An anode-free solid-state battery may include a cathode layer; an anode current collector layer; and a separator layer between the cathode layer and the anode current collector layer. The battery can further include an anti-dendrite layer located between the separator layer and the anode current collector layer. The battery further includes an interfacial bonding layer located between the anti-dendrite layer and the anode current collector layer. The interfacial bonding layer increases an amount of electrical connectivity between the anode current collector layer. A first amount of adhesion between the interfacial bonding layer and the anode current collector layer can be greater than a second amount of adhesion between the anti-dendrite layer and the interfacial bonding layer.

An anti-dendrite anode-free solid-state battery (SSB) can include a cathode layer; an anode current collector layer; and a lithium gel separator layer between the cathode layer and the anode current collector layer. An anti-dendrite layer may also be present located between the lithium gel separator layer and the anode current collector layer. The anti-dendrite layer can help discourage dendrite formation.

A phase-change electrolyte separator layer can include a non-reactive scaffold that has open spaces. A lithium liquid may be used that transitions into a lithium gel, the lithium liquid can include a mixture of a polymer additive, a cross-linker additive, a lithium salt; and a solvent. The lithium liquid with the polymer additive and the cross-linker additive can be filled into the open spaces within the non-reactive scaffold. The lithium liquid can then be converted into a lithium gel within the non-reactive scaffold following an application of heat while the lithium liquid is within the open spaces within the non-reactive scaffold.

Various arrangements for compressing a cylindrical battery cell are presented herein. The cylindrical battery cell may be wrapped in a buffer material. The buffer material may then be compressed using a compression mechanism. The buffer material may uniformly distribute pressure applied to the buffer material to a curved sidewall of the cylindrical battery cell.

Isostatic press devices and processes for cylindrical solid-state batteries

A battery cell having a layered pressure homogenizing soft medium for liquid/solid state Li-ion rechargeable batteries. The battery cell of the present technology includes one or more battery pouches, a pressure mechanism external to the battery pouches that applies a pressure to the battery pouches, and a layered pressure homogenizing soft medium that is displaced between the battery pouches and the pressure mechanism. By using a number of pressure homogenizing medium layers, each with a specific range of thickness and within a range of physical properties, the battery pouches displaced between the pressure homogenizing medium layers are evenly pressurized by the mediums due to pressure applied by the pressure mechanism to within a desired range of pressure. The pressure applied to the battery pouches by the pressure homogenizing medium is monitored by a pressure sensor, such as a two-dimensional pressure sensor. If the pressure to the battery pouches is not within a desired pressure range, a controller can control the pressure mechanism to adjust the pressure to the mediums and battery pouches to bring the pressure within the desired range.

A rotor of the permanent magnet rotating electric machine includes a rotor core, a plurality of magnets, and magnetic slits. Each of the magnetic slits is formed in a core region being a region between magnets of the plurality of magnets, and a gap. The magnetic slits are regions having a lower magnetic permeability than a magnetic permeability of the core region. One end of each of the magnetic slits, which is closer to an outer periphery of the rotor, is positioned in a portion of the core region on the same direction side as a direction of a force in a circumferential direction of the rotor, and another end closer to the rotation axis center of the rotor is positioned on the magnetic pole center or in a portion of the core region on a side opposite to the direction of the force.
