Hello,
Rubber could revolutionize electric car batteries
"Researchers have succeeded in creating batteries for electric cars that are safer, more ecological, and with better capacity. Their secret? A rubber electrolyte.
Such batteries would be more stable and safe, better for the environment and cheaper to produce. This technology is primarily intended for electric cars and manages to achieve an energy density of more than 410 watt hours per kilogram , compared to around 260 watt hours per kilogram for the batteries of Tesla cars . Rubber-based batteries could therefore greatly increase the range of electric cars."
