摘要:
An electrode for a lithium ion battery includes a matrix based on at least one polysaccharide and also particles of at least one electrochemically active material which are embedded in the matrix, with the electrode being free of synthetic polymeric compounds. A battery contains the electrode and a polysaccharide is a binder for electrochemically active electrode materials for such an electrode.
摘要:
in a method and a device for placing units, such as motes, for executing an application in a distributed system, a placement of the units by a service layer and a communication between the units by a communication layer are provided. One field of application is for example process automation, such as in industrial or building management installations. Such installations have sensors and actuators with communication interfaces. The method and the device allow the energy demand of the installation to be reduced. Communication is preferably performed wirelessly. Network management is for example conducted according to the wireless HART protocol.
