摘要： PURPOSE: To provide a temperature difference secondary battery capable of displaying better characteristics by increasing an electro motive force with the further expansion of the applicable temperature range of a high temperature electrode. CONSTITUTION: High temperature is set for one side of an electrode 2 and low temperature for the other side of an electrode 1 to set a temperature difference between both electrodes 2 and 1, and an electro motive force is thereby generated. An ion exchange film 3 is introduced in an electrolyte to provide a secondary system, so as to make the concentration of electrolytes 6 and 7 separated from each other with the film 3 and existing at both sides thereof controllable, depending on electrochemical reaction. Furthermore, a pair of auxiliary electrodes 8 and 9 are laid at both sides of the film 3 even during a charging process with the main electrodes 2 and 1. Also, electrolyte charging space 16 is formed on the end of the high temperature electrode 2 at a position above an electrode setting level. As a result, a temperature range up to a high level can be applied and a temperature difference secondary battery having excellent battery characteristic can be provided.

摘要： PURPOSE:To eliminate need of a charger, and increase energy density. CONSTITUTION:A secondary battery comprises a positive electrode 6, a negative electrode 7 having a type-n semiconductor part 7c and a metal negative electrode member 7a which are integrally formed, electrolyte 8a including oxidizer and redox ion pairs as positive electrode active material, and a battery case 12 in which the positive electrode 6, negative electrode 7, and electrolyte 8a are contained. The battery case 12 is provided with a light receiving part 12a for applying light to the type-n semiconductor part 7c of the negative electrode 7. The negative electrode 7 is provided with an electrolyte separation film 9 to restrict transmission of the redox ion pairs existing on the side of the type-n semiconductor part 7c to the side of the negative electrode member 7a. Because of this charging by light at the type-n semiconductor part 7c, need of a charger can be eliminated, and because oxygen is used as energy source for oxidizing the negative electrode member for discharging, energy density can be improved. A simple structure of a two-electrode system of the positive electrode and the negative electrode can thus be provided.

摘要： PURPOSE:To provide a method for quickly and easily judging the degrading condition of a lead-acid battery. CONSTITUTION:Correlating relation between a charging ratio which is a ratio of charge capacity to discharge, capacity, and the capacity of a storage battery, is measured so as to be determined first. Next, a lead storage battery which is a subject lead storage battery for judging degradation, is discharged at a constant discharge current for the definite period of time for obtaining discharge capacity in a step (b), and the subject lead storage battery for judging degradation is charged at constant charging voltage with the maximum charging current determined for the definite period of time for obtaining charge capacity in a step (c). A charge rate which is a ratio of discharge capacity thus determined to charge capacity, is then computed in a step (d), and the storage battery capacity of the lead-acid battery for judging degradation is estimated based on the charge rate thus computed by using correlation relation set in advance in steps (e) and (f), so that its degradation condition is thereby judged. This constitution eliminates a need for discharging the battery to discharge end voltage unlike a degradation judging method based on a former capacity test, and thereby enables the degradation of the lead-acid battery to be judged simply in a short time. Moreover, manhours required by these tests for judgement, and electrical loss entailed by charge/discharge can be lessened.
