AM4BAT: Gen. 4b Solid State Li-ion battery by additive manufacturing

AM4 BAT将开发创新的组件材料，并通过具有成本竞争力和可持续性的增值光聚合3D打印制造无阳极全固态电池（ASSB）。目标是为电动汽车应用提供能量密度为400 Wh/kg和1000 Wh/L的高性能电池。这将通过开发材料来实现，所述材料包括i）具有优异上级能量的单晶NMC 811，ii）用于功率AM4 BAT变体的LNMO无Co和更高电压，iii）具有0.5至5μm和50-100 nm的不同尺寸的掺杂LLZO，用于HSE中的更高负载，以及iv）新型丙烯酸、纳米纤维素、可持续光固化聚合物。这些材料将通过增材制造进行优化处理。AM4 BAT将通过达到TRL 5的3 Ah袋式电池验证该技术，并将进行可制造性评估，全面的可持续性评估和回收研究，以支持客户的采用。已确定的利益攸关方团体以及其他研究举措将积极参与，以确保AM4 BAT成果的传播和更广泛的用户接受。凭借其基于尖端3D打印ASSB的雄心勃勃的概念和涉及从材料供应商到OEM的整个价值链的强大联盟，AM4 BAT旨在克服工作计划中规定的Gen 4 b技术的剩余技术障碍，并实现电池行业的紧迫短期需求：使Gen 4 b电池成为2025年以后的可行技术。从长远来看，AM4 BAT的成果将有助于创建一个可持续的欧洲电池制造价值链，帮助欧盟在电动汽车的推出和加速能源转型方面取得成功。

AM4BAT will develop innovative component materials and assemble an anode-free all-solid-state battery (ASSB) manufactured by a cost-competitive and sustainable vat photopolymerization 3D printing. The objective is to reach a high-performance battery the energy density of 400 Wh/kg and 1000 Wh/L for electric vehicles applications. This will be achieved by developing materials including i) single crystal NMC811 with superior energy, ii) LNMO Co-free and higher voltage for power AM4BAT variant, iii) dopped LLZO with different size from 0.5 to 5µm and 50-100 nm for higher loading in the HSE, and iv) novel acrylic, nanocellulose, sustainable photocurable polymer. The materials will be optimized for their processing by additive manufacturing. AM4BAT will then validate the technology via 3-Ah pouch cells reaching TRL5, and will carry out an evaluation of manufacturability, a full sustainability assessment and a recycling study to support customers’ uptake. Identified stakeholder groups as well as other research initiatives will be actively involved to ensure dissemination of AM4BAT results and broader users’ acceptance. With its ambitious concept based on cutting-edge 3D printed ASSB and a strong consortium involving the whole value chain from material providers to an OEM, AM4BAT aims to overcome the remaining technological obstacles of the Gen 4b technology as specified in the work programme and accomplish the urgent shorter-term needs of the battery industry: to make Gen 4b batteries a viable technology beyond 2025. On longer term, the AM4BAT outcomes will contribute to the creation of a sustainable European battery manufacturing value chain helping the EU to succeed in the electric mobility roll-out and accelerate the energy transition.
