Description
Summary:Lithium batteries are receiving considerable attention as storage devices in the renewable energy and sustainable road transport fields. However, low-cost, long-life lithium batteries with higher energy densities are required to facilitate practical application. Here we report a lithium-ion battery that can be cycled at rates as high as 10 C has a life exceeding 500 cycles and an operating temperature range extending from −20 to 55 °C. The estimated energy density is 260 W h kg −1 , which is considerably higher than densities delivered by the presently available Li-ion batteries. Advanced rechargeable lithium-ion batteries have potential applications in the renewable energy and sustainable road transport fields. Jung et al . have developed a lithium battery that uses pre-existing concepts but has highly competitive energy densities, life span and cycling properties.
