Advanced Electroactive Materials 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. This approach is often based on lateral thinking - the ability to combine concepts over a range of different disciplines. Dr. Barker, our Principal Consultant, has a proven track record of innovation. Not only is he the named inventor on several high profile patents covering advanced materials, but he is also acknowledged as a world leader in the development of advanced electrode materials for lithium ion applications. Let Jerry Barker Consultants assist your organization to create and protect its 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 LiCoO2, LiNiO2 and LiMn2O4. The commercial application of lithium cobalt oxide has been particularly successful. However, these oxide-based materials have some distinct and important disadvantages – for example, cost, toxicity, safety and specific capacity – thus creating a requirement for alternative and improved electroactive materials. Recently, polyanion based cathode materials (e.g. phosphate, sulfate 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.

Development of novel advanced materials is often 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 and specific energy characteristics of lithium ion batteries. In addition problems associated with developing scalable manufacturing methods for these materials need also be addressed.
