因の一つとなっている。Conventional technology and its challenges In recent years, there has been an increasing demand for maintenance-free lead-acid batteries, and lead-acid batteries have been developed to replace the conventional lead-antimony alloy lattice.
Calcium-based alloy lattices are being considered. However, if a battery using this lead-calcium alloy lattice is repeatedly charged and discharged deeply, the capacity may decrease prematurely. This is one of the major factors hindering the growth of society.

われる。Example: On the surface layer of a lead-0.1% calcium alloy plate, per 1C112, A: 1 x 10" pieces, B: 1 x 10" pieces, C: 1 x 1.
After implanting 0'6 phosphorus ions, D: lX10", and E: lXlols using an ion implantation device, an expander process was performed to fabricate five types of lattice bodies with different ion implantation amounts.Furthermore, For comparison, an extended band grid F without ion implantation was also fabricated, and these grids were used as positive electrode grids to fabricate a battery with a capacity of 10Ah in accordance with a conventional method.The fabricated battery had a capacity of 2.5A. Discharge to 1.7 V/cell at IA, 120% of discharge amount at IA
The battery was subjected to a charge-discharge cycle test. Figure 1 shows the results of the charge/discharge cycle test. By implanting phosphorus ions into the surface layer of the lattice, the cycle life performance is improved.
A great effect was obtained when there were 7 pieces. - The reason why batteries using lead-calcium alloys are prone to early capacity reduction is that the corrosion products of the lattice combine with the corrosion products of the lead-antimony alloy lattice, which is very dense and highly reactive. It is believed that this is because the corrosion layer changes into a passive layer of lead sulfate during discharge and prevents the active material from discharging. However, when phosphorus ions are implanted into the lattice surface, the morphology and properties of the lattice corrosion layer change. It is thought that the cycle life performance improved because a passive layer was less likely to be formed during discharge.
なお、実施例ではエキスバンド格子にイオン注入を行な

様の効果が得られる。In the embodiment, an example in which ions were implanted into an expanded lattice was given, but similar effects can be obtained in the case of a cast lattice or a perforated plate lattice.
