More on the 3000 mile battery

[Old Rocks]

This is the paper that outlines the possibility of creating batteries that could give an EV 3000 miles range. A highly technical paper, with a though analysis of the working of the battery. Here is the conclusion of the paper;

3 Conclusion​

"In summary, an in situ interlocking electrode–electrolyte system is proposed to enhance the stability and performance of QSSBs with SiMP anodes and NCM811 cathodes. Achieved through covalent crosslinking between acrylate groups on a designed IB and a crosslinker within the QSSE, the IEE system creates a robust, interconnected network that effectively mitigates mechanical degradation and maintains stable interfacial contact throughout cycling. Compared to traditional LE and QSSE configurations, which suffer from severe capacity decay due to SiMP pulverization, high interfacial resistance, and unstable SEI formation, the IEE system effectively mitigates these challenges, enabling high capacity retention and stable cycling performance. Notably, the SiMP half cell with the IEE system retained 81.3% of its capacity over 200 cycles, and the SiMP||NCM811 full cell achieved rapid CE stabilization at 99.5% within three cycles. The bi-layer pouch cell configuration further demonstrated the scalability of the IEE system, delivering a high energy density of 403.7 Wh kg−1/1300 Wh L−1 and enhanced safety under mechanical abuses, underscoring its potential for high-energy-density and durable energy storage applications."
