Greener Batteries

Introduction

New-age lithium batteries fitted in electric vehicles are more greener than believed earlier. Life cycle study of the new battery shows it causes 15 per cent of the total pollution in the vehicles, less than previous assumptions. The cost to the environment depends more on the kind of energy used to charge the battery. If coal is used the burden increases by 13.4 per cent.
