I didn’t realize “battery scientist” was a real job until I was 22 and graduating with a physics degree.

Strange, isn’t it? We’re surrounded by batteries in phones, laptops, toys, but usually only notice them when they stop working.

Imagine building a career out of the tech inside. ⚡🔋

The “80% vs 100% charge” debate misses the bigger point.

Unless you’re running NMC, topping up isn’t the main concern.

The real risk is charging at rates your battery was never designed to handle. ⚡🔋

When people hear battery industry, they imagine scientists in labs or engineers at benches.

But it’s bigger than that: process engineers, technicians, industrial engineers, biz dev, and sales all keep the ecosystem alive.

It takes all kinds to power the future. ⚡

Batteries 101:

– Voltage = measured outside the cell
– Potential = what’s happening inside, with the ions

Same number, different framing. Which term do you use without even thinking? 💡

Lithium-Sulfur batteries shine on gravimetric energy density (Wh/kg).

But volumetric energy density (Wh/L) is the sticking point: low packing density + liquid electrolyte.

In EVs and aviation, where space is tight, Wh/kg isn’t enough.

Battery safety discussions often stop at the cell level.

But firmware in the BMS and foreign-made power electronics may present equal, or greater, risks.

That’s the real frontline of battery safety today.

EV battery fires 🔋🔥 get a lot of dramatic headlines—but in reality, they’re far less common than the news cycle makes them seem.

Learning how they start (and how to safely charge, store, and use your EV) goes a long way for peace of mind.

What’s one EV battery safety tip you always follow?

With IRA funding slowing and private capital tightening, the battery industry faces harder choices.

EVs, grid storage, data centers, aviation — not every segment will scale equally fast.

Smart strategies focus on markets where the technology is indispensable. ⚡

End-of-life battery pathways remain unclear in much of the US and EU.

Policy gaps in handling, shipping, and repurposing keep circularity stuck.

Until those gaps close, recycling and reuse will lag far behind the need. ♻️

Chemistry often gets all the attention in batteries.

But careers (and impact) scale on more than cells:
• Data → insight
• Safety by design
• Systems integration
• Communication that aligns teams + supply chains

This is how the industry moves forward.

The FAA projects eVTOLs could be flying fans to the Super Bowl by 2027. The real bottleneck? Batteries.

• Endurance (flight time)
• Charge speed (readiness)
• Safety (non-negotiable)

Aviation won’t scale without breakthroughs here. Which factor do you think matters most for eVTOL adoption?

Jill Pestana | Battery Expert 🔋 @jillpestana.bsky.social · 15d

Battery teams collect enormous volumes of performance, testing, and manufacturing data.

Yet most use only a fraction of it, the rest remains siloed.

Competitive advantage won’t come only from better cells, but from better data use. 💡📈

Leaving an unsupportive lab isn’t failure.

It’s recognizing that growth matters more than endurance.

Lessons learned:
– Don’t try to fix what isn’t yours
– Own your strengths where you are
– Work with collaborators who value you

Batteries may be one of the only bipartisan priorities:

• Electrification
• Energy storage
• National security

The real challenge isn’t politics — it’s talent. Are we training the workforce that can actually deliver?

The line between a “quick test” and a “long-term study” is thinner than we admit.

When do you call it? ⏳⚡

Jill Pestana | Battery Expert 🔋 @jillpestana.bsky.social · 21d

The myth of “one perfect battery chemistry” has always been wrong.

• Data centers → endurance
• eVTOLs → power
• Grid storage → cost + scale

The opportunity: matching chemistry to application. Which chemistry do you think is most underrated right now?

What’s the difference that allows for fast charge? Higher Si content? Different pack voltage?

Are they planning to do LFP in EU instead of Li-S?

Controversial take: We don't need better batteries for most applications.

We need better battery management systems and smarter charging algorithms.

Software > hardware sometimes 💻⚡
