Abstract

Environmentally friendly materials and processes are needed for the sustainable development of batteries [1]. The efforts on going at HIU are briefly presented.

The aqueous processing of lithium-ion battery (LIB) electrodes has the potential to notably decrease the battery processing costs and paves the way for the sustainable production (and recycling) of electrochemical energy storage devices. In this study, we show that the addition of small quantities of phosphoric acid into the cathodic slurry yields Li[Ni0.33Mn0.33Co0.33]O2 electrodes that have an outstanding electrochemical performance in lithium-ion cells [2].

Another example is the excellent performance of graphite//LiNi0.5Mn1.5O4 (LNMO) cells with both electrodes made using water-soluble sodium carboxymethylcellulose (CMC) binder [3]. The full cell performed outstandingly over 400 cycles in the conventional electrolyte ethylene carbonate/dimethyl carbonate–1M LiPF6, with an initial energy value of 259 Wh kg-1 referred to the sum of the two electrode-composite weights.

The sustainable use of natural resources is indispensable for future energy storage. As a step towards the utilization of biowaste, hard carbon produced from waste apples is demonstrated to be a high performance active material for Na-ion batteries [4,5]. Full Na-ion cells based on sustainable materials and environmentally-friendly electrode making processes are also demonstrated.
