    Abstract: Provided herein are novel template electrode materials and structures for lithium ion cells. Related methods are also provided. According to various embodiments, an electrode can include a nanostructured template, an electrochemically active material layer coating the template, and a first intermediate layer between the nanostructured template and the electrochemically active material layer. In one arrangement, the nanostructured template includes silicide nanowires. The electrochemically active material may be any of silicon, tin, germanium, carbon, metal hydrides, silicides, phosphides, and nitrides. The first intermediate layer may facilitate adhesion between the nanostructured template and the electrochemically active material layer, electronic conductivity within the electrode, and/or stress relaxation between the nanostructured template and the electrochemically active material layer.

    Abstract: The present invention provides a method for treating silicon to form pillars ( see Figure 2), especially for use as the active anode material in Li-ion batteries. The process is simple to operate on a commercial scale since it uses a solution containing only a small number of ingredients whose concentration needs to be controlled and it can be cheaper to operate than previous processes. The etching solution comprises: 0.01 to 5M HF 0.002 to 0.2M of metal ions capable of nucleating on and forming a porous layer comprising regions of elemental metal on the silicon surface; 0.001 to 0.7M of an oxidant selected from the group O2, O3, H2O2, the acid, ammonium or alkali metal salt of NO3 -, S2O8 2-, NO2 -, B4O7 2- and ClO4 - a mixture thereof. The treated silicon is suitably removed from the solution. Etched particles or fibres made by the process may be used in the form of a composite material in the active electrode material.

    Abstract: In a process of producing a porous layer of electrolytically depositable metal a support material (1) is immersed in an electrolytic medium (2) comprising ions of the metal and the metal is electrolytically deposited onto the support material (1) in the presence of an oxidising species which reacts with the metal to form a product which is reducible under the deposition conditions. In one form of process, a metal is deposited onto a support material (1) from an aqueous medium comprising ions of the metal, oxygen being introduced into the medium to pass in the vicinity of the support material. The process enables highly porous metal to be manufactured. The porous metal obtained is useful as catalytic material or as electrode material.

    Abstract: A rechargeable electrochemical device comprising an anode (6) composed chiefly of activated carbon, cathode (3) composed of a lithium alloy, and an electrolyte composed of an organic solvent in which a lithium salt is dissolved. Lithium content in the lithium alloy forming the cathode (3) is selected such that, if converted to the electric capacity under the charged condition, the capacity of this alloy ranges from 3 to 20 times the anode capacity that is obtained when the anode is discharged from 3.0 V to 2.0 V in a single-pole potential with respect to metal lithium. This constitution is able to provide a reliable rechargeable electrochemical device, which is proof against super-discharge and excellent in charge and discharge cycle life.
