The use of 3D printing technology to produce lithium-ion and sodium-ion new energy vehicle batteries has the advantages of significantly improved battery energy density, easy access to raw materials, reduced raw material procurement costs and battery costs, mass production, and lightweight.
In the context of global energy transition, and in today's advocacy of green energy, batteries as a power source play an important role in supporting the realization of China's dual carbon goals. Using 3D printing technology to produce lithium-ion and sodium-ion new energy vehicle batteries has the advantages of significantly improved battery energy density, easy availability of raw materials, reduced raw material procurement costs and battery costs, mass production, and lightweight.

At present, the traditional battery cells on the market are large and heavy, and they are not optimized for automotive applications. In addition, due to the increasing market demand for raw materials such as lithium and cobalt, the cost of batteries continues to increase. On the one hand, the government Departments and relevant associations are urging enterprises to strengthen self-discipline, promote cooperation between upstream and downstream enterprises, and "cool down" battery costs.

On the other hand, 3D printed batteries have once again attracted the attention of the industry. In fact, the advantages of 3D printing batteries are obvious, namely, easy availability of raw materials, environmentally friendly manufacturing processes, more economical manufacturing processes, and higher battery safety. Compared with traditionally manufactured batteries, 3D printing-additive manufacturing technology has a great impact on battery electrodes. The structure has a great impact, making the energy density higher and enabling mass production.

So, in the field of 3D printing batteries, which companies at home and abroad have entered the market, and what is the development of the industry?

Sakuu Corporation has been committed to the development and promotion of 3D printed solid-state batteries, and recently announced a new breakthrough in the production of ceramic solid-state lithium batteries. Later, it cooperated with Japanese auto parts manufacturers to accelerate the development of 3D printed solid-state batteries. On July 28, 2021, the company announced that it had developed a 3Ah lithium solid-state battery (SSB) with performance equal to or better than current lithium batteries.

On August 22 of the same year, the production of 3D printed solid-state batteries began. According to reports, the pilot production line that the company has started to build will be completed by the end of 2021. After it is put into operation, it will be able to produce solid-state batteries of up to 2.5 MWh per year, and its additive manufacturing technology combines powder bed and spray material deposition technology. Monolithic layers and perfect interfaces to produce high energy density solid-state batteries (SSBs).

And Blackstone Resources from Switzerland announced a series of landmark achievements in 3D printing lithium-ion solid-state batteries. It is understood that the company's first-phase factory production capacity will reach 0.5GWh per year, and by 2025, the annual production capacity of cells will reach 3GWh. In March 2022, the company announced that it expects to commercialize 3D-printed sodium-ion batteries as early as 2025.

On September 15, 2020, 3D printer and material manufacturer photocentric announced the establishment of a 3D printing battery research department, focusing on the development of environmentally friendly 3D printing batteries, and said it would continue to increase investment to optimize the application of 3D printing fuel cells in automobiles. The company is said to have actually developed a self-contained 3D printed battery system, and the 3D printer relies on visible light rather than UV light to cure the photopolymer parts, meaning the machine uses less energy to operate.

Looking at domestic enterprises, on May 11, 2021, Changchun Jiaotong University High-energy Technology Co., Ltd. (hereinafter referred to as Jiaoda High-energy Technology), a provider of digital 3D printing solutions for power batteries, announced that it has obtained a seed round of financing of millions of RMB. It is reported that the company's 3D printing battery technology has significantly improved the safety performance of power batteries, has the potential to increase energy density by 80% and reduce manufacturing costs by 50%, and has huge technical advantages and commercial value.
