BYD has produced its first solid-state battery cells on a pilot line in 2024, with mass demonstration expected around 2027 and large-scale production after 2030. The company is focusing on sulphide electrolytes for solid-state cells, aiming to achieve cost parity with current NCM cells at scale. BYD plans to use these batteries primarily in high-end models while maintaining LFP cells for other vehicle segments.
A comprehensive analysis reveals that EVs offer significant long-term savings despite higher upfront costs, with break-even points around 140,000-200,000 kilometers and 30% lower maintenance costs. Financial benefits depend heavily on individual driving patterns and charging habits, with home charging providing the most cost-effective solution.
New research reveals brake dust from car brake pads may be more harmful to human lung cells than diesel exhaust, with newer copper-containing pads being particularly dangerous. While some states limit copper in brake pads, this pollutant remains largely unregulated, though electric vehicles' regenerative braking could help reduce this type of pollution.
