Trade‐off between energy density and fast‐charge capability of lithium ...
1 INTRODUCTION. Lithium-ion batteries exhibit a well-known trade-off between energy and power, often expressed as the power-over-energy (P/E) ratio, [] and typically represented in a so-called Ragone plot of power as a function of energy. [] This trade-off is problematic for electric vehicle (EV) batteries: On the one hand, a high driving range is desired, …
Hvordan fungerer litiumholdige batterier?
- Litium-ionbatteriene har den høyeste energitettheten av alle oppladbare batterier. Energien et batteri kan levere, er gitt av produktet av cellespenningen og hvor mye lading som lagres i elektrodene. Litium-ionbatterier kan gi en spenning på rundt 3,5–4 V, som er mye høyere enn konvensjonelle batterier som f.eks. blybatterier.
