Singapore startup Flint says it has come up with a way to replace the lithium in a battery with paper.
The startup coats cellulose paper, anode and cathode in hydrogel before baking it in a vacuum oven.
Flint's battery only has three components: a zinc-based anode , a manganese-based cathode and the paper separator.
Flint needs to increase the volumetric density of its paper batteries to match the capacity of lithium batteries.
The startup bootstrapped $ 50,000 and the Singapore government gave it another $ 100,000 .
Flint also needs to improve the lifecycle of its batteries before they can go to market.
