Sodium trisilicate waterglass is an earth-abundant inorganic adhesive which binds to
diverse materials and exhibits extreme chemical and temperature stability. Here we
demonstrate the use of this material as an electrode binder in a lay-up based manufacturing
system to produce structural batteries. While conventional binders for structural batteries
exhibit a trade-off between mechanical and electrochemical performance, the waterglass
binder is rigid, adhesive, and facilitates ion transport. The bulk binder maintains a Young's …
