"blending silicon (stores roughly 10X more lithium than graphite)/ graphite electrodes doubles lifetime utilizing adaptive heating/ cooling during charging... charge threshold where fragile silicon begins working hardest shifts as battery ages, rendering standard, fixed temperature controls ineffective over time... using advanced diagnostic algorithms, voltage data pinpoints threshold in real time, warming when silicon active/ cooling when graphite takes over... high-capacity silicon/ graphite anode commercialization"
