Background Information The development of advanced materials in electrochemistry may be described as an enabling technology. These novel materials will help revolutionize the performance characteristics of electrochemical applications such as lithium ion batteries, photovoltaics devices, electrochromic displays, electro-optic devices and many others. The development of these advanced materials requires a highly technical background and relevant experience, but most significantly relies on an innovative approach. Jerry Barker has a proven track record of new material innovation. Not only is he the named inventor on several high profile patents covering advanced materials, but he is also widely acknowledged as a world leader in the development of advanced electrode materials for lithium-ion applications. Let our organization assist you to create and protect your own advanced materials program. Lithium-ion battery materials may serve as an example of the impact of advanced materials. Until recently only a limited number of cathode-active materials for lithium ion batteries have been commercially available – i.e. those based on cobalt, nickel and manganese oxides. The commercial application of lithium cobalt oxide has been particularly successful. However, these oxide-based materials have some distinct and important disadvantages – for example, high cost, toxicity, safety concerns and limited specific capacity – thus creating a requirement for alternative and improved electroactive materials. Recently, polyanion-based cathode materials (e.g. phosphates, fluorophosphates, sulfates, fluorosulfates etc.) have been proposed for incorporation as electrode materials in lithium ion batteries. These new materials have some significant advantages over their oxide-based counterparts. It is expected that these polyanion compounds will be a commercial reality in the near future, enabling production of the 'next generation’ of lithium ion batteries. Dr. Barker has been actively involved at the forefront of this work for many years and is considered to be a pioneer of phosphate and polyanion-based electroactive materials for the battery industry. More specifically he is the named inventor on several high profile US and European patents (both issued and pending) describing the properties of these next generation materials. For more information on these issued patents please view our Patents and Intellectual Property page. The discovery of the polyanion type materials has clearly demonstrated the impact of novel electroactive materials. We at Jerry Barker Consultants are of little doubt that other novel electroactive materials will soon be discovered and believe strongly that these new compounds may help revolutionize current lithium ion technology. This creative process will mean the next generation of lithium ion technology is a reality, providing batteries with unrivalled cost and performance. Clearly Dr. Barker has a wealth of knowledge and expertise in this area and as an organization, we are ready and able to assist you in the search and development of these enabling materials. |
Advanced Active Materials for Battery Applications - IP The discovery of novel advanced materials is considered the key to improving the performance of electrochemical systems. For example, the discovery and development of new electrode materials will significantly enhance the energy density, power capability and safety characteristics of lithium-ion batteries. In addition problems associated with developing scalable manufacturing methods for these materials will also need to be addressed. Below is a brief summary of the different active materials in which Jerry Barker is either sole inventor or co-inventor. In each case, an example issued US patent or US patent application is included.
