Years back, the Samsung Galaxy Note 7 gained notoriety due to battery fires in multiple instances. Since that time, similar isolated occurrences have transpired. Despite the focus on faulty batteries, the majority of lithium-ion batteries remain secure.

Lithium-ion cells engage in a sophisticated chemical interaction involving a negative and a positive electrode. The negative electrode consists of a lithium-carbon compound, while the positive is cobalt oxide, although many are moving away from cobalt. These compounds interact safely under control, supplying energy to devices. Nevertheless, an uncontrolled reaction can lead to problems such as melting earbuds. Disruptions to this equilibrium can arise from excessive heat, physical damage, and incompatible chargers.

Here are three safety guidelines for batteries:

1. Steer clear of inexpensive cords, chargers, and outlet adapters.
2. Make sure batteries aren’t subjected to extreme heat (above 110°F).
3. Frequently check batteries for any damage.

Avoid cheap wall adapters, cords, and chargers as they’re often problematic. Those low-cost options on Amazon? Not worth the risk. They reduce expenses by compromising on insulation and safety. A low price doesn’t equate to guaranteed safety; choose reputable brands.

Heat remains another issue. It can result in a range of problems concerning both discharge and safety. Stay away from heat and keep an eye on battery temperature during charging. Overheating while charging could signal potential issues. Additionally, be vigilant about swollen or irregularly shaped batteries.

The US Saw a Notable Increase in Battery Demand Last Year

The US Saw a Notable Increase in Battery Demand Last Year

In 2025, the United States saw a historic rise in energy storage, as detailed in a freshly released solar industry report on Monday. This boom in battery storage signifies a considerable milestone for clean energy amid the renewable-unfriendly second term of the Trump administration and suggests that utilities may be modifying electric grids to meet increasing demand across the country.

The report, issued by the Solar Energy Industries Association (SEIA), corresponds with recent findings from Bloomberg New Energy Finance, showcasing a comparable surge in battery development. As per SEIA, the United States added 57 gigawatt hours of new energy storage in 2025, representing nearly a 30 percent rise from the prior year. This capacity is enough to supply power to over five million homes each year.

The report predicts a 21 percent market growth by the conclusion of this year, with an additional 70 gigawatt hours anticipated in 2026. These statistics sharply contrast with less than a decade ago when storage on the grid amounted to only around half a gigawatt.

Batteries have demonstrated considerable political endurance. Tax incentives for wind and solar were cut last summer amid legislative challenges to renewables, yet faced opposition from Republican lawmakers in regions with clean energy initiatives. Nonetheless, battery tax credits largely remained unharmed.

In spite of the federal administration’s position on renewables, batteries and solar experienced considerable advancement in certain conservative states last year. Texas stands out, where solar energy constituted over 15 percent of summer demand, exceeding coal for the first time. SEIA projects that Texas will outpace California this year in terms of gigawatt hours of storage deployed.

Jigar Shah, from the advisory firm Multiplier and a former director of the Department of Energy’s Loan Programs Office, points out that Texas’s independent and deregulated power grid favors solar and batteries over alternative solutions, notwithstanding White House opposition. Recent surveys reveal that MAGA voters back solar power, and prominent individuals like Katie Miller have voiced support for solar energy.

“Texas fundamentally ignores cultural prejudices,” Shah states. “‘Heed the market signals. Construct whatever you wish, whether it’s coal plants or batteries.’ Batteries received the most financial backing.”

While solar and batteries thrive in Texas, the majority of battery installations last year were standalone, not linked to particular solar projects, which is a positive trend for grids coping with heightened demand.

Generally, US energy grids utilize only about 50 percent of their available energy on a daily basis. This intentional underutilization guarantees capacity for peak demand days. Deploying batteries at all levels of the grid aids in harnessing surplus energy during off-peak hours to mitigate waste.
