This 89-year-old manufacturer of electronic components has a revolutionary new product. TDK (OTCMKTS: TTDKY) is Apple's major electronics supplier. The company has announced a breakthrough in solid-state battery technology that could significantly enhance the performance of wearable devices.

TDK's innovation targets various devices that come into direct contact with the human body, such as wireless earphones, hearing aids, and smartwatches. The company plans to produce these batteries using an all-ceramic material made of oxide-based solid electrolytes and lithium alloy anodes.

One of TDK's key goals is to replace existing coin cell batteries, small stainless steel discs commonly used in portable devices, with its solid-state battery technology.

Energy density is a crucial factor in battery performance, as it determines how much energy can be stored in a given space. Solid-state batteries are seen as a potential game-changer in the industry due to their ability to store more energy than traditional lithium-ion batteries and charge more rapidly.

TDK has developed a material for its small solid-state batteries that boasts an estimated energy density of 1,000 Watt-hours per liter (Wh/l), approximately 100 times greater than TDK's current conventional solid-state batteries.

The solid electrolytes used in TDK's batteries are touted as "extremely safe.” This is a significant advantage over traditional battery technologies. Additionally, the smaller size and higher capacitance (ability to store electric charge) of these batteries could contribute to the development of smaller devices while potentially providing longer operating times.

What The Analysts Are Saying

TDK's solid-state battery breakthrough holds promise for enhancing the performance and safety of wearable devices. This aligns with the growing demand for compact, high-capacity, and reliable power sources in the consumer electronics market.

How is Wall Street reacting to TDK’s battery innovation? Surprisingly, there aren’t many analysts weighing in. Should this technology be successful and widely adopted, TTDKY could prove to be very popular among investors. Currently, there are two buy ratings on the stock, which includes analysts at Jefferies.
