型材料，同时最大限度地减少关键原材料的使用-优化电极设计（=4.5 mAh/cm 2）和基于电池设计的商业规模汽车电池（20 Ah）以及TRL 6的电池模块（1 kWh）从工业角度来看，成功的先决条件是电池研发与创新项目的连续性和所需员工的培训/教育，IntellLiGent将通过在整个电池价值链中广泛传播和利用项目成果来促进这一点。该项目将通过发展具有领先电池材料技术的欧洲产业，并加速推出移动电气化，从而加强欧洲电池价值链。
