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.
Nirmala Sitharaman laid the foundation of a new site museum in 2021. It felt like a departure from the government's Harappan-centric focus. But no progress has been made since.
In Episode 1544 of CutTheClutter, Editor-in-Chief Shekhar Gupta looks at some top economists pointing to the pitfalls of ‘currency nationalism’ with data from 1991 to 2004.
Among 19 Indian firms sanctioned by US Treasury Dept was Lokesh Machines Ltd accused of coordinating with 'Russian defence procurement agent to import Italy-origin CNC machines'.
While we talk much about our military, we don’t put our national wallet where our mouth is. Nobody is saying we should double our defence spending, but current declining trend must be reversed.
