In our journey through the world of battery technology, we have discovered that ultraviolet/visible (UV/Vis) spectrophotometry is a game-changer. You might be wondering, “What exactly is that?” Well, it is a technique where light is passed through clear, liquid samples, covering the ultraviolet to visible parts of the electromagnetic spectrum.
Why is this important? It is vital for monitoring the evolution of electrolyte solutions in batteries, which is key to assessing their health and efficiency. Have you ever pondered how we can tell a battery’s health just by looking at it? It all boils down to the spectral changes over time, which unveil the degradation of electrolytes, influenced by various chemical and electrochemical reactions during the battery’s lifespan.
By focusing on key attributes like absorption spectrum, colour, transparency, and chemical composition, UV/Vis spectrophotometry offers invaluable insights into electrolyte deterioration and its impact on battery performance. Many professionals, particularly those in quality control and research and development sectors, use this technique to align electrolyte samples with established industry colour scales, especially in the yellow spectrum, such as the yellowness index or APHA.
