Confectionery Making and Batteries: Batteries use stainless steel mesh as a current collector for both poles. Stainless steel mesh and sponge air electrodes work well together.
When a battery uses aluminum foil and a stainless steel mesh current collector, the battery will show more than 1.1 volts for a longer period of time. In the end, the voltage drops to about 0.4 volts.
Are sponge electrodes and crepe separators the key to ingenuity? The effect of iron salt or India ink soaked into the sponge, the way crepes are baked, powder, salt, and chewy texture may have something to do with the electrical characteristics.
I'll try to set a goal of one hour of LED lighting with two batteries in series; it seems to light up if there is more than 1.5 volts.
If the batteries can be charged for about an hour, they should be able to discharge and light. If the charge is too long, there is a risk of short circuit ignition.
I put a separator crepe between the sponge and the aluminum, so I think the risk of short circuit during charging is reduced.
The conductivity of the separator is also a concern.
I heard that sulfuric acid groups tend to increase conductivity. I'm going to try mixing myouban and iron sulfate.
I will try making agar and crepes for a while. I will also make sweets for eating at the same time.
【菓子作りと電池】電池はステンレスメッシュで両極の集電体にする。ステンレスメッシュとスポンジ空気極とは相性がいい。
アルミニウム箔を使う電池で、集電体をステンレスメッシュとすると1.1ボルト以上を示す時が長くなる。結局は0.4ボルト程度まで下がるのだが。
スポンジ電極とクレープセパレータが工夫しどころか？スポンジに染み込ませる鉄塩や墨汁の効果、クレープの焼き方、粉、食塩、モチモチ感と電気特性とは関係がありそう。
直列二本の電池でLED１時間点灯を目標にしてみる。1.5ボルト以上あれば点灯するようだ。
充電が１時間ぐらい出来るなら、放電点灯も出来るだろう。充電が長いと短絡発火のリスクがある。
スポンジとアルミの間にセパレータクレープを入れたので充電時の短絡リスクは下がってると、思う。
セパレータの導電性も気になる。
硫酸基が導電性を上げやすいらしい。みょうばん、硫酸鉄を混ぜてみる。
しばらくは寒天やクレープ作りしてみる。食べる方の菓子作りも並行してやる。
