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…

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 battery is not an ideal finite power supply. The energy stored in a fully charged battery cannot be supplied to the digital circuitry to its full extent because the amount of energy a battery can provide depends on the current drawn from the battery itself. In other words, the higher the discharge current, the…

There are many alternatives to Li-ion batteries, including fuel cells, various types of supercapacitors, redox flow batteries, novel Li-based chemistries such as lithium-sulfur (LiS), and more. This FAQ focuses on alternative non-lithium rechargeable battery chemistries, including calcium-ion (Ca-ion), magnesium-ion (Mg-ion), sodium-ion (Na-ion), zinc-ion (Zn-ion), iron-air (Fe-air), and sodium-sulfur (NaS) that can be more readily integrated…

Littelfuse, Inc. announced the new ITV4030, a series of 22 amp, three-terminal, surface-mountable Li-ion battery protectors. These 4.0 x 3.0 mm devices protect battery packs against overcurrent and overcharging (overvoltage) conditions. The innovative design uses embedded fuse and heater elements that provide fast response and reliable performance to interrupt the charging or discharging circuit before the […]

The electrolyte is often an underappreciated component in Lithium-ion (Li-ion) batteries. They simply provide an electrical path between the anode and cathode that supports current (actually, ion) flow. But electrolytes are a key to battery performance, and advances in electrolyte chemistries are expected to be an important development leading to high-performance, safe, and low-cost Li-ions…

Separators in Lithium-ion (Li-ion) batteries literally separate the anode and cathode to prevent a short circuit. Modern separator technology also contributes to a cell’s thermal stability and safety. Separators impact several battery performance parameters, including cycle life, energy and power density, and safety. The separator increases internal cell resistance, and the separator takes up valuable…

There are numerous cathode materials used in Lithium-ion (Li-ion) batteries optimized for various aspects of performance, but the majority of all Li-ions still use graphite anodes. That may be set to change. The use of graphite with a theoretical gravimetric capacity of about 370mAh/g is being challenged by new materials under development that offer gravimetric…
