IntroductionIntroductionModern societies depend on reliable supplies of electricity, readily available at the location and time it is needed,fo

46、r everything from heating, lighting, cooking and entertainment to industrial and medical equipment and, increasingly, transport. Yet electricity is unlike other fuels that we use every day, because almost all the electricity needed is generated just moments beforehand. This is because it is expensiv

47、e and difficult to store in large quantities over the past century, storage has largely been limited to pumping water to uphill reservoirs to create a reserve supply of power for use during shortages.As a crucial energy carrier for a low-carbon energy system, electricity has a number of key advantag

48、es: it can be readily generated from renewable sources, such as solar and wind, it does not produce any emissions at the point of use, and it is extremely versatile in its applications. In theory, it can be used for any energy service, and improvements to devices like heat pumps are making it even m

49、ore competitive.However, it also has some major drawbacks, which are currently being addressed by technology innovators. First, to make use of solar and wind power, which are key renewable energy sources for the future, the sun needs to be shining and the wind needs to be blowing, and thetimes at wh

50、ich this happens may not be well matched with demand. Second, existing ways of storing electricity to decouple the time of generation from the time of use are not appropriate or cost-effective for all situations. Batteries provide a flexible solution that allows electricity to be used without being

51、connected to the power grid, but they remain a generally heavy and costly option for storing energy on board vehicles, especially trucks and aircraft.Aim of the studyBetter batteries and other energy storage technologies can open up opportunities to replace unabated fossil fuels in a variety of end-

52、use applications and integrate more renewable energy into the energy system (International Energy Agency (IEA), 2019a; IEA, 2020a). Low-cost, reliable, responsive electricity storage with a high power outputcan also have a positive impact on power grid management costs and reduce the need for synchr

53、onous generators that regulate electricity frequency and are usually powered by fossil fuels.These trends and needs help to explain the rapid and sustained increase in innovation in batteries documented by this report. Aimed at decision-makers in both the private and the public sector, this report i

54、s a unique source of intelligence on the innovation trends behind batteries, drawing on the latest information available in patent documents and the combined expertise of IEA analysts and European Patent Office (EPO) examiners.Patent information provides robust statistical evidence of technical prog

55、ress, as companies and inventors make use of the temporary exclusivity conferred by patent rights to market their innovations and, in doing so, recoup their research and development (R&D) investments. The datapresented offer insights into which countries and companies are leading the way in the deve

56、lopment of electricity storage technologies and are therefore likely to be well placed to deliver much-needed improvements in this area in the near future. In addition, the data show how the types of electricity storage application attracting the most interest from companies and inventors have chang

57、ed, as well as which applications and technologies are gathering momentumand could be poised to play breakthrough roles in the future.Whats more, trends in electricity storage patenting are particularly relevant given the current circumstances. As the impact of the Covid-19 pandemic is felt across t

58、he world, with many countries facing an uncertain economic future over the next few years, governments are looking to boost scalable, clean and technology-intensive sectors (IEA 2020b). Electricity storage, and battery technology in particular, is one such technological area (IEA, 2020c). Indeed, su

59、pport for electricity storage was high in the United States following the financial crisis, with the government allocating economic stimulus funds to the area in 2009-2012. Patent data can help to inform governments about their comparative advantage at different stages of a technologys value chain a
