    摘要： A square lithium secondary battery includes a wound body in which a collective sheet in which a positive electrode sheet and a negative electrode sheet overlap each other with a first separator interposed therebetween is wound while a second separator is put inside the collective sheet. An active material mixture layer on one or both surfaces of at least one of the positive electrode sheet and the negative electrode sheet includes a region with a plurality of openings and a region with no opening. At least a bent portion of the collective sheet is covered with the region with the plurality of openings.

    摘要： This disclosure relates to a battery and a method for its manufacture. An example method includes forming a substrate having a first surface, the first surface having a plurality of pores. The pores may be configured to house lithium metal. The method includes incorporating lithium metal into at least a portion of the plurality of pores. The lithium metal may be incorporated into the pores via a pre-lithiation process, which may include electroplating of lithium metal into the porous substrate. The method also includes forming an electrolyte disposed between the first surface of the substrate and a cathode. The electrolyte is configured to reversibly transport lithium ions via diffusion between the substrate and the cathode. The method also includes forming the cathode. Some embodiments may provide the substrate to jointly serve as an anode and electrically-conductive current collector.

    摘要： A semi-solid electrode includes a first porous substrate and a second porous substrate stacked together to form a current collector, and a semi-solid electrode material embedded in the current collector. The semi-solid electrode material includes a suspension of an active material and a conductive material disposed in a non-aqueous liquid electrolyte. The porous substrates are at least partially disposed within the suspension such that the suspension substantially encapsulates the porous substrates. Each porous substrate in the current collector defines a pitch, and the two pitches of the two porous substrates in the current collector can be shifted with respect to each other by 30% to 70% of the pitch so as to reduce polarization effect.

    摘要： Certain nickel hydroxide active cathode materials for use in alkaline rechargeable batteries are capable of transferring >1.3 electrons per Ni atom under reversible electrochemical conditions. The specific capacity of the nickel hydroxide active materials is for example ≧325 mAh/g. The cathode active materials exhibit an additional discharge plateau near 0.8 V vs. a metal hydride (MH) anode. Ni in an oxidation state of less than 2, such as Ni1+, is able to participate in electrochemical reactions when using the present cathode active materials. It is possible that up to 2.3 electrons, up to 2.5 electrons or more may be transferred per Ni atom under electrochemical conditions.
