⚠️ New Galaxy 7 Suffers a Serious LiON “Runaway Flame-Out” πŸ”‹πŸ”‹ Shipments Halted ⚠️ Major Recall βš οΈβš οΈ

September 3, 2016

βš οΈπŸ”‹βš οΈ Samsung Electronics Co Ltd’s mobile business suffered a Huge blow Today as reports of Burning and Exploding LiON Batteries forced the Delay of all shipments of New Galaxy 7 smartphones; this also knocked Down $7 Billion from its public stock-market value.

βš οΈπŸ”‹βš οΈ Samsung said it is investigating the reports of their premium smartphones catching fire and exploding. South Korea’s Yonhap News said sixteen explosions were reported by consumers. It cited pictures of severely damaged phones shared with local online communities, social media and YouTube. Some of the photos and accounts have been verified. Samsung yesterday halted Galaxy Note 7 shipments in South Korea, in spite of the phone’s massive preorder sales success.

βš οΈπŸ”‹βš οΈ Samsung did not confirm its reasoning, but due to the many recent battery explosion Reports from Customers convinced Samsung to suspend All Shipping to local telecom temporarily. In the meantime, new reports Today, indicate that Samsung is “engineering” a massive Galaxy 7 recall of over 2,400,000 units sold since August 19th, in South Korea, and that LiON Battery worries are indeed a Real Problem. Samsung insists that these events should not affect the planned launches of the Galaxy 7 for China and Europe, markets that will receive the handset as expected, with a different LiON Battery.

βš οΈπŸ”‹βš οΈ Samsung the global smartphone leader, told Reuters late Wednesday evening that shipments of the Galaxy 7 have been Halted for quality control testing [of its LiON Batteries and Charging apparatus]; also noted, Shipments to South Korea’s top three mobile carriers had been halted, until further notice.

βš οΈπŸ”‹βš οΈ Faults with the new premium flagship Galaxy 7 Note will likely deal a major blow to Samsung, the South Korean giant, which was counting on the Galaxy Note 7 to maintain its strong mobile earnings momentum against Apple Inc’s ($AAPL) new iPhones 7 and iPhone 7 Plus to be unveiled in only a few Days.

βš οΈπŸ”‹βš οΈ Samsung’s Galaxy 7 has spent $Millions for Prime-Time pre-Launch advertising. Think about it, researching the issue for the power exchange between the LiON Charger, and Galaxy 7’s internal power management system, and it’s LiON Battery will require some time to isolate the issues. Once the issues are re-engineered, Production is Halted, and All of the already Retail Boxed Galaxy 7 units will have to be fixed and repackaged, before any shipments resume.

βš οΈπŸ”‹βš οΈ Samsung has concluded that faulty LiON Polymer batteries are to blame for the fire & explosions. Samsung SDI is the group within Samsung that makes batteries for the Galaxy Note 7. Samsung SDI produces the LiON battery cell, but the battery-pack Production is out-sourced to other firms. Korean ITM Semiconductor produces the battery pack for the Galaxy Note 7’s that are sold in Korea. ITM’s batteries seem to have been the ones that exploded. Meanwhile, most phones sold in China are going to have battery packs from Chinese company Amperex Technology.

βš οΈπŸ”‹βš οΈ Halting the Galaxy 7 Production and the Product release is Major Buzz-Killer for Samsung, especially given all of the hard-earned and Expensive Excitement that the Note 7 have garnered in recent months.

βš οΈπŸ”‹βš οΈ Apple Current Launch of the iPhone 7 and iPhone 7 Plus puts all the more pressure on Samsung to contain and fix this issue quickly. I would not be surprised if Apple expedited the access to its On-Line Ordering for the iPhone 7. The timing of the Galaxy 7 Flame-Out of their LiON Batteries, Charger and Power Control Circuitry could not have been worse.

βš οΈπŸ”‹βš οΈ For Galaxy 7 the culprit, as is usual, is the LiON battery. It’s why the Note 7 went haywire, fire, and explosion and, why hoverboards are dangerous, and why every few months there seems to be another report of a smartphone or laptop going boom.

βš οΈπŸ”‹βš οΈ The Galaxy 7 incident is unusual largely due to its Huge Scale, {the recall of 2,500,000 Galaxy 7 units, and the immediate halt of all production}, Plus Samsung’s admirably aggressive response. Samsung engineers have unofficially pinned the issue, and experts say it’s a Lithium Ion battery issue.

