通讯员 据油价网2021年3月1日伦敦报道，基于美国的工程师们日前已联手开发用于仪表后（BTM）储能应用的高压参考电池，高压参考电池基于在传统铅电池中使用硅片的双极技术。
这种晶片类似于光伏电池中的晶片，其理念是开发一种“即插即用”的太阳能储能系统。
这种双极技术被称为硅焦耳（Silicon Joule），由Gridtential能源公司开发，其目标是减轻铅电池的重量，并在成本更低的情况下实现与锂离子电池的性能竞争。
与Gridtential能源公司一起，这个项目由电气应用公司(EAI)和电池创新联盟(CBI)共同推进。
这项研究合作将涉及使用硅焦耳双极电池构建微型系统进行测试，EAI将开发一种优化的充电方案，以复制现实生活中的能量储存系统。
另一方面，CBI将提供其旨在最大化循环寿命和能源吞吐量的技术路线图，这是可再生能源储存的两个关键技术参数。
BTM能源储存是脱碳领域的一个关键部分。伍德麦肯兹预计，仅在美国，2020年已安装的BTM能源储存就达到430兆瓦，比2019年增加了100%以上。这推动了对价格合理、安全、高性能的电池的需求，这些电池易于连接，为住宅市场提供可再生能源。

New Battery Tech Could Make Solar Energy Storage Even Cheaper
US-based engineers have joined forces to develop high-voltage reference batteries for behind-the-meter energy storage applications, based on a bipolar technology that uses silicon wafers in traditional lead batteries.
The wafers are similar to those in photovoltaic cells and the idea is that the development becomes a ‘plug and play’ solar-powered energy storage system.
The bipolar technology is known as Silicon Joule and has been developed by Gridtential Energy with the goal of reducing lead batteries’ weight and achieving a performance competitive with that of lithium-ion batteries but at a lower cost.
Together with Gridtential, the project is being advanced by Electric Applications Incorporated (EAI) and the Consortium for Battery Innovation (CBI).
The research collaboration will involve building mini-systems using Silicon Joule bipolar batteries for testing, with EAI developing an optimized charge scheme to
replicate real-life energy storage systems.
The CBI, on the other hand, will provide its technical roadmap to maximize cycle life and energy throughput – two key technical parameters for renewable energy storage.
“Behind-the-meter (BTM) energy storage is a critical piece for the decarbonization. In the US alone, Wood Mackenzie predicted 430 MW installed in 2020, reflecting an increase of more than 100% over 2019,” the companies said in a media statement. “This is driving the need for affordable, safe, high-performing batteries in easy-to-connect packages that incorporate renewable energy for the residential market.
