Sounds almost too good to be true!

"... using a chemistry of renewables to store over 220 Wh/kg. Singaporean startup Flint ...

Flint says the rechargeable batteries will have a life cycle comparable to traditional battery technologies, unlike other single-use paper battery designs. ...

The company's proprietary battery chemistry relies on cellulose, the structural plant material used to make paper, as the medium for ion transfer between the anode and cathode.
