Abstract: A gardening apparatus includes a tool device and a battery module. The battery module is coupled to the tool device for supplying power to drive the tool device. The battery module includes a housing with a receiving cavity, at least one battery cell disposed within the receiving cavity, a power management module electrically connected to the at least one battery cell and at least one power interface electrically connected to the power management module and accessible from outside the housing. The power management module is configured to control power flow between the at least one battery cell and the at least one power interface.

Abstract: Described herein are oxygen scavengers, oxygen scavenging polymeric compositions, and oxygen scavenging articles. The polymeric compositions comprising the oxygen scavengers may have utility in packaging, sealing, wrapping, and storing oxygen-sensitive substances, e.g., to preserve freshness of foods, beverages, and the like.
