Introduction: Solid-state batteries are a widely recognized next-generation battery technology. The goal is to solve newenergyThe car’s need for safety and long battery life. Because of the advantages of safety and energy density, solid-state batteries are very suitable for consumption,aviationaerospace, Mobile and many other applications.along with3D printingWith the expansion of technology to the energy field, new solid-state battery manufacturing technology has gradually changed from concept to reality.

Automated multi-process additive manufacturing (AM) leader Sakuu Corporation (formerly KeraCel Inc.) announced on July 28, 2021 that it has developed a 3Ah lithium solid-state battery (SSB) with performance equal to or better than current ones lithium battery. Sakuú plans to provide battery samples to partners at the end of the third and fourth quarters of 2021.

Sakuú has been developing the first-generation SSB battery technology and its flagship additive manufacturing platform. The platform is said to use a multi-material adhesive jet process and will be put into commercial use by the end of 2021.The first-generation battery includes 30 sub-cells, using lithium metal andceramicsClapboard.In addition, the battery design uses the current industrystandardCathode materials (may be used in the future to support higher voltage cathode materials), can generate up to 25% of the energy.

Sakuú CEO and founder Robert Bagheri said that the company developed the first generation of SSB to prove that battery technology is advanced in Sakuú 1000.3D printingThe feasibility of the platform. He also added that in the past year, the company has increased battery energy capacity by 100 times and volumetric energy efficiency by more than 12 times, and plans to start mass production of batteries in early 2022 to meet the needs of strategic partners.
Solid state battery3D printingNow it has become the vane for the development of additive manufacturing in the energy field, and companies are striving to capture this “highland”. In May 2021,Sakuú announced a new industrial-grade 3D electric car battery printer, High-profile entry into the energy market. A month later,Three more patents were published to further improve the technology.And its industry competitor, Blackstone Technology GmbHIn January 2021, it declared a breakthrough in the field of solid-state batteriesAnd inA pouch battery was shown in April.It is reported that this company is still in JuneAppointed a new marketing officer to actively promote listing in the United States.
