The invention discloses a powder off prevention battery grid suitable for a rolling brush process. The powder off prevention battery grid comprises a lug and grid bodies, wherein an active substance is coated on each grid body, a grid plane with lattices is arranged on the grid body, a bending edge is arranged around the grid plane, and a part where the bending edge and the grid plane are connected is bent. Lead powder is prevented from separating from the grid body by a bending structure during charging and discharging, thus, the lead powder is effectively prevented from being deposited at the bottom of a battery shell, the problem of pole plate short circuit caused by excessive deposition of the lead powder is avoided, the service lifetime of a storage battery is greatly prolonged, and the application safety of the storage battery is improved.
