LUM GmbH was founded in 1994 by the Managing Director Prof. Dr. Dietmar Lerche as innovative development, production and service corporation. The headquarters are located in Berlin, Germany. The company has an office and application laboratory in France and three subsidiaries: LUM Corporation, USA, LUM (Changzhou) Instruments Co. Ltd, China, and LUM Japan Co., Ltd. LUM GmbH consists of a highly qualified, multidisciplinary team of scientists, technicians and engineers. Scientific and measurement-technology expertise has been obtained for decades in: •Particle characterization •Analysis of suspensions and emulsions, including stability evaluation •Determination of adhesive and bonding and strengths •Quality assurance and process optimization. This knowledge and its continuous extension form the basis for customer-oriented problem solving, product developments and services for our national and international customers, working in larger industrial, food, cosmetics, pharmaceutical enterprises and increasingly in the academic sector. The innovative analytical instruments “made by LUM“ are part of standard laboratory equipment in many R&D and QA/QC departments. LUM instruments enable our customers successfully to develop and formulate new and improved products and introduce them onto the market, following our slogan “The Next STEP in Dispersion Analysis and Materials Testing“.

Application of the LUMiFrac® for testing the adhesive strength of cathode & anode coatings in lithium-ion batteries In a lithium-ion battery, the smallest unit of each cell consists of two electrodes (anode and cathode), and the separator. The ion-conducting electrolyte is located in between. Typically, the main component of the anode is graphite, which is excellent for storing lithium ions during charging. However, graphite’s limited electrical conductivity can cause inefficiencies in charge and discharge cycles. To boost the anode’s performance, the coating system is applied to a thin copper foil. The copper foil enhances electrical conductivity which facilitates the electron flow between the anode and the rest of the battery, including the cathode. As a result, the battery’s internal resistance decreases, leading to more efficient charging and discharging processes. This translates to higher power output and better overall performance. The coating system prevents corrosion of the copper foil, ensures stability, and maintains electrolyte compatibility. The active material…
