Its safety and basic performance far surpasses that of conventional products.

Product Name = Lithium Iron Phosphate Oxide Battery

Enables Safe Energization even if it has a Hole or is Flooded

It is not an exaggeration to say that batteries are now installed in all kinds of machinery, including automobiles, industrial machines, PCs, smartphones, and home appliances. Batteries make our lives rich and comfortable. On the other hand, they can cause various major and minor accidents, such as expansion, heat generation, spontaneous fires, and generation of toxic gases.

The safe "lithium iron phosphate oxide battery" from TRC TAKADA is a solution to minimize these risks. Furthermore, it has a long life and contributes to the reduction of burdens on the environment. This product has been confirmed to have no risk of expansion, heat generation, or fire even if punctured by a nail, and energized safely after subsequently being submerged in seawater. There is no risk of toxic substances leaking out of a hole. Since it generates very little heat under normal use, cooling fans can be eliminated, making it possible to use in an enclosed space.

It has no risk of generating toxic gases because no organic substances are used in the manufacturing process, and it uses iron oxide, which is stable in molecular structure. These features make this product outstandingly safe, defying common sense in batteries.

Long Life and Low Charge Frequency

In addition, the basic performance greatly surpasses that of conventional products. The charge-discharge cycle, which means the battery life, of lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries is about 500 to 800 times, 1,000 times, and 1,200 to 2,000 times, respectively. Compared to them, this product’s charge-discharge cycle is 3,000 times or more. Though the initial cost of installing the lithium iron phosphate oxide battery is higher than that of lead-acid batteries, the total cost can be kept low given its long life.

Also, the self-discharge rate of lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries is 1.5 to 2%, 10 to 30%, and 5 to 10% per month, respectively. On the other hand, this product has a self-discharge rate of less than 3% per year. This product is expected to show stable performance for a long time while reducing the charging frequency.

Supporting Modification of Power Sources for Industrial Machinery, as well as Prototyping and Mass Production

TRC TAKADA is now building a mass production systems for its lithium iron phosphate oxide battery in Japan and other countries in Asia. The company has another strength in that it can deal with the entire process from prototyping to mass production, and it has a proven track record of introducing the product in the automobiles, ships, and drones outside of Japan. In Japan, the company is handling development requests from safety-critical firefighting-related institutions. As well, it is receiving numerous requests to change the power source of industrial machinery from lead-acid batteries to lithium iron phosphate oxide battery.

This product has the potential to make every type of machinery evolve to next-generation machinery. If you are experiencing challenges with your products' batteries or considering updating your plant's power source, this product is an attractive option.
