The most difficult part of the lithium-sulfur battery technology was the shuttle effect.
The shuttle effect occurred during the battery charging and discharging process, where the polysulfide (Li2Sx) intermediate produced by the positive electrode dissolved into the electrolyte before diffusing through the separator to the negative electrode, and finally contacting the metal lithium.
Lu Zhou was able to achieve lithium-sulfur battery technology, inventing the technology, and registering the patents before ExxonMobil could. He had a huge disagreement with Professor Stanley over lithium-sulfur battery technology.
Professor Stanley, who was backed by ExxonMobil, used subterfuge to poach an assistant from the Sarrot Institute, stealing Professor Sarrot's caged carbon molecules model.
But there was an up-side to all this.
