New Products * Manufacturing High Temperature Coin Cell Module Netzsch Instrument North America, LLC has announced a high temperature coin cell module on MMC 274 Nexus. Coin cells are directly used in many consumer products and they are also a stepping stone in large battery development. Many parameters will influence the performance of rechargeable coin cell including temperature and cycling conditions. "It is important for the battery community to know the heat generation during charging/discharging cycles in order to understand the cell energy efficiency and improve cell performance, lifetime and safety." said Peter Ralbovsky, calorimetry expert at Netzsch. The new differential scanning calorimeter (DSC) is specially dedicated to coin cell battery studies and can easily be coupled with a fully featured battery analyzer. The user can perform in-situ charge/discharge tests in isothermal mode to measure battery performance and efficiency. In temperature scanning mode, the user can study cell safety and decomposition thermodynamics and kinetics up to 300°C. This information will help battery researchers understand battery behavior for R&D and QA/QC. "Our unique heat flux sensor is designed based on differential measuring principal. It results in improved stability and sensitivity to capture even weak heat signal from coin cell. A whole coin cell can be easily mounted onto the sensor." said Jean-Francois Mauger, R&D director. "The sensor is also robust enough for even destructive test of coin cell battery, which was not possible on DSC before." Applied Energy Solutions and AllCell Launch LithiumIon Material Handling Battery System Applied Energy Solutions and AllCell Technologies have launched the Superion, a lithium-ion battery system for pallet jack applications. The Superion system developed by Applied Energy Solutions offers improvements over the lead acid batteries prevalent in the industry today, including faster charging times, smaller size, lower weight and improved efficiency. More and more material handling equipment manufacturers are finding that lithium-ion battery systems offer important benefits compared to lead acid systems. Faster and more efficient charging allows operators to do away with extra batteries and battery swapping equipment while simultaneously saving money on electrical bills. Lithium-ion batteries are also virtually maintenance free because the electrolyte level does not need to be monitored, leading to further operational savings. The modular Superion system allows further flexibility, with options ranging from 5.4 kWh to 10.8 kWh. The modules inside the Superion are produced by AllCell Technologies, and integrate the company's proprietary thermal management technology to improve battery cycle life and safety. AllCell's technology employs a composite material manufactured from phase change materials (PCM) and graphite that effectively absorbs and distributes heat through the battery pack to avoid hotspots and limit maximum temperature. AllCell's PCM is particularly valuable in hot operating environments where the battery has to be protected from both internal heat (generated 24 Battery Power * November/December 2013 while charging and discharging) and external heat. According to AllCell CEO Said Al-Hallaj, "We are very pleased to be working with an innovative and forward-looking partner like Applied Energy Solutions to bring next-generation battery technology to the material handling industry. The combination of our proprietary technology with their deep industry knowledge and integration experience has produced an initial product with a very exciting value proposition." President and CEO of Applied Energy Solutions, Vern Fleming said "We are very excited to announce this partnership with AllCell because with their proprietary technology and our vast knowledge, focus on industrial applications and proprietary algorithms refined to detail state of charge information, we create a great team that can create and develop a highly refined and specialized product that will increase efficiency and the longevity of batteries in pallet jacks." NEI Introduces A Solid State Electrolyte Powder For Lithium NEI Corp. is making Li10SnP2S12, Lithium Tin-Phosphorous-Sulfide (LSPS), available for sale in powder form. LSPS belongs to a family of superionic solids that conduct lithiumions at room temperature. Commercial Lithium-ion batteries usually contain anelectrolyte that is dissolved in flammable solvents. The use of a solid state electrolyte, such as LSPS, will eliminate the flammability issue associated with currently used liquid electrolytes. Sulfide compounds with high Li-ion conductivity are not commonly available, and as such, the development of solid state electrolyte-based Li-ion batteries has been plagued by the lack of widespread availability of these difficult-to-produce materials. NEI has utilized its background in the synthesis of advanced materials to develop a process for producing sulfide materials in a form that allows them to be used in Li-ion cells. "By making solid state electrolyte powders readily available in test quantities, our intent is to make it easy for Li-ion battery researchers to develop the next generation of all-solid-state Li-ion batteries," said Dr. Ganesh Skandan, CEO of NEI Corp. "The NEI process is amenable to synthesizing variants of LSPS, such as compositional changes." Follow Battery Power @BatteryPowerMag
