Pike research has predicted a 20-fold increase in 10 years of the energy storage market. After Fukushima nuclear disaster, in order to resolve the power shortage issue Japanese government has established funding to reimburse people who purchased residential energy storage systems. The most important concern for residential energy storage, however, is its safety and cost. The lead acid battery has been dominating in some niche markets for its excellent safety and cost/performance ratio, but its application is also limited by the short cycle life and inability for deep discharge cycling. There has been a new breakthrough of the lead acid battery technology after 150 years – the lead-acid redox flow battery (LARFB). In addition to good safety and C/P ratio, the LARFB is easier to modularize due to its redox-flow-battery structure and is inherently suited for stationary energy storage. However, there are still technological difficulties facing the LARFB, including the short cycle life and relatively high cost. Acknowledging its great potential to be popular in stationary storage market, this research aims to develop the kilowatt-hour scale lead-acid redox flow battery, by which we target the residential energy storage market. There are three directions of research we plan to pursue: (1) increase energy efficiency and extend cycle life of the LARFB; (2) reduce component cost and develop mass-production techniques; (3) scale up and modularize the LARFB. We hope to achieve the goals of cycle life extension, coulomb and energy efficiency increase, and cost reduction of the LARFB after execution of this project. Ultimately, we expect to facilitate commercialization of the LARFB, and in turn to cultivate green industries and promote local production after this effort.液流電池鉛酸家用儲能智慧電網redox flow batterylead acidhome energy storagesmart grid
