Batteries are boring. Banal even. A breakthrough is always around the block but no real upgrades in hand. Being application specific, different for the phone, laptop, car, home, grid and so on; each gets used for only a certain period in the day. So, redundant even.

Now, think of a battery you can use in your two-wheeler, car, carry home as a Powerwall, take to work or pack as a compact box for when you go camping. A universal battery pack so to say. Like today, we use power banks for electronic devices.

Akhil Aryan wants to decouple energy storage systems from applications. “Because the end user gets no value from the actual ownership of the battery,” says the 26-year-old founder of ION Energy. A 20-month-old company in Mumbai, ION has standardised a form factor, say a few 13-inch MacBook Pros stacked on top of each other, so that batteries that back up consumer homes also back up the grid, supercharge electric vehicles, and do much more. “I have a vehicle, I drive 20 km; you have a vehicle, you drive 200 km. But we both go to the gas station to buy gas, not own the gas station.”

So, why own the battery? The answer is a timely argument that goes well with the electric vehicle wave that is sweeping India and other parts of the world. Lithium-ion batteries, the kind used in phones and laptops, are undergoing a historic scale up; there’s a steady fall in the cost of storing energy, nearly 50% drop in the last five years. Still, and Tesla’s Gigafactory notwithstanding, these batteries remain expensive and short of a wholesale economic makeover.

Enter ION.

Its battery pack architecture and the accompanying management software allow it to rapidly build batteries, from 5 Volts all the way up to 1000 Volts. But ION doesn’t call itself a battery company; it’s an energy storage ‘infrastructure’ company. “If you build infrastructure, it eliminates the need for [serving] custom companies,” says Aryan, lifting a ~10 kg, 105x220x355 mm, black case, which, if not for the hardware clutter around, could pass off as a sound box. Branded as Udyr, the battery is being readied for a formal launch at the Hannover, Germany, battery show in May where ION will also announce its first Udyr customer, a European two-wheeler company.

Earlier this month, when ION acquired the seven-year-old French battery management company Freemens SAS, and brought its 32-year-old founder Alexandre Collet as a co-founder, it made two tall claims: It’d “disrupt both the EV and energy storage markets”. With head and shoulders above the market price, $400-500/MWh against the prevailing market rate of $270/MWh, what does ION base its math and confidence on?

What is The Ken?

The Ken is a subscription-only business journalism website and app that provides coverage across two editions - India and Southeast Asia.

What kind of stories do you write?

We publish sharp, original and reported stories on technology, business and healthcare. Our stories are forward-looking, analytical and directional — supported by data, visualisations and infographics.

We use language and narrative that is accessible to even lay readers. And we optimise for quality over quantity, every single time.

What do I get if I subscribe?

For subscribers of the India edition, we publish a new story every weekday, a premium daily newsletter, Beyond The First Order and a weekly newsletter - The Nutgraf.

For subscribers of the Southeast Asia edition, we publish a new story three days a week and a weekly newsletter, Strait Up.

The annual subscription will get you complete, exclusive access to our archive of previously published stories for your edition, along with access to our subscriber-only mobile apps, our premium comment sections, our newsletter archives and several other gifts and benefits.

Do I need to pay separately for your premium newsletters?

Nope. Paid, premium subscribers of The Ken get our newsletters delivered for free.

Does a subscription to the India edition grant me access to Southeast Asia stories? Or vice-versa?

Afraid not. Each edition is separate with its own subscription plan. The India edition publishes stories focused on India. The Southeast Asia edition is focused on Southeast Asia. We may occasionally cross-publish stories from one edition to the other.

Do you offer an all-access joint subscription for both editions?

Not yet. If you’d like to access both editions, you’ll have to purchase two subscriptions separately - one for India and the other for Southeast Asia.

Do you offer any discounts?

No. We have a zero discounts policy.

Is there a free trial I can opt for?

We don’t offer any trials, but you can sign up for a free account which will give you access to the weekly free story, our archive of free stories and summaries of the paid stories. You can stay on the free account as long as you’d like.

Do you offer refunds?

We allow you to sample our journalism for free before signing up, and after you do, we stand by its quality. But we do not offer refunds.
