軽量ノートパソコンから電気自動車の長距離運転まで、無数の用途においてリチウムイオン電池のエネルギー密度と性能を高めることが求められています。バッテリー電極はこれらのバッテリー機能に直接影響するため、技術を次のレベルに促進させようとしているバッテリー研究者は電極とその構成要素に特別な関心があります。バッテリー電極用スラリーの処理はまた、製造工程の重要なステップであるため、効率を向上させながらコストを削減させる重要な機会を与えます。
Over the past decade, battery research, development, and quality control have adopted in-situ and in-operando isothermal microcalorimetry (IMC) as the leading method to evaluate heat flow during lithium-ion battery cycling. While cycling a cell to failure can take many months, emerging diagnostic tests are able to predict long-term behavior in a matter of weeks.
Lithium-ion batteries represent the dominant rechargeable battery on the market today. They can be found in many applications including consumer electronics, electric vehicles and industrial equipment. Due to the tremendous adoption of lithium-ion batteries in recent years, battery technology is the focus of a diverse set of research areas aiming to improve battery lifetime, performance and safety.
Catalytic reactions are everywhere: from plastics and bread to over 90% of all chemicals worldwide, countless goods and materials are manufactured with the aid of catalysts.1 Catalysts are substances that speed up sluggish chemical reactions. Faster reactions are more technologically and economically competitive. Furthermore, optimized catalysts offer a huge potential to reduce energy and resource consumption and lower carbon dioxide emissions.
Whether you’ve used a cell phone or driven an electric vehicle (please, not at the same time), you’ve probably come to realize that lithium-ion batteries are taking over the energy world. They power our portable electronics, vital medical equipment, electric vehicles, and renewable energy storage. As the market expands, researchers are finding ways to make Li-ion batteries increasingly powerful, dependable, and safe, all while minimizing production time and cost.
In autumn of 2021, the 26th UN Climate Change Conference of the Parties (COP 26) met in Glasgow to work out agreements to curb greenhouse gas emissions and prevent additional climate change. COP 26 built upon the Paris Agreement to limit global warming below 2-degrees Celsius by achieving net zero carbon dioxide (CO2) emissions. These two agreements will shape how governments and industries work together to reduce climate change over the next decade.
Lithium-ion batteries are transforming key industries through efficient power storage. Today’s battery scientists must build upon previous discoveries while focusing on the battery elements that will drive progress in leading application areas.
