Summary on Grant Application Form
The project aims to develop a graphene enable sodium ion battery. There are several markets for rechargeable batteries

and these can the segmented into 1. The 3C or consumer electronic Market, 2. Power tools and applicances 3.

Automotives, 4. Industrial including stationary energy stroage. SHARP sell products in all of these markets excepting the

automotive market. The sodium ion battery (NIB) is being developed as a low cost alternative rechargeable battery

technology. It is expected that NIB could directly replace lithium ion batteries (LIB) in all of the established and emerging

markets and lead acid batteries (PbA) in the low cost applications. The direct substitution of a highly developed and

optimised LIB technology for established applications will be time consuming and difficult to displace. SHARP are

interested in the emerging markets, such as stationary energy storage, where there is no currently established energy

storage technology and the development of new technologies will involve demonstrators and hence new technologies can

also be established. This project will focus on developing electrodes for a new NIB technology for longer life and higher

volumetric densities specifically for residential and community energy storage systems. In particular for coupling PV local

renewable energy generation sources with local energy storage systems. The advantages of this system are to provide a

greater self sufficiency to consumers, and to buffer an intermittent energy generation thus providing a greater stablity

between the grid and the property.

Current alternative technologies for stationary energy storage include lead acid batteries (PbA) and lithium ion (LIB). Whilst

lead acid batteries are significantly lower cost than lithium ion their life-time is significantly lower, therefore the life time

costs of these technologies are similar. Sodium ion batteries (NIB)offer a lower cost alternative to LIB however NIB

batteries have not yet been commercialised as further development is required to optimise cycle life and performance

properties, specifically for the stationary energy storage markets. The addition of graphene into the electrodes is expected

to improve the electronic transport properties of the electrodes improving the current distribution, the packing density, and

hence the volumetric energy and performance properties of the cell.
