Koalas were declared endangered in eastern Australia on Friday, with more and more koalas dying from disease, habitat loss, and other threats. Earlier, the koala was considered a vulnerable species, and the Commonwealth Department of the Environment changed its protection level to endangered on the east coast of Queensland, New South Wales, and the Australian Capital Territory. Many koalas in Australia are infected with chlamydia. The disease can cause blindness, infection, and infertility. Last year, the Australian Koala Foundation said Australia had lost about 30 percent of its koala population in the past three years. Without immediate action, the species could become extinct by 2050.
Unlike koalas, which are on the brink of extinction, the market demand for lithium battery will grow substantially.
Q: Now, whether it is a mobile phone or other equipment, lithium batteries are generally used. How long will the lithium battery be charged for the first time to activate the lithium battery?
A: The maintenance of lithium batteries has always been a controversial issue on the Internet. There are indeed some rechargeable batteries that require similar "activation" work. This is the earlier nickel-cadmium rechargeable battery and nickel-metal hydride rechargeable battery. These batteries will produce a phenomenon known as the "memory effect". Charging in an incomplete discharge state will easily overcharge the battery. Over time, crystals will grow on the electrode plates, blocking the contact between the electrolyte and the electrode plates. Causing the battery's voltage to drop, making the user feel that the battery will be used up soon. So for both types of batteries, periodically (rather than every time) fully discharging and recharging the battery can mitigate the voltage drop caused by the above reasons.
However, most of the batteries used in our mobile phones and laptops are Li-ion batteries. Lithium-ion batteries can store a lot of energy despite their small size, so they are more and more widely used. Lithium-ion batteries do not need to be activated by deep charging and discharging at the beginning of use because the initialization and testing process of the battery is already completed when the battery is manufactured. Lithium-ion batteries also have no so-called "memory effect" and can be recharged at any time.  The suggestion that a full charge and discharge of a lithium-ion battery be periodically recharged is only for the purpose of calibrating the charge detection devices on laptops and some high-end smartphones, not for any benefit to the battery itself. For devices such as ordinary mobile phones and digital cameras that display the approximate battery level in segments, there is no need to fully charge and discharge them regularly.
What? Some mobile phone manuals also say so? You should know that the battery of a mobile phone is generally not manufactured by the manufacturer of the mobile phone. This kind of writing on the manual may be to remind the user to test whether there is any problem with the battery. In addition, since nickel-cadmium and nickel-metal hydride batteries do need to be activated, this kind of writing on the manual may also be caused by copying the template.

The lithium battery industry has experienced demand expectations driven by the rise and the off-season tired stock driven by the seasonal decline in two rounds of the market. Affected by the COVID-19 epidemic and other factors, inventories of manufacturers continue to accumulate, putting pressure on market sentiment. In addition to off-season factors, the weak trend of lithium battery also reflects the market's concern about the epidemic and some other related enterprises' financial situation.
