In theory, China is the perfect market for the electric car to thrive. Sixteen of the 20 most polluted cities in the world are said to be in China.
This year, the air in the Chinese capital reached 40 times the safe limit. The sheer number of cars and the poor quality of fuel are significant contributors to what has become known as 'airmageddon'.
The global electric car revolution has, thus far, failed to materialise. A combination of 'range-anxiety', high prices and unappealing models has discouraged the public to buy.
Unimpressed by poor sales, governments have been reluctant to invest in infrastruture. A vicious cyclehas formed which has been hard to break. But China could hold the key.
