The project aims to develop a graphene enable sodium ion battery. There are several markets for rechargeable batteriesand 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 theautomotive market. The sodium ion battery (NIB) is being developed as a low cost alternative rechargeable batterytechnology. It is expected that NIB could directly replace lithium ion batteries (LIB) in all of the established and emergingmarkets and lead acid batteries (PbA) in the low cost applications. The direct substitution of a highly developed andoptimised LIB technology for established applications will be time consuming and difficult to displace. SHARP areinterested in the emerging markets, such as stationary energy storage, where there is no currently established energystorage technology and the development of new technologies will involve demonstrators and hence new technologies canalso be established. This project will focus on developing electrodes for a new NIB technology for longer life and highervolumetric densities specifically for residential and community energy storage systems. In particular for coupling PV localrenewable energy generation sources with local energy storage systems. The advantages of this system are to provide agreater self sufficiency to consumers, and to buffer an intermittent energy generation thus providing a greater stablitybetween the grid and the property.Current alternative technologies for stationary energy storage include lead acid batteries (PbA) and lithium ion (LIB). Whilstlead acid batteries are significantly lower cost than lithium ion their life-time is significantly lower, therefore the life timecosts of these technologies are similar. Sodium ion batteries (NIB)offer a lower cost alternative to LIB however NIBbatteries have not yet been commercialised as further development is required to optimise cycle life and performanceproperties, specifically for the stationary energy storage markets. The addition of graphene into the electrodes is expectedto improve the electronic transport properties of the electrodes improving the current distribution, the packing density, andhence the volumetric energy and performance properties of the cell.

该项目旨在开发一种石墨烯钠离子电池。有几个市场的可充电电池和这些可以分为1. 3C或消费电子市场，2。电动工具和电器3.汽车，4.包括固定能源储存的工业。夏普在所有这些市场销售产品，汽车市场除外。钠离子电池（NIB）是一种低成本的可替代充电电池技术。预计NIB可以直接取代所有成熟和新兴市场的锂离子电池（LIB）和低成本应用中的铅酸电池（PbA）。用高度发展和优化的锂离子电池技术直接替代现有的应用将是耗时且难以替代的。SHARP对新兴市场感兴趣，例如固定储能，目前还没有建立储能技术，新技术的开发将涉及示范，因此也可以建立新技术。该项目将专注于为新的NIB技术开发电极，以实现更长的寿命和更高的体积密度，特别适用于住宅和社区储能系统。特别是用于将光伏本地可再生能源发电源与本地储能系统耦合。该系统的优点是为消费者提供更大的自给自足能力，并缓冲间歇性发电，从而在电网和物业之间提供更大的稳定性。目前固定储能的替代技术包括铅酸电池（PbA）和锂离子电池（LIB）。虽然铅酸电池的成本比锂离子电池低得多，但它们的寿命也短得多，因此这些技术的寿命成本是相似的。钠离子电池（NIB）提供了LIB的低成本替代品，但NIB电池尚未商业化，因为需要进一步开发以优化循环寿命和性能特性，特别是对于固定储能市场。将石墨烯添加到电极中有望改善电极的电子传输特性，从而改善电流分布、堆积密度，并因此改善电池的体积能量和性能特性。
