The clean energy transition requires a co-evolution of innovation, investment, and deployment strategies for emerging energy storage technologies. A deeply decarbonized energy system research platform needs materials science advances in battery technology to overcome the intermittency challenges of wind and solar electricity. Simultaneously, policies designed to build market growth and innovation in battery storage may complement cost reductions across a suite of clean energy technologies. Further integration of R&D and deployment of new storage technologies paves a clear route toward cost-effective low-carbon electricity. Here we analyse deployment and innovation using a two-factor model that integrates the value of investment in materials innovation and technology deployment over time from an empirical dataset covering battery storage technology. Complementary advances in battery storage are of utmost importance to decarbonization alongside improvements in renewable electricity sources. We find and chart a viable path to dispatchable US$1 W⁻¹ solar with US$100 kWh⁻¹ battery storage that enables combinations of solar, wind, and storage to compete directly with fossil-based electricity options.

清洁能源转型需要针对新兴能源存储技术的创新，投资和部署策略共同发展。一个深度脱碳的能源系统研究平台需要电池技术在材料科学方面的进步，以克服风能和太阳能发电的间歇性挑战。同时，旨在建立市场增长和电池存储创新的政策可能会补充一系列清洁能源技术的成本降低。研发的进一步整合和新存储技术的部署为通向具有成本效益的低碳电力铺平了一条清晰的道路。在这里，我们使用两因素模型分析部署和创新，该模型整合了涵盖电池存储技术的经验数据集随时间推移在材料创新和技术部署方面的投资价值。电池存储的补充进步对脱碳以及可再生能源的改善至关重要。我们找到并绘制了可派遣1美元W的可行路径^-1太阳能电池，耗电量100美元/千瓦时^-1电池存储，使太阳能，风能和存储的组合能够直接与基于化石的电力选择竞争。
