Here is some technical details for those interested in such stuff!:-

 

Nissan Leaf with a 30KwH battery pack this car has zero CO2 or any other emissions. Using much safer technology than mobile phones - the battery is an air-cooled stacked laminated lithium ion manganese oxide pack. It gets fully recycled after the cars life is at an end and doesn't get put into landfill (as some have claimed!).

The synchronous and brushless AC electric motor is about the size of a football but is rated at up to 90Kw (120 hp) - however, an electric motor has 100% of it's torque available immediately  from 0MPH meaning that with it's 280Nm of torque it can take off at traffic lights surprisingly quickly but never with any worry about it stalling - there's no engine to stall anyway!

There's all the usual safety features plus the fact that it's peacefully and relaxingly quiet and all the energy I use for it is sourced 100% from renewable power. It's classified as an automatic (so passing your test in this car means you can drive any automatic regardless of whether it's petrol / diesel / electric or hybrid) and is very, very easy to drive. What sets this car apart though and makes it a joy to drive - not just for nervous pupils or those who don't like gears or clutches - but for anyone else too is because it's still a drivers car due to the fantastic torque of the electric motor and it's great handling as the battery pack is low down on the floor of the car to give a low centre of gravity. The best reason though is it's zero emissions credentials and much smaller impact on the environment than any petrol or diesel car.

Sometimes I feel like this quote:-

 

Some info on car battery ingredients and recycling

 

Lithium - Sourced mostly from evaporation pools in desert areas. Brine water is pumped to the surface and the sun does the rest! Contrary to popular belief the lithium isn't a big part of the battery pack as Elon explains here:-

"The lithium is two percent of the cell mass. So it's like salt in the salad; it's a very small amount of the cell mass and a fairly small amount of the cost. But it sounds like it's big because it's called 'lithium ion,' but really, our battery should be called 'nickel graphite,' because it's mostly nickel and graphite." Elon Musk

Nickel - Mined in Australia, Canada, Indonesia, Russia and the Philippines. There is a CO2 implication in the production of nickel but these extra emissions associated with BEV (battery electric vehicles) manufacturing can be rapidly offset by reduced emissions from driving. See here for a 2016 study by the union of concerned scientists comparing EV's to petrol / diesel cars over their full lifetimes:- Click Here

Graphite - Most of the world’s graphite comes from China, with India and Brazil placing second and third in graphite production. However, other sources, like Berkwood’s Lac Guéret project in Quebec, are still being uncovered. Graphite is mined either through open-pit methods or underground mining and the substance is found in metamorphic rocks such as limestone. For more info:- Click Here

Cobalt - Some sources are from DRC which are in conflict zones and there are stories of forced child labour. Most EV companies are therefore trying to source from other areas. Tesla source from the Philippines Years ago when lithium ion batteries first came out (for laptops and phones etc.) they typically contained 20-30% cobalt. Today's typical EV has less than 3% cobalt in it's battery pack. In the very near future there will be none at all as the next generation of batteries wont need the stuff:- Click Here

What happens to an EV battery after it's life is over in a car? - Actually they can have a second life! Even though after around 10 -15 years or 150,000 miles (or more like 500,000 miles in a Tesla) the battery may be old for a car they can still have a useful capacity as a storage battery, some houses have these installed to store solar energy. There are already many companies doing this such as Nissan, Tesla and others like this one called Greenlight:- Click Here

Battery Recycling - After a further 10 years or so as a storage battery it's the end of the useful life of the cells. Current EU rules already require 50% of battery materials to be recycled. However, there are now many companies who take these old batteries apart and use a process that makes more than 80% of EV battery materials recyclable. In particular, it focuses on recapturing the nickel, cobalt, and other metals that are associated with environmental or humanitarian concerns:- Click Here VW and others have plans in place to better that to 97% recovery of materials within 10 years.

A Rant

Compare this for a minute to a petrol or diesel car. Oil is drilled - often getting spilt into the sea in the process. Massive amounts (225 tons a day for a typical oil tanker) of particularly dirty fuel (called bunker fuel) are then used to transport this crude oil to refineries. There are many spills of crude oil every year during tanker shipping - in just 2018 alone there was 116,000 tons spilt Click Here. The refineries use copious amounts of electricity (in the UK all 3 are powered by coal) in fact about 2 cities worth each to refine it into petrol / diesel. This then gets transported via heavily polluting diesel trucks to the forecourts of petrol stations. None of this catalogue of pollution and CO2 producing steps are ever known by members of the public - all we have are the kg of CO2 per mile driven and none of the proceeding steps I've just mentioned Click Here and then it's just burnt in our cars and gone - except it's just more fuc*king pollution and CO2 dumped into the atmosphere! The electric future will be much, much cleaner - The raw materials are not burnt and released into the air, they are recycled and used again and again! We must fight against the misinformation war against EV's led by oil interests.
