Hydrogen vs. Battery Electric Cars

We dont have technology to recycle li-on battery. Image all those batteries be buried in earth and corrupte and kill everything near them. More electric cars = more co2 coz 60-70% electicity come from burning coal or gas. Modern cars emit 100-150 co2 and it is low. Maybe think how to recycle tires , your brakes etc. I think people need to creat fuel with low emission
 co2. And use it in modern or new engine, use already created infrastructure.
