Solid-State Battery

A Solid-State Battery uses the solid electrodes and solid electrolyte instead of the liquid or polymer gel electrolytes found in lithium-ion (Li-I) or lithium polymer batteries, and the solid electrolyte works as a role of a separator. The Solid-State Battery can be improved the stability with a solid structure, increased safety and energy density per unit area that is an emerging option for next-generation traction batteries promising low cost, high performance, and high safety. The Solid-State Battery cell is formed of (example): Cathode can be made with the same compounds as a lithium-ion battery (e.g., LFP, NMC, LMO, etc); Separator, generally ceramic or solid polymer, which also works as the electrolyte; Anode can be made of lithium metal (pure lithium). (Refer to the Secondary Battery (or Rechargeable Battery))

Scientists Present New Solid State Lithium Battery That Lasts 6000 Cycles (Source: Oil Price on 9 January 2024): By Brian Westenhaus - Harvard’s John A. Paulson School of Engineering and Applied Sciences researchers have developed a new lithium metal battery that can be charged and discharged at least 6,000 times. That’s more than any other pouch battery cell – and can be recharged in a matter of minutes. The cycle count equals more than 16 years of daily charge /discharge cycles. The research not only describes a new way to make solid state batteries with a lithium metal anode but also offers new understanding into the materials used for these potentially revolutionary batteries. The research report has been published in Nature Materials.  Xin Li, Associate Professor of Materials Science at SEAS and senior author of the paper said, “Lithium metal anode batteries are considered the holy grail of batteries because they have ten times the capacity of commercial graphite anodes and could drastically increase the driving distance of electric vehicles. Our research is an important step toward more practical solid state batteries for industrial and commercial applications.” ... 

NASA's Solid-State Battery Breakthrough Could Transform Air Travel (Source: Oil Price on 23 July 2023): By Haley Zaremba - NASA may have just found a way to change the future of the aeronautics industry. Researchers at NASA’s Solid-state Architecture Batteries for Enhanced Rechargeability and Safety (SABERS) have successfully created a solid-state battery technically advanced enough to efficiently power an aircraft. Finding a way to make air travel greener has been a critical point of interest for the global path to decarbonization, as well as for the economic wellbeing of the industry in a future where fuel prices will likely continue to increase while policy instruments such as carbon taxes become more commonplace. The transportation sector is one of the world’s biggest contributors to climate change, producing almost a quarter of total energy-related carbon emissions worldwide – and air travel is one of the biggest offenders. On average, airplanes emit approximately 100 times more carbon dioxide per hour than a shared bus or train ride. Altogether, aviation’s annual emissions are higher than most entire countries, at 1 billion tons of carbon dioxide per year. And the combustion of jet fuel doesn’t just emit carbon, it also produces “nitrogen oxides, soot, water vapor and sulfate aerosols, all of which interact with the atmosphere and have an effect on the climate in different ways and at different time scales.” ...
