Recently, Japan's HAMAKEN WORKS (Hamada Electric) launched a product called "JOVY SSPB (semi-solid mobile Battery)", referred to as "SSPB". The battery uses a quasi-solid electrolyte technology containing 3% liquid.
The SSPB has a high energy density of 280Wh/kg, which makes it smaller and lighter than ordinary liquid electrolyte mobile power supplies and lithium iron phosphate batteries, while having a larger capacity. In terms of safety, the quasi-solid battery is designed so that it will not burn even in the case of spikes, drops or strong shocks, and users do not need to worry about the risk of leakage or explosion.
In addition, the SSPB is able to achieve 2,000 charge and discharge cycles (80% capacity retention), which increases the cycle life by more than four times compared to existing liquid polymer batteries. The use of solid electrolytes helps to inhibit the generation of lithium lamps, thereby extending battery life and improving safety.
The SSPB comes in two capacity models, the 5,000mAh model retails for 6,980 yen (about 324 yuan), while the 10,000mAh model retails for 8,980 yen (about 417 yuan). The product is available in black, white and champagne gold.
Solid-state batteries are increasingly used in consumer electronics such as wearables and drones as a high-security portable power source.
In terms of wearable devices, solid-state batteries can meet the needs of wearable devices such as smart watches and health monitoring devices because of their miniaturization, thinness and flexibility.
In July this year, Japan's Tokyo Electro-Chemical Industry Co., LTD. (TDK) announced the development of the next-generation solid-state battery CeraCharge material, using oxide solid electrolyte and lithium alloy anode, with an energy density of 1000Wh/L, about 100 times the energy density of its traditional solid-state battery.
The breakthrough is expected to have applications in a variety of wearables, such as wireless headphones, hearing AIDS, small electronic devices such as smartwatches, as well as environmental sensors and alternative button batteries.
