电池3D打印专家Sakuu Corporationhas reached a new milestone in the development of its lithium metal battery, achieving a benchmark energy-density of 800 Wh/L.
According to the firm, the achievement is a significant step forwards on its roadmap to fully 3D printed solid-state batteries (SSB) capable of greater than 1,200 Wh/L by 2023, which would be far higher-performing than today’s market-leading lithium-ion batteries that function in the range of 500-700 Wh/L.
“The arrival of a safe, sustainable, and high-performance SSB, manufactured with a totally novel 3D printing method can solve critical supply chain and safety issues while moving beyond limitations of today’s lithium-ion batteries,” said Robert Bagheri, Founder and CEO of Sakuu.
“我们有望在2023年之前开发'圣杯'固态电池，而这一第一代基准是在路线图上的验证成就，可以显着更好的电池。”
3D打印下一代电池
Backed byMusashi Seimitsu，Sakuu生产了下一代SSB，并具有为电动汽车供电（EV）的潜力。该公司去年从Keracel从Keracel重新命名为Sakuu Corporation，此后不久发起了Sakuu AM Platform这是一种多边系统，能够将粘合剂射流和粉末床3D打印技术组合在一起，以处理同一部分层内的多种陶瓷和金属。
With this capability, Sakuu says the printer can deliver storage devices with improved interfacing and stronger ceramic layers than existing batteries, while integrating monolithically-layered cells that can be more easily produced at scale.
To further demonstrate the viability of its additive manufacturing technologies, the company has built apilot battery 3D printing facilitywhich is said to be able to initially produce up to 2.5 MWh of SSBs per anum before being expanded with a fleet of Sakuu AM Platforms this year. The systems will reportedly be able to produce up to 1 GWh of capacity each year.
十月，萨久完成了一场后续融资，这是total funding raised to $62 million。这些资金被汇集到启动其第一代SSB，并在未来的第二次迭代电池3D打印机上发行。
一个新的能量密度里程碑
在其第一代非印刷锂金属电池中实现800 WH/L的能量密度是Sakuu向前迈出的重要一步，它的目标是完全3D打印具有改进的能量存储的高性能SSB。值得注意的是，该公司声称其最新的基准测试比目前的市场商业可用电池更有希望。
除了其800 WH/L的成就外，该公司的锂金属电池还发现在200个周期后的高能量保留率为97％。一旦骑自行车完成，预计电池将在800个周期中记录80％的保留率。
The milestone is promising for the development of Sakuu’s second-generation fully 3D printed SSB, which is on track to begin being shipped in 2023. The company is anticipating another “substantial leap” in energy-density for its 3D printed battery, which is claimed to be the world’s first.
With twice the energy-density and 30% less weight than existing lithium-ion cells, the firm’s second-gen batteries could be deployed within energy storage, microreactors, and electronics applications.
如果该公司的路线图继续延续其当前轨迹，它认为其3D打印平台将在“ Gigafactory设置”中提供快速的大规模体积生产，这将满足全球对大规模，低成本的电池制造的需求。
Bagheri说：“我们正在创建一系列安全，可定制，低成本和高性能的电池，并以完全变革和可持续的方式制造它们，以满足全球大规模的需求。”
电池3D打印
Sakuu Corporationisn’t the only firm leveraging additive manufacturing to develop more efficient, high-performance batteries. While battery 3D printing remains a fledgling technology, there have been some other noteworthy developments in this area over the past year or so.
例如，2021年6月，瑞士采矿和投资公司黑石资源announced it was considering listing its Blackstone Technology division on the US stock exchange. The subsidiary says it is developing a 3D printing technology capable of producing高能量密度锂离子电池并准备进入连续细胞生产。
3D printer manufacturerPhotocentric同时，已经建立了专用电池研发部门to design its own energy-efficient storage devices containing 3D printed electrodes. The firm reportedly hopes leverage its technology to develop economical fuel cells for特斯拉的即将到来的Giga植物。
Elsewhere, the specialist 3D printing materials specialist6k打开了一个新的2500万美元的设施,致力于吗identifyingsustainable energy storage alternativesin order to find the optimal source material for battery production.
