摘要： PURPOSE:To obtain satisfactory capacity from the initial stage of charge- discharge cycle and increase discharge capacity by containing an electrolyte comprising KOH in an electrolyte solution and specifying the concentration of the electrolyte. CONSTITUTION:When a hydrogen occlusion alloy is used as a main material of negative electrode 2 of hydrogen battery, an electrolyte comprising KOH or LiOH is contained in an electrolyte solution and the concentration of electrolyte is specified to 2.5-6.5 normal. Thereby, since the penetration rate of the electrolyte into the pore of electrode is increased, the capacity of the battery is increased and performance in the initial stage of charge-discharge cycle is improved.

摘要： PURPOSE:To obtain identical electric discharge capacity and long life as those of conventional product by making hydrogen occlusion alloy powder whose surface is coated by palladium a main constitution material. CONSTITUTION:In hydrogen occlusion alloy electrode, a main constitution material is produced by forming palladium coated layer on the surface of hydrogen occlusion alloy (such as rare earth metal group, titanium-manganese group, iron-titanium group etc.) powder used in conventional hydrogen occulsion alloy electrodes. As palladium is excellent in oxidation proofness comparing with rate earth metal and Mn, Fe, the palladium coated layer protects internal hydrogen occlusion alloy powder from oxidization. And hydrogen occlusion alloy expands or is powdered finely when it absorbs hydrogen, but the palladium coated layer absorbs expansion of synthetic granule inside or prevents slip-off of finely-powdered alloy granule. Therefore, longer life of the hydrogen occlusion alloy electrode can be attained by using hydrogen occlusion alloy powder having palladium coated layer as a main constitution material.

摘要： PURPOSE:To obtain a storage battery having an hydrogen occluded alloy negative electrode with a positive and a negative electrode capacity condition of objective one without making hydrogen atmosphere at all the processes by adding alcohol and lithium hydroxide into an electrolyte. CONSTITUTION:Alcohol, which is selected from lithium hydroxide or methanol or propanol, is added to an electrolytic liquid which is consisting of potassium hydroxide or sodium hydroxide as sub-component of it. Alcohol corresponding to negative electrode capacity to be charged excessively is added into the electrolytic liquid, and when the charging is performed, a positive electrode is not being charged, on the contrary, since the negative electrode is being charged ordinary, the proper charging condition of the positive and negative electrode is realized. And, by adding designated amount of lithium hydroxide into the electrolyte, the produced CO3 ion is precipitated as Li2CO3, and the reducing of the CO3 ion concentration can be obtained.
摘要翻译：目的：通过向电解液中加入醇和氢氧化锂，从而在所有方法中获得具有正极和负极容量条件的吸氢合金负极的蓄电池，而无需氢气氛。构成：将选自氢氧化锂或甲醇或丙醇的醇加入到由氢氧化钾或氢氧化钠作为其副成分的电解液中。向电解液中添加与负极容量过量相对应的醇，进行充电时，不进行正极充电，相反，由于负极正在充电，所以适当的充电条件实现正极和负极。并且，通过向电解质中添加指定量的氢氧化锂，所生成的CO 3 2-离子作为Li 2 CO 3析出，可以得到CO 3 2-离子浓度的降低。
