Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Development of lithium-ion batteries suitable for high temperature applications requires a holistic approach to battery design because degradation of some of the battery components can produce a serious deterioration of the other components, and the products of degradation are often more reactive than the starting materials.
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives. The breakthroughs of electrode materials are on the way for next-generation batteries.
Therefore, employing additives to improve the low-temperature performance of LIBs is an effective strategy, which has drawn tremendous research interests in past decades. 43 The additives are mostly film-forming additives, which hold the ability to reduce film resistance and optimize lithium salt deposition behavior.
The performance of lithium iron phosphate is improved at higher temperatures with the increase in rate capability and increase in capacity. [10,11] LFP has shown to be effective as a stable positive electrode material up to 250 ËšC, as can be seen in table 1.
