Siddhartha Banerjee, PhD·Jan 28Long-Duration Energy StorageBecause of the intermittent nature of renewable generation, long-duration storage at low costs is needed to decarbonize the electrical grid. Due to the fact that renewables have a near zero marginal cost of energy production, there is enormous opportunity for energy storage systems, which can offer load shifting, peak shaving…Battery7 min readBattery7 min read
BatteryBitsEditors·Dec 3, 2022The Evolution of Silicon in Li-ion BatteriesThis article is contributed by Singyuk Hou While a graphite anode works by intercalating lithium into the interstices between the layer structure, a silicon anode reacts with lithium via intermetallic alloying, which gives silicon the potential to store ten times more lithium than graphite for a 30% increase in the…Electric Vehicles10 min readElectric Vehicles10 min read
BatteryBitsEditors·Oct 22, 2022An Introduction to Fast Charging and Pulse ChargingThis story is contributed by Dhevathi Rajan Rajagopalan Kannan Fast charging is critical for the adoption of electric vehicles (EV’s), but higher current charging typically comes at the expense of battery life. Multistage constant current (MCC), pulse charging, boost charging, and variable current profiles (VCP) are among the fast charging…Electric Vehicles9 min readElectric Vehicles9 min read
BatteryBitsEditors·Oct 8, 2022Corrosion: The Primary Threat to Battery Pack LongevityThis article is contributed by Luke Workman and Electric Goddess Corrosion is the primary cause of failure in vehicle battery packs during their long service periods. If batteries are not adequately protected from corrosion, they will be vulnerable to failure, including catastrophic thermal events. Corrosion risk can be greatly reduced…Electric Vehicles12 min readElectric Vehicles12 min read
