Hemant Rohera — Bioelectronics, Energy Storage and Power Electronics

I have published three linked notes on the mechanism behind hybrid energy storage. Between them they answer one question — why pair a battery with a supercapacitor at all — without asking anyone to take a claim on trust. Each is on the hub in full; this is the short version of all three, with links. One: a battery and a supercapacitor are not two grades of the same thing A battery stores energy chemically. Charge is held by redox reactions in the bulk of the electrode: ions move into and out of the lattice and the material itself changes state. The whole volume participates, so the energy per kilogram is large — and because the process involves mass transport and a chemical change, it takes time and it wears the electrode out. A supercapacitor stores energy electrostatically. Ions gather against the electrode surface and disperse again. Nothing reacts, nothing changes phase. Only the surface participates, so the energy per kilogram is small — and because nothing is being worn out, i...

Everything else I publish states what the record supports. This states what it does not. Eleven questions across the three technologies are genuinely open — some because the work has not been done, some because it has been done and not published, and some because the answer may turn out to be unwelcome. Each is written as a question rather than left for a diligence team to find. Why publish this at all Two reasons, and neither is modesty. The first is that every one of these questions will be asked eventually, by a licensee’s engineers or a reviewer or a regulator, and the answer they get should be mine rather than a guess. A gap someone else finds costs more than a gap you declared. The second is that the strength of a claim is set by the weakest thing standing behind it. Publishing the open questions is what makes the closed ones worth something: if I will tell you what I cannot show, you have a reason to believe me about what I can.

Three registered Indian companies develop and commercialise the three technologies. Each has a Corporate Identity Number you can check against the public register in about a minute. None of them owns a patent , and that is deliberate — it is also the first thing a counterparty needs to understand about the structure.
