Models for Battery Reliability and Lifetime

Stochastic Ageing and Dependence for Reliability

Ageing and dependence are two important characteristics in reliability and survival analysis, and they affect significantly the decision people make with regard to maintenance, repair/replacement, price setting, warranties, medical studies, and other areas. There are many papers published at different technical levels. This book aims at providing a state-of-the-art review of the subject so the ...

How Electrolytes Influence Battery Safety

45 (continued on next page) Lithium batteries use organic electrolytes because of the wide operating voltage. For lithium ion rechargeable batteries, these electrolytes are almost universally based on combinations of linear and cyclic alkyl carbonates. These electrolytes make possible the use of Li as the anodic active component and results in the high power and energy densities characteristic ...
