A lot has been written regarding rechargeable lithium (LI) batteries and sustainability. Primary (non-rechargeable) Li batteries can also make major contributions to improving the sustainability of the systems where they are used. This FAQ reviews some of the factors related to the sustainability of primary Li batteries including key performance indicators (KPIs), downcycling versus recycling,…
Rare earths and EVs — it’s not about batteries
Rare earths play an important part in the sustainability of electric vehicles (EVs). While there are sustainability challenges related to EV batteries, rare earths are not used in lithium-ion batteries. They are necessary for the magnets that form the main propulsion motors. The batteries mostly rely on lithium and cobalt (not rare earths). At the…
What’s the difference between quick charge and extreme fast charge?
Several things. First, quick charge is used with devices like smart phones and tablet computers, while extreme fast charging (XFC) is used with electric vehicles (EVs). Quick charge (QC) is generally slower than extreme fast charge. QC has competitors like universal serial bus power delivery (USB-PD), IEC 62680-1-2:2022, and USB extended power range (EPR). Tesla…
EV basics: Comparing innovative battery chemistries
While lithium-ion battery chemistry dominates the current electric vehicle market, scientists are working to develop innovative battery chemistries that address the known challenges the existing chemistry presents. By Adam Kimmel for Mouser Electronics Sales of electric vehicles (EVs) continue to outpace the overall automotive segment, with EV market shares of 5.2% in Q1 and 5.6%…
What battery chemistries are used in grid-scale energy storage?
Expansion of grid-scale energy storage is important to enable the transition to variable renewable energy (VRE) sources such as wind and solar, and a green energy economy. The use of battery energy storage systems (BESS) is a key to enabling the growing penetration of VREs. BESS installations are classified as behind-the-meter (BTM) or front of…
Charging electric vehicles, Part 1: The numbers
It’s nice to envision that recharging an electric vehicle is as straightforward as filling up an internal combustion vehicle, but it’s not: there are multiple charging, power, and connector options as well as limitations. You’re driving your internal-combustion (IC) car, and the gauge indicates it’s time to get “gas” (of course, it’s actually gasoline). So […]
