Poorly made batteries of electric vehicle are putting people’s lives at risk. This is a result of carmakers’ impatience, inability to properly assess risks in emerging technologies.
Venkat Viswanathan says regional aircraft can be fully electrified with known battery tech, while narrowbody requires work. Batteries may not work for widebody aircraft, he adds.
Lithium is the key metal in EV batteries. An aluminum-air battery could do better than lithium-ion ones as it's 'potentially cheaper, safer & EVs using it will have a longer range'.
The technical challenges of making better batteries, and therefore, electric vehicles, are enormous and the fantasy of better battery science doesn’t match reality.
Japan's Hideaki Horie, who helped commercialize the batteries, has developed an approach he says can speed up manufacturing, making it as easy as 'buttering toast.'
From Silicon Valley labs to Chinese manufacturers, optimism over the lithium-ion battery’s longer-term outlook is undimmed as companies say the battery will become more powerful, cheaper and ubiquitous.
The switch from an electricity system supplied by large fossil fuel plants that run virtually uninterrupted to a more haphazard mix of smaller, intermittent renewable sources will need batteries to store energy.
