This 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…

This 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…

This 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…

This story is contributed by Ronald Or and Taeik Kim Introduction The rise in global population and living standards has created an increasing demand for primary energy consumption from 13,323 Mtoe (million tons of oil equivalent) in 2020 to 16,278 Mtoe in 2050, a projected 22% growth worldwide, as shown in…

This story is contributed by Pranav Nagaveykar Electric vehicles are taking the world by storm and unleashing the potential of lithium ion batteries, which were previously used primarily in mobile phones and laptops. While these batteries are now available on a broader scale for various energy storage applications, conventional lithium…

This story is contributed by Dr. Patrick Agese Projections of Battery Market Growth in Africa Electricity access in Africa has improved markedly in the past 20 years, expanding from 25% to 47% of the population. The off-grid solar and mini-grid markets have played vital roles in this expansion. In recent years, sales of solar products have increased…

This article is contributed by Stan Sakai Thesis: We posit that the mere thought of Lithium-Ion battery (LiB) related automotive recalls and the potential liabilities therein lead to a “Safety First” approach by US automakers and battery-makers. This position comes after following the money trail of the Hyundai Kona and…

This article is contributed by Shayan Meysami Sodium-ion (Na-ion) batteries have attracted significant interest from a wide spectrum of commercial applications, including home storage, uninterrupted power supply, and low-speed electric vehicles (EVs) ranging from electric three-wheelers to trucks. The lower cost, improved sustainability, ability to be completely discharged to zero…
