Old coal mines can be converted into "gravity batteries" by retrofitting them with equipment that raises and lowers giant piles of sand. Underground Gravity Energy Storage system: A schematic of different system sections. ( Credit: JD Hunt et al., Energies, 2023)
Underground mining workers use Lithium-ion batteries to power various safety equipment including cap lamps, hand-held gas detectors, tracking devices and communication tools.
With the continuous improvement on mine equipment automation level and the progress of battery manufacturing technology, Lithium-ion batteries are widely used in mining transportation, monitoring communication and emergency facilities.
Rechargeable lithium ion (Li-ion) batteries are a type of battery that offer high energy density, which results in enhanced storage capabilities and longer runtimes. This technology is popularly used for portable electronic devices.
A deeper mine would not only produce and store more energy, but would also be more cost effective. Energy storage costs vary from $1 to $10 per kilowatt-hour for UGES, the authors calculate, downright cheap compared to lithium-ion batteries, which currently cost about $150/kWh. Battery prices continue to fall as chemistries improve, however.
This paper designs a kind of lithium-ion battery management system for explosion-proof mining electric vehicle according to GB3836-20210 series standard. And the management system takes STM32F103 as the main controller and LTC6811 as the core, using passive equalization strategy to realize battery voltage equalization.
