Squishy batteries

'Squishy' batteries can be made from trees – this may be the future. Zero pollution.

A new type of squishy battery has been designed.
It’s made from tree pulp and is 'squishy' to touch, but is stress and shock resistant. Also, it is ideally wearable, embedded in our clothes to power own 'wearable' devices.
Importantly, it is not harmful to the environment when disposed.
The description gets a bit more technical so I’ll leave you to read the link below.
It’s amazing how our (technology) environment is transforming as a result of technology research.
