abstract = {Ni-rich layered oxide cathodes are promising candidates to
satisfy the increasing energy demand of lithium ion
batteries for automotive applications. Aqueous processing of
such materials, although being desirable to reduce costs and
improve sustainability, remains challenging due to the Li +
/H + -exchange upon contact with water, resulting in a pH
increase and corrosion of the aluminum current collector.
Herein, an example for tuning the properties of aqueous LiNi
0.83 Co 0.12 Mn 0.05 O 2 electrode pastes using a lithium
polyacrylate-based binder to find the “sweet spot” for
processing parameters and electrochemical performance is
given. Polyacrylic acid is partially neutralized to balance
high initial capacity, good cycling stability and the
prevention of aluminum corrosion. Optimized LiOH/polyacrylic
acid ratios in water are identified, showing comparable
cycling performance to electrodes processed with
polyvinylidene difluoride requiring toxic
N-methyl-2-pyrrolidone as solvent. This work gives an
exemplary study for tuning aqueous electrode pastes
properties aiming towards a more environmentally friendly
processing of Ni-rich cathodes.},
