TDK Corporation is a Japanese company that manufactures, distributes, and sells electronic components and devices. It is the world’s leading electronic components and devices company that has high magnetics technology. This company became the first component manufacturer in India for iPhone batteries towards the end of last year.

Now the news is that TDK Corporation has managed to develop a a material for solid-state batteries with 100 times higher energy density.

Nearly 100 times greater energy density than TDK’s conventional solid-state batteries

A higher energy density means more energy storage within less space inside a device. So, in theory, it may offer significantly longer battery life to compact battery-powered devices like smartphones and wearable products like TWS earbuds, smartwatches, and smart rings.

We are talking about a new solid-state battery technology that will offer an energy density of 1,000 Wh/L, which is nearly 100 times greater than the energy density of TDK’s conventional solid-state battery.

TDK has managed to develop a material for the new solid-state battery with a significantly higher energy density than TDK’s conventional mass-produced solid-state batteries (Type: CeraCharge). It has reportedly been possible due to the use of oxide-based solid electrolyte and lithium alloy anodes. The company aims to enhance the capacity of the batteries through multi-layer lamination technology and expand its operating temperature range with the help of the production engineering technology they have accumulated in the electronic components business.

According to the company, the new high-energy density solid-state batteries will also be safe to use. The use of oxide-based solid electrolytes is something that makes the new batteries “extremely safe”. The company mainly focuses on applying its new high-density batteries in compact wearable devices. Notably, the company also intends to replace the traditional coin cell primary batteries, which you cannot recharge. This will also comply with the EU battery regulations, which require rechargeable batteries. So, we can also expect TDK’s new solid-state battery technology to contribute to the reduction of environmental impact.

The company is committed to beginning the mass production of the battery cell and packaging structure as early as possible. However, the company didn’t share an exact timeline related to the development.

India is becoming a key manufacturing hub for Apple. The Cupertino-based tech giant has been ramping up its efforts to make iPhones in the country since 2016. This year marked the first time the non-pro iPhone 15 models were made in India ahead of their debut and the same were also sold on the launch date. Now there is a major new progress on the local production of iPhones as Apple will start making Li-ion batteries in the country. 

Apple to make iPhone batteries in India

iPhone batteries will be made in India by TDK Corp. The Japanese electronics manufacturer is one of Apple’s global suppliers. The company will set up a 180-acre facility in Manesar, Haryana and it will create thousands of several thousand jobs. The cells manufactured at the facility will be supplied to Apple’s li-ion battery assembler Sunwoda Electronics which already operates in India. 

This is a major development as TDK will become the first component manufacturer for the iPhones in the country. Apple’s local production of iPhones in India does not mean that it manufactures the core components required for the smartphone in the country. Instead, the company sources them from China and assembles in India. TDK is reportedly expected to start the commercial production of battery cells in the next 12-18 months. The Japanese company’s entry into making batteries for iPhone in India is a big step towards a fully made in India iPhone. 

Some time back, Indian conglomerate Tata Group took over Wistron’s operations to make iPhones in the country. The Cupertino-based tech giant is aiming to double up its production capacity to 25 percent in India.
