Kampala, Uganda has the 17th worst air pollution in the world, with an abundance of motorcycles contributing with unregulated emissions. 75% of Ugandans are rural farmers, living off of subsistence farming with energy access rates below 10%. Meanwhile, the two-wheeled EV (2WEV) market is taking off in the region, poised to help reduce air pollution but introducing a looming e-waste problem caused when their lithium-ion batteries reach the end of their service life.Taken separately, these are problems. But together they represent an opportunity to turn e-waste into e-resources, increase energy access and agricultural productivity, and boost the uptake of clean energy solutions. To this end, Soleil Power and STI4D are implementing a project to build high-quality 2WEV batteries designed for efficient repurposing into affordable and scalable 2nd-life products for energy access customers. We want to get ahead of the curve by enabling a circular battery value chain right from the start.Li-Ion batteries have a long total life-span but they are removed from EV service once they are depleted to 80% of their original capacity. Thereafter, whilst they are no longer optimal for EV use, they still have very high potential value in stationary applications such as mini-grids and institutional ESS. To capture this value, STI4D and Soleil will also design affordable 2nd-life products that can be deployed off-grid or as backup-power.Soleil will build on existing partnerships to test these innovative products. E-mobility company Zembo, building 2WEVs and battery swapping/charging infrastructure, sees high value in procuring their batteries domestically as well as having a partner to offtake them after they have completed their service. E-Ag partner Regenerators, who are working to increase smallholder productivity through the introduction of an electric tractor will also pilot the EV battery.Soleil's experience shows that much of the cost associated with the repurposing of EV battery products depends on the complexity of disassembly, testing and rebuilding used battery-modules. The new designs will streamline and accelerate this process to reduce e-waste and facilitate circularity whilst increasing access to clean and affordable energy. A better understanding of the battery circular economy in East Africa is critical to finding optimal ways to incentivize commercial investment, so STI4D and Soleil will also use the project as a case study on which to conduct a value-chain analysis, developing and collecting data on sustainable business models including for combining energy access systems with battery-charging as anchor loads.

乌干达坎帕拉的空气污染在世界上排名第17，有大量的摩托车排放不受管制的废气。75%的乌干达人是农村农民，以自给自足的农业为生，能源获得率低于10%。与此同时，两轮电动汽车(2WEV)市场在该地区正在腾飞，有望帮助减少空气污染，但当锂离子电池的使用寿命即将结束时，会带来迫在眉睫的电子垃圾问题。分开来看，这些都是问题。但它们共同代表着将电子垃圾转化为电子资源的机会，增加能源获取和农业生产率，并促进采用清洁能源解决方案。为此，Soleil Power和STI4D正在实施一个项目，以制造高质量的2WEV电池，旨在高效地重新利用，成为面向能源接入客户的负担得起且可扩展的第二生命产品。我们希望从一开始就实现循环的电池价值链，从而走在曲线的前面。锂离子电池的总寿命很长，但一旦耗尽到原始容量的80%，它们就会退出电动汽车服务。此后，尽管它们不再是电动汽车使用的最佳选择，但它们在微型电网和机构ESS等固定应用中仍具有非常高的潜在价值。为了抓住这一价值，STI4D和Soleil还将设计负担得起的第二生命产品，这些产品可以离网部署或作为后备电源。Soleil将建立现有的合作伙伴关系来测试这些创新产品。制造2WEV和电池交换/充电基础设施的电子移动公司Zembo认为，在国内采购电池以及在完成服务后有合作伙伴接替电池具有很高的价值。致力于通过引入电动拖拉机来提高小农生产率的E-Ag合作伙伴再生器公司也将试行电动汽车电池。Soleil的经验表明，与重新调整电动汽车电池产品用途相关的大部分成本取决于拆卸、测试和重建旧电池模块的复杂性。新的设计将简化和加快这一进程，以减少电子垃圾，促进循环，同时增加获得清洁和负担得起的能源。更好地了解东非的电池循环经济对于找到激励商业投资的最佳方式至关重要，因此STI4D和Soleil还将以该项目为案例进行价值链分析，开发和收集可持续商业模式的数据，包括将能源获取系统与电池充电相结合作为锚定负载。
