Samsung recently announced the development of a groundbreaking solid-state electric vehicle (EV) battery (Figure 1), promising a 600-mile range, 9-minute rapid charging, and a 20-year lifespan. In contrast, EVs with conventional lithium-ion (Li-ion) batteries typically offer a 250 to 350-mile range, 25 to 30-minute rapid charging, and an 8 to 15-year lifespan. Although many major…

First-generation solid-state batteries are poised to boost the driving range of electric vehicles (EVs) by 50% to 80%. Solid-state batteries could extend this range even further, with some automotive manufacturers ambitiously targeting 900 to 1,000 miles per charge. This article reviews how solid-state technology increases EV battery capacity and range, discussing lighter and more energy-dense…

Lithium-ion (Li-ion) battery traction packs power most electric vehicles (EVs) on the road today. These batteries enable electric motors to efficiently generate the high torque required for rapid acceleration and consistent speeds. Although Li-ion batteries offer high energy density and a relatively long lifespan, many automotive companies are actively researching and developing solid-state battery technology.…

The flawless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries because it uses non-flammable electrolytes. However, it suffers from self-discharge due to the crossover of active materials, generated at the positive graphite felt (GF) electrode, to the negative electrode, significantly affecting performance. Now, researchers have developed a novel nitrogen-doped mesoporous carbon-coated GF…

Littelfuse, Inc. announced the extension of its ITV2718 surface-mountable Li-ion battery protector series. These fuses safeguard Li-ion battery packs against overcurrent and overcharging (overvoltage) conditions—even when fast charging. The latest addition, the ITV2718, provides a five-amp, three-terminal fuse in a 2.7 x 1.8 mm footprint. The innovative design utilizes an embedded fuse and heater element combination…

Battery technology is the foundational element of electric vehicles (EVs), influencing their efficiency, range, charging speed, lifespan, cost, and overall performance. Engineering firm Bosch Rexroth is well aware of how battery manufacturing affects every one of these factors. It believes innovations in battery technology and advanced manufacturing processes are essential for the widespread adoption and…

The electric vehicle (EV) battery supply chain is vast and complex, spanning mining and processing to assembly and end-of-life management. This article reviews the supply chain’s four primary stages: upstream, midstream, downstream, and recycling or repurposing. It also highlights major supply chain challenges and explores potential solutions to improve resiliency, efficiency, and sustainability. Defining the…

Eko Health has learned a bit about batteries and Bluetooth while developing AI-powered medical devices to help physicians detect cardiovascular disease. Eko Health’s devices include hardware — in the form of its Duo and Core digital stethoscopes — and algorithms that analyze the acoustic and electrocardiogram (ECG) signals collected by those handheld devices. Together, their…

by Luca Vezzadini, ZIVAN The urgency of mitigating climate change and reducing greenhouse gas emissions has prompted businesses to adopt more sustainable transportation solutions, particularly electric vehicles (EVs). Lithium-ion batteries (LIBs) are at the forefront of electrification. McKinsey predicted that the entire LIB chain, from mining through recycling, could grow by over 30% annually from 2022…

In the near term, quantum sensors are being developed that can more accurately measure EV battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could dramatically improve the speed and efficiency of battery charging. The energy remaining in an EV battery has been estimated using…
