Sakuu teams for solid state battery electrodes

Business news |
By Nick Flaherty


3D printed battery startup Sakuu has signed a deal with LiCAP Technologies for the supply of electrode materials for solid state batteries.

The long-term deal accelerates Sakuu’s development of a high-throughput additive manufactured solid state battery production line and follows a deal with NGK in Japan for other materials for the solid state batteries..

Sakuu plans to license LiCAP’s proprietary dry electrode process technology, and LiCAP will also supply high-performance electrodes for Sakuu’s anticipated at-scale solid-state battery production needs.

LiCAP’s patented Activated Dry Electrode process uses a blend of battery materials with a proprietary compound to activate the formulation. The mixture is then fed into proprietary equipment that produces a stand-alone electrode film that can be laminated on a current collector foil using high-speed production equipment.

This means there is no need for drying ovens, or solvent recovery systems and so is more suited to 3D printing and additive manufacturing. Any trimmings or excess electrode film can also be 100% recycled, eliminating the costly waste removal operations.

The two companies will also work on Sakuu’s next generation ultra-high energy density batteries that can be printed in custom shapes and sizes and are anticipated to be 50% smaller and 30% lighter compared to established roll-to-roll manufacturing processes

“We are pleased to have established this relationship with LiCAP towards introducing and commercializing sustainably printed solid-state batteries,” said Arwed Niestroj, SVP of Customer Enablement at Sakuu.

“LiCAP’s electrodes can substantially increase energy and power performance of Sakuu’s battery cells. Its innovative and cost-effective electrode technology can further promote performance, cost- savings, and product recyclability across our planned AM solid-state battery line.”

 “We are extremely impressed with Sakuu’s AM battery manufacturing concept and see many synergies with our sustainable and cost-effective electrode platform. Sharing sustainability and performance goals with Sakuu will ensure long-term mutual growth,” said Linda Zhong, President of LiCAP Technologies.

“We are excited that a company which we believe is on the verge of becoming a significant driver of product and process innovation in the energy storage space is working with our technology for their game-changing solid-state battery concept.”

The batteries will be produced by Sakuu’s Kavian platform in gigafactory settings, which enables rapid, additive manufactured, high-volume, low-cost, and sustainable battery production to meet mass-market demand.

Sakuu operates two facilities in Silicon Valley, California, where it is headquartered: a solid-state battery pilot line facility and a battery printing and engineering facility.
