Carboxymethylcellulose and carboxymethylcellulose-formate as binders in MgH2-carbon composites negative electrode for lithium-ion batteries

▶ Carboxymethylcellulose sodium salt and carboxymethylcellulose-formate can be used as binders for MgH2 negative electrode for Li-ion batteries. ▶ These binders help to accommodate the volume variations of metal hydride negative electrode. ▶ These binders improve capacity retention of the MgH2 negative electrode. ▶ Best retention capacity is observed for carboxymethylcellulose-formate binder.
