No. A more accurate statement is that semi-solid batteries significantly reduce fire and thermal runaway risk by reducing flammable organic solvents, lowering leakage and vaporization, and suppressing internal short-circuit triggers. However, every battery system still requires BMS, structural protection, proper installation, and correct use.

It's true that LiFePO₄ is more stable than NCM. However, conventional LFP cells still rely on liquid electrolytes. Under extreme conditions – such as high temperatures, overcharging, short circuits, or physical damage – the organic solvents in these liquid electrolytes can still release flammable gases.Semi‑solid technology addresses precisely this material‑level risk. By replacing part of the liquid electrolyte with a gel‑state alternative, it further reduces the likelihood of flammable gas generation and leakage.

A nail penetration test simulates an extreme internal short circuit caused by a sharp object piercing the cell. If a semi-solid cell shows no fire, no smoke, and no explosion after penetration, it indicates more stable safety performance under internal short-circuit conditions.

BMS is system-level protection for monitoring, warning, and control. Semi-solid technology is material-level safety that reduces the conditions for flammable gas formation, leakage, vaporization, and internal short circuit inside the cell. They are complementary, not substitutes.

They are suitable for solar energy storage scenarios where home safety is a priority. Plug-in home batteries are close to living spaces and may face sunlight, temperature changes, and daily load fluctuations over time. Semi-solid batteries improve the safety foundation at the material level, matching users’ need for long-term peace of mind.
