摘要： An electrode includes a current collector; a first active material layer including a first active material; and a second active material layer including a second active material; wherein the first active material layer is arranged between the current collector and the second active material layer. The first active material layer is formed on a surface of the current collector, and a particle size of 90% accumulative volume of the first active material is less than 40 μm. The active material layer is used to ensure that the electrochemical device and the electronic device do not generate a short circuit when pressed by an external force, thereby ensuring the mechanical safety performance of the electrochemical device and the electronic device.

摘要： An iron anode employs an electrolyte for generating an anode reaction to convert between Iron II and Iron III ions, denoted by Fe(OH)2 and FeOOH, rather than tending towards formation of highly stable Fe3O4, which can tend to cause “dead” regions in the battery. A suitable battery chemistry includes iron-air and other iron metal batteries operable with an aqueous electrolyte and employing oxygen and water cathodes. The iron anode battery employs inexpensive available iron, rather than more expensive and/or volatile materials used in Li-ion and lead-acid batteries. An aqueous electrolyte formed from sodium hydroxide and silicates, optionally with potassium or chloride salts, forms an anode reaction with nanostructured iron oxide particles in a safe and stable battery chemistry which is readily scalable for grid storage.
