The present invention relates to a battery and a method of manufacturing the same, and more particularly to a battery using chlorophyll to generate electrical energy and a method of manufacturing the same.

In recent years, portable electronic devices such as mobile phones, portable cameras, notebook computers, digital cameras, PDAs, CD players, etc. have emerged, and they are demanding small size and light weight, and as a portable lightweight power source - battery It is also receiving attention. Battery types include dry batteries, nickel-metal hydride batteries, lithium batteries and fuel cells. A brief description of common batteries is given below.

Most of the dry batteries used daily are zinc-manganese batteries, also called carbon-zinc batteries. The outer casing of a carbon zinc battery is generally made of zinc, which can serve as both a battery container and a negative electrode of the battery. Carbon zinc battery is from liquid Leclanch The battery has evolved. Conventional or general-purpose carbon-zinc batteries use ammonium chloride as an electrolyte; super- or high-energy carbon-zinc batteries are usually carbon-zinc batteries using zinc chloride as an electrolyte, which is an improved version of a generally inexpensive battery. The positive electrode of a carbon zinc battery is mainly composed of powdered manganese dioxide and carbon. The electrolyte is a paste solution formed by dissolving zinc chloride and ammonium chloride in water. Carbon-zinc batteries are the cheapest primary batteries, so they are the first choice of many manufacturers, because the batteries sold by these manufacturers often need to be distributed. Zinc-carbon batteries can be used in low-power devices such as remote controls, flashlights, toys or transistor radios.

However, when the carbon-zinc battery is used for a period of time, since the metal zinc is oxidized to zinc ions, the zinc casing is gradually thinned. Therefore, zinc chloride solution can often leak out of the battery. The leaked zinc chloride tends to make the surface of the battery sticky. Some old batteries have no leakage protection. The service life of zinc-carbon batteries is relatively short, and the shelf life is generally one and a half years. In addition, even if the battery is not used, the ammonium chloride in the battery is weakly acidic, and it can react with zinc, and the zinc casing will gradually become thinner.

The lithium battery often mentioned in the 3C industry is actually a lithium-cobalt battery. The generalized charge and discharge lithium battery refers to a graphite anode, a cathode using cobalt, manganese or iron phosphate, and an electrolyte for transporting lithium ions. Composition. A lithium-ion battery can be used as a negative electrode in lithium metal or lithium intercalation. The development of the lithium battery industry has been concentrated in the 3C industry for more than 20 years, and it is rarely used in the market for larger energy storage and power batteries (in the case of large currents). This market covers pure electric vehicles and hybrid vehicles. , medium and large UPS, solar energy, large energy storage batteries, electric hand tools, electric motorcycles, electric bicycles, aerospace equipment and aircraft batteries. The main reason is that the lithium-cobalt cathode material (LiCoO ₂ , which is the most common lithium battery) used in lithium batteries in the past cannot be used in applications requiring high current, high voltage, high torque, and withstand puncture, collision, high temperature, low temperature, etc. Special circumstances such as conditions, and more importantly, have been criticized for failing to meet people's absolute requirements for safety.

At the same time, lithium-cobalt batteries can not achieve the purpose of fast charging and completely avoid secondary pollution. Moreover, it is necessary to design a protection circuit to prevent overcharging or over-discharging, otherwise it will cause explosion and other dangers, even if the explosion of Sony battery causes global The brand NB industry has invested heavily in recycling.

In addition, the price of cobalt is getting higher and higher, and the Congo, the world's largest producer of cobalt, is in trouble. The price of cobalt is rising. The powder of lithium-cobalt batteries has risen from the original price of 40 US dollars to 60-70 US dollars due to the rising price of cobalt. Lithium iron phosphate powder is priced at 30 to 60 US dollars per kilogram depending on the quality.

NiMH batteries are designed from nickel-cadmium batteries. In 1982, OVONIC Corporation of the United States requested the patent of hydrogen storage alloy for electrode manufacturing, which made this material pay attention to. In 1985, Philips of the Netherlands broke through the problem of capacity decay of hydrogen storage alloy during charge and discharge, and finally made nickel-hydrogen battery. stand out. At present, there are more than 8 nickel-hydrogen battery manufacturers in Japan, and nickel-hydrogen batteries are also produced in Germany, the United States, Hong Kong and Taiwan. The market has responded well. Moreover, the pollution caused by nickel-hydrogen batteries is much smaller than that of nickel-cadmium batteries containing cadmium. Therefore, nickel-cadmium batteries have been gradually replaced by nickel-hydrogen batteries.

A fuel cell is a device that uses a fuel to chemically generate electricity. It was first invented in 1839 by Grove, England. The most common proton exchange membrane fuel cell fueled by hydrogen and oxygen is purely fuel-free and environmentally friendly, and produces pure water and heat after power generation. It was applied to the US military in the 1960s. In 1965, it was applied to the Gemini 5 spacecraft of the American Gemini Project. There are also some notebook computers that are starting to study the use of fuel cells. However, since the generated electricity is too small and cannot provide a large amount of electric energy in an instant, it can only be used for smooth power supply. A fuel cell is a dynamic mechanism in which a battery body and a fuel tank are combined. Fuel selectivity is very high, including pure hydrogen, methanol, ethanol, natural gas, and even the most widely used gasoline, can be used as fuel for fuel cells.

Regardless of the new environmentally-friendly carbon-zinc, alkaline and secondary batteries, small amounts of mercury or other heavy metals such as zinc, manganese and lithium are used in the process, and contaminating substances are used in raw materials and processes. It is harmful to the environment and the human body.

Currently widely used lithium batteries are unstable electrochemical devices, which may cause an explosion if the manufacturing process, improper packaging, and operation at low loads. Therefore, multiple complicated protection mechanisms are needed, such as protection circuits, vent holes, isolation films, etc., wherein the protection circuit is used to prevent overcharging, overdischarging, overloading, and overheating; the venting holes are used to prevent excessive internal pressure of the battery; It has high puncture resistance to prevent internal short circuit and can melt when the internal temperature of the battery is too high, preventing lithium ions from passing through, blocking the battery reaction, and raising the internal resistance (to 2kΩ).

The positive electrode of lithium battery (such as Li _1-x CoO ₂ ) and the negative electrode (Li _x C) have less and less lithium ore, which makes the price rise rapidly.

Lithium batteries begin to rapidly decrease in performance and life in outdoor environments or environments with slightly higher temperatures.

Nickel-cadmium batteries or nickel-hydrogen batteries have a memory effect and are easily degraded due to poor charge and discharge.
