    Abstract: A multi-electrolyte battery, that may include an anode, a cathode, a solid electrolyte positioned between the anode and the cathode, current carriers that comprises an anode current carrier and a cathode current carrier; and at least one other electrolyte. The anode current carrier and the cathode current carrier comprise two external portions that extends outside the anode. The solid electrolyte is sealingly coupled to the two external portions of at least one of the current carriers to define at least one sealed electrolyte, the at least one sealed electrolyte belongs to the at least one other electrolyte.

    Abstract: Electrodes, production methods and mono-cell batteries are provided, which comprise active material particles embedded in electrically conductive metallic porous structure, dry-etched anode structures and battery structures with thick anodes and cathodes that have spatially uniform resistance. The metallic porous structure provides electric conductivity, a large volume that supports good ionic conductivity, that in turn reduces directional elongation of the particles during operation, and may enable reduction or removal of binders, conductive additives and/or current collectors to yield electrodes with higher structural stability, lower resistance, possibly higher energy density and longer cycling lifetime. Dry etching treatments may be used to reduce oxidized surfaces of the active material particles, thereby simplifying production methods and enhancing porosity and ionic conductivity of the electrodes. Electrodes may be made thick and used to form mono-cell batteries which are simple to produce and yield high performance.

    Abstract: Lithium ion batteries and electrolytes therefor are provided, which include electrolyte additives having dithioester functional group(s) that stabilize the SEI (solid-electrolyte interface) at the surfaces of the anode material particles, and/or stabilize the CEI (cathode electrolyte interface) at the surfaces of the cathode material particles, and/or act as oxygen scavengers to prevent cell degradation. The electrolyte additives having dithioester functional group(s) may function as polymerization controlling and/or chain transfer agents that regulate the level of polymerization of other electrolyte components, such as VC (vinyl carbonate) and improve the formation and operation of the batteries. The lithium ion batteries may have metalloid-based anodes—including mostly Si, Ge and/or Sn as anode active material particles.

    Abstract: Improved anodes and cells are provided, which enable fast charging rates with enhanced safety due to much reduced probability of metallization of lithium on the anode, preventing dendrite growth and related risks of fire or explosion. Anodes and/or electrolytes have buffering zones for partly reducing and gradually introducing lithium ions into the anode for lithiation, to prevent lithium ion accumulation at the anode electrolyte interface and consequent metallization and dendrite growth. Various anode active materials and combinations, modifications through nanoparticles and a range of coatings which implement the improved anodes are provided.
