Battery Development

A new white paper describes procedures and potential challenges in manufacturing solid-state battery cells in the laboratory. It is available as a free download.

DEKRA has begun construction of a battery test center at Lausitzring where systems for electric vehicles and other applications are to be tested from mid-2025.

South Korean company SK On has announced that it has co-developed a polymer electrolyte for lithium metal batteries that can be operated at room temperature.

German battery company “theion” has opened a technology center in the Berlin Adlershof Science and Technology Park. The facility will be used to further develop the companyʼs sulfur crystal batteries.

Applied safety science specialist UL Solutions Inc. has acquired BatterieIngenieure GmbH from Aachen, Germany, to respond to the increasing demand for battery performance and safety testing.

Capgemini Engineering and PEM of RWTH Aachen University have published an in-depth analysis on the “Acceleration of Battery Cell Development”.

Under the leadership of Varta AG, the research project ENTISE, in collaboration with a consortium of 15 companies and universities, is dedicated to developing innovative cell chemistry for sodium-ion batteries. The three-year project, which begins on June 1st, aims to transfer this cell chemistry into functional formats. ENTISE stands for “Development of Sodium Ion Technology for Industrially Scalable Energy Storage.” The German Federal Ministry of Education and Research supports the project with around 7.5 million euros in funding. A vital component of the project is the production of sufficient quantities of the necessary materials to build robust laboratory samples and prototypes in round-cell design. In the final phase, scaling up and transferring to the pre-industrial sector (piloting) will produce a small series of round cells that enable a robust assessment of properties in practical scenarios. Sodium offers advantages as a raw material regarding accessibility, cost, safety, and recyclability. The challenge lies in transferring this technology into industrially viable and scalable cells, with ENTISE addressing this challenge. “This project represents a milestone in developing sustainable sodium-ion batteries for the German battery community,” says Rainer Hald, CTO of Varta AG. It underscores the need for further innovative and efficient storage technologies alongside the established lithium-ion technology to advance the future of decentralized energy storage and utilization.” Source: https://www.varta-ag.com/de/ueber-varta/aktuelles/details/varta-initiiert-und-koordiniert-neues-projekt-fuer-die-energiespeicherung-der-naechsten-generation

CATL aims to produce solid-state batteries in small quantities by 2027. The technologyʼs and productionʼs current maturity level is at 4 on a scale of 1 to 9.

LABCO, a renowned German testing laboratory accredited to DIN EN ISO/IEC 17025 standards, specializes in assessing the performance of electric vehicle components. With a track record spanning over two decades, LABCO has built a reputation as a trusted partner for leading automotive brands worldwide, dedicated to advancing innovation, reliability, and, above all, safety in product development. Continuing this tradition, the LABCO Battery Test Centre (BTC) uses state-of-the-art testing procedures to determine whether battery technologies meet the highest safety, durability, and performance standards. Opened in 2022, the BTC facility is equipped to handle battery packs of up to 2.3 m x 2.3 m in size and weighing up to 2000 kg, allowing for the rigorous testing of even the most robust batteries. LABCO BTC sets new benchmarks in performance testing by simulating the entire lifespan of battery cells, modules, and packs. The center ensures comprehensive evaluation with test capabilities extending to 1200 V, 1200 A, and 1100 kW. Additionally, its two electrodynamic vibration test systems, boasting a maximum sine force of 300 kN and a maximum shock force of 900 kN, offer valuable insights into battery behavior under diverse thermal environmental conditions, spanning temperatures from -45 °C to 150 °C. Addressing the impact of environmental factors on battery systems, the facility provides climatic and temperature cabinets ranging from 0.35 m³ to 11.5 m³ in test space, accommodating a wide array of environmental conditions for thorough evaluation.
