This review discusses efforts to improve lithium battery electrodes at various levels via: (1) the identification of the optimal chemical composition of active materials (AMs), (2) tailoring physical properties of AMs such as size and surface, and (3) integrating AMs with binders, conductive additives, and current collectors.
While much progress is being made to improve LIBs, other battery chemistries such as lithium–sulfur batteries (LSBs), Al-ion, Na-ion, and K-ion are also being explored [ 8, 9, 10, 11, 12, 13, 14 ]. In this short review, recent progress in improving the electrochemical performance and cycle life of lithium batteries is presented.
The adoption of electrification in vehicles is considered the most prominent solution. Most recently, lithium-ion (li-ion) batteries are paving the way in automotive powertrain applications due to their high energy storage density and recharge ability (Zhu et al., 2015).
However, there has been limited research that combines both, vibration and temperature, to assess the overall performance. The presented review aims to summarise all the past published research which describes the parameters that influence performance in lithium-ion batteries.
An automotive lithium-ion battery pack is a device comprising electrochemical cells interconnected in series or parallel that provide energy to the electric vehicle. The battery pack embraces different systems of interrelated subsystems necessary to meet technical and life requirements according to the applications (Warner, 2015).
However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.
