CEA-Leti has come up with a way to allow RRAM devices to operate as energy-storage elements as well as memory, depending on the applied bias. In-memory energy is a supplemental feature to in-memory computing which can reduce energy use because RRAM-based batteries are scalable and dynamically allocable, and can be placed next to memory blocks, ...

Argonne National Laboratory has been looking into lithium-ion cells in great detail, and its scientists have found a nano-scale deterioration mechanism to add to the reasons that fast-charged Li-ion batteries degrade in electric vehicles. In use, lithium ions move in and out of the anode, which is usually made from graphite particles. The ions slide ...
