ESEMA

Big News! Sorfin Yoshimura Joins ESEMA The energy storage industry is evolving fast, and we’re at the forefront. Sorfin Yoshimura is now part of the Energy Storage Equipment Manufacturers Alliance (ESEMA)—driving innovation, boosting supply chain efficiency, and setting new industry standards. Why it matters? -Stronger collaboration between manufacturers -Smarter, more efficient energy storage solutions -A more resilient and sustainable future We had a great experience sharing ESEMA’s vision at NAATBatt International. The industry is growing rapidly, making initiatives like ESEMA more important than ever. Let’s power up together—follow ESEMA’s LinkedIn for the latest updates.

As proud members of NAATBatt International, we provided our first member update today. We look forward to jumpstarting battery equipment manufacturing in the US and EU. Thank you Sebastian Montoya ! While utilizing the core competencies and strength of our 5 companies, hundreds of employees and $200M+ in sales, we realize it is only a driver. Our network of global partners in materials and equipment manufacture close the gaps to attack non value add processes or turnkey operations. We want to thank again the likes of Tal Sholklapper, Bob Galyen and Jeff Yambrick for all the support and guidance in getting our Alliance going. Disruptive innovation through collaboration. #zincbatteries #sodiumbatteries #lithiumbatteries #leadacidbatteries MAC Engineering and Equipment Co., Inc.

February 18th is National Battery Day, it is also Alessandro Volta’s birthday. On March 20th, 1800 a letter addressed from Alessandro Volta to Joseph Banks, president of the Royal Society of London, reported the first “electric pile.” The first modern form of batteries was the electric pile, or Voltaic pile which is credited to Alessandro Volta. The birth of the Voltaic pile came from a dispute between Volta and another Italian scientist, Luigi Galvani. Galvani experimented by attaching a frog to an iron rail and held the frog with a copper hook through its spine, turning the frog into a conductor for the current causing it to twitch. ?Which lead Galvani to believe he had discovered a new electricity he called “animal electricity.” He believed the frog legs were generating the current rather than being a vehicle for the current. Volta publicly disagreed with Galvani sparking controversy and a good old fashioned scientific dispute. Instead of frogs, Volta used paper soaked in salt water (or salt vinegar) placed between discs of copper and zinc. Touching a piece of wire to the top and bottom of the pile allowed the electricity to flow through the wire giving us the first battery. So, in theory, one could make their own Voltaic pile with pickle juice, pennies, and some zinc plated washers from the hardware store? It’s incredible how far we’ve come from voltaic piles to the sophisticated energy storage solutions we have today. Since today is National Battery Day, MAC would like to extend a thank you to Alessandro Volta for laying the foundation for energy storage. MAC can help streamline the battery making process, but we wouldn’t be helping anyone make the best batteries in the world without Volta. #energystorage #batteries #Volta #Voltaicpile #electricpile?#AlessandroVolta #Alessandro #engineering #automation #industrialengineering #industrialautomation #MAC #MACengineering #NationalBatteryDay #BatteryIndustry #MadeInUSA #AmericanManufacturing

Great day 2 with the ESEMA team. Very productive meeting and thanks to all for coming to St Louis or participating online. My special thanks goes to Nick Hennen for hosting us. What I really love about this alliance, likeminded people are putting heads together and being creative for the benefit of our customers. What next-gen solutions can we develop to increase productivity of our customers? Besides our skills what other service providers can we partner with and bring into the discussion in case our customer needs it. I feel the commitment from all alliance members and the absolute will to make a difference with our work. And I feel trust between longterm friends. It is great fun to work with you guys. Today we made another big step. Thanks Julie McClure, Douglas Bornas, Bjoern Stoll, Scott Fink, Jimmy Stewart, Michael Wipperfürth, Nick Hennen to make it happen.
