Unfortunately, i'm not aware of any company that recycles batteries. some communities have battery recycling centers, please contact your local government about these centers. you might want to try buying less electronics or keep old electronics you don't use anymore so you can sell the parts which are often very valuable.
if you have to dispose of lithium ion car battery it's important not to burn them as this creates highly toxic, irritating fumes including dioxins and acid rain-inducing sulfur dioxide. please do not put into landfill because they may explode spontaneously.
this is a dangerous process that should never be undertaken by non-specialists unless you're soaking the battery in water for 24 hours first – this prevents exothermic reactions along
