An electrochemical battery cell of a lithium ion battery has a physically cross-linked gel electrolyte situated between a negative electrode and a positive electrode. The gel electrolyte includes a block co-polymer host and a liquid electrolyte, which can transport lithium ions, absorbed into the block co-polymer host. The block co-polymer host includes poly(alkylene oxide) block units and physically cross-linkable block units. A few preferred physically cross-linkable block units that may be employed include polyamide block units and poly(terephthalate)ester block units. |
