Lithium and Sodium Active Materials

As some of you will know, over the past few years I have been involved in the discovery and development of many new active materials for both lithium and sodium battery applications. I was asked at a meeting recently if I had compiled a list of these inventions. The short answer is "No", but there is a limited summary of some of these materials on my website (www.jerrybarker.co.uk) although this is certainly not an exhaustive list.

So below is a list of the different active materials in which I am the inventor or co-inventor. In each case, I have also included one of the associated US patents, but in most instances there will be multiple issued patents and patent applications and the one shown here may not be the earliest filing. It is simply listed as an example. Please also note that I have probably missed out a few materials, so I will no doubt need to amend this table in the near future (i.e. when my memory is fully functional!).

I have not added hyperlinks to all these patents, so if you need additional information I suggest you use:

Faradion - a new Energy Storage Company

A new UK-based energy storage company, Faradion, has been established in Sheffield, Yorkshire. The company is named after chemist and physicist Michael Faraday – who was pivotal in developing the science of electrochemistry – Faradion plans to use a number of technologies which can potentially halve the costs of storing electrical energy.

Jerry has worked in the UK, Denmark and the US and has managed materials research labs in Europe and North America. He is currently located in the UK where he has consulted for, and advised a number of battery R&D companies, varying in size from small university startup to global multinational. He has also consulted and advised on solar photovoltaics (PV) where he is widely regarded as a world expert on the electrodeposition of thin film semiconductors for PV and other applications. In his early career Jerry spent time at UCSB where he collaborated with the Nobel prize winners Alan Heeger and Hideki Shirakawa on alkali metal doped polyacetylene.

Jerry has published extensively in the energy storage area (h-index = 56, total number of citations >11,000) and is a named inventor on more than 120 issued US patents. He has appeared as a patent litigation expert witness in Europe and in North America. He has also acted as the due diligence technical expert for a number of VC-backed startup companies. Additional information on Jerry's background may be found at the website:
