Upscaling of Fast Charging Strategies from Coin to Pouch Cells The formation of lithium-ion batteries is one of the most time-consuming processes during the cell production. Common formation methods consist of several relatively slow constant charging and discharging cycles as it is believed to guarantee good performance of the Solid Electrolyte Interphase (SEI) on the […]

This study brings a novel irreversible capacity-elimination method that cleverly utilizes waste graphite to develop a process for fabricating micron-thin, free-standing, and hosted metallic lithium films. We have demonstrated its pre-lithiation application in NCA622||CG-Si full cell. The infusion of molten metallic lithium into graphene oxide host tunable micrometer-scale thickness yields an ultra-thin Li@GO film. The […]

Solid-state batteries are next-generation energy storage systems that potentially can overcome the limits of conventional Li-ion batteries with respect to their energy density and by providing higher safety. From a materials perspective, sulfide-based solid electrolytes (SE) and cathode active materials (CAM) such as LiNixCoyMn1-x-yO2 (NCM) are considered as promising candidates to be employed in solid-state […]

The market for lithium-ion batteries is growing, and customised and optimised cell con-cepts are becoming increasingly important. Different cell design requirements can be evaluated at an early stage in the development of prototypes for application-specific cell concepts such as high energy and high power cells. One method is numerical simulation, which uses mathematical and physical […]

With the phasing out of internal combustion engine vehicles from 2035 in the EU, battery electric vehicles (BEV) are becoming more in focus to achieve an important step towards a zero-emission transportation sector. Current challenges for BEVs are fast-charging capabilities and safety as well as range is a much-discussed topic. One way to increase the […]

Electrochemical Impedance Spectroscopy (EIS) is a method used for estimating the power delivery capability and state of health (SoH) through the estimation of the battery impedance. Since EIS is a pure observational analytical method and doesn’t require the disassembly of the battery, research activities around the world are moving from pure laboratory studies to implementation […]

With the ever-increasing demand for new and improved battery materials, efficient characterization methods to obtain precise insights into both raw materials and fully assembled batteries are more important than ever. Since most modern battery materials are crystalline, and the crystallinity and crystal structure can have significant influence on a material’s performance, X-ray diffraction (XRD) is […]

The need for batteries with improved performance compared to conventional Li-ion technologies is rapidly growing. The capacity, charging speed, and stability of the batteries required for future technologies such as electric cars and renewable energies are continuously improved. At the same time, the cost and the time for battery production must be reduced to satisfy […]

At the Advanced Battery Power conference, we present the findings of the COBRA project, which is part of the European Union’s Horizon 2020 program. The objective of this project is to develop an innovative cobalt-free Li-ion battery technology to overcome the constraints of current electric vehicle batteries. Our approach focuses on enhancing the safety aspects […]
