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

AM4BAT将开发创新的组件材料，并通过具有成本竞争力且可持续的Vat光聚合3D打印来组装无阳极全固态电池（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。这将通过开发以下材料来实现：i) 具有卓越能量的单晶 NMC811，ii) 无钴 LNMO 和更高电压的 AM4BAT 变体，iii) 具有 0.5 至 5μm 和 50-100 nm 不同尺寸的掺杂 LLZO，以提高 HSE 中的负载量，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加工优化。然后，AM4BAT 将通过达到 TRL5 的 3-Ah 软包电池验证该技术，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。确定的利益相关者群体以及其他研究计划将积极参与，以确保 AM4BAT 结果的传播和更广泛用户的接受。凭借基于尖端 3D 打印 ASSB 的雄心勃勃的概念以及涉及从材料供应商到 OEM 的整个价值链的强大联盟，AM4BAT 旨在克服工作计划中指定的 Gen 4b 技术的剩余技术障碍，并实现电池行业紧迫的短期需求：使 Gen 4b 电池成为 2025 年以后的可行技术。从长远来看，AM4BAT 的成果将有助于创建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并加速能源转型。

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.
