We demonstrate a shear thickening electrolyte that stiffens into a solid-like barrier during a high energy event, like a car crash. This barrier prevents the electrodes from shorting during an impact, reducing the risk of fire or catastrophic safety events. In addition, we have demonstrated the ability to cycle NMC/graphite lithium ion cells over 200 cycles with no loss of capacity after formation. This chemistry introduces multifunctionality to a material previously feared due to its flammability.

高抗冲电池的剪切增稠电解质

我们演示了一种剪切增稠电解质,该电解质在高能事件(例如车祸)中会变硬成固体状的屏障。该屏障可防止电极在撞击过程中短路,从而降低发生火灾或灾难性安全事件的风险。另外,我们已经证明了NMC /石墨锂离子电池能够循环200次以上的循环能力,并且在形成后不会损失任何容量。这种化学作用将多种功能引入了以前由于其易燃性而令人担忧的材料。
