TDK Ventures invests in seed cycle for lithium-ion dry electrode manufacturing start-up, AM Batteries


[ad_1]

– AM Batteries (AMB) is a Boston-based start-up additive manufacturing company focused on the lithium-ion dry electrode market

– AMB’s core technology combines unique knowledge of multiparticulate physico-chemical modeling, surface chemistry and battery electrode process engineering to enable mass production of dry electrode technology

– TDK will support the rapid maturation and commercialization of AMB’s revolutionary dry electrode coating methodology through its manufacturing expertise, thereby improving the efficiency and manufacturing capacity of lithium-ion batteries by aligning perfectly on the current workflow.

SAN JOSE, California, September 20, 2021 / PRNewswire / – TDK Corporation (TSE: 6762) today announced that its subsidiary TDK Ventures Inc. is investing in AM Batteries (AMB) to support the commercialization of its dry electrode coating technology that improves battery manufacturing lithium-ion built on a bedrock of unrivaled expertise in advanced chemistry, surface science and precision additive manufacturing. AMB’s electrodes not only have the potential to reduce costs, but also offer a path to fast charging, higher energy density and adaptability. AMB attracted the industry early on to adopt this technology on a pilot scale to mass production.

AMB has developed a new Li-ion additive manufacturing technique whereby active materials (cathode / anode) are charged and sprayed onto metal foil current collectors, which are then processed to their final state to manufacture batteries without use toxic solvent. This dry coating method offers significant cost and energy savings over advanced “wet coating” procedures, offering a dramatic improvement in the durability of the overall cell manufacturing process. TDK Ventures’ investment in AMB marks its continued focus on core technologies that catalyze broader decarbonization efforts through sustainable and scalable battery technologies.

“Our technology is extremely innovative and off the beaten track,” said Yan Wang, co-founder and CEO of AMB. “TDK Ventures’ proprietary knowledge and unique insight into battery manufacturing has validated our own technological advancements. They have also played an important role in bringing together a large group of financial, strategic and OEM partners by sharing their core technical-economic knowledge, thus helping us to bring together a set of world-class partners for our business. “

Riding the rising tide of electric vehicles, demand for lithium-ion batteries has never been higher – with a projected need of over 2,000 GWh by 2030. With this significant demand for manufacturing capacity, the environmental and carbon footprint is increasingly monitored. Current wet electrode manufacturing techniques consume up to 50% of the total manufacturing energy of the entire battery, require a large factory footprint to dry the solvent, and increase the CAPEX required for factories. manufacturing. One of the most fundamental problems for battery manufacturers today is to refine manufacturing techniques. Refining manufacturing techniques to remove solvent is one of the most fundamental issues for all battery manufacturers today in the consumer electronics, large-scale energy storage, and electric vehicle markets. .

On Tesla’s Battery Day 2020 last year, CEO Elon musk said that the dry electrode technology is one of the most essential components for a radical change in the reduction of the costs of electric vehicle batteries; he also said there was a lot of room for maturation and improvement in technology. Tesla acquired Maxwell Technologies in early 2019 with a view to potentially commercializing its dry electrode technology.

“AMB has designed a three-stage electrospray system that aligns perfectly with the existing lithium battery manufacturing process flow, which is not the case in competing solutions, which puts them at the forefront. industry, ”said Nicolas Sauvage, Chairman of TDK Ventures. “In the future, we believe that battery manufacturers will differentiate not only on energy density, fast charge capacity or cost / kW, but also on the amount of CO.2 emitted by the amount of stored energy, which is a measure of the durability of the electrode manufacturing process. This positioning is a whole new value proposition for next-generation battery manufacturers and electric vehicle OEMs that align with consumer needs. “

Eric Rosenblum, Managing Partner of Foothill Ventures commented: “The market for electric vehicle batteries is one of the most important markets in the world, and this technology addresses two of the biggest issues: cost and durability. Dr. Yan wang has proven to be one of the most successful battery inventors and serial entrepreneurs, and we are also delighted to partner again with TDK Ventures. “

AMB has closed its tour of $ 3 million in financing September 2021 with TDK Ventures and Foothill Ventures co-leading the cycle. SAIC Capital (Tier I manufacturer), VinFast (Vietnamese electric vehicle OEM), Doral Energy-Tech Ventures (Israel Renewable Energy Company), Creative Ventures (Silicon Valley financial venture capital firm) also participated in the round. In January 2020, the founders of AMB obtained a $ 2.4 million three-year research grant by the United States Advanced Battery Consortium (USABC), based on its strong fundamental academic progress.
