The goal of this research project is to develop a novel printed lithium-ion battery process that can be integrated**with a solar panel. Our industrial partner SolarGrid Energy Inc. (SGE) manufactures solar street lights that**contain a solar panel, a battery, an LED light and the required electronics. Currently, SGE is constrained by the**battery technology on the market that is not optimized for this application in terms of weight,**manufacturability, performance and safety. We propose to create a battery printing process that can be**integrated into SGE's current solar panel assembly process with relatively few modifications. This will ensure**SGE's requirements are met and that SGE can exploit the research results in their manufacturing process. The**printed battery can be inserted in the solar panel in between the silicon solar cells and the back encapsulation.**This saves weight because no separate encapsulation is needed for the battery. We will employ screen printing**as a proven, cheap, simple and scalable manufacturing technology. We will implement state-of-the-art Li-ion**battery concepts for the first time in a printed battery including a novel solid-state electrolyte and an anode-free**structure. These concepts will ensure that we meet SGE's requirements in terms of performance, durability and**safety. We will study the printed batteries in terms of electrical performance and microstructure. We will focus**on the electrolyte and its interfaces as a particularly critical component of the battery structure. This will be**optimized to ensure good cycle lifetime. Throughout the project, we will be in constant contact with our**partners at SGE to ensure that our processes and devices are compatible with their products and manufacturing**processes. The final report will form the basis for SGE to take a decision on whether to pursue a follow-on**research project and ultimately integrate the novel printed battery in their products. If successful, the results of**this project will help SGE maintain and expand their position in the growing market for smart green energy**generation and storage.

该研究项目的目标是开发一种可与太阳能电池板集成**的新型印刷锂离子电池工艺。我们的工业合作伙伴 SolarGrid Energy Inc. (SGE) 生产太阳能路灯，**包含太阳能电池板、电池、LED 灯和所需的电子设备。目前，SGE 受到市场上**电池技术的限制，该技术在重量、**可制造性、性能和安全性方面并未针对该应用进行优化。我们建议创建一种电池印刷工艺，只需相对较少的修改即可集成到 SGE 当前的太阳能电池板组装工艺中。这将确保**SGE 的要求得到满足，并且 SGE 可以在其制造过程中利用研究成果。 **印刷电池可以插入太阳能电池板中的硅太阳能电池和背面封装之间。**这可以减轻重量，因为电池不需要单独的封装。我们将采用丝网印刷**作为一种经过验证、廉价、简单且可扩展的制造技术。我们将首次在印刷电池中实施最先进的锂离子**电池概念，包括新型固态电解质和无阳极**结构。这些概念将确保我们在性能、耐用性和**安全性方面满足 SGE 的要求。我们将从电气性能和微观结构方面研究印刷电池。我们将重点关注电解质及其界面，作为电池结构中特别关键的组成部分。这将被优化以确保良好的循环寿命。在整个项目过程中，我们将与 SGE 的**合作伙伴保持联系，以确保我们的流程和设备与其产品和制造**流程兼容。最终报告将成为 SGE 决定是否开展后续研究项目并最终将新型印刷电池集成到其产品中的基础。如果成功，**该项目的成果将帮助 SGE 保持并扩大其在不断增长的智能绿色能源**发电和存储市场中的地位。
