エキスパンド格子体が開発されたが未だ十分ではない。[Problems to be Solved by the Invention] In the above electrode plate, for example, the positive electrode active material expands and contracts with temperature changes and charging and discharging of the battery, so strain is applied to the bone portions 3a and tuberosities 3b of the mesh portion 3. is added. Ii! i section 3
Due to its structure, portion b is more likely to be distorted by the above strain force than bone portion 3a, and if the battery is repeatedly charged and discharged due to deep charging and discharging, continued use at high temperatures, or repeated charging and discharging cycles due to long-term use. As the current collector 1 weakens, the node 3b is damaged due to permanent strain generated in the node 3b connected to the current collector 1, and good conduction between the current collector 1 and the mesh part 2 is impaired. Sexuality may be impaired. As a result, good current collection at the electrode plates is not achieved, resulting in durability problems such as a decrease in battery capacity and a shortened battery life. In order to improve this, an expanded lattice using a lead alloy sheet containing antimony has recently been developed, but it is still not sufficient.

This damage rate and -9= are determined by fixing the part below the third stage node 3b from the non-deployed part (current collecting part 1) of the lattice, and
A test was performed three times in which the current collecting part 1 side of the grid body was bent at an angle of 606 degrees for 1 second by applying a pressing force to the surface a, and the boundary between the non-deployed part and the R opening part was This figure shows the leakage of damage caused by the damage.

耐える強度が低いものと思われる。As shown in the table above, processing form A has a high breakage rate when using seams with different sb contents, whereas processing form B has a high breakage rate. The results showed that sheets using sheets with a content of 2% by weight or less had a much lower failure rate than the former. The sheet using a sheet with an Sb content of 2.5% by weight has a high breakage rate for both processed forms A and B, but this is because this sheet has a lower Sb content than the other two types of sheets. Since it is hard, it is thought that its strength to withstand bending tests is low.

Single cell storage batteries R' and V-, each with a 5-hour rate capacity of 43A11, were manufactured by forming anode plates with the same type of lattice body obtained using 40A3.
Figure 4 shows the results of a Nicle test in which the battery was repeatedly discharged for 0 minutes and charged at 2.5A for 10 hours. The vertical axis in the figure is the rate of change in capacity with respect to the initial capacity. As seen in the figure, battery V- has better durability against many charge/discharge cycles than battery R-. The main cause of deterioration of the anode plate in battery R-, which had a life cycle, was corrosion near the boundary between the non-deployed part and the developed part of the grid.
