The Next Frontier in Battery Technology
The rapid transition toward renewable energy and electric transportation hinges fundamentally on breakthroughs in battery chemistry. While conventional lithium-ion batteries have powered consumer electronics and the initial wave of electric vehicles with remarkable success, they face inherent limitations in energy density, charging speed, and thermal stability. The flammable liquid electrolytes used in traditional cells pose persistent fire risks under mechanical impact or overcharging. To address these vulnerabilities, researchers are pioneering solid-state batteries, which replace volatile liquid solutions with solid ceramic or polymer electrolytes. This architectural shift not only virtually eliminates catastrophic combustion hazards but also accommodates pure lithium-metal anodes, substantially boosting energy density. Consequently, future electric vehicles equipped with solid-state cells could achieve driving ranges exceeding eight hundred kilometers on a single fifteen-minute charge.
The word "volatile" in the passage is closest in meaning to ----.
  1. A)frozen solid and unmoving
  2. B)completely fireproof and safe
  3. C)readily evaporable and easily ignited / unstable
  4. D)extremely durable and permanent
  5. E)harmless to biological tissues
Cevabı ve çözümü göster
Doğru cevap: C) readily evaporable and easily ignited / unstable
Çözüm: "Volatile" uçucu, kararsız ve kolayca alev alabilen ("readily evaporable and easily ignited") anlamına gelir. Doğru cevap C'dir.
