Sodium-ion　batteries　have　been　developing　rapidly　in　recent　years　due　to　abundant　sodium　resources.　Organic　polymers　and　their　derived　carbon　materials　are　abundant　in　resources,　with　small　environmental　footprint　and　controllable　structural　design,　and　can　be　directly　used　in　the　positive　and　anode　of　sodium　ion　batteries,　which　is　of　great　significance　for　green　and　sustainable　development.　Organic　polymers　also　offer　great　advantages　in　flexible　Sodium-ion　batteries　due　to　their　inherent　flexibility.　The　research　progress　of　flexible　organic　polymer　materials　and　flexible　polymer　derived　carbon　materials　in　sodium　ion　batteries　are　reviewed.　Among　them,　flexible　organic　polymer　materials　will　be　divided　into　flexible　organic　polymer　carbonyl　molecules　and　their　composites　with　graphene/carbon　nanotubes.　For　polymer-derived　carbon　materials,　we　will　introduce　several　different　precursors　and　preparation　methods.　Perspectives　are　envisioned　for　the　further　development　of　flexible　renewable　polymer　materials.
