New Sony battery reportedly gets 40% better life

New Sony battery reportedly gets 40% better life
Batteries are one of the biggest bottle-necks to more innovation with mobile devices. While there have been great strides in fast charging, batteries can't last longer without getting bigger, and there's a size limit to comfortable smartphones (though manufacturers could skew thicker for better battery rather than always going for thinness.) But, Sony may have made a bump.

The big change is rather than lithium-ion, which has been the standard for electronics batteries since 1991, Sony is working on a new high-capacity battery based on a sulfur compound. Normally, the electrode in sulfur-based batteries dissolves into the electrolyte too fast during each charging cycle, which decreases the capacity of the battery. But, Sony claims it has found the solution to this problem (double meaning alert!), and can build batteries with 40% more capacity using the sulfur compound. 

This would mean that in the best case scenario, a phone like the Nexus 6P would be able to have a 4500mAh battery the same physical size as the current 3220mAh battery; the Samsung Galaxy S6 could have a 3750mAh battery rather than 2550mAh; and, the Apple iPhone 6 could have 2530mAh battery rather than 1810mAh. 

Of course, it could also mean that manufacturers would make devices thinner and keep the same size batteries, but that possibility gets our rage spiking out of control.

in 2020. So just another story about batteries.

Yep... Not entirely sure why R&D and speed of release for battery tech hasn't been amped up. The focus on processing power vs power consumption and heat has been awesome, but along the way someone forgot to spend money on battery tech.

I work at a Lithium Ion battery plant in Michigan, R&D is always going on...

but it takes wayy long time to release new battery product.. maybe because they need to throughly check battery charge cycle, capacity durability, explosion chance, etc :-/

Not really, we know within 4 months if the battery we are testing is what we are looking for. The thing that takes time is getting the battery certified in other countries. It took several months to get our LTO cell(also can be called a battery, typically several cells are put together in a battery pack) certified in China so that we could sell them to HK. But now we have to make a new LTO cell because our suppliers could not give us enough material to make enough to meet our order, so new suppliers means we have to go through testing again with several different variants trying to get the performance that we want. The cycle life on all of our cells is amazing, with our LTO we can still retain near 100% of original capacity after 16,000 cycles. And these cells also support rapid charging. A full cycle is from 100% down to 0% and then back up to 100% again.

for which phone you are making the batteries?

The LTOs are 215mm by 215mm they are for hybrid/electric buses and stationary applications.

I wonder how much of that revolves around not bumping heads with some patent troll.

patent trolls are the real dead lock for innovation

Sony and Samsung are the gold standard when it come to cell phone batteries.

Battery tech is far above what it was. Think about what your phone does, how long it lasts. Nothing could do this 5yrs ago without a larger increase in battery size.

... R and D should better continue and be faster than normal because, we need better battery technology...

I think that the first manufacturer to come out with a battery that really noticeably breaks new ground will sell many devices, and may well even be forgiven if some of the other components in such a device are less than cutting edge. Personally if it were possible, I would be happier to see dramatic new battery tech improvements than the incremental processor speed increases we see today. I need greater battery capacity right now more than I need additional processing power that, frankly, I seldom use fully anyway.

Now would be a good time for that Korean dude to pop out and rant about Sony.

If the battery technology is advancing slowly, at least they could make other things like SoCs and displays more power efficient but good step for sony to discover new raw material combinations.

My Z3 Compact battery is easily good for two days.

Better battery, thinner phone and battery, same day or two durability.

Nexus 6p has a 3450mAh battery. Do some research for better reputation PA!

Have you seen the battery life benchmarks on Nexus 6p?

No I haven't. But I own a Nexus 6p and I'm very happy with it's battery. I get around 4.5 hours of screen on time from the morning of day one until evening of day two. Sync is set to push, I watch some videos on youtube, do some texting and surf a lot. So given that it has a 5.7" screen, it's very good.

Sony among the first to commercialize Lithium Ion battery and they will do it again.
