Silicon anodes promise far higher capacity than graphite but suffer from rapid decay at rest. Researchers evaluate cycling stability and calendar life of micron-sized silicon anodes after tuning electrolytes to form a LiF-rich solid–electrolyte interphase and propose a metric to assess calendar ageing.
