    It is not trivial to combined inorganic battery chemistry with organic materials other than carbon. There is a lot of 'rah rah' enthusiasm in this paper but it still merits careful study.

    Redox-active organic materials, . . .

    Here, we demonstrate that bis-tetraaminobenzoquinone (TAQ), a fused conjugated molecule with a layered solid-state structure, functions as a fast-charging, high-energy, and long-lasting OEM for LIB cathodes. As reported recently, Figure 1A). The two-dimensional (2D) layered arrangement of TAQ molecules enables facile insertion/extraction of Li+between the layers and delivers excellent rate capabilities even at full charging in as little as 3 min. Optimized electrodes deliver excellent performance even at high areal mass loadings up to 16 mg cm–2 with an areal capacity up to 3.52 mAh cm–2, which is on par with commercial lithium-ion batteries, (27)comprehensively demonstrating the viability of TAQ in practical LIBs.

    One should always read any paper, informal or otherwise, with a skeptical eye. The 'gold standard' is when an independent group publishes a paper showing a different approach achieving similar results.

    There's always confusion around organic vs. inorganic when we aren't talking about how much pesticide they sprayed on your food: Difference Between Organic and Inorganic

    But for 3.7 billion years this planet has been thriving with bacteria and to this day humans are only capable of growing about 1% of all known bacteria. As in we have very little understanding of this basic foundation of life that made the past less than a billion years bloom so plentifully with so many different lifeforms.

    But there's no doubt that bacteria has been working with electrical fields since the earliest stages of life on earth and long into the future we'll know alot more about how it can help us with electricity.

    A Sci-fi version of their use was in Star Trek Voyager, their ship had ultra fast circuitry using "gel packs" which was a type of intelligent primordial soup that managed electrons faster and more efficiently than more solid materials that aren't alive.
