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

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."
