TDK to Mass-Produce Smartphone Lithium-Ion Batteries with 15% Increased Charging Capacity by Summer 2025

According to Nikkei Asia, TDK Corporation, a leading global manufacturer of electronic components, plans to begin mass production of a lithium-ion battery for smartphones with a 15% increase in charging capacity by summer 2025. This was revealed by TDK President Noboru Saito in an interview ahead of CES 2025 in Las Vegas. The move aims to address the increased power consumption of smartphones driven by the rise of generative AI technology and further solidify TDK's leading position in the mobile phone battery market.

The surge in power consumption stems from the increased computing power and functionality of generative AI-powered smartphones launched by companies like Apple. To meet this growing demand and provide smartphone manufacturers with a more competitive solution, TDK has focused on improving battery energy density. This breakthrough was achieved through the adoption of advanced material technologies.

The core technology behind TDK's new lithium-ion battery lies in replacing the traditional graphite anode material with silicon. Silicon boasts a higher theoretical energy density, allowing for greater power storage in the same volume and significantly increasing charging capacity. This not only extends battery life but also reduces battery size for the same capacity, offering greater design flexibility for other internal smartphone components.

The reduced battery size is particularly crucial for foldable smartphones. Thinner and lighter batteries better suit the design requirements of these devices, enabling longer usage times while maintaining a slim and portable form factor. TDK's ambitions extend beyond the smartphone market; the company plans to apply this technology to other electronic devices like laptops and tablets, providing more efficient power solutions across a wider range of products.

While silicon anode batteries currently represent a small portion of TDK's small lithium-ion battery sales, the company has established a clear mass production plan. To ensure sufficient production capacity, TDK plans to establish a new battery production facility in Haryana, India, in 2025, further enhancing its manufacturing capabilities to meet growing market demand.

TDK is confident about its future development and plans to launch a new battery with a 40% capacity increase by March 2027. This demonstrates TDK's ongoing innovation in battery technology and its keen understanding of market trends. According to Techno-System Research, TDK currently holds approximately 40% of the global market share for lithium-ion batteries used in mobile phones, indicating strong industry reputation and market acceptance.

In fiscal year 2024, TDK's battery business accounted for over 50% of the company's overall sales, with an impressive operating profit margin of 17%, significantly higher than other electronic components like MLCCs (Multilayer Ceramic Capacitors). This highlights the battery business as a critical profit growth driver and a cornerstone of the company's overall strategy.

TDK's mass production of this 15% improved lithium-ion battery showcases its technological prowess and positively impacts the smartphone industry. As generative AI becomes more prevalent in smartphones, the demand for longer battery life intensifies. TDK's breakthrough technology will effectively alleviate smartphone battery anxiety, providing consumers with a superior user experience.

This technology also unlocks new design possibilities for smartphone manufacturers. Smaller batteries free up space for other functional modules, enhancing overall smartphone performance and functionality. This could include larger camera sensors, more powerful processors, or innovative features to meet the diverse needs of consumers.

TDK's success sets a benchmark for other battery manufacturers. Improving energy density will be a key challenge for all battery manufacturers in the future, and TDK's early lead will provide a significant competitive advantage, further strengthening its global leadership in the lithium-ion battery market.

TDK's announcement is not only a demonstration of its technological confidence but also a proactive response to future market trends. It underscores TDK's leading position in technological innovation and market competition, making a significant contribution to the advancement of the smartphone industry. With continued technological progress, TDK is poised to deliver even more advanced and reliable battery products, providing more sustainable and stable power support for our digital lives. This marks a new era for smartphone battery technology, offering consumers longer battery life and a slimmer, more portable smartphone experience. It also provides smartphone manufacturers with more possibilities, driving continued innovation and development in the smartphone industry. TDK's ongoing investment and technological breakthroughs will contribute to a better digital future.