βš οΈπŸ”‹βš οΈ Thermal Runaway – Introduction: Lithium Ion batteries continue to cause the trouble. All LiON Batteries have three main components in common: an Anode at one “end” – a Cathode at the “other end” – and both are immersed and surrounded in an Electrolyte. A 3.8 DC voltage flows from the Anode to the Cathode, or in reverse direction, driving Lithium Ions from one end to the other, depending if you’re Charging or Discharging the LiON Cell.

βš οΈπŸ”‹βš οΈ Spontaneous Thermal Runaway – There are Two Dangers that can happen with LiON Batteries. The danger is a LiON Cell may be

β€’ Over-Charged which leads to heating the Cell, which may lead to unwanted chemical over-reactions in the Anode
β€’ Over-Discharged which leads to heating the Cell, which may lead to unwanted chemical over-reactions in the Cathode. The cathode contains Oxide which may combine with organic impurities in the electrolyte and may release heat
β€’ Low-Quality LiON batteries, may contain impurities which may be responsible for unpredictable electrolytic. These unwanted chemical reactions have an ominous ring to it, especially when they result in what’s known as a Spontaneous Thermal Runaway
β€’ Spontaneous Thermal Runaway is the result of too much heat being released inside the LiON Cell, that spirals-up and out of control, where the Cell’s internal temperature goes Higher and higher, making the chemical electrolytic reaction go Faster and faster, creating More and more Heat. Once the cell’s internal passes about 400ΒΊF this spontaneous reaction spirals out of control.
β€’ Spontaneous Thermal Runaway occurs when the LiON Cell’s internal temperature crosses over 400ΒΊF – commonly referred in the LiON industry to as “Thermal Runaway.” This should be a frightening notion, because

(1) Billions of Smartphones are in circulation Globally powered by LiON Batteries
(2) Thermal Runaway causes literally a spontaneous “Fire or Explosion in Your Pocket, Purse, Car, Airplane, or Apartment”
(3) As Exothermic Electrolytic reaction crosses 400ΒΊF or 200ΒΊ Celsius, the reaction becomes spontaneous, where the reaction spirals out of control, until it becomes consumed in Flames or Explodes.

βš οΈπŸ”‹βš οΈ The Fix for Spontaneous Thermal Runaway – Without getting too far into the weeds, there a number of obvious issues that can be addressed

(A) Internally LiON cells can be fitted with thermal sensors that can remove the Cell from the Circuit once a temperature of say 300ΒΊF is reached
(B) Manufacturers of LiON cells must implement quality controls to assure Chemical Purity of the Anode, Cathode, and the Electrolyte
(C) LiON Cell engineers need implement more aggressive Heat Dissipation methods to control Cell temperature, particularly in the Electric Car, Automotive industry
(D) LiON Battery engineers are “pushing the envelope” of Energy Density, the practice of pushing more energy capacity into smaller, lighter, containers
(E) For SmartPhones there are two solutions controlling heat dissipation with heat-sinks to the smartphone’s outer-shell, otherwise smartphone engineers attempt to make their chips and circuits more efficient requiring less power to operate
(F) For Electric Cars, Tesla cars travel with a huge 100,000 Watt-Hours of Power in its battery pack [the equivalent of 35,000 cell phone LiON batteries]
(G) Tesla cars, high performance electric vehicles that can have relative Huge Power Discharges white rapid acceleration, or rapid Re-Charging
(H) Accordingly, Tesla has an aggressive heat-dissipation system of pumping fluid Ethylene Glycol around the LiON Cell Modules through hoses to Heat-Exchange [radiator] panels mounted below-behind the Car’s Front Bumper. This temperature control is necessary to maintain safe internal temperatures for all the LiON cells.

As friends, family and students know, I’m an avid and early adopter of iPad since its release April, 2010. When Apple released [November, 2015] the 12.9″ Retina-Display iPad PRO, (having sold a MacBook Pro to Gazelle.com) then purchased the 12.9″ iPad PRO configured with 128GB of Storage, 4GB memory, AT&T connectivity, plus Apple Pencil and Brydge Pro Keyboard Cover, and a DECODED natural leather slip-over protective folio.
