摘要： A lithium cell and method for producing, wherein an electrode contains a first polymer and a separator contains a second polymer having a melting point below that of the first polymer. The first polymer may be the same in the anode and the cathode, or one electrode may contain the first polymer and the other electrode contain a third polymer. The first polymer may be a homopolymer, and the second polymer may be a copolymer, and may contain the first and/or third polymers as components. In one embodiment, the first polymer is polyvinylidene fluoride (PVDF) and the second polymer is PVDF and hexafluoropropylene. The relatively high melting point first and/or first and third polymer(s) permits high temperature drying of the electrodes, which facilitates water removal and thereby increases cell life. It also reduces swelling of the porous structure, which facilitates permeation of the electrolyte.

摘要： The present invention, a cell layer edge support, provides longer battery cell life while minimizing the possibility of shorts within the cell. More specifically, an edge support layer is positioned around at least a portion of the smaller electrode, either the anode or the cathode, in the cell to define a supporting perimeter comparable to the perimeter of the larger electrode. The support layer generally comprises a polymeric material which helps to absorb pressures exerted on the cell layers during packaging. The anode, cathode, support layer and a separator layer placed between the anode and the cathode may be joined to form a battery. Preferably, a plurality of cells having the support layer may be joined to form a higher energy, longer life battery.
摘要翻译： 本发明，电池层边缘支撑件提供更长的电池寿命，同时使电池内短路的可能性最小化。 更具体地，边缘支撑层围绕电池中的阳极或阴极的较小电极的至少一部分定位，以限定与较大电极的周边相当的支撑周长。 支撑层通常包括聚合物材料，其有助于吸收在包装期间施加在电池层上的压力。 放置在阳极和阴极之间的阳极，阴极，支撑层和隔离层可以连接形成电池。 优选地，具有支撑层的多个电池可以被接合以形成更高能量，更长寿命的电池。
