Toyota's Battery 'Breakthrough' Can Lead To More Range, Longer Life

Toyota thinks it's found a way to create more efficient EV batteries. The car company is calling its method, which allows a free flow of lithium ions from the cathode to the anode, the "world's first behavior observation method for lithium ions in electrolyte." CNET adds:Charging and discharging batteries can create lithium ion deviation. Some of these ions can get bunched up, which can affect a battery's performance over time. In order to help reduce that bunching, scientists need to see what's happening as the ions flow through the battery's electrolyte. That observation wasn't possible until now. Toyota made has replaced the phosphorous in a traditional lithium-ion battery electrolyte with heavier elements. These heavier elements, which ferry the ions through the electrolyte, are then bombarded with powerful x-rays, which allows researchers to observe how the ions flow through. So what does this all mean? By observing the lithium ions in the electrolyte, research and development dollars can be spent on preventing the bunching that degrades battery performance. Toyota believes its breakthrough can improve electric vehicle range by up to 15 percent and improve the battery's life simultaneously.
