“…[1][2][3] Despite revolutionising the portable electronics industry, current Li-ion batteries cannot meet the requirements of next-generation technologies and incremental improvements in their performance will not be sufficient in bridging the gap between current and future energy storage demands. [4][5][6][7] To achieve the transformational improvements in energy and power densities, cost, safety and lifetime required for future power-hungry applications, it is necessary to look beyond traditional Li-ion battery technologies to promising alternative battery architectures with the potential for radical enhancements in performance. [8][9][10][11] One such example architecture is the solid-state battery, 8,[12][13][14][15] which relies on solid electrolytes and the fast ion conduction they deliver.…”

“…Lithium-ion batteries (LIBs) have been widely applied in energy storage applications, especially in personal portable electronic devices, due to their high energy density, long cyclic stability, and good safety [ 1 , 2 , 3 , 4 , 5 ]. Despite the huge success and continuous growing specific energy at 6%/year [ 6 ], there are still several technical challenges for the application of LIBs in automotive industries in order to meet or exceed the requirements compared to conventional vehicles with internal combustion engines, such as long cycle life (>500 cycles), a calendar life >10 years, and stability at different temperatures ranging from −30 to 52 °C [ 7 ]. The production costs of LIBs, currently about 250 USD/kWh, still limit their widespread use in the automobile industry and should be reduced to below 125 USD/kWh [ 7 , 8 ].…”

Characterization and Laser Structuring of Aqueous Processed Li(Ni0.6Mn0.2Co0.2)O2 Thick-Film Cathodes for Lithium-Ion Batteries

Lithium-ion batteries have led the revolution in portable electronic devices and electrical vehicles due to their high gravimetric energy density. In particular, layered cathode material Li(Ni0.6Mn0.2Co0.2)O2 (NMC 622) can deliver high specific capacities of about 180 mAh/g. However, traditional cathode manufacturing involves high processing costs and environmental issues due to the use of organic binder polyvinylidenfluoride (PVDF) and highly toxic solvent N-methyl-pyrrolidone (NMP). In order to overcome these drawbacks, aqueous processing of thick-film NMC 622 cathodes was studied using carboxymethyl cellulose and fluorine acrylic hybrid latex as binders. Acetic acid was added during the mixing process to obtain slurries with pH values varying from 7.4 to 12.1. The electrode films could be produced with high homogeneity using slurries with pH values smaller than 10. Cyclic voltammetry measurements showed that the addition of acetic acid did not affect the redox reaction of active material during charging and discharging. Rate capability tests revealed that the specific capacities with higher slurry pH values were increased at C-rates above C/5. Cells with laser structured thick-film electrodes showed an increase in capacity by 40 mAh/g in comparison to cells with unstructured electrodes.

Li-ion batteries are widely used in electric vehicles because of their promising characteristics that meet high specific power and energy density requirements. The only setback is the capacity fading due to degradation in Li-ion batteries. The rate of capacity fade in Li-ion batteries in EVs vary based on the charging rate, changes in internal cell temperature and external ambient temperature, and user driving patterns. Since the Li-ion battery is electrochemical, determining the actual cause of degradation at a particular instant and constraining the rate is a big challenge. Further, the causes are related to parameters which are chemical, electrical and mechanical. In this work, the causes of degradation are studied by analysing the variation of parameters for multiple charge types and rates at different ambient temperatures. The analysis leads to developing a new battery friendly charging scheme suitable to fast charge battery at different ambient temperatures appropriately and constrain battery degradation.
