A 100mL Inkwell, 1.04v-1.2v iron-based battery chemistry

2023 has been a big year for the inkwell battery. Book writing continues, and I’ve been steadily improving my construction techniques to increase total battery output. I believe I should be able to improve output enough in the next few months to reliably power a solar light in place of a lithium cell. Please consider joining my mailing list for more news and information.
