Battery Manufactory

"Battery repair artifact", "One move to restore 100% capacity", "Old battery refurbished as new" - similar advertisements are flooding the Internet, attracting countless users who are troubled by battery life issues. But can batteries really "rejuvenate"? Repair or IQ tax? Is refurbishment legal? This article will clear the fog for you and provide rational solutions based on battery chemistry principles and industry truths. I. The essence of battery aging: irreversible chemical decay Whether it is a mobile phone lithium battery , an electric vehicle power battery or a lead-acid battery, the essence of aging is an irreversible chemical reaction of the internal materials: Lithium battery: electrolyte decomposition, positive electrode material structure collapse, lithium dendrite growth. Lead-acid battery: plate sulfidation, electrolyte stratification. NiMH battery: electrode passivation, active material shedding. Conclusion: Battery ...

Lithium batteries in medical devices are the "invisible guardians" that maintain life - pacemakers rely on them to keep beating, portable ventilators rely on them to maintain oxygen supply, and insulin pumps use them to accurately control the amount of medicine. However, the maintenance of these batteries is far more complicated than that of mobile phones or laptops, and the slightest carelessness may endanger the patient's life. This article will deeply analyze the particularity of lithium batteries in medical devices and provide scientific maintenance methods to help patients and medical staff extend the life of the equipment and ensure safety. I. The particularity of lithium batteries in medical devices 1. Implantable devices vs. external devices Implantable devices (such as pacemakers): Battery type: Mostly lithium-iodine (Li-I₂) batteries, with high energy density and low self-discharge rate (annual self-discharge <1%). Lifespan: Usually 7-15 yea...

Battery health is a key indicator of battery performance, which directly affects the battery life and service life of the device. Whether it is a mobile phone, laptop or electric car, learning to check the battery health can help you find problems in time and avoid the embarrassment of sudden power outages. This article will introduce the battery health detection methods of different devices in detail and provide tips to extend battery life. I. Why do you need to pay attention to battery health? Batteries will naturally age with use, and reduced health will lead to: Shortened battery life (such as charging a mobile phone from once a day to twice a day). Slower charging speed (increased battery internal resistance). Degraded device performance (some mobile phones will automatically reduce the frequency due to battery aging). Safety hazards (bulging, leakage and even fire risks). Battery Health is usually expressed as a percentage, 100% is a new battery, and below 80% i...

Whether it is a spare battery for a mobile phone, an idle battery for an electric car in winter, or a dry battery stored at home, improper long-term storage will cause the battery performance to deteriorate or even become scrapped. According to statistics, about 30% of battery damage is caused by incorrect storage methods (data source: Battery University). This article will provide scientific storage methods based on the different characteristics of lithium batteries , nickel-metal hydride batteries, and dry batteries to help you keep your batteries healthy to the maximum extent. I. General storage principles (all battery types) a. Clean battery contacts Wipe the positive and negative electrodes with alcohol cotton pads to prevent oxidation and poor contact. b. Stay away from extreme environments Temperature: The best storage temperature is 15°C-25°C (high temperature accelerates aging, and low temperature may cause the electrolyte to freeze). Humidity: Keep the relative...

From equipment at Antarctic research stations to solar energy storage systems in the Sahara Desert, the stability of lithium batteries is directly related to the success or failure of missions in extreme environments. But can lithium batteries work properly in extremely cold -40°C or extremely hot 50°C? How will their performance change? Is there a risk of explosion? Based on battery chemistry principles and cutting-edge technology cases, this article will analyze the true performance of lithium batteries at extreme temperatures and explore how to break through the constraints of natural laws. I. Lithium batteries at low temperatures (-40°C): the challenge of freezing a. How does low temperature "seal" lithium batteries? Electrolyte solidification: The viscosity of conventional lithium battery electrolytes increases sharply below -20°C, lithium ion migration is hindered, and internal resistance soars. Capacity drop: At -40°C, the capacity of ordinary lithium...

It is not uncommon for lithium batteries (such as mobile phones, cameras, and drone batteries ) to be accidentally soaked in seawater during outdoor activities, seaside trips, or emergencies. The high salinity and conductivity of seawater may cause serious damage to the battery and even cause safety hazards. This article will provide you with a detailed analysis of the correct handling process and scientific principles of lithium batteries soaked in seawater to help you avoid risks and reduce losses. I. Take immediate action: safety first, avoid secondary damage a. Cut off the power supply and remove the battery Do not continue to use: seawater entering the battery may cause a short circuit, causing heating, expansion, or even fire. Remove the battery carefully: If the battery is embedded in a device (such as a mobile phone), it needs to be turned off and carefully disassembled to avoid squeezing the battery shell. b. Avoid direct contact with the skin Battery electrolyt...
