Dendrites are projections of metal that can build up on the surface of lithium anodes and penetrate into the battery electrolyte, eventually crossing from one electrode to the other and shorting out the battery cell. What gives rise to these metal filaments has been somewhat of a mystery, and there has been little progress on…

6K announced that its 6K Energy division has signed a joint development agreement with Our Next Energy (ONE) to develop and produce the critical battery material that ONE will use in their Gemini and Aries battery platforms. The agreement strengthens the procurement of domestically produced electric vehicle batteries for automotive OEMs manufactured by ONE made with…

By Sol Jacobs, Tadiran Batteries At the heart of the IIoT are lithium battery-operated remote wireless devices that bring digital connectivity to emerging and evolving technologies such as SCADA, process control, industrial robotics, asset tracking, safety systems, environmental monitoring, M2M, AI, and wireless mesh networks, to name a few. Battery-powered remote wireless devices serve to…

Solid-state battery materials maker Natrion released performance metrics for its patented solid-electrolyte separator in state-of-the-art Li-ion battery cells using graphite anode. The new material, LISIC278, is a version of Natrion’s patented Lithium Solid Ionic Composite (LISIC) electrolyte made to mimic the exact specifications of a standard polyolefin separator while utilizing significantly less liquid electrolyte. LISIC…

A research team comprised of Princeton, Vanderbilt, and Argonne and Oak Ridge National Labs researchers claims to have uncovered a hidden flaw behind failures in solid-state batteries. In a solid-state battery, ions move through the battery within a solid material, in contrast to traditional lithium-ion batteries, in which ions move in a liquid. Solid-state cells…

Thermal runaway happens when a lithium-ion cell, or a small region within a cell, reaches a critical temperature where the materials start to undergo decomposition reactions. These reactions then generate significant additional heat. The decomposition reactions are temperature dependent, increasing exponentially as the temperature increases. Once decomposition starts, a chain reaction causes the battery to…

A new approach to extracting residual energy from waste batteries could serve as a starting point for waste reduction research   Batteries find use everywhere. But once discharged, they are discarded. For many years, discarded batteries have been salvaged for valuable metals. However, the residual energy in them have seldom been recovered. In a new…

By JD DiGiacomandrea, Green Cubes Technology As the number of cell sites increase and their sizes decrease, engineers have options to consider for battery backup. Differing battery chemistries offer more choices and different performance levels. Selecting the right battery chemistry for each application is critical to ensure reliable, long lasting, and cost-effective power delivery. The…

Halo Microelectronics announced the release of its HL7090, a fully automatic and highly integrated lithium battery charging management IC with one switching charger, two linear chargers, and full-range programmable charge parameters through an I2C compatible interface. The HL7090 is a compact, flexible, and high-efficiency switching-mode charge management IC for single-cell Li-ion and Li-polymer batteries used…

Leland Teschler • Executive Editor If you wandered around the Society of Automotive Engineers’ annual trade show earlier this year, you would have seen a number of ideas aimed at cutting power consumption in electric vehicles. One development in that category was from a company called BetterFrost. It devised a more energy efficient windshield defroster.…
