Introduction

I.Apple‘s “Battery Gate” Event

On December 29th morning, Apple issued a statement to apologize for its controversial decision to slow down the speed of older iPhones in order to protect the battery and promised that the cost of those out-of-warranty iPhone battery replacement will drop down to $29 。

In its statement, it said that “We’ve been hearing feedback from our customers about the way we handle performance for iPhones with older batteries and how we have communicated that process. We know that some of you feel Apple has let you down. We apologize. There’s been a lot of misunderstanding about this issue, so we would like to clarify and let you know about some changes we’re making.

First and foremost, we have never — and would never — do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades. Our goal has always been to create products that our customers love, and making iPhones last as long as possible is an important part of that.”

Apart from this apology statement, Apple also made a separate article in its official website, "A Message to Our Customers about iPhone Batteries and Performance," which said some of the battery technology with the processor as well as the function problems, here are the main points for you to do briefly read:

About the battery:

  • 1. All the rechargeable batteries are consumable components that will decrease their chemical efficiency as they age. The use of device can also affect the performance of the battery lifespan. 

  • 2. There are many factors that affect the battery life, Apple put forward the concept of "chemical age".

At the beginning of that article, Apple popularized electrochemical knowledge, hoping to let users understand the current status of lithium batteries.

About Frequency Reduction:

  • 1. Aging Batteries can not provide heavy loads, especially at low battery conditions, which can cause the device to  shut down suddenly.

  • 2. Apple thinks it is unacceptable to shut down unexpectedly, so this kind of decision has been made (that is the processor frequency reduction);

Apple acknowledged that the iOS 10.2.1 system (released in January 2017) will reduce the frequency of the older models and listed the models: iPhone 6/6 Plus, iPhone 6s / 6s Plus and iPhone SE; and iPhone 7/7 Plus in iOS 11.2; however, they also emphasized "the dynamic management of instantaneous performance spikes (ie Frequency Reduction) only when needed."

In this “Battery Gate”, we noticed the electrochemical knowledge about batteries. Batteries play an important role in our daily life. Lighting, mobile phones, cameras, watches, microphones, laptops, electric cars, new energy vehicles, electric toys, remote controllers ... all of these devices need batteries. There are many types of batteries, lithium batteries, solar batteries, fuel cells, air batteries, lead-acid batteries, carbon batteries ......Here let me introduce you more about batteries. First, it is about battery types.

IV..Several Battery applications

battery application--The Most Comprehensive basic Knowledge of Battery in History

Among the many types of batteries, which battery should be used? In general, household appliances, such as radios, clocks, toys, remote controls and so on are using primary batteries. Many portable electronic products such as: laptops, cell phones, electric cars, etc., will use secondary batteries. In practical application, there is usually a battery or several batteries in series-parallel to form a battery pack.

4.1 Electric vehicle battery

4 kinds of power batteries are used for electric vehicles: valve-regulated lead-acid maintenance-free batteries, colloidal lead-acid batteries, Ni-Mh batteries and lithium-ion batteries. The majority of electric vehicles are equipped with lead-acid batteries because of their low cost and cost-effective.

4.2 Laptop battery

NiCd batteries are the first batteries to be introduced, but as this battery had a "memory effect" and had to be discharged before each charge, it is inconvenient to use. So it was soon replaced by  NiMH batteries. Not only did NiMH have no "Memory effect", but its power capacity can be inproved to more than 10% per unit weight.

4.3 Mobile Phone Battery

Mobile phone batteries are generally using lithium batteries and nickel-metal hydride batteries. mAh is the unit of battery capacity.

VI.Precautions for Battery Use

precautions1--The Most Comprehensive basic Knowledge of Battery in History

  • 1. Electrical appliances and battery contacts should be cleaned, if necessary, wiped with a damp cloth, correctly labeled according to polarity after dried .

  • 2. Do not mixed use old and new batteries; Do not mixed use the same type but different electrochemical types or brands of batteries.

  • 3. Primary battery can not be heated or charged, otherwise it may explode.

  • 4. Do not disassemble the battery, do not heat the battery, do not short-circuit the battery (the positive and negative battery direct access by wire)

  • 5. Remove the battery in time if not in use, turn off the power after use.

  • 6. Do not discard batteries, separate them from other wastes as much as possible.

VII.Harm of Waste Batteries and Their Recycling

  • Harm of Waste Batteries

In waste batteries, the metal mercury can dissolve in fat, which will cause central nervous diseases, teratogenicity, mutagenic, carcinogenic and even death among animals. Cadmium will soften bones, cause bone deformation, if serious, it will cause natural fracture and even death; salt of zinc will result in protein precipitation, which has a stimulating effect on the skin and mucous membranes; lead will mainly lead to anemia, neurological dysfunction and kidney damage, inhibition of hemoglobin anabolism; Nickel dissolved in blood, which will damage the central nervous system, causing vascular variability; Manganese can cause neurological dysfunction, comprehensive dysfunction and even mental symptoms.

waste-hazard--The Most Comprehensive basic Knowledge of Battery in History

95% material of the waste batteries can be recycled, especially heavy metals. Waste lead-acid batteries can recycle 50 ~ 60kg lead. There are more mature technology to deal with recycling of cadmium batteries in foreign countries. About 20kg of metal cadmium can be recovered from 100kg waste battery containing cadmium. We can see the great practical significance of recovery of heavy metal resources. However, domestic waste battery recycling is still disputed. At present, only lead-acid batteries (car batteries) have their own waste battery recycling system, which other types of batteries don’t have.



Analysis
