Rechargeable Battery

***

Relevant Background: "A rechargeable battery, storage battery, or secondary cell, (or archaically accumulator) is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid, zinc-air, nickel–cadmium (NiCd), nickel–metal hydride (NiMH), lithium-ion (Li-ion), Lithium Iron Phosphate (LiFePO4), and lithium-ion polymer (Li-ion polymer).."

Market statistics: "The global nickel metal hydride batteries market was worth $0.48 billion in 2019. It is expected to grow at a compound annual growth rate (CAGR) of -3% and reach $0.43 billion by 2023.." (“Nickel Metal Hydride Batteries Market Report 2020 - Market Size to Decline from $480M in 2019 to $430M by 2023", https://www.prnewswire.com/news-releases/nickel-metal-hydride-batteries-market-report-2020---market-size-to-decline-from-480m-in-2019-to-430m-by-2023-301004413.html)

Relevant material on battery explosion: "In most cases an AA battery will only rupture violently if it’s inserted in the wrong direction, exposed to high operating or storage temperatures, mixed with other cells of the wrong type or very different capacities/charge levels, or if a user attempts to (re)charge a cell that isn’t designed to do so. Even outside of these scenarios, though, a very small number of substandard or faulty cells can potentially burst due to less clear-cut misuses. One of the more common causes of leaking or rupture in alkaline AA batteries is running a fresh cell alongside a heavily drained one - on rare occasions, this can end up effectively reversing the polarity on the drained cell, which can quickly cause problems. For most AA batteries, ‘exploding’ usually means a loud ‘pop’ sound and ejection of corrosive materials. When alkaline, NiMH and even lithium AA batteries rupture, the force and heat of the explosion isn’t anywhere near that of, say, an explosive li-ion failure - although it’s still potentially hazardous to users, and the causes should be investigated when safe to do so, along with contacting the manufacturer or supplier....” ("A Complete Guide to AA Batteries", https://uk.rs-online.com/web/generalDisplay.html?id=ideas-and-advice/aa-batteries-guide)

Relevant material on battery leaks: “Battery leakage (commonly known as battery acid) is nasty, corrosive stuff – it can burn your skin, contaminate soil, and of course ruin whatever device it has leaked into. For household batteries, this “acid” is actually alkaline – thanks to the potassium hydroxide chemical make-up. For lead batteries, sulfuric acid is the dangerous residue, which requires a different type of clean-up....” (“What is battery acid”, https://www.energizer.com/about-batteries/what-is-battery-acid)

Relevant Material:  “ About this item 【Effective Gas Leak Detector】 TOPTES PT520A can accurately help you locate the gas leakage of various combustible gases in tight spaces, such as methane, natural gas, propane, LPG, gasoline, etc. *Note: Please allow 30 seconds of warm-up time before the operation 【Flexible Probe Easy to Use】With a 43.5cm flexible gooseneck (bendable in any direction), the portable gas leak detector makes it easy for you to access hard-to-reach areas, such as natural gas pipelines, propane storage tanks, gas fireplaces, basement, RV, and other narrow space. It can be carried anywhere to find leaks no matter outdoors or indoors. 【Visual & Audible Alarm】 PT520A will rapidly respond in 0.5 seconds while gas is detected. Seven colored analog bars and a 75dB audible buzzer help you point out the gas leak location. Both of them increase with combustible gas concentration. Detection range: 50 to 10,000 ppm (*based on Methane) 【User-Friendly Functions】 Activate or c...

*** Relevant Background :  " An  automatic door , also known as an  auto door , is a  door  that opens automatically, without the need for human intervention or usually upon sensing the approach of a person. A person can be detected by microwave pulses,  infrared sensors  , or pressure-sensing pads...  " ( Automatic door - Wikipedia ) ***  Relevant Material :  " THEY HIT PEOPLE MORE OFTEN THAN YOU THINK AND CAN CAUSE SERIOUS PERSONAL INJURY Most of us walk through automatic doors on a regular basis. Most retail stores have some form of automatic doors, whether they are sliding doors, revolving doors, swinging doors, or folding doors. Most people who pass through automatic doors don't think about the fact that they can be struck by the door or trapped between the door and door frame. We expect them to simply open for us and close behind us. But often, that is not the case. When an automatic door hits you, you don’t expect it. It can throw...
