Aviation

The driving force to move toward high-energy density storage capability of lithium-ion batteries in the aviation industry is evident – weight is paramount when you are in the air. But, so is safety. The Radio Technical Commission for Aeronautics (RTCA) is actively revising their recommendations to improve the safety of rechargeable lithium-ion battery systems that are permanently installed on aircraft. The RTCA standard defines three distinct venting categories pertaining to how off-gas emissions are vented within the battery system design and requires manufacturers to declare the venting category for their battery.

In the Nexceris Sensors division, Li-ion Tamer® systems can be used to provide monitoring of all venting categories outlined in the RTCA standards. Doing so can improve the situational awareness of your system, while providing valuable warning of a failing battery.

Electric Vehicles

Electric vehicle adoption worldwide is on the rise, with lithium-ion batteries being the source of energy in many different consumer vehicles. Battery off-gas detection is one of the many crucial safety measures necessary to safely implement lithium-ion technology in the automotive industry. 

After 10 years of research and development, Nexceris has developed the Li-ion Tamer® off-gas sensors, which are now commercially available through Honeywell and Xtralis’ distribution channels. Integration of the off-gas sensors in EV battery packs can help stop ongoing battery abuse and prevent catastrophic failure, protecting property and strengthening brands.

Marine

Marine battery safety requirements are developing quickly as adoption of battery systems is beginning to grow. The current regulations are a mix of prescriptive and risk-based rules and include scope concerning off-gassing of batteries. One of our sensor systems can be used to mitigate risks associated with off-gassing of cells.

In the Nexceris Sensors division, Li-ion Tamer® for lithium-ion battery systems can be used to provide monitoring of all venting categories outlined in RTCA standards.

Diesel Powered Vehicles

Strict limits are being placed on nitrogen oxide emissions as emission laws and regulations are becoming increasingly stringent. These requirements are creating a worldwide need for better NOx sensor products for both transportation and industrial markets. To meet this demand, Nexceris has developed a new NOx sensing technology that rapidly and selectively measures NOx in combustion exhaust streams. This technology enables accurate quantification of NOx emissions at low concentrations (< 10 ppm) with response time less than 200 milliseconds – a capability that is particularly enabling for improved closed-loop emissions monitoring in diesel engine exhaust systems. Additionally, our sensor technology offers the potential for dual sensing of NOx and NH3 in a single sensor device, which would be an important capability for silicon controlled rectifier (SCR) after-treatment systems.

What are the Benefits and Best Applications of Cathode Powders?  A Closer Look at LSM20-HP, LSC, and PCO

April 22, 2024

Cathode powders are materials that can be used in various electrochemical applications, such as solid oxide fuel cells (SOFCs), solid oxide electrolysis cells (SOECs), gas sensors, and more. Due to their unique properties and performance characteristics, Lanthanum Strontium Manganite (LSM20-HP), Lanthanum Strontium Cobaltite (LSC), and Praseodymium Cerium Oxide (PCO) are beneficial materials.
