A flame retardant solid electrolyte comprising an ion conductive polymer matrix having moieties capable of imparting flame retardance to the polymer matrix and ether bonds in the molecule and an electrolyte salt dispersed in the polymer matrix. The flame retardant solid electrolyte may be one which comprises a non-ion-conductive polymer matrix and a liquid electrolyte consisting of an electrolyte salt dissolved in a solvent therefor, which is dispersed in the polymer matrix. The flame retardance-imparting moieties are derived from halogen or phosphorus-bearing compounds.

Flame-retardant solid electrolytes

In order to improve the charge-discharge energy density of a lithium secondary cell with a nonaqueous electrolyte having such a construction that a metallic compound capable of occluding or releasing lithium is used as an electrode active material, lithium or a lithium alloy is used as a negative electrode material and a solution of a lithium salt is used as an electrolyte, the microstructure of the metallic compound is rendered acicular. Further, a lithium-containing metallic compound grown into such a columnar form that has the angle .THETA. to the normal of the surface of the substrate of 0.degree..ltoreq..THETA.&lt;90.degree. is used as the electrode active material.

Non-aqueous electrolyte lithium secondary cell

A semiconductor device with a current detecting function in which in place of an external resistor for detecting an operation current such as drain current or collector current of a device such as an FET or bipolar transistor, a probe electrode is formed in proximity to the device depletion layer to connect therethrough with the device channel to generate a probe voltage corresponding to the operation current.
