## Abstract

The invention relates to a liquid storage method and storage devices. The method involves liquid storage with porous materials. The storage devices in different shapes are made of the porous materials, and liquids are stored in pores. The method and devices for storing liquids avoid assembling, and feature automated operation and short delivery. The porosity of a porous material of the same volume can be adjusted according to demands on liquid stock. After being absorbed, liquids do not spill over, and the devices do not feel wet when touched with hands and have an obvious anti-leak effect. The devices can be molded in diversified shapes, and are low in cost. The materials are environmentally-friendly and degradable. When storing a liquid of the same volume, the porous materials are small in size, light in weight and capable of saving transport expenses.

## Claims
