Song Ziqiang's battery is directly used in the 60s of the 19th century, when France's Le Cranchet invented the carbon-zinc dry battery.

This is an acid zinc-manganese dry battery, which uses a zinc cartridge as the negative electrode and is amalgamized to make the surface properties more uniform, so as to reduce the corrosion of zinc and improve the storage performance of the battery.

The cathode material is a mixed paste composed of manganese dioxide powder, ammonium chloride and carbon black.

A carbon rod is inserted in the middle of the cathode material to act as a conductor for the eliciting current.

Between the positive and negative electrodes there is a reinforced layer of isolated kraft paper, which is impregnated with an electrolyte solution containing ammonium chloride and zinc chloride, and the upper part of the metallic zinc is sealed.

Zinc and manganese are essential stocks in the non-ferrous metal reserves of Liuqiu Island...... This is, of course, the credit of Wang Defa, who once used the crucible smelting method to make alloy steel a little bit, but there were too many failures, and there were also successes.

All these written materials and non-ferrous metal reserves were left to Song Ziqiang.

Immediately afterwards, Song Ziqiang directly made a light bulb made of bamboo charcoal as a filament.

He injected carbon dioxide directly into the bulb and then applied some yellow phosphorus to eliminate any remaining oxygen in the bulb.

After connecting the dry battery, it really brightened, and it could work continuously for thousands of hours.

Wu Dapeng asked curiously: "Why do you want to make it the size of a pigeon's egg?" ”

"This is the easiest size to machine......"

Well, Wu Dapeng said that his memory is not good, and he compromises production and processing.

Wu Dapeng said: "Are we going to build a formal power plant? ”

"I don't have an electric motor yet, what power plant do you want?"

"Then why not make an electric motor?"

"Without a power plant, how can I make a powerful magnet?"

Well, Wu Dapeng understands that he is caught in a paradox...... Natural magnets can be processed into generators with low output rates, and if they reach the level of electric motors, they need to be developed little by little.

Again, everything has to be done slowly.

In fact, Song Ziqiang has been working out these devices for a short time, for more than half a year.

It wasn't until a year later that civilian magnet telephones began to appear in the Badaohe area...... Although the price of the five-digit number is expensive, and the service fee is also expensive, it appeared for about a year and finally broke through 10,000 doors......

It wasn't until two years later that it began to operate in the folk of Lin'an City in the Great Song Dynasty, and within half a year, it broke through 3,000 gates!

Of course, that's all for later.

When Song Ziqiang was busy with his career, others were not idle.

Wanshida began to build its own ironclad ships.

With the technical equipment that is already available, Wanshida does not want to simply nail the iron armor to the wooden plank, which is much less solid.

Since the wooden hull is basically unable to withstand the steam engines and larger large guns that must be installed, the wooden hull cannot withstand the addition of a heavier armor...... So, the design concept of simply staring at the iron armor is ridiculous.

Theoretically speaking, it is now possible to roll cast iron rails, cast iron keels, medium and high pressure steam boilers that are not leaky, and ironclad giants that are not leaky can be made.

As for the rolling of the armor belt, it is not difficult, a hot rolling technique will do it.

The ironclad ship designed by Wanshida was not all steel, which he thought would be a waste of materials.

Not counting the Shandong region, the steel output of Liuqiu Island itself has reached the steel output of the Great Song Dynasty, and the quality is better than theirs, but it is still in short supply.

There are so many places where steel is needed now...... And their crucible smelting method has reached the extreme, and the only way to change the smelting method is to change it.

However, there are many limitations, so you can only use steel where it is more needed.

If only the current sailboats were sufficient, and completely at the highest level in the world...... In this case, it is indeed too advanced to use all steel on ironclad ships, and it is not applicable.

The Wanshida design features an iron-hulled hull with a 10 mm iron plate on the inside and a 10 mm wrought iron armor on the outside riveted with nuts and bolts.

Rivet technology mentioned that they will be completely hot riveting technology...... This is widely used in the industrial areas of the island of Liuqiu.

This needs to be connected to the two wrought iron decks respectively drill holes, and then the rivets are burned red, through the holes in the steel plate, hit the rivets with a die, quickly let the rivet head form, and when the rivets cool down, the two wrought iron decks will be automatically connected more closely by using the principle of thermal expansion and cold contraction.

In the middle of the two layers of iron armor are staggered 200 mm of hardwood timber and filled with a large amount of balsa balsa wood.

In order to save weight, the entire interior of the hull is basically made of hardwood structure, and a large number of balsa wood is also used.

Wanshida did not design any cast iron ramming...... Even with such a hull, a slight touch of the wooden ships of this plane will make them shatter.

The entire ironclad battleship is 130 meters long, 119 meters long between the waterlines, and 19 meters wide. 7 meters, the length-width ratio is about 7.23, the depth is 8.2 meters, the displacement is expected to exceed 10,000 tons, and the sail area is about 5,000 square meters.

The crew on the battleship was about 700 people.

The ironclad battleship has an armor belt on each side, and these two armor belts are encircled from the bow to the stern to increase its ramming ability.

These two armor belts are still riveted to a mesh hull support structure based on a cast-iron keel and supplemented by a cast-iron rib system, which can also be used to protect the non-watertight compartments inside.

The other hull parts are also riveted directly to this support structure with iron plates.

The entire ironclad battleship is made of cast iron keels, which gives it a strength that exceeds all wooden keels.

The battleship admiral was armed with forty breech-loading guns of different calibers.

Although the steam engine power equipment was used, the three masts and corresponding sails were still maintained, which could be used just in case.

The weight of the entire battleship is expected to exceed nine thousand tons...... Driven by pure steam engine power equipment, it will reach a speed of fifteen knots.

If the steam engine unexpectedly stops and is powered only by sails, then the speed can only reach a pitiful section that can compete with the speed of a sail oar...... However, it is better to have the protection of sail power than nothing.

After making the model, Song Ziqiang shook his head and said, "You don't have confidence in my steam-powered equipment......"

Of course not, Song Ziqiang's medium- and high-pressure steam power equipment has been shut down four times and overhauled twice when it has been in operation for half a year...... What is gratifying is that it has rough skin and thick flesh, and it can be used again after repairing.

This will be a big ship of more than 10,000 tons, and the construction period may exceed two years.

Song Ziqiang patted his chest and promised: "It will definitely not take two years, you don't look at the development of our industry with a static eye, it will take a year at most!" ”

Wan Shida said lightly: "I think this Magna Carta-level ironclad battleship can protect our sea power for a hundred years......"

"A hundred years? You're too pessimistic, it's okay for 500 years! ”

Of course, the cost of this ironclad battleship is huge, but even better is that it may improve the shipbuilding skills of the entire Federation Empire.

Zhang Anguo asked people to put the model of the ironclad battleship in the pool, and used the technique of close shooting to take a large photo of it and hang it in his office.

Everyone who came to his office was amazed at it, this was the true strength of the Federal Empire.
