The Current State of Batteries Today, state-of-the-art primary battery technology is based on lithium metal, thionyl chloride (Li-SOCl2), and manganese oxide (Li-MnO2). They are suitable for long-term applications of five to twenty years, including metering, electronic toll collection, tracking, and the Internet of Things (IoT).
As the world decarbonizes, researchers and industry are applying an all-hands-on-deck approach to batteries. Sodium-ion replacements for the more popular lithium equivalent is one alternative as extracting lithium becomes more expensive and comes with geopolitical challenges. Solid-state batteries (SSBs), where all components including traditional liquid electrolytes are solids, constitute a ...
One of lithium-ion battery technology’s biggest challenges is metal electrode degradation, which researchers are looking to solve with an unlikely material: tin foam.
According to IDTechEx’s “ Solid-State and Polymer Batteries 2021-2031: Technology, Forecasts, Players ” report, research and development for next-generation solid-state batteries is on the upswing, fueled by high expectations for the electric vehicle (EV) market, especially pledges of billions of dollars of support in President Joe Biden’s proposed infrastructure bill. When eventually ...
Content A Safe, Cold-Sintered, Solid-State Battery A Safe, Cold-Sintered, Solid-State Battery Imagine a battery that charges faster, lasts longer, and can’t catch fire. That’s the promise of solid-state technology, and researchers have been racing to make it practical. Energy storage is the key to our increasingly portable and electric world.
On Oct. 29, Argonne National Laboratory announced a breakthrough of its own, in the form of a “dual-gradient” design for a lithium-ion battery’s cathode, which increases a battery’s energy storage capacity, stability, and lifetime, and cuts costs, which could greatly accelerate EV and grid battery adoption.

This is especially important for longer-range applications such as package delivery or monitoring and surveillance. Factors that impact flight time include drone weight, battery fail-safe settings, and payload power draw. Lithium-polymer batteries are often sold as flight packs that provide longer flight times.
Fast-charging lithium-ion batteries power the vast majority of the devices we use every day, including cellphones, computers, and electric vehicles. Unfortunately, a major limitation is that they are susceptible to overheating and catching fire. As important as fast charging is for making electric vehicles (EV) more competitive and convenient, the underlying electrochemical phenomena that ...
