Electric Vehicles (EVs) play a critical role in our formidable task of transitioning towards a low-carbon economy. The global EV market continues to grow at a rate that is faster than ever before. (now ~$250 billion and projected a four-fold expansion by 2027) This rapid growth drives rising demand for safe and robust batteries that can deliver more energy in a limited physical size. Conventional lithium-ion batteries that dominate the EV market use carbonate-based liquid electrolytes that are flammable and prone to volume expansion, posing severe safety hazards. Equally importantly, additional packing accessories are required to prevent electrolyte leakage, limiting the maximum energy and power a battery can ultimately deliver per unit volume. Replacing liquid-electrolyte with solid will enable smaller batteries with higher energy density and improved safety, key features to support long-distance driving and heavy-duty vehicles. (e.g., e-trucks and e-buses) Driven by the EV market growth, the solid-state battery market also expects an approximately four-fold expansion by 2027, projecting tremendous opportunities. This program will develop a printable, mechanically enhanced hybrid electrolyte membrane (HEM) that enables the cost-effective manufacturing of safe, high-energy solid-state lithium batteries. HEM exhibiting the same performance does not yet exist in the current market. In this 2-year AI-supported program, our team will synthesize the HEM by integrating our recently discovered air-stable ceramic conductor with a "mechanical strengthen agent" - a polymeric additive derived from local industrial byproducts. These activities will prepare our initial group of products for commercialization at TRL 4 (expected in 24 months). Beyond, we aim to develop a market-orientated business expansion plan towards solid-state battery prototypes with our existing and new partners - the end-users. (i.e., Toyota, GM, Tesla, etc.) This program will also serve as a training platform for the next-generation R&D experts leading the local solid-state battery industrial sector grown from this initiative.

电动汽车（EV）在我们过渡到低碳经济的艰巨任务中起着至关重要的作用。全球电动汽车市场的增长速度比以往任何时候都要快。 （现在约为2500亿美元，预计到2027年进行了四倍的扩展）这种快速增长促使人们对安全和强大的电池的需求不断上升，这些电池的需求可以在有限的物理尺寸中提供更多的能量。主导电动汽车市场的常规锂离子电池使用碳酸盐基液体电解质，可易燃且容易扩大体积，从而带来严重的安全危害。同样重要的是，需要其他包装配件来防止电解质泄漏，从而限制了电池最终可以输送每单位体积的最大能量和功率。用固体代替液体电解质，将使能量密度较高和安全性提高的较小电池，支持长距离驾驶和重型车辆的关键功能。 （例如，电子卡车和电子车）在电动汽车市场增长的驱动下，固态电池市场也预计到2027年将有大约四倍的扩展，这会有巨大的机会。该程序将开发可打印的，机械增强的混合电解质膜（HEM），以实现安全，高能量固态锂电池的成本效益。在当前市场中尚不存在表现出相同性能的下摆。在这个为期两年的AI支持的计划中，我们的团队将通过将我们最近发现的空气稳定陶瓷导体与“机械增强剂”（一种来自当地工业副产品衍生的聚合物添加剂）相结合来综合下摆。这些活动将为我们在TRL 4（预计24个月内）的最初产品组成产品准备。除了之外，我们旨在与现有和新合作伙伴 - 最终用户制定面向市场的业务扩展计划，以针对固态电池原型。 （即，丰田，通用汽车，特斯拉等）该计划还将作为下一代研发专家的培训平台，领导该计划发展的当地固态电池工业部门。
