Lithium-ion Batteries Key to Powering UAVs

Unmanned aerial vehicles (UAVs) are gaining more popularity in both the defense and civilian sectors thanks to their effectiveness and ease of operation when compared to manned aircraft. Battery-powered aerial vehicles are already in use for various functions of military intelligence, as well as for commercial, recreational, scientific, surveillance and agricultural applications. The large potential…

“SafeDrone by Lufthansa Technik” launches new service: Health Condition Monitoring

“SafeDrone by Lufthansa Technik” is on the verge of launching a new online service, Health Condition Monitoring (HCM), allowing manufacturers and users to monitor the technical condition of their drones after a mission is completed. This proven procedure from manned flight is now also available for unmanned aircraft. Initially, data-driven post-flight analysis is available for…

Tesla Battery

The 85 kWh battery pack weighs 1,200 lb (540 kg) and contains 7,104 lithium-ion battery cells in 16 modules wired in series (14 in the flat section and two stacked on the front). Each module contains 6 groups of 74 cells wired in parallel; the 6 groups are then wired in series within the module. As of June 2012, the battery pack used modified Panasonic cells with nickel-cobalt-aluminum cathodes. Each…

Battery cell holder, molded with 20% carbon fiber

Process of Developing Because my goal it’s about continuous development and improvement, in 2018 I will start assembling the battery packs in a special cell holder, molded with 20% carbon fiber.   Some features: Increased impact resistance. Thermal conductivity enhancement. More robust. Embedded power/balance connector.    This work by CMEC (CMIUTA Electric Company) falls under…

Cathodes: the key to the advancement of lithium-ion technology

Cathode choice is a major factor for determining battery energy density, and cathodes also typically account for 25% of lithium-ion battery costs. That means the cathode can impact both the performance and cost pieces of the $/kWh equation – and building a better cathode will likely be a key driver for the success of the…
